A Case of Subungual Squamous Cell Carcinoma / 대한피부과학회지

ABSTRACT

Subungual squamous cell earcinoma is an uncommon disease. Diagnosis of this condition is often delayed because of a resemblance to a variety of benign inflammatory conditions such as onychomycosis, chronic paronychia, eczema, and verruca vulgaris. The importance of an early skin biopsy for a chronic nonhealing subungual lesion is stressed. We present a case of subungual squamous cell carcinoma iri a 75-year-old man who had a 3-year history of intermittent swelling, erythema, and tenderness on the left 5th toe. The patient complained of a tender whitish verrucous 1.5cm-sized mass which had been present for a few months. A Histopathological study revealed invasive, well differentiated squamous cell carcinoma.
