Small bowel metastases due to lung cancer are extremely rare and predominantly cause intestinal obstruction, perforation gastrointestinal bleeding. We report the case of a 51-year-old man diagnosed with pulmonary sarcomatoid carcinoma which an ileal mass was subsequently removed found be compatible localization carcinoma.

Sarcomatoid variant of anaplastic large cell lymphoma (ALCL) is one of the rarest histologic variants of ALCL that consists of large, bizarre, often spindle-shaped, neoplastic cells resembling a soft tissue sarcoma. We report here such a case of ALCL with both pulmonary and multiple nodal involvement in a 47-year-old woman who initially presented with fever, cough, sputum, itching skin, and wei...

Study Design Case report. Objective Malignant mesothelioma (MM) is an uncommon tumor of the pleural epithelium with a predilection for local spread into adjacent tissues. The sarcomatoid type accounts for ∼10% of MM cases and is associated with poorer survival than the epithelioid, desmoplastic, and biphasic types. MM commonly presents with involvement of the vertebral body or epidural space. H...

This study presents a case of metastatic sarcomatoid renal cell carcinoma (RCC) treated with systemic chemotherapy followed by mammalian target of rapamycin inhibitor maintenance therapy. A 63-year-old male presented with lumbago, and lumbar vertebral tumors were detected by magnetic resonance imaging. Subsequent computed tomography (CT) revealed a right renal tumor and CT-guided biopsy of the ...

Aggressive adult granulosa cell tumor (AGCT) of the ovary remains uncommon. We report a case of aggressive AGCT of the ovary who had rapid recurrence at two months after surgery. A patient was referred for further examination of a pelvic tumor. She underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy. In the areas showing a sarcomatoid pattern, the...

Background Sarcomatoid bladder cancer is a rare and aggressive variant of urothelial carcinoma. Methods A retrospective review of our experience in managing patients with sarcomatoid bladder cancer (SRBC) between 1997 and 2011 was performed to better define the behavior and outcomes of this disease. Results The median age of the patients was 63 years. All patients presented with high grade ...

PURPOSE Existing prognostic systems for malignant pleural mesothelioma do not incorporate imaging information. We aimed to identify the contribution of quantitative fluorodeoxyglucose positron emission tomography (FDG-PET) analysis to other prognostic variables in this disease. EXPERIMENTAL DESIGN Patients with malignant pleural mesothelioma underwent helical thoracoabdominal computed tomogra...

Objective: To explore the clinical, pathology, and prognosis of sarcomatoid carcinoma of the renal pelvis. Methods: A case of the diagnosis and treatment of sarcomatoid carcinoma of the renal pelvis in our hospital were retrospectively analyzed. Articles were searched from the full-text databases, such as NCBI and PUBMED, the dates of clinical and pathology was collected from the satisfied arti...
