Abstract
Porokeratosis ptychotropica (PP) is a rare variant of porokeratosis, typically presenting as pink to brown hyperkeratotic plaques in the gluteal cleft and buttocks, defined histologically by multiple cornoid lamellae. Diagnosis of PP is challenging due to its clinical overlap with other dermatologic conditions and inconsistent terminology in the literature. This case report describes a 47-year-old woman exhibiting clinical and pathological features of PP but with a more diffuse presentation than previously documented. The case emphasizes the diagnostic complexities of PP, particularly in atypical presentations, and highlights the critical role of histological examination in distinguishing it from other porokeratoses.
