Microcystic reticular schwannoma of the colon.
form the third commonest group of mesenchymal tumors within the gastrointestinal tract. They occur with a frequency of approximately 5%, which compares with 50% for gastrointestinal stromal tumors (GIST) and 30% for smooth-muscle neoplasms [1]. In 2008, Liegl et al. described 10 cases of microcystic reticular schwannoma as a distinct variant with predilection for visceral sites [2]. Herein, we ...
متن کاملMesenteric Microcystic/Reticular Schwannoma: A Diagnostic Dilemma
Microcystic/reticular schwannoma is a rare variant of schwannoma with a predilection for visceral locations including the gastrointestinal tract. Due to overlapping features with other tumours, unawareness of this tumour type may lead to diagnostic pitfalls. We here report a case of microcystic/reticular schwannoma arising in the mesentery of a 25-year-old female. The tumour was incidentally di...
متن کاملPrimary adrenal microcystic/reticular schwannoma: clinicopathological and immunohistochemical studies of an extremely rare case.
A case of primary adrenal microcystic/reticular schwannoma affecting the right adrenal gland in a 31-year-old female was reported. Histologically, the tumor significantly consisted of strikingly anastomosing strands of spindle cells imparting a microcystic and reticular pattern with a focal transition to epithelioid nests. Immunohistochemically, S-100 and CD56 protein showed a uniform and stron...
متن کاملMicrocystic/Reticular Schwannoma of the Frontal Lobe: An Unusual Occurrence
Schwannoma is a benign peripheral nerve sheath tumor that typically involves cranial nerves of the head and neck region. Intraparenchymal occurrence of this tumor is uncommon. Even rarer in this site is the microcystic/reticular pattern of schwannoma. This histologic variant, first described in 2008, has a predilection for visceral organs. Herein, we report the first case of microcystic/reticul...
متن کاملMicrocystic/Reticular Schwannoma of the Mandible First Case Report and Review of the Literature
Schwannoma comprises a group of nerve sheath tumors. Morphologic variants of schwannoma have no distinct relationship to clinical behavior, but unawareness of rare variants may lead to diagnostic pitfall and risk of mistreatment. Microcystic/reticular schwannoma is a recently described rare variant of schwannoma. We report a case of a 61-year-old female with a 5.0 cm × 3.5 cm × 3.0 cm mass in t...
