AbstractAbstract PDF
Small bowel tumors have been difficult to diagnose because of low incidence and absence of specific symptoms. There are no efficient and accurate tests available for diagnosis. Capsule endoscopy is an efficient diagnostic tool for small bowel disease and obscure gastrointestinal bleeding. We diagnosed two cases of small bowel gastrointestinal stromal tumor (GIST) diagnosed by capsule endoscopy that were treated by surgery. A 68 year old male presented with abdominal pain. The capsule endoscopy showed fungating ulcer mass at the jejunum. A 55 year female presented with melena. The capsule endoscopy showed an intraluminal protruding mass with a superficial ulcer at the jejunum. Two cases were diagnosed with GIST after surgery. We report these two case diagnosed by capsule endoscopy and review the medical literature.

AbstractAbstract PDF
Mesenchymal chondrosarcoma is a rare malignant tumor of skeletal and extraskeletal origin, and which shows aggressive local behavior as well as a high metastatic potential. We report 3 cases of mesenchymal chondrosarcoma. Two cases were male and one was female. The ages ranged from 25 to 32 years(mean: 28 years). Tissue was obtained by wide excision in two patients, and incisional biopsy in one. The mass locaterd in the rib(case 1), orbital floor(case 2), and abdominal wall(case 3). Roentgenographically, the tumor resembles ordinary chondrosarcoma, showing osteolytic and obstructive appearance with stippled calcification. Grossly, the tumor was lobulating, solid fish-fleshy like mass with calcification and ossification. Histologically, the tumor shows characteristic bimorphic pattern composed of islands of well differentiated hyaline cartilage admixed with a cellular area of undifferentiated small cells. The small cells usually displayed a hemangiopericytoid or an alveolar pattern.
