[Solitary Fibrous Tumor of the Kidney].

A 59-year-old woman was referred to our hospital with the finding of an incidentaloma in her right kidney. Computed tomographyand magnetic resonance imaging showed a solid tumor, approximately8 cm in diameter, at the lower pole of the right kidney. Partial nephrectomy was performed without a renal vessel clamp.

[Case of local recurrence of the periurethral proximal-type epithelioid sarcoma successfully treated by repeated regional excision].

Proximal-type epithelioid sarcomas are rare soft tissue neoplasms occuring in the soma or thigh and often repeat recurrence and metastasis. We present a case of locally recurrenced proximal-type epithelioid sarcoma that could be treated by regional excision alone. A 62-year-old man visited our institute for a growing mass in the perineal region.

[A case of adrenocortical adenoma coexisting with gastrointestinal stromal tumor].

A 48-year-old man was referred to our institute for the evaluation of a concomitant gastric submucosal tumor and right adrenal tumor, incidentally found by ultrasound examination. Computed tomography showed a mass with a diameter of 6 cm adjacent to the stomach and the right adrenal tumor with a diameter of 3 cm. These tumors had similar characteristics in both plain and enhanced imagings.

Anterior distribution of Stage T1c nonpalpable tumors in radical prostatectomy specimens.

Objectives: To determine the anatomic patterns of tumor distribution in radical prostatectomy specimens from nonpalpable prostate cancer.

Methods: Tumor maps directly traced from histologic slides of 62 radical prostatectomy specimens were superimposed by a computer-assisted imaging technique to create an idealized prostate gland at three levels: apex, mid-prostate, and base. To investigate specific patterns of tumor distribution, the sites of tumor in each quadrant were compared according to risk group stratification.
