Abstract

The coexistence of more than one neoplasm in a single cutaneous specimen is uncommon and has been defined as collision or compound tumor. The authors describe a 66-year-old man who presented with a contiguous seborrheic keratosis and a basal cell carcinoma on the left malar region that had developed in about one year. The case was investigated clinically and focusing on the dermoscopic features and histopathological correlates. Dermoscopy of the lesion revealed milia-like cysts corresponding to the verrucous part of the lesion, whereas the erythema at the periphery disclosed a few arborizing vessels. Histologically the lesion was a seborrheic keratosis and a basal cell carcinoma. Hence, histopathology confirmed the dermoscopic diagnosis of a compound tumor. Dermoscopy is not only an important aid to the diagnosis of cutaneous collision tumors but might additionally turn the attention of histopathologists to any peculiar feature of a given lesion.
