Sarcomatoid Carcinoma of the Ureter: A Case Report 总被引:1,自引:0,他引:1

We report a case of sarcomatoid carcinoma of the ureter in a 60-year-old woman who presented at our hospital with right flank pain. She had undergone total ovariectomy and radiation therapy for ovarian cancer at the age of 40 years. A diagnosis of ureteral tumor (cTsNOMO) led to radical right nephroure-terectomy and partial cystectomy. Microscopic examination showed a tumor that contained areas of both sarcoma and transitional cell carcinoma. The carcinomatous tissues were blended into the sarcomatous areas and there was a transitional zone between the 2 components. Immunohistochemical examination showed that the spindle cells were positive for cytokeratin, so the final diagnosis was sarcomatoid carcinoma of the ureter. The patient has remained well without any evidence of recurrence for 5 months since the operation. There is no effective adjunctive therapy, so constant careful monitoring will be necessary. Sarcomatoid carcinoma of the ureter is a rare tumor and this is only the sixth case reported in Japan. 相似文献

A case of small cell carcinoma of the prostate without a primary lesion in the lung was reported. The cancer was diagnosed after the patient complained of lumbago caused by bone metastasis. The tumor was 5.9 times 5.0 times 4.6cm. The patient was treated with 4 courses of chemotherapy using cisplatin and etoposide. The tumor diminished to 4.0 times 4.0 times 3.5 cm after completion of the 4 courses of treatment. Prostatic antigen levels were less than 1.0ng/mL during the therapy. Neuron-specific enolase levels were 35.9ng/mL at the beginning of therapy, and decreased to 7.4 ng/mL after completion of 4 courses of treatment. The patient died 3 months after the completion of treatment. This regimen had some value for inhibiting the growth of small cell carcinoma. 相似文献

Renal cell carcinoma (RCC) may metastasize to almost any organ, but it is unlikely to be a direct cause of intussusception.
We report a case of double enteric intussusceptions caused by metastatic RCC in a 64-year-old man. The patient presented with
intermittent abdominal pain and diarrhea 11 years after undergoing a radical nephrectomy. Abdominal computed tomography (CT)
showed two enhanced masses with the “target” sign, suggesting enteric intussusceptions. We performed partial enterectomy,
and histological examination confirmed that the tumors had originated from RCC. To our knowledge, this is the first report
of metastases from RCC manifesting as synchronous intraluminal polypoid tumors serving as the lead points of two intussusceptions
in the small intestine. Thus, the possibility of multiple tumor metastases in the small intestine, with or without intussusceptions,
should be considered in patients with recurrent RCC. 相似文献

Plexiform schwannoma is a benign peripheral nerve sheath tumor composed exclusively of schwann cells arranged in a plexiform pattern. Most plexiform schwannomas are skin tumors and there has been only one case report of this tumor originating in the colon. We describe herein the first known case of plexiform schwannoma of the small intestine occurring without any relationship to schwannomatosis or neurofibromatosis. A 57-year-old man presented with a short history of abdominal pain, vomiting, and bloody stool after each meal. Jejunography demonstrated multiple nodular tumors in the small intestine. We resected the small intestine laparoscopically. The tumors consisted of multiple white nodules in the submucosal and subserosal layers. Microscopic examination revealed that each tumor was composed mainly of Antony A tissue, compatible with conventional schwannoma. Immunohistochemically, the tumors were positive for S-100, vimentin, and neuron-specific enolase, and negative for HHF35, -SMA, and c-kit. No evidence of recurrence has been found in 38 months of follow-up. 相似文献

The small intestine is the most common site of gastro-intestinal metastasis from cutaneous malignant melanoma. A primary origin at this site has been reported in rare cases. We report a case of a 71-year-old man with a primary malignant melanoma in the jejunum. The patient presented with weakness, weight loss, non-specific abdominal pain and episodes of fainting. After clinical examination, laboratory evaluation and radiological work-up, which included CT of the abdomen, the patient was diagnosed with a tumour mass in the jejunum. This diagnosis was confirmed at laparotomy. The patient underwent enterectomy with wide excision of the tumour. A primary malignant melanoma of the small intestine is an extremely rare neoplasm.A definite diagnosis can only be made after a thorough investigation has been made to exclude the co-existence of a primary lesion elsewhere. Curative resection of the tumour remains the treatment of choice. 相似文献

Small Cell Carcinoma of the Kidney: Case Report 总被引:1,自引:0,他引:1

An 83-year-old female diagnosed with small cell carcinoma of the kidney is reported on. The clinical picture was similar to that seen with transitional cell carcinoma of the renal pelvis. A right nephroureterectomy was performed and a histological examination revealed similar morphological features to those of small cell carcinoma of the lung. Neuroendocrine differentiation was proven by a positive immunoreaction to neuron-specific enoiase. A review of the literature indicated that in the urinary tract, most of the cases of small cell carcinoma occurred in the urinary bladder, with this case being the eleventh reported case of small cell carcinoma originating in the kidney. As with many of the other cases of small cell carcinoma of the urinary tract, this patient's tumor was associated with both adenomatous and squamous differentiation. The patient died 2 months after surgery, prior to any chemotherapy administration. 相似文献

The small intestine is the most common site of gastrointestinal (GI) metastases from cutaneous malignant melanoma; however,
primary malignant melanoma originating in the small intestine is extremely rare. We report the case of a 72-year-old man found
to have a primary malignant melanoma in the ileum. The patient presented with anorexia, weight loss, diffuse colicky abdominal
pain, and episodic rectal bleeding. A preoperative diagnosis of a small intestinal tumor was based on the findings of enteroclysis
and computed tomography scanning. This diagnosis was confirmed at laparotomy and an enterectomy was performed. Histopathological
examination of the resected specimen clarified the exact nature of the lesion, confirming the diagnosis of melanoma. A thorough
postoperative investigation did not reveal a primary lesion in the skin, anus, oculus, or any other location. Thus, we diagnosed
this tumor as a primary lesion. One year after his operation, the patient remains well without any evidence of recurrence.
Primary malignant melanoma of the small intestine is an extremely rare lesion, which must be differentiated from other intestinal
tumors.
