title: Sclerosing cellular blue nevus simulating melanoma.
abstract: Sclerosing blue nevus is an uncommon variant of common blue nevus and shows an amorphous blue appearance at the edges with a hypopigmented center. Herein we present a 48-year-old female with sclerosing cellular blue nevus with extraordinary clinical and dermoscopic features simulating melanoma. The association of a whitish scarlike area with a pigmented dot pattern prominent throughout the lesion was unusual for a sclerosing cellular blue nevus. Besides pattern asymmetry, polychromasia and linear irregular vessels increased the mimicry. This case illustrates the importance of surgical excision and histopathological examination.
