An unusual Cellular Blue Nevus involving Phalangeal Bone
Abstract
- A 34-year-old female had an unusual case of cellular blue nevus which had behaved in a locally aggressive fashion. The lesion infiltrsted the adjacent soft tissue of left nail bed and extended into deep phalangeal bone. The involved left thumb was partially amputated because complete excision was impossible and we were quite concerned about malignant transformation. Histologically biphasic pattern without cellular atypism, a characteristic features of cellular blue nevus, was shown. About 2 years later, the lesion had not recurred.
