Intranodal Palisaded Myofibroblastoma of Inguinal Region, a Rare Benign Lesion: Case Report

Intranodal Palisaded Myofibroblastoma is a benign lesion characterized by intranodal proliferation of cells with myofibroblastic origin. It shows striking histopathological features characterized by spindle cells with nuclear palisading, intralesionalhaemorrhage, amianthoid fibers, intracellular and extracellular fuchsinophilic bodies, abundance of mast cells and compressed remnant lymphoid tissue at the periphery. Immunohistochemically the spindle cells are Vimentin, Beta catenin and SMA positive and are negative for S 100, with low ki-67 index. Palisaded Myofibroblastoma is a rareintranodal entity and it needs to be differentiated from Schwannoma which it closely resembles. Here we report a case of a 52 years old male patient who presented with mass in the left inguinal region.
