A case report of malignant melanoma of the great toe.

UNLABELLED: Melanoma is reported as the most common malignant neoplasm of the foot and carries with it a very poor prognosis. This neoplasm arises from melanocytes, which are pigment-producing cells found predominantly in the skin, and the malignancy can metastasize to any organ system. Early and accurate diagnosis and treatment are paramount components of a successful course of management, and improve the rate of survival for those affected by this aggressive cutaneous neoplasm. In this report, we describe an invasive case of melanoma of the hallux that was misdiagnosed as a chronic ingrown and infected nail.

LEVEL OF CLINICAL EVIDENCE: 4.
