A 60-year-old female patient presented with dark slow growing plaque on the abdomen since 5 years. The lesion initially was asymptomatic, and recently it was associated with itching. No history of bleeding, discharge, or ulceration of the lesion or any systemic complaints, and no history of similar complaints in the family was found.

Clinical examination revealed single, well-circumscribed, darkly pigmented, rough-surface (cribriform surface) indurated plaque of around 5 cm diameters, present on the abdomen [Figure 1]. Hair, nail, mucous membranes, general physical and systemic examinations were normal. A punch biopsy from the nodule was done. The histopathological features from hematoxylin and eosin-stained tissue section are shown in [Figure 2]a and b.
