Ovarian teratoma presenting as small bowel obstruction in an elderly lady-A case report

Teratomas of the ovary are of the mature or immature type. The mature variety is called dermoid cysts, which is the most frequent benign germ cell tumour of the ovary in the reproductive age group. They are usually asymptomatic until they reach a significant dimension.(1) Pressure effect, torsion and rupture of an ovarian cyst may present as an acute abdomen. A case is presented where an elderly lady presented with small bowel obstruction due to a very large, non-adherent to the intestine, dermoid cyst.     

Primary retroperitoneal mature cystic teratoma in an adult: A case report

BackgroundMature cystic teratoma is one of the most common tumors of the ovaries; however, primary retroperitoneal lesions are rare entities in adults.Case summaryWe report a case of a 33 year-old woman noticing a mass in her epigastric and left upper abdominal region without any specific signs and symptoms. Radiological evaluation revealed a retroperitoneal mass with extension from the posterior aspect of the pancreas to the pelvic cavity, composed of calcifications and cystic elements.ConclusionThe tumor was resected through a midline laparotomy and the pathology report confirmed the diagnosis of a mature cystic teratoma with no evidence of malignancy or immature components.     

Dermoid cyst in the Hepatoduodenal ligament: Report of a case

We report an unusual case of a mature cystic teratoma, or dermoid cyst, in the hepatoduodenal ligament of a young woman. Mature cystic teratomas are rarely found in extragonadal sites, especially the hepatoduodenal ligament. Surgical resection remains the mainstay of therapy and is required for a definitive diagnosis. Patients who undergo complete resection of a mature cystic teratoma normally have an excellent prognosis.     

Uterine leiomyoma causing menometrorrhagia with a concomitant mature teratoma in a 15-year-old child: a case report and review of the literature

Uterine leiomyoma is the most common uterine tumor in adult females but is rare in the pediatric population with only 10 previous cases reported. We describe the unique case of a 15-year-old girl who presented with abdominal pain and menometrorrhagia and was found to have a uterine leiomyoma as well as a mature ovarian teratoma that required surgical resection. We review diagnostic imaging and optimal management for the 2 gynecologic masses in this teenage girl.     

Epidermoid cyst of the spleen,a case report

IntroductionSplenic tumors are rare and are either primary or secondary, benign or malignant. Most have none to minimal symptomatology and are found incidentally. Splenic cysts can be infectious, congenital, or traumatic. Epidermoid cysts and parasitic cysts are examples of primary cysts and usually have a classic presentation on imaging. Despite advanced imaging modalities and patient's clinical presentation, it can be difficult to diagnose an epidermoid cyst without histological examination. The purpose of this paper is to discuss typical findings of primary splenic cysts on imaging, but how they may differ in appearance.Presentation of case51 year old female who presented with vague abdominal discomfort and was found to have a large splenic mass with cystic components on imaging which did not demonstrate a typical primary splenic cyst appearance. Patient underwent an uneventful hand-assisted laparoscopic total splenectomy and had an uneventful recovery with histopathology revealing an epidermoid splenic cyst.ConclusionPrimary splenic cysts are difficult to diagnose and differentiate with imaging alone. They have a variable presentation and can present like as a cystic mass. It is important to include them in the differential diagnosis of splenic masses since histopathology is the final determinant of the diagnosis.     

Peliosis lienalis with atraumatic splenic rupture in a patient with chronic myelomonocytic leukemia: A case report

IntroductionAtraumatic splenic rupture is a rare but life-threatening condition which may be associated with hematological malignancies.Presentation of caseWe present the case of a 63-year-old male patient with a history of chronic myelomonocytic leukemia and sarcoidosis under therapy with prednisone, who suffered an atraumatic splenic rupture with hemodynamic instability. He was managed with proximal splenic artery embolization and secondary open splenectomy. On pathology the diagnosis of peliosis lienalis was established.DiscussionPeliosis is a rare pathological entity, which presents with multiple blood-filled cavities within parenchymatous organs and is of unknown etiology and pathogenesis. In retrospect a rapid increase in splenomegaly and inhomogeneous parenchyma of the spleen on sonography was realized.ConclusionSonographic changes in size and parenchyma of the spleen in patients with hematological malignancies might help suspecting peliosis lienalis with impending splenic rupture and could alter clinical management towards a prophylactic splenectomy.     

Congenital sublingual teratoid cyst: a case report and literature review

Head and neck dermoid cysts comprise less than 10% of all dermoid cysts. The sublingual location is very rare. One hypothesis for their etiology is that they arise from entrapment of epithelial debris or rests during the midline fusion of the first 2 branchial arches. They are classified as epidermoid, dermoid, and teratoid cysts. Sublingual cysts are slow-growing lesions generally seen in the second and third decades of life. They are rare in childhood. The cysts may interfere with swallowing and breathing. Rarely, they may show malignant transformation. Surgical extirpation is the treatment of choice.     

Primary malignant teratoma of the kidney: a rare case report and literature review

Teratomas originate from pluripotent cells and can differentiate along one or more embryonic germ lines. Renal teratoma is infrequent and malignant renal teratoma is even rarer. Experience in the diagnosis and treatment of this uncommon malignancy is seriously limited. In this report, we described the case of a 64-year-old female who complained of right flank pain for 4 months. Computed tomography (CT) revealed a hypodense mass (50 mm in maximum diameter) with slow contrast enhancement and obscure boundary located in the lower pole of the right kidney. CT also showed multiple retroperitoneal lymphadenectasis. Retroperitoneal laparoscopic right radical nephrectomy along with regional lymphadenectomy was successfully performed, and postoperative pathological examination confirmed malignant teratoma of the kidney. After surgery, the patient received adjuvant chemotherapy with BEP (bleomycin, etoposide, and cisplatin) protocol. At the 6-month follow-up, pulmonary and liver metastases were discovered by CT and the patient refused any further treatment. Unfortunately, she died at 16 months postoperatively. Although primary renal malignant teratoma is extremely rare, this kind of tumor should be taken into consideration. Currently, there is no therapeutic standard consensus for this disease and the prognosis remains unclear. Early detection and surgical intervention is critical, and more research on postoperative adjuvant therapy should be performed.     

A splenic cyst causing a viscerosomatic reflex in the thoracic spine. A case report

IntroductionMusculoskeletal pain in the thoracic spine is a common complaint and often seen in the osteopathic clinic. An underlying cause may be pain originating from an internal organ referring to the segmental related somatic structures, i.e. a viscerosomatic reflex. A splenic cyst causing a viscerosomatic reflex in the thoracic spine is a rare but serious differential diagnosis for thoracic musculoskeletal pain that may be identified during routine osteopathic assessment and treatment.Case presentationA 36-year-old women was referred for osteopathy with pain in the thoracic spine as the main complaint. The pain was aggravated by twisting motions, prolonged standing and sitting. The physical examination identified hyperalgesia, hypertonic paraspinal muscles with trophic changes at T6-10 and hypomobility at T6-8. On palpation the diaphragm muscle was hypertonic. In the abdomen, a palpable mass was found in the left upper quadrant, which was suspected to be an enlarged spleen. A normal size spleen is not palpable; therefore, the patient was referred for further investigations. An X-ray and CT scan identified a splenic cyst of approximately 10 cm which was removed with a splenectomy as advised, leading to resolution of the thoracic pain.ConclusionA splenic cyst mimicking mechanical pain in the thoracic spine is rare; however, this case report highlights the importance of comprehensive history taking and screening of red flags, combined with careful physical examination of both musculoskeletal and visceral structures.     

Mature teratoma arising from an intraabdominal testis in a 2-month-old boy: case report and review of intraabdominal testicular tumors in children

Tumors arising in an undescended testis are rare in infants. We report a mature teratoma in an intraabdominal testis of a 2-month-old boy. He presented with a large left-sided abdominal mass and nonpalpable left testis. Abdominal ultrasound and computed tomography showed a well-defined, sizable cystic tumor with focal calcification in the lower abdomen. Tumor markers were all within normal limits. Surgical resection revealed a large tumor arising from an intraabdominal left testis, and histologic analysis identified a mature teratoma. The tumor was completely removed, and there was no recurrence at follow-up 3 years later. The histologic condition of prepubertal intraabdominal testicular (IAT) tumors is quite different from that of testicular tumors in childhood descended testes and postpubertal IAT tumors. A total of 30 cases of IAT tumors in children, including our case, were reviewed to elucidate this issue.     

Splenic hamartoma associated with thrombocytopenia: A case report

IntroductionHamartomas are rare, benign tumors of the spleen. Few cases of splenic hamartomas associated with thrombocytopenia have been reported.Presentation of caseAn asymptomatic 64-year-old man with myelodysplastic syndrome was found to have a splenic tumor. Laboratory tests were significant for thrombocytopenia, with a platelet count of 7.8 × 10⁴/μL. Ultrasonography showed splenomegaly (10.8 × 6.6 cm), and a hypoechoic splenic mass (8.0 × 7.0 cm). Color doppler ultrasound revealed blood flow within the mass, and the mass density was homogeneous on abdominal computed tomography (CT). Contrast-enhanced CT showed heterogeneous enhancement of the splenic mass during the arterial phase. Positron emission tomography (PET)-CT showed no significant fludeoxyglucose (FDG) accumulation within the mass. The differential diagnosis included splenic hamartoma, splenic hemangioma, splenomegaly associated with extramedullary hematopoiesis, and malignant tumor, including solitary splenic metastasis. A laparoscopic splenectomy was performed due to the possibility of malignancy, the presence of thrombocytopenia, and the risk of splenic rupture. The resected specimen showed a localized, well-demarcated, 8.0 × 7.0 cm splenic mass. Histological examination revealed abnormal red pulp proliferation and the absence of normal splenic structures. The patient’s post-operative course was uneventful. His platelet count improved on post-operative day 1 and he was discharged on post-operative day 9. He remained in good health with a normal platelet count one month after surgery.DiscussionMaking definitive preoperative diagnosis is difficult in splenic hamartomas. Surgery is necessary for diagnosis when malignancy cannot be ruled out.ConclusionsSurgery may also improve symptoms of hypersplenism, including thrombocytopenia.     

Laparoscopic partial splenectomy for congenital splenic cyst in a pediatric patient: Case report and review of literature

Non-parasitic splenic cysts (NPSC) are a rare condition that makes difficult to know their true incidence and represent 10% of all benign splenic cysts, they can be either congenital with the presence of epithelial lining that originate from invagination of the capsular mesothelial lining or post-traumatic with absence of epithelial lining. We present our management of a splenic congenital cyst in a pediatric patient. A 10-year-old female patient presented to the clinic complaining with a 3-week abdominal pain at the left upper quadrant. An ultrasound showed an enlarged spleen with a thinned walled cystic image on the lower pole of 5 cm. An abdominal CT confirmed the presence of a splenic cyst at the lower pole of the spleen of 5 cm in diameter. Three-port laparoscopic partial splenectomy was done isolating and dividing the lower splenic artery and vein and the lower pole of the spleen with a vessel sealing device. Management of a non-parasitic splenic cyst is controversial: cystectomy, fenestration, percutaneous drainage and sclerotherapy have been previously described, most of them aiming to preserve spleen function and avoiding overwhelming post-splenectomy infection. Partial splenectomy seems the most effective one in terms of preserving spleen function and avoiding recurrence.     

Massive left hemothorax following left diaphragmatic and splenic rupture with visceral herniation: A case report

BackgroundMassive left hemothorax following left diaphragmatic and splenic rupture with visceral herniation is quite an uncommon life-threatening condition usually associated with blunt thoracoabdominal trauma. Mortality is generally associated with coexistent vascular and visceral injuries that could be rapidly fatal. Timely, and proper diagnosis is mandatory as survival depends on prompt diagnosis and treatment.Presentation of caseWe describe a case of massive left hemothorax secondary to blunt thoracoabdominal injury with left diaphragmatic and splenic rupture, gastric, greater omentum and splenic herniation into the left thoracic cavity in a 32 years old male car driver after sustaining a road traffic accident and presented with shortness of breath of 4 h’ duration. He also had zone 3 retroperitoneal hematoma and left acetabular fracture. He was treated surgically and discharged home improved.DiscussionDiaphragmatic ruptures following blunt injuries are larger leading to herniation of visceral organs into the thoracic cavity and the most common organ to herniate on the left side is the stomach followed by omentum and small intestine. Splenic rupture is a very rare cause of hemothorax and is often missed in the differential diagnosis.ConclusionMassive hemothorax following splenic and diaphragmatic rupture with visceral herniation following either blunt or penetrating trauma is rare. Delayed or missed diagnosis is associated with higher morbidity and mortality. A high index of suspicion and proper use of diagnostic studies are crucial for early and correct diagnosis.     

Non-traumatic rupture of voluminous non-typhoid Salmonella splenic abscess presenting with peritonitis: Case report and review of the literature

Introduction and importanceSplenic abscess (SA) is an uncommon, life-threatening disease with about 600 reported cases in the literature. It is caused by various infective pathogens and generally occurs in immunocompromised patients. SA is a rare complication of non-typhoid Salmonella (NTS) infection. Diagnosis of ruptured SA is a challenge because the absence of specific symptoms and signs. Abdominal computed tomography (CT) scan represents the gold standard in diagnosing of SA. Splenectomy is the treatment of choice of ruptured SA with peritonitis.Case presentationA 26-year-old Caucasian female was admitted to the Emergency Department with a three-day history of abdominal pain and fever. Physical examination revealed severe and generalized abdominal pain on superficial and deep palpation with obvious muscle guarding and rebound tenderness. Abdominal CT scan showed ruptured SA. Laboratory tests reported anemia (hemoglobin 10.4 g/dl). The patient was taken emergently to the operating room for splenectomy. The postoperative course was uneventful, the patient was discharged on the 7th post-operative day. Diagnosis of NTS SA was made by pus cultures.Clinical discussionSA is a rare complication of NTS infection associated with high morbidity and mortality rates. Although different types of treatment of SA are reported in the literature, splenectomy represents the treatment of choice of ruptured SA.ConclusionNTS SA is difficult to diagnose because of its rarity and non-specific clinical presentation, often fatal if left untreated. Although there is no gold standard for treating SA, splenectomy with peritoneal lavage is mandatory in case of ruptured SA with peritonitis.     

Image-diagnostic features of mature cystic teratomas of the pancreas: report on two cases difficult to diagnose preoperatively

This report documents the findings of two rare cases of mature cystic teratoma of the pancreas. Although they could not be diagnosed preoperatively, our retrospective report suggests that the combined diagnosis of ultrasonography (US), enhanced computed tomography (CT), and magnetic resonance cholangiopancreatography (MRCP) might allow differentiation from other cystic lesions such as mucinous cystic tumors (MCTs) and intraductal papillary–mucinous tumors (IPMTs). Since the cystic teratomas were both filled with keratinous and sebaceous material, they were echogenic, appearing as solid masses on US. Enhanced CT showed their cystic nature, with values slightly higher than water, and MRCP revealed defects of internal signals.     

Conservative laparoscopic treatment of a posttraumatic splenic cyst

Laparoscopy has recently been demonstrated to be a useful alternative to open surgery for the surgical treatment of spleen disorders, and it can also facilitate a conservative approach for treatment of selected spleen lesions. We present the laparoscopic spleen-preserving treatment of a post-traumatic spleen cyst. A 28-year-old female presented a mass in the left hypochondrium immediately after an uneventful pregnancy. CT revealed a splenic cyst of 10×8 cm. Laparoscopic exploration showed a cyst located in the lower pole of the spleen. All the cyst wall not covered by spleen tissue (70%) was excised, and the fragment of cyst wall was recovered through a bag. The patient recovered uneventfully and was discharged 72 hours later. The laparoscopic approach should be considered for evaluation and treatment of selected benign cystic lesions of liver, retroperitoneum or spleen origin.
