sertoli cell tumors of the testis are extremely rare tumors with a heterogeneous pathology. three histological variants have been described: sertoli cell tumor not otherwise specified (nos), large cell calcifying sertoli cell tumor and the sclerosing sertoli cell tumor. the sclerosing sertoli cell tumor described herein is associated with prominent stromal sclerosis. they present as painless sc...

Desmoid tumor is a rare soft tissue and accounts less than 1% of retroperitoneal tumor. It pathologically benign tumor, while clinical behavior aggressive, showing high rate local recurrence. consists spindle cell, collagen myxoid matrix thus it shows diverse imaging patterns according to its composition. In this case report, surgically diagnosed desmoid presented.

schwannoma(neurilemmoma) is a benign tumor originates from schwann cells. ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. the mandible is the most common site of occurrence for this lesion. we report a rare case of intraosseous ancient schwa...

Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...

Congenital epulis is a very rare benign soft-tissue tumor of uncertain histogenesis, which is also known as “gingival granular cell tumor of the newborn”. It occurs almost exclusively as a single tumor along the alveolar ridge of the maxilla in newborn females. Although congenital epulis is strikingly similar to the more common adult granular cell tumor histologically, in contrast to the latter...

among the rare bone tumors, the osteoblastoma is a fascinating tumor. the rarity, the predisposition to occur in any bone and the diagnostic dilemma makes this infrequent tumor interesting. it is sporadically reported in the literature and what is rarer is its occurrence in the pelvis. the unusual location and inconclusive radiographic findings with diffused diagnostic evidences delays the mana...
