Background: Acquired perforating dermatosis (APD) is a rare group of skin disorders characterized by transepidermal elimination of dermal tissue material. There are only a few studies of APD. Objective: We aimed to review the clinicopathologic features of patients with APD and evaluate the outcomes of treatments. Material and methods: The medical records of 25 patients who were clinically and histopathologically diagnosed as having APD between 2006 and 2013 were retrospectively reviewed. The histopathologic sections and the results of elastic, trichrome and periodic acid Shiff (PAS) staining were evaluated. Results: Of the patients, 17 (68%) had ARPC, 7 (28%) had perforating folliculitis, 1 (4%) had Kyrle's disease. Male/female ratio was 1.3. The mean age was 51.8±12.8 years. The disease duration ranged between 15 days and 96 months. Diabetes mellitus was the most common disease associated with APD (48%). The walls of vessels were PAS positive in the lesions of 6 of 13 diabetic patients. After various treatments, almost all lesions regressed in 15 (60%) patients. Conclusion: Acquired perforating dermatosis may present with various clinical features and is mostly associated with diabetes mellitus. Diabetes mellitus may be involved in the pathogenesis of APD via microangiopathy and other mechanisms.
