title: Pigmented basal cell carcinoma and superficial spreading malignant melanoma: an unusual combination.
abstract: We report pigmented lesions in 2 white male patients, which were clinically diagnosed as superficial spreading malignant melanoma and histologically showed combined features of superficial spreading malignant melanoma in situ and pigmented basal cell carcinoma. The significance of this association is not known but is most likely very rare.
