Abstract

Collision tumors are two or more distinct neoplasms coexisting at the same anatomical location. The pathogenesis and nomenclature of cutaneous collision tumor is still ambiguous. We reported a case of 0.3 cm cutaneous lesion on the nose of an elderly female patient. Histological examination released a collision tumor of malignant melanoma in situ and basal cell carcinoma, which were adjacent to each other. Immunohistochemistry staining of SOX-10 and MOC31 confirmed the morphological findings. This case is consistent with the current literature that coexistent malignant melanoma and basal cell carcinoma is the most frequent combination of collision tumors.
