Clear cell acanthoma (CCA) is an uncommon, benign, and slow progressing lesion originating from epidermal keratinocytes. Lesions are not gender specific and usually diagnosed at 50-60 years of age. It is generally represented in the lower extremities. CCA was first described by Degos et al. as "Degos acanthoma" for a lesion presented in the lower extremity. Clinically, it is hard to distinguish whether the lesion is benign or malignant. Final diagnosis can be made histopathologically. Biopsy material is periodic acid-Schiff positive. While CAA commonly presents itself in the lower extremities, our patient had a CAA in his abdominal region.
