Department of Oral Diagnosis, Federal University of Pernambuco, Recife, Brazil Melanin impregnation in squamous cell carcinoma (SCC) is an uncommon histological finding. Rare nonmelanocytic entities were previously described as having melanocyte colonization. A 57-year-old Brazilian woman was referred with a pigmented lesion in the lower lip and alveolar ridge with a prior clinical diagnosis of melanoma. The incisional biopsy of the tumor revealed an SCC with strong colonization of melanocytes in the stroma. The authors report a case of an unusual SCC variant and a brief review of the literature.
Key Words: squamous cell carcinoma melanocyte colonization melanin oral mucosa
