Abstrakt:	Subungual melanoma is associated with the highest mortality among all skin cancers and is strongly linked to acquired mutations caused by exposure to ultraviolet radiation in sunlight. The commonest sites of occurrence are the great toe and thumb. Diagnosis of melanoma often becomes a challenge as it is difficult to differentiate it from other pigmented disorders. A histopathological evaluation of the lesion with adequate nail matrix biopsy can address the diagnostic dilemma. Additionally, an early diagnosis of melanoma is critical as once detected early, it is often treatable. We present a case of a 72-year-old diabetic male patient with a pigmented lesion over the right great toe. In view of the patient's age and history of diabetes, the initial presentation was mistaken as onychomycosis which created a diagnostic dilemma. Hence, we present this case to shed light upon the fact that these lesions can mimic several other benign conditions like fungal melanonychia, lentigo, and subungual hemorrhage. To avoid misdiagnosis and subsequent delay in management, early clinical, dermoscopic, and very pertinently, histopathological and radiological co-relations are extremely important.
