Giant cell tumor of the small bones of the hands and feet is rare. Giant cell tumors in these locations develop at young age, are more commonly multifocal, and show the higher risk of recurrence than those at the end of the long bone. It should be differentiated from the other lesions of the hands, such as giant cell reparative granuloma, aneurysmal bone cyst and enchondroma. We experienced a case of giant cell tumor in the proximal phalanx of the left hand with swelling and pain. Curettage and bone graft were performed. Histologically large number of giant cells were distributed diffusely in the highly cellular stroma containing sheets of mononuclear cells. Secondary aneurysmal bone cyst and hemorrhage were associated.

Chondromyxoid fibroma occurring in the hand is a rare benign tumor. Radiologically and histologically, it should be differentiated from the other benign bone lesions in the hand, such as enchondroma, chondroblastoma, giant cell reparative granuloma and chondrosarcoma. This report is dealt with 59-year-old female and 19-year-old male patient presenting lesions on their digits anddescribed unusual clinical, radiological and pathological features.

Desmoplastic fibroma is a rare primary tumor of bone that histologically and biologically mimics the extra-abdominal desmoid tumor of soft tissue. This report is dealt with two cases of desmoplastic fibroma occurring in a 22-year-old male, scapular lesion and 34-year-old male, pubic lesion. Radiologically, the tumors were lucent and expansile lesions. Histologically, they contained slender spindle cells and various amounts of collagen fibers. Radical excision was done on both cases and no recurrence was reported. Because of its rarity, we report two cases of desmoplastic fibroma.

Epithelioid sarcoma has been well characterized as a distincitve entity. In the classic form, it occurs in the distal extremities of young adults. However, in the proximal form, it was found mostly in the pelvis, perineum, and genital tract of young to middle-aged adults. Morphologically, the tumor cells had promient epithelioid or rhabdoid features with marked cytologic atypia, and grew in a multinodular pattern. Immunohistochemically, cytokeratin, epithelial membrane antigen, and vimentin were positive in the tumor cells. This reports dealt with 32-year-old male lesion on his perineum. The tumor shows typical features of proximal type epithelioid sarcoma. We also discussed pathological differential diagnosis and prognosis on this particular disease.
