Abstract
Cellular schwannoma (CS) occurring in the foot is uncommon, and when it does occur, it usually presents as a slowly growing tumour. Ulceration of CS on the foot is rare. We report a 20-year-old woman who presented with a painful and non-healing ulcer on the lateral area of the right great toe, which failed to heal despite treatment. Six months after onset of the ulcer, a small swelling appeared below it. Histological examination of a biopsy taken from the edge of the ulcer established the diagnosis of CS. Preoperative magnetic resonance imaging delineated the mass on the lateral area of the right great toe. The mass was surgically excised, which led to resolution of the symptoms. This case highlights the fact that chronic ulcers in the foot can be due to CS. Correct diagnosis and management depend on a histopathological diagnosis.
