Abstract
- Porokeratosis is a genodermatosis that is characterized by abnormal epidermal keratinization with the histologic finding of a cornoid lamella. Linear porokeratosis is an uncommon variant that presents a characteristic linear nevoid distribution along the Blaschko's lines and linear porokeratosis has the highest potential for malignant degeneration of all the porokeratoses. Many treatment modalities have been used, but the treatment outcomes are variable and the treatments are poorly standardized. We report here on a case of linear porokeratosis in a 48-year-old female who showed localized, linear, brownish macules with a well-demarcated hyperkeratotic border on the left lower abdomen and back.
