Schwannomas of the kidney are rare, with only a few reported cases. We report three additional cases with immunohistochemical analysis. All three tumors were from females (aged 27, 35, and 59 years) and ranged from 4.8 to 8 cm in diameter. All of the patients underwent nephrectomy. The tumors were totally or partially encapsulated; two were in the hilum and one was centered in the renal cortex. All tumors were diffusely positive for S100 protein. Two were positive for neuron-specific enolase. Immunostaining for neurofilament, HMB45, microphthalmia transcription factor, smooth muscle actin, CD34, cytokeratin AE1/3, cytokeratin 7, and CD10 were negative. Follow-up data were available for two patients; neither had tumor recurrence or metastasis. In conclusion, renal schwannoma is rare, usually arises centrally, impinging on the hilum or the pelvis, and is cured by resection. Sarcomatoid carcinoma and other spindle cell tumors should be considered in the differential diagnosis.

Sarcomatoid carcinoma of the gallbladder, composed of epithelial and sarcomatous components, is a rare malignant tumor with a poor prognosis. A 61-year-old man was admitted because of abdominal distention for 2 weeks. Enhanced CT showed a large gallbladder tumor with central necrosis. The tumor measuring 18 cm in maximum diameter showed intense peripheral FDG uptake with SUVmax of 15.4. The specimen of the resected tumor revealed tubular adenocarcinoma and sarcomatoid tissue with chondroid differentiation. Immunohistochemical staining showed the sarcomatoid tissue was positive for EMA, CD10, and VIM, with proliferation index of 80%. These pathologic findings were consistent with sarcomatoid carcinoma.
