A 50-year-old man was referred to our clinic for further evaluation of a slowly enlarging plaque on his back. His wife gave history of the pimple-sized brownish lesion first being noticed thirty years earlier. Ever since, the lesion has been presenting slowly and continuously enlarging. On examination, the patient, a healthy looking man, had a brownish-red, shiny, well-demarcated, 6.0 mm elevated, rubbery consistency, a 7.8 x 8.2 cm dimension, hairless plaque with peau d'orange surface and 'pasted on' appearance on the left side of his back. The margins of the lesion were surrounded by a brownish zone. The patient did not have any complaint except a slight tingle in the lesion after stroking, pressure, or friction. Inflammatory flare characterized with redness, swelling, and pseudovesiculation was observed in the lesion after stroking [Figure 1A]. The inflammation and pseudovesiculation gradually decreased within a few days. Then, desquamative scales developed over the lesion [Figure 1B].

His systemic examination was unremarkable, and routine laboratory tests were within normal limits. There was no family history of similar skin lesion.

A skin biopsy specimen was obtained [Figure 2].
