Abrikossoff's Tumor: An Unusual Presentation.

Abrikossoff's tumor or granular cell tumor is an infrequent benign neoplasm, first described by the Russian pathologist Abrikossoff in 1926. The neoplasm can affect all parts of the body with head and neck areas affected in 45-65% of patients. More than half of the head and neck lesions are localized to the oral cavity, especially the tongue. An aggressive malignant form of granular cell myoblastoma that metastasizes is rare. The treatment of choice of Abrikossoff's tumor is local surgical excision with a wide margin. Here, we present a case of Abrikossoff's tumor, occurring in the upper arm, presenting as a panniculitis-like lesion.
