Carcinosarcomas are rare, malignant, biphasic tumors. We report the case of a 62-year-old man with gastric carcinosarcoma, along with its clinical, macroscopic and histopathological features. Macroscopically, a specimen of deformed stomach was obtained that measured 200 mm x 150 mm x 100 mm. A 150 mm x 100 mm x 50 mm exophytic tumoral mass (Borrmann type I) was found, which involved the posterior wall from the cardia to the antrum. Histopathologically, a mixed type of malignancy was revealed: an adenocarcinoma with intestinal metaplasia, with interposed fascicles of fusiform atypical cells and numerous large, rounded and oval cells. The tumor showed positive histochemistry for cytokeratin 18, epithelial membrane antigen, carcinoembryonic antigen, chromogranin A and vimentin. Liver metastases were diagnosed 8 mo postoperatively, and the patient died 4 mo later. A review of the available literature is also presented.

The preservation of the ICBN significantly improved the functional effect of the axillary dissection for breast cancer by reducing sensory loss, while there was no difference in pain intensity and duration. Although we did not prove that the preservation of LTV prevents breast edema after conservative surgery for breast cancer, we think that more complex analysis, including parameters such as the extent of resection of breast tissue, the dimension and constitutional characteristics of the breast, tumor location, obesity, and further developments in surgical technique, would reveal at least discrete improvements in the functional results of this surgical approach.

Primary non-Hodgkins lymphoma of the uterine cervix is a very rare diagnosis. A 54-year-old woman presented with a 3-month history of postmenopausal bleeding per vaginum. On examination, a friable, fungating lesion was seen on the cervix. Histology revealed a CD 20 positive high-grade non-Hodgkin's diffuse large B cell lymphoma from cervical biopsies and endometrial curettage. She was diagnosed as stage IE after workup and subsequently treated with six cycles of R-CHOP chemotherapy followed by radiotherapy of the involved field.

Authors analysed 15 cases with visceral metastasis of melanoma. In eight cases the primary was unknown but in seven cases the data about primary was known. From 15 patients 10 were male and 5 female. All metastases were in abdominal cavity (liver-3, abdominal lymph nodes-4. stomach-2, bowel-4, omentum-1, spleen-1, oesophagus-1, adrenal-2 cases. In one case metastatic deposit was in brain and in one case i the vertebral body. In 6 cases visceral metastases were in more than one location.

Composite glandular/exocrine-endocrine carcinoma of the gastrointestinal tract is a special tumor type composed of common adenocarcinoma and the neuroendocrine component comprising at least one-third of the whole tumor area. These tumors are rare in the stomach and mostly published as case reports. We describe a further case of a 36-year-old man being unique in that it was associated with extensive formation of sarcoid-like granulomas. Tumor consisted of, predominantly poorly differentiated, intestinal-type adenocarcinoma and poorly differentiated neuroendocrine, small cell carcinoma. The adenocarcinomatous and neuroendocrine areas were separated, but closely juxtaposed with focal areas showing gradual transition from one to another. Perigastric lymph node metastases corresponded either to neuroendocrine or adenocarcinomatous component. On immunohistochemistry, the exocrine part was positive for cytokeratin 7, whereas superficial well-differentiated parts showed positivity with cytokeratin 20 as well. The neuroendocrine component was negative with those two types of cytokeratin. Both adenocarcinomatous and neuroendocrine tumor portions showed carcinoembryonic antigen (CEA) immunoexpression. Neuroendocrine markers (chromogranin A, synaptophysin and neuron-specific enolase) were diffusely positive in the neuroendocrine component, and found only in the scattered cells within the neoplastic glands of the adenocarcinoma. Entire gastric mucosa and all perigastric lymph nodes were extensively affected by noncaseating, sarcoid-like granulomas. The absence of any clinical manifestations combined with the negative results of chest radiograph and laboratory test for the serum angiotensin converting enzyme argued against the possibility of systemic sarcoidosis.
