Subcutaneous granular cell tumour of the lumbar region.

Granular cell tumour (GCT), also known as Abrikossoff tumour, is an uncommon neoplasm, probably of neural origin derived from Schwann cells. It usually presents as a subcutaneous solitary asymptomatic nodule. It has been the subject of much debate in the literature concerning the tumour origin and the association with other malignancies. We report a case of subcutaneous GCT in the lumbar region in a 31-year-old Caucasian male. Although they are a rare entity, GCTs should be considered in the differential diagnosis of the subcutaneous soft tissue tumours. Surgical removal with wide margins is the treatment of choice as malignant changes have been reported after long-term follow-up.
