Cecal duplication causing a disappearing abdominal mass in an infant

Duplications of the alimentary tract are rare malformations. A case of a 2-year-old girl with an intestinal intussusception caused by a cystic duplication of the cecum is presented. This case report is justified by its clinical features and the difficult diagnosis, which was only confirmed during surgery. Ultrasonography had documented an abdominal mass that then disappeared and later reappeared, leading to surgical indication. During surgery, the intussusception within the abdomen was reduced, and right hemicolectomy was performed around the mass in the interior part of the cecum and appendix, with ileocolic anastomosis. On resecting the cecum, a cystic duplication measuring 4 x 3 cm was observed, with a granular mucous layer, an ulcerated hole in its interior, and inflammatory reaction. The patient had an uneventful recovery and was discharged on the fourth postoperative day.     

Intussusception of an appendiceal mucocele: Report of a case

A 66 year old Japanese female was admitted to our department for the examination and treatment of a mass in the cecum. She had experienced no symptoms or signs other than a positive test result for fecal occult blood. The mass in the cecum was confirmed by barium enema, colonofiberscopy and CT scanning. The presumptive diagnosis was a submucosal tumor of the cecum, however, a laparotomy subsequently revealed intussusception of an appendiceal mass. An ileocaecal resection with an ileocolic anastomosis was therefore performed and the mass was histologically diagnosed as a mucocele of the appendix. This patient is only the 24th case of intussusception of a mucocele of the appendix to be reported in Japan. A review of the available literature on this condition follows the case report.     

Adult intussusception with cecal adenocarcinoma: Successful treatment by laparoscopy-assisted surgery following preoperative reduction

We report a case of adult intussusception caused by cecal adenocarcinoma that was treated by laparoscopyassisted ileocecal resection following reduction by contrast enema and preoperative colonoscopy.A 68-yearold male with cecal cancer was admitted to our hospital because of colicky abdominal pain after taking a laxative.His abdomen was distended,and a mass was palpable in the right upper quadrant,which appeared as a target-or sausage-shaped lesion by ultrasonograhpy and computed tomography.A contrast enema using water-soluble material showed a cup-shaped filling defect characterized by intussusception in the ascending colon.This round defect with a clear margin was pushed gradually back into the cecum by the enema pressure.Re-occurrence of the intussusception is easilyreleased by colonoscopy.We performed laparoscopyassisted ileocecal resection of a protruding tumor measuring 6.5 cm × 5.0 cm × 3.5 cm from the cecum,with D3 lymph node dissection.Histological examination revealed a well-differentiated adenocarcinoma that had invaded the serosa without permeating the lymphatic or venous capillaries,as well as lymph node metastasis.The postoperative course was uneventful,and the patient has been well without evidence of disease recurrence for 5 years following the operation.Preliminary reduction of adult colonic intussusception before surgical resection is therefore an option in cases of an early and correct diagnosis of intussusception.     

Intestinal schistosomiasis manifesting as colonic intussusception arising from a mucocele of the appendix: Report of a case

We report a case of intestinal schistosomiasis manifesting as colonic intussusception resulting from a mucocele of the appendix, caused by the obstruction of appendiceal outflow by schistosome egg-induced fibrosis. An 81-year-old woman from China presented with a tender right iliac fossa mass and computed tomography (CT) showed intussusception in the ascending colon. Exploratory laparotomy confirmed an appendiceal mass causing intussusception of the cecum into the ascending colon, with the appendix as the lead point, and lymphnode enlargement. We performed a right hemicolectomy for the appendiceal tumor. However, histologic examination revealed schistosoma eggs within the mucosa, submucosa, muscularis propria, and subserosal fat of the appendix, cecum, and ascending colon, and lymph nodes. The absence of dysplasia in the appendiceal mucosa indicated that the mucocele had developed from fibrosis induced by schistosome eggs obstructing the luminal outflow of mucin. Postoperatively, the patient was given praziquantel and recovered well.     

Pheochromocytoma discovered in a pregnant woman: a case report]

A case of pheochromocytoma discovered at pregnancy is reported. The patient was a 27-year-old woman who had no symptoms before pregnancy. A sudden hypertensive attack occurred during vaginal examination at the 36th week of pregnancy. Magnetic resonance imaging (MRI) and ultrasonography showed a right adrenal mass. The level of catecholamine in blood and urine was beyond the normal limit. This patient was diagnosed as pheochromocytoma with pregnancy. Cesarean section was immediately done to avoid hypertensive crisis caused by spontaneous delivery. Blood pressure and blood volume were controlled by an alpha-blocker for one month after delivery, and, then the tumor was removed surgically. Pheochromocytoma with pregnancy is life-threatening for the mother and the fetus because of difficult diagnosis and complex clinical features. Early diagnosis and appropriate treatment are mandatory. Pathophysiological characteristics and the treatment of such specified statics are mainly discussed through our successful achievement.     

Rapidly growing renal angiomyolipoma during pregnancy with tumor thrombus into the inferior vena cava: a case report

A case of renal angiomyolipoma rapidly growing during pregnancy with tumor thrombus into the inferior vena cava is reported. Angiomyolipoma in a 31-year-old woman was incidentally found by ultrasonography. CT scan revealed a fat-containing tumor in the right kidney with 4 cm in diameter. The patient was followed at outpatient clinic without any treatment. Fifteen months later, the post-delivery follow-up CT scan showed that tumor size had grown up to 11 cm in diameter. Although laparoscopic right nephrectomy was tried, open transperitoneal right nephrectomy was performed because the tumor thrombus extending into the inferior vena cava was found during the laparoscopic procedure. Pathological diagnosis was angiomyolipoma of the kidney. There are several reports that indicate angiomyolipoma grows rapidly during pregnancy. Our case demonstrates that careful follow-up is required for angiomyolipoma in women with possible conception and delivery.     

Mucinous Cystadenocarcinoma in the Appendix in a Patient with Nonrotation: Report of a Case

Mucinous cystadenocarcinoma in the appendix is uncommon. An anomaly in the rotation of the intestine is also uncommon in adults. We herein report a case of mucinous cystadenocarcinoma in the appendix in a patient with nonrotation. To the best of our knowledge, this is the first report of appendiceal carcinoma in a patient with an anomaly of intestinal rotation. A 76-year-old woman was admitted to our hospital with left low abdominal pain. Physical examination revealed tenderness with muscle rigidity in the left lower quadrant. The patient was diagnosed to have intussusception by computed tomography and ultrasonography. An emergency operation showed nonrotation and the top of the appendix situated in the left iliac fossa. An appendectomy was performed because of gangrenous acute appendicitis. However, the cut surface of the appendix showed a mucocele measuring 4 × 4 cm in size. It was diagnosed to be mucinous cystadenocarcinoma histopathologically. A right hemicolectomy with lymph node dissection was performed, and no remaining cancer cells or lymph node metastases were found in the resected specimen pathologically. The patient had an uneventful postoperative course. No signs of recurrence have been observed for 23 months since her last operation. Received: January 5, 2001 / Accepted: July 17, 2001     

A case of bilateral renal cell carcinoma showing a rapid course of death in a long-term hemodialysis patient due to polycystic kidney

A case of bilateral renal cell carcinoma in a 42-year-old polycystic kidney male is reported. He had been treated with hemodialysis for 22 years. An abnormal small mass was found in one of the left renal cystic lesions by screening ultrasonography and CT scan at the 19th year of the hemodialysis. Left radical nephrectomy was performed and the histological diagnosis was a renal cell carcinoma (RCC). There was no evidence of recurrence and metastasis, however, he presented with asymptomatic macrohematuria two years after the operation. CT scan demonstrated the rapidly progressing right renal tumor and multiple para-aortic lymph node swelling. Right nephrectomy and lymphadenectomy were performed and pathological examination showed the advanced RCC with multiple lymph node metastasis. Eleven months after the second operation followed by interferon therapy. he died of multiorgan metastasis of the RCC. This is the first bilateral RCC case in polycystic kidney patient treated with hemodialysis in Japan.     

Intramural Hematoma of the Cecum as the Lead Point of Intussusception in an Elderly Patient with Hemophilia A: Report of a Case

Hemophilia A is a congenital bleeding disorder characterized by a deficiency of coagulation factor VIII. Intramural hematoma of the colon is a very rare complication of this disease. We report a case of intramural hematoma of the cecum serving as the lead point of intussusception in a 65-year-old man with hemophilia A. The patient presented with right-sided abdominal pain and bloody stool. Palpation of his abdomen revealed a fist-sized mass. Abdominal computed tomography (CT) showed a circular mass with concentric rings, consistent with an intussuscepted intestine. Because his activated partial thromboplastin time (APTT) was prolonged, we gave him a continuous infusion of factor VIII during and after surgery. Laparotomy revealed an irreducible colo-colic intussusception and we identified a cecal hematoma as the lead point. After an unsuccessful attempt at Hutchinson's maneuver, we performed right colectomy. We report this case to illustrate the necessity of monitoring APTT in patients with hemophilia A who undergo surgery.     

Adult jejunojejunal intussusception caused by metastasized pleomorphic carcinoma of the lung: Report of a case

Adult small-intestinal intussusception is rare and very different from childhood intussusception. Both benign and malignant pathologies can underlie small intestinal intussusception in adults, but malignancy is much less frequent. We report a case of jejunojejunal intussusception caused by an intestinal metastasis of the sarcomatoid component of pleomorphic carcinoma of the right lung. The patient, a 61-year-old man, underwent successful segmental jejunal resection. Adult small bowel intussusception, though an unusual cause of acute abdomen, requires early diagnosis and timely management. To our knowledge, this is the first report of adult jejunojejunal double intussusception caused by metastatic sarcomatoid carcinoma of the lung.     

Appendiceal intussusception to the cecum caused by mucocele of the appendix: Laparoscopic approach

INTRODUCTIONAppendiceal intussusception is a very rare disease that is found in only 0.01% of patients who have undergone an appendectomy. Clinical symptoms vary and some patients are asymptomatic. Laparoscopic surgery for appendiceal tumors is still controversial. We present a case of intussusception of the appendix with a mucinous cystadenoma treated by laparoscopic surgery.PRESENTATION OF CASEWe report a case of 47 year-old-women patient who presented with a six month history of intermittent right lower abdominal pain. Abdominal computer tomography CT showed appendiceal mass with intussusception. A laparoscopic right hemicolectomy was performed because the tumor involved the entire appendix. Histopathological examination revealed mucocele due to mucinous cystadenoma of appendix.DISCUSSIONAppendiceal intussusception to the cecum caused by mucocele of the appendix is extremely rare. It is very difficult to diagnose the presence of an intussuscepted appendix pre-operatively and investigations will usually include colonoscopy and CT scan. An appendicular intussusception should not be reduced by colonoscopy. Laparoscopic surgery for appendiceal tumors is still controversial; the main concerns to be addressed are the adequacy of resection and intraperitoneal rupture of the tumor. Our patient successfully underwent laparoscopic surgery without any complications.CONCLUSIONAppendiceal intussusception to the cecum caused by mucocele of the appendix is a rare cause of abdominal pain and difficult to diagnose. The laparoscopic surgery for appendiceal tumors is safe, feasible, and even may be beneficial.     

Gangrenous appendicitis in a child with Henoch-Schonlein purpura

Abdominal pain is common feature of Henoch-Schonlein purpura, which may mimic appendicitis, leading to unnecessary laparotomy. Accordingly, the diagnosis must be confirmed by ultrasonography or computed tomography scan before laparotomy is performed. The authors report a case of simultaneous occurrence of Henoch-Schonlein Purpura and gangrenous appendicitis in an 18 year-old boy. The patient was admitted with abdominal pain, cramps, and mild dehydration. He also complained of small reddish purple on his lower limbs, bilateral knee pain, low-grade fever, as well as bloody stools. The symptoms subsided completely. Eight days later, he returned with nonbloody, nonbilious emesis, abdominal cramps, and right lower quadrant abdominal tenderness. Abdominal ultrasound evaluation was performed to rule out an intussusception but demonstrated appendiceal dilatation with a possible appendicolith without any evidence of intussusception. A laparotomy was undertaken, and appendectomy was performed for gangrenous appendicitis. Simultaneous occurrence of Henoch-Schonlein purpura and acute appendicitis is rarely observed. Clinical features of the patients may mislead the clinicians, resulting in delayed diagnosis or misdiagnosis. The use of ultrasonography and computed tomography scan would confirm the diagnosis before surgery.     

Ileocolic Intussusception Caused by a Giant Ulcerating Lipoma of Bauhin’s Valve: an Unusual Cause of Intestinal Obstruction in the Adult

We report a case of intestinal obstruction in a 73-year-old woman caused by ileocolic intussusception. The underlying cause was a giant submucosal ulcerating lipoma (6?×?3.3?×?3.8 cm) extending from the superior mucosal lip of Bauhin’s valve. Abdominal ultrasonography showed a pathognomonic target-like mass appearing as multiple concentric rings. CT scan confirmed the diagnosis. Because of apparent obstruction, a laparotomy with right hemicolectomy and ileocolic anastomosis was performed. Lipomas most frequently occur in the cecum and ascending colon where they represent the most common submucosal mesenchymal tumor. They typically occur in elderly women with an incidence that varies from 0.15 to 0.56 %. Pain, rectal bleeding, and obstruction are typical symptoms. When faced with an intussusception in children, reduction with air per rectum can be performed. In adults, however, malignant cell spreading and seeding is of big concern. Since approximately 20–50 % of all underlying causes are malignant, explorative surgery is favored in adults.     

Intussusception secondary to endometriosis of the cecum

INTRODUCTION

Intussusception in adults is a rare cause of bowel obstruction. Endometriosis of the bowel is also a rare entity that can be the cause of bowel obstruction. Here, we report a rare case of intussusception secondary to endometriosis of the cecum.

PRESENTATION OF CASE

A 40-year-old woman presented to the hospital with a one-week history of intermittent epigastric pain. On physical examination, there was a soft, round non-tender palpable mass in the right flank and abdominal computed tomography scan revealed an intussusception. We made the diagnosis of ileo-colic intussusception and performed ileocecal resection. The surgical specimen revealed a round submucosal cystic mass in the cecum and the histology showed endometriosis of the cecum.

DISCUSSION

Intussusception in adults is a rare entity present in just 1% of all patients with bowel obstruction, and 5% of all intussusceptions. In general, intussusception in adults has a pathologic lesion as the lead point and the lesion is a malignancy in 20–50% of the cases. Thus, the treatment of an intussusception in adults should be operative. Endometriosis of the bowel is a rare cause of intussusception. Small endometriosis lesions of the bowel are unlikely to cause symptoms; however, in patients presenting with bowel obstruction, urgent treatment is indicated.

CONCLUSION

Intussusception in an adult is a rare cause of bowel obstruction and intussusception caused by endometriosis is also rare. Although rare, the diagnosis of endometriosis as a cause of intussusception must be considered as part of the differential diagnosis.     

Extraskeletal mesenchymal chondrosarcoma of the kidney

A 61-year-old woman was referred for evaluation of an incidental mass found on the right kidney. Abdominal ultrasonography and computed tomography showed a 3-cm tumor with calcification and peripheral enhancement. Under the diagnosis of renal cell carcinoma, a transabdominal right radical nephrectomy was performed. The pathological diagnosis was extraskeletal mesenchymal chondrosarcoma of the kidney. No recurrence or metastasis occurred during a 6-year follow up. Primary renal chondrosarcoma is extremely rare, this being only the fifth case reported in the English literature, and the patient's extended survival is attributed to the small size of the tumor, as well as early diagnosis and treatment.     

Carcinoma Cecum Presenting as Right Gluteal Abscess Through Inferior Lumbar Triangle Pathway—Report of a Rare Case

Gluteal abscess commonly follows intramuscular injections with contaminated needles. Carcinoma cecum is known to present with pericolic abscess due to microperforations and may rupture intraperitoneally. Gluteal abscess secondary to perforated carcinoma cecum with pericolic abscess is extremely uncommon. A 50-year-old woman who was receiving intramuscular iron injections for anemia presented with a 10 × 10-cm abscess in the right gluteal region and a vague mass in the right iliac fossa. After investigations, a diagnosis of perforated carcinoma cecum with pericolic abscess tracking into the right gluteal region was made, and incision and drainage were done. Fine-needle aspiration cytology from the cecal growth revealed adenocarcinoma. Unfortunately, the patient was not willing to undergo definitive treatment. This case is being reported for its rarity and as an uncommon etiology for a common condition.Key words: Gluteal abscess, Carcinoma cecum, Inferior lumbar triangleGluteal abscess is a common condition and most commonly follows intramuscular injections with contaminated needles.^1,2 Carcinoma cecum is known to present with pericolic abscess due to microperforations and may rupture intraperitoneally. Retroperitoneal abscess is rare with carcinoma cecum. Gluteal abscess secondary to perforated carcinoma cecum with pericolic abscess is extremely uncommon. Here we report a case of carcinoma cecum presenting as right gluteal abscess for its rarity and diagnostic challenge and to review its pathogenesis.     

Intussusception in adults

The authors report eight cases of intussusception of small and large intestine in adults during five years. 3 of the intussusception caused by simple tumors in five cases by malignant. In three cases were chronic presented long term signs and symptoms. Ileo-ileal invagination was diagnostised at 3 patients, ileo-caecal in one case and ileocolic intussusception also in one case. In 2 cases developed caeco-colic, in one case colo-colic invagination. Resection was strongly indicated in seven cases and wedge resection was done at the last patient. One patient has died of cerebral multiple embilization. They review the etiology and pathology, the signs and symptoms as well as the difficulties during diagnosis and treatment of the intussusceptions according to their own experience and literary datas. The authors draw the attention to the importance of the modern iconographic, tools, particularly the ultrasonography in the diagnosis of intussusception.     

Combined small cell carcinoma and sarcomatoid squamous cell carcinoma in the renal pelvis

We report here a case of combined small cell carcinoma and sarcomatoid squamous cell carcinoma in the renal pelvis. A 61-year-old female presented with right flank discomfort, microhematuria and progressive renal dysfunction. Following diagnosis of right renal pelvic carcinoma, radical nephroureterectomy with lymph node dissection was performed through a midline incision. The tumor was pathologically diagnosed to be combined small cell carcinoma and sarcomatoid squamous cell carcinoma in the renal pelvis. The patient had no evidence of recurrence or metastasis, 16 months postoperatively. Small cell carcinoma or sarcomatoid squamous cell carcinoma of the renal pelvis is very rare. We believe this is the first such case to be reported in the world.     

Burkitt's lymphoma revealed by acute intussusception in children]

STUDY AIM: Burkitt's lymphomas are rarely revealed by acute intestinal intussusception in children. The study aim was to report eight cases. PATIENTS AND METHODS: Between 1988 and 1999, eight children, seven boys and one girl (mean age: 6 years) were hospitalized for an acute abdominal syndrome. Abdominal ultrasonography showed intestinal intussusception (n = 8) primitive tumor (n = 2), mesentivic lymph nodes (n = 2) and liver nodes (n = 1). Enema (n = 6) confirmed presence and irreductibility of the intestinal intussusception. A laparotomy was performed on emergency in seven patients and found the primitive tumor in 6. The procedure consisted in disinvagination (n = 4) and intestinal resection for ischaemia (n = 2). One patient was not operated on and the diagnosis was performed through ultrasonography guided tumoral puncture. RESULTS: According to the Murphy classification, there were 2 stage II, 3 stage III and 3 stage IV patients. With LMB protocol chemotherapy, a complete remission was observed following the first cure. All the children were alive at the time of this study with a follow-up longer than one year after the complete remission. CONCLUSION: Abdominal sonography is the most efficient examination for the diagnosis of intestinal intussusception and sometimes of the primitive lesion. In the absence of sonographic intestinal impair, thanks to ultrasonography guided tumoral puncture, diagnosis may be made and chemotherapy started. If the lymphoma is not visualized with ultrasonography, an emergency laparotomy is necessary for the diagnosis of the lymphoma and the intestinal resection in case of necessity. Burkitt's lymphoma is very sensible to chemotherapy.     

Collecting duct carcinoma with acquired cystic disease of the kidney in a long-term hemodialysis patient

Abstract:   We report a very rare case of collecting or Bellini duct carcinoma (CDC) found in a 60-year-old male who had received hemodialysis therapy for 21 years. Screening with ultrasonography revealed a solid tumor originating from the cyst wall in the right kidney with acquired cystic disease of the kidney. Subsequent computed tomography (CT) and angiography could not detect another renal tumor. Right radical nephrectomy was performed. The tumor detected preoperatively was composed of papillary renal cell tumor (RCC) and multiple clear cell carcinoma, pathologically. In addition to the tumors, CDC was revealed in the central medulla with the involvement of regional lymph nodes. Three months later, left nephrectomy was performed because left RCC was suspected during CT. The histological diagnosis was multiple clear cell carcinomas. Peritonitis carcinomatosa appeared and the patient died 13 months later.
