title: Case for diagnosis.
abstract: Acquired perforating dermatosis is a rare condition often associated with some systemic diseases, especially diabetic patients with chronic renal failure undergoing dialysis. The main symptom is pruritus and it is clinically characterized by the presence of redish-brown papular lesions in the trunk, head and neck. Biopsy of the lesion reveals epidermal invagination with keratotic plug. The etiology is poorly understood and several therapeutic measures have been disappointing.
