Acral lentiginous melanoma misdiagnosed as tinea pedis: a case report

The incidence of acral lentiginous melanoma (ALM) varies in different ethnic groups. Volar skin is a relatively infrequent site of malignant melanoma in Caucasian patients, although the foot is the most common site of involvement in Asian and African populations. Diagnosis of ALM is usually delayed and melanomas can be diagnosed at advanced clinical stages, so the prognosis is often poor. We present a Caucasian Turkish man with ALM on the interdigital site of his foot, however, as a result of maceration of the surrounding skin, it seemed to be tinea pedis.
