Abstract:
Blue nevus is a dermal melanocytic disorder, and there are two types of blue nevi are generally recognized; the common blue nevus and the cellular blue nevus. Although cellular blue nevus might show malignant transformation in rare cases, common blue nevus is considered completely benign. We report a case of common blue nevus with clinical indicators of malignant change, the loss of regular border and the development of satellite lesions, but showing histopathologically benign finding. A 29-year-old male patient with blue-black colored, 1cmx1cm sized nodule on right hand dorsum is presented. This lesion had been presented for at least 7 years, but it began to grow with irregular border and some satellite lesions from about 5 months ago. Under the impression of malignant blue nevus, a biopsy was performed. The histopathological examination showed that the nevus cells were dispersed in the papillary and reticular dermis, without any malignant changes.
