A Case of Common Blue Nevus with Satellite Lesions / 대한피부과학회지

We experienced a patient who presented with a common blue nevus with satellite lesions. A 56-year-old woman was presented with a 0.7x0.9cm sized dome-shaped blue-black papule and five dotted and linear blue-black macular satellite lesions on the right arm. The clinical manifestation was suggestive of peripherally disseminating malignant melanoma. Histopathological examination of the main lesion as well as the satellites showed the appearance of common blue nevus without malignant change.

A Case of Acquired Bilateral Nevus of Ota-like Macules Accompanying the Common Blue Nevus / 대한피부과학회지

Acquired bilateral nevus of Ota-like macules is representative among acquired dermal melanocytoses. In contrast to the blue nevus commonly occuring at birth, it can occur in childhood and adulthood. We report a 44-year-old woman, who had developed the acquired bilateral nevus of Ota-like macules and the common blue nevus on the left forearm concurrently for approximately 7 years. The characteristics of late onset and the distribution of sun exposure areas seems to imply a common pathological origin in their development.

A Case of Common Blue Nevus with Irregular Border and the Satellite Lesions / 대한피부과학회지

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.
