Clear cell acanthoma (CCA) is an uncommon benign epidermal tumor of unknown origin and etiology. It is often solitary, and the presence of multiple CCAs in the same individual is rare. Typically, it presents as a slowly growing plaque or nodule located on the legs with a peripheral scaling collarette. Diagnosis is primarily based on clinical and histopathological findings, with dermoscopy enhancing diagnostic accuracy. The differential diagnosis includes various skin tumors and inflammatory dermatoses. The preferred treatment is surgical excision, as these lesions do not regress spontaneously. We describe a case of a large CCA on the right thigh associated with multiple small nodular lesions scattered across the legs.
