Osteoma cutis masquerading as an ingrowing toenail: a case report

Osteoma cutis of the foot is extremely rare and there are very few reported cases. The incidence of in-growing toenail in the United Kingdom is estimated to be 10,000 new cases per year and many are treated non-operatively. We present a case where osteoma cutis was masquerading as an in-growing toenail, and wish to highlight the condition as a differential diagnosis for this condition. There have been case reports of bony cutaneous lesions of the foot, both benign and malignant and so these are especially important to consider in the differential diagnoses where non-operative management is being considered.
