Figure 2: (a) Histopathology. Low-power view that shows an attenuated epidermis and upper dermal pallor (H&E, original magnification, 40×). (b) Histopathology. High-power view demonstrating an atrophic epidermis with colloid bodies and overlying hyperkeratosis. In the underlying dermis, there is a patchy infiltrate of lymphocytes, melanophages, and hypovascular mucinous fibrosis (H&E, original magnification, 200×). (c) Histopathology. Below the altered wedge-shaped dermal zone, there is a small damaged vessel occluded with thrombus and surrounded by lymphocytes and extravasated erythrocytes. There is basement membrane zone reduplication (H&E, original magnification, 400×). (d) There is marked mucin deposition throughout the entirety of the biopsy specimen (Alcian blue, original magnification, 100×)
