Abstract

Subungual squamous cell carcinoma is rare. Its atypical presentation can mimic several diseases and therefore the diagnosis can be easily missed or delayed. It is more frequently observed on the fingernails which may be explained by a much higher sunlight exposure and a possible role of human papilloma virus infection.
We report a case of a 58-year-old man that was referred to our Department with a subungual tumour on his left fourth finger. Skin biopsy showed a Subungual squamous cell carcinoma and therefore whole nail unit was excised. Closure was performed with a full-thickness skin graft.

The nail apparatus should be fully excised for two main reasons: malignant tumour and severe posttraumatic nail dys- trophy. Amputation remains necessary in case of invasive melanoma or in any Subungual squamous cell carcinoma with bone involvement.
