Two Cases of Subungual Squamous Cell Carcinomas / 대한피부과학회지

ABSTRACT

Subungual squamous cell carcinoma is a rare malignant tumor arising on the nail bed and it has resemblance to a variety of inflammatory skin diseases and cutaneous tumors. The diagnostic biopsy is essential but it is often delayed because of patients' reluctance, technical difficulties, or lack of awareness by physicians and inappropriate treatment is given for other suspected conditions, especially fungal or bacterial infections and for warts. We report two rare cases of subungual squamous cell carcinoma and emphasize the need of diagnostic biopsy on the subungual lesions that have resistance to the conventional treatments.
