汗孔角化病是一种临床上以环形斑块为特征的皮肤病，其边缘呈角化状，类似于中国的长城，组织病理学上以角化样板层为特征。这种疾病有几种临床变异。最近已成为这些变种的一部分的嗜褶性汗孔角化病是相当罕见的，鲜为人知。该实体的特征是疣状斑块-可能类似于银屑病斑块-影响臀部区域，最常见的是臀裂，有或没有肢体受累。经常出现瘙痒。我们报告一例罕见的汗孔角化症ptychotropica，并强调其不寻常的表现（单一斑块），在巴西文献报道的第一例。
Porokeratosis is a skin disorder clinically characterized by annular plaques with keratotic borders resembling the Great Wall of China and histopathologically by cornoid lamellae. The disease has several clinical variants. Porokeratosis ptychotropica, which has recently become part of these variants, is quite rare and little known. The entity is characterized by verrucous plaques – which may resemble a psoriasis plaque – that affect the regions of the buttocks, most commonly the gluteal cleft, with or without extremity involvement. Itching is often present. We report a rare case of porokeratosis ptychotropica and highlight its unusual manifestation (single plaque), the first case reported in the Brazilian literature.
