The lesions involve an area between the right supraorbital rim, the base of the right ear and nape, extending partially into the fronto-occipital area on the left. b) Illustration of the same photograph that better shows the distribution and the tridimensional characters of the nodular lesions. In the center are two big circular skin lesions (asterisks) draining serous and purulent material, surrounded by multiple irregular swollen masses (arrow heads) and multiple small openings on the skin surface with tufts of hair protruding from the skin apertures (arrows). There is an extensive area around and under the ulceration characterized by thin and translucent glabrous epidermis (stars).
