SUCCESSFUL CRYOTHERAPIC TREATMENT AND OVERVIEW OF MULTIPLE CLEAR-CELLACANTHOMAS

BACKGROUND. Clear cell acanthoma (CCA) is a usually solitary benign ep idermal tumor. Multiple lesions are infrequently reported. OBJECTIVE. A case of multiple eruptive CCA is reported in which a successful cryo therapic treatment was performed. METHODS. A 59-year-old man with vari cose veins and dry skin presented with 17 eruptive asymptomatic papulo -nodular lesions on both legs. RESULTS. Two lesions were excised with a histologically confirmed diagnosis of CCA. Other lesions were treate d with liquid nitrogen. All the lesions resolved with minimal residual scarring after three to four treatments. CONCLUSIONS. Multiple CCA is a rare condition; fewer than 20 cases having been described. The pres ence of associated conditions like dry skin and varicose veins are dis cussed. Because of the tendency of persistence of the lesions, cryothe rapic treatment may be a useful method of therapy.
