Abstract

An 84-year-old woman had an ovoid shallow ulcer with an elevated, indurated, pigmented border on the left cheek. Histological examination revealed a moderately differentiated squamous cell carcinoma and a solar keratosis with abundant melanocytes and melanin pigment. Ultrastructurally, the keratinocytes contained numerous melanosomes in their cytoplasms and the melanocytes in the squamous cell carcinoma and the solar keratosis had mature melanosomes.
