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.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
