• 322-03Tumor of the buttock24 女性

  Kazuhito Hatanaka/Dept. of Molecular and Cellular Pathology

  The patient complained of approximately 5-year history of left coxalgia. CT revealed a 6cm-sized soft tissue mass located between the left greater trochanter and the left tuber ischiadicum. MR images showed a multiloculated cystic component without invasion of surrounding structures. Histological diagnosis was undetermined in biopsy specimen. The surgical resection was performed for the definite diagnosis.

• 322-04Retroperitoneal tumor61 男性

  Yuichi Yamada/Dept. of Anatomic Pathology, Kyushu University

  The patient suffered from discomfort in the abdomen and was pointed out 8.5cm-sized heterogenous mass in the retroperitoneal area by contrast enhanced CT imaging.

  M. Hisaoka/Dept. of Pathol. & Oncol., UOEH

  The patient noticed a rump in the instep of the left foot for approximately five years. She visited the orthopedic department of a regional hospital and was found to have a soft tissue tumor, measuring about 3 x 2 x 1 cm in diameter, in a radiological examination. Because of the diagnosis of malignant tumor made by excisional biopsy, re-excision was done to obtain a clear safety margin 20 days later. She was well without evidence of disease or metastasis nine years after surgery. The provided histologic slide was prepared from the biopsy specimen.

• 322-06Tumor of the buttocks58 女性

  Reiichiro Kondo/Kurume University School of Medicine

  The patient visited nearby hospital with a complaint of small mass at her left buttocks three months ago. The mass tended to enlarge rapidly, and became 10cm in diameter.

  A 54-year old Japanese male presented with a 4-month history of an ulcer on his left lower leg, where he initially had a pigmented lesion from his infancy. He underwent surgical excision and malignant vascular tumor was suggested in other hospital. Wide-excision was performed in our hospital, because of the positive surgical margin at the first operation. The resected specimen showed an ulcerative lesion of 12x6 cm. The distributed section was obtained from the first operation.
