Squamous cell carcinoma subsequent to scarring caused by sporotrichosis: A case report.

BACKGROUND: Sporotrichosis is a fungal disease caused by the Sporothrix schenckii species complex. It is usually acquired by trauma with plants. Lymphatic-cutaneous is the most common clinical manifestation. CASE REPORT: The present case describes the development of an epidermoid carcinoma as a late complication on a long evolution sporotrichosis scar. During a period of 50 years, the patient had lesions in the right hand. Sporotrichosis was diagnosed and treated with potassium iodide. Eleven years after the healing of the lesions, a squamous cell carcinoma on the scar of this mycosis was diagnosed. CONCLUSIONS: The chronic sporotrichosis injury was probably the cause of the tumor developed on the scar.
