Figure 1: Multiple self-healing lesions on the trunk (a) and limbs (b,c,d,e,f,g). Tumors are dome-shaped with a central keratotic plug, covered with crusts and blood spots (c). Some of the lesions were clustered leaving Blaschko-linear pitted scars (b). Dermoscopic examination showed a central structureless red-purple keratotic crater surrounded by a structureless while area with white circles surrounding hair follicles and linear, serpentine, and looped vessels (h).
Figure 2: Histopathological examination. (a- Hematoxylin and eosin, x40) Symmetric cup-shaped proliferation squamous cells with a central keratinous crater. (b- Hematoxylin and eosin, x200) the proliferation is made of glassy squamous cells containing abundant eosinophilic and translucent cytoplasm. Mitosis and numerous dyskeratotic cells are visible. (c- Hematoxylin and eosin, x200) Lymphocytic inflammatory infiltrate surrounding deep lobules of atypical squamous cells
