Summary
Brief summary (as posted)
Basal cell carcinoma (BCC) is the most frequent neoplasia worldwide. There are more than 30 histopathologic subtypes, however the nodular subtype is the most common. Pigmented varieties are common in darker skin types, therefore in our country. Previous studies have shown an increase number and size of melanocytes. Melanogenesis were increased at the expense of hyperfunctioning melanocytes as well. The aim of the study was to describe the characteristics of melanocytes in pigmented and non-pigmented variants of basal cell carcinoma.
