A rare case of perianal granular cell tumour in a 75-year-old female

Abstract

Granular cell tumours (GCTs) are a rare type of soft tissue tumour that can be found in many anatomical locations however its occurrence in the perianal region is exceedingly rare. GCT typically presents as a firm painless mass, and therefore, it may be mistaken for other more common anorectal pathology. Most are benign, however 1-2% of GCTs are malignant. Complete surgical excision is recommended for accurate diagnosis and adequate treatment. This case reports a 75-year-old female who was found to have a perianal GCT.
