Sarcomatoid carcinoma of the small intestine is an extremely rare malignant neoplasm that usually has a poor prognosis. We report a case of sarcomatoid carcinoma arising in the small intestine in a 62-year-old man who was hospitalized for abdominal pain. Computed tomography revealed wall thickening of the small intestine. The resected specimen showed a gray-whitish solid mass with hemorrhage an...

Sarcomatoid carcinoma is a rare biphasic tumor characterized by a combination of malignant epithelial and mesenchymal cells. We report a rare case of sarcomatoid carcinoma of the colon. A 41-yr-old woman was hospitalized with a history of melena. Total colectomy was performed under the impression of colonic carcinoma. Histologically, the tumor was composed of differentiated adenocarcinoma in su...

Sarcomatoid variant of anaplastic large cell lymphoma (ALCL) is an extremely rare variant of ALCL with an abnormal morphology and immunophenotype, which is easily misdiagnosed as a high-grade sarcoma, poorly differentiated cancer or melanoma. Here, we reported the case of a 7-year-old boy with a sarcomatoid variant of ALCL involving the right neck lymph node, and compared it with those of the r...

Renal cell carcinoma (RCC) is the most common malignancy of the kidney and has multiple subtypes. The sarcomatoid variety is considered a form of dedifferentiated carcinoma. It is more commonly associated with clear cell variant but very few are associated with chromophobe RCC. When present, it is associated with a significant decrease in patient survival due to its rapid growth and intrusive b...

We report chromophobe renal cell carcinoma (CRCC) with sarcomatoid dedifferentiation in a sixty-five year old male. CRCC is a prognostically better, distinctive subtype of renal cell carcinoma (RCC), histologically characterized by cells containing translucent and reticulated cytoplasm with distinct cell borders. Sarcomatoid component accompanies 9% of CRCC which alters its prognostic implicati...

BACKGROUND Lip metastases are rare clinical events that are frequently mistaken for other diagnoses. For sarcomatoid lung carcinoma, a rare histologic variant of non-small cell lung cancer, the incidence and pattern of cutaneous spread is poorly understood. CASE PRESENTATION We present a case of a 79-year-old African American man with a rapidly progressive upper lip cutaneous lesion that prov...

Sarcomatoid carcinoma of nasal cavity and paranasal sinuses is an extremely rare malignant neoplasm. We report a case of sarcomatoid carcinoma arising in the left-side nasal cavity and paranasal sinuses in a 65-year-old man who was hospitalized for left-side nasal epistaxis, odor sensation. Histopathologic examination revealed the tumor was composed of pleomorphic spindle and round cells with f...

In Brazil, without considering the non-melanoma skin tumors, bladder cancer in men is the eighth most common, and the urothelial carcinoma or transitional cell carcinoma is the most common among these. Cutaneous metastases from urothelial neoplasms appear as single or multiple erythematous, infiltrated nodules or plaques, and like other cases of distant disease, it is indicative of poor prognos...

Salivary duct carcinoma (SDC) is an uncommon, high-grade tumor. We present 8 cases of sarcomatoid SDC, which has been defined recently as a rare variant of SDC. The 8 patients (5 men, 3 women) had a mean age of 63.6 years. Histologically, all tumors were characterized by a biphasic neoplasm composed of both SDC and sarcomatoid elements. In 3 cases, sarcomatoid components showed osteosarcomatous...

BACKGROUND Selenite is a promising anticancer agent which has been shown to induce apoptosis in malignant mesothelioma cells in a phenotype-dependent manner, where cells of the chemoresistant sarcomatoid phenotype are more sensitive. METHODS In this paper, we investigate the apoptosis signalling mechanisms in sarcomatoid and epithelioid mesothelioma cells after selenite treatment. Apoptosis w...
