Small bowel metastases from esophageal and oropharyngeal cancers.

Intestinal metastases are uncommon. Lungs and skin are the common sites of primary tumor. We report two men (52- and 67-year-old) with small bowel metastases from esophageal and oropharyngeal carcinomas.

Ileal Malignant Melanoma Presenting as a Mass with Aneurysmal Dilatation: A Case Report

Malignant melanoma is the most common metastatic tumor of the gastrointestinal tract and can present with fairly common constitutional symptoms. A 36-yr-old woman was found to have a secondary malignant melanoma in the terminal ileum with profuse aneurysmal dilatation, which is not the typical presentation of the malignant melanoma in the small intestine. Radiologic studies revealed a large tumor involving the distal ileum with aneurysmal dilatations having afferent and efferent loops, which needed to be differentiated from malignant lymphoma and other gastrointestinal tumors. Exploratory laparotomy was done, and we found a huge mass with plentiful aneurysmal dilatations; much the same of the findings from the previous studies. Segmental resection with the surrounding omentum was done followed by end-to-end anastomosis between both ends of the remaining ileum. She had been free from any evidence of the local or systemic recurrence for one year after the completion of eighteen months of the subcutaneous interferon treatment; postoperatively however, the occurrence of metastatic mass at the right axilla rendered us from complete resection due to severe penetration into the vital nerves and vessels in the axilla.

Ileal segmental gangrene caused by a metastatic mesenteric carcinoid

Malignant tumors of the small intestine are rare and their symptoms are discrete and of a chronic nature. At times they manifest as an acute abdomen, with high mortality. Carcinoid tumors represent one of the types of intestinal tumors, of the neuroendocrine line, more frequently located in the cecal appendix. In the small intestine, carcinoid tumors are most often located in the ileum. Carcinoid tumors produce several hormonal substances, some of which may induce symptoms such as the carcinoid syndrome. Gangrene of the small intestine is a rare complication attributed to hormonal substances produced by the tumor which causes high mortality rates. We report, here, a case of ileal segmental gangrene with an excellent course.

Casos clínicos hemi-hemipelvectomía

This is a 37 years old female with diagnosis of osteochondromatosis of the fibula: six months afterwardas develops left iliopubic destruction. The pathology reports chondrosarcoma, a hemipelvectomy is performed preserving the limb. No complications were present in the post- operative period; she started partial weigh bearing with cruches three months after surgery.

Metastase isolada de carcinoma espino-celular do esôfago no íleo terminal: relato de um caso / Isolated metastasis of squamous cell carcinoma of the esophagus in terminal ileum: report of a case

A propósito de um caso de carcinoma espin-celular do terço médio do esôfago, com metástase isolada no íleo terminal, operado no Hospital Escola da Faculdade de Medicina do ABC, é feita uma revisäo do assunto, assinalando a raridade do achado, pois apenas 18 casos foram relatos na literatura, sendo todos descritos em material de necropsias. No caso estudado, a revisäo minuciosa da cavidade abdominal após execuçäo de gastrotomia, mostrou lesäo neoplásica no íelo terminal, que foi ressecada. O exame histopatológico revelou o caráter metastático da lesäo. A partir deste achado, é enfatizada a importância de uma revisäo sistemática e minuciosa de toda a cavidade abdominal nos pacientes portadores de carcinoma espino-celular de esôfago
