title: Diffuse trichostasis spinulosa in chronic renal failure.
abstract: Trichostasis spinulosa is a relatively common but underdiagnosed disorder of the pilosebaceous follicles in which there is follicular hyperkeratosis of a dilated vellus hair follicle with retention of successive telogen hairs arranged in parallel among keratinaceous material. The condition is apparent as dark follicular plugs in the affected areas, most commonly affecting the face (nose and cheeks) or the trunk (interscapular area in particular). We describe a 33-year-old Indian man who was on haemodialysis for chronic renal failure and who developed unusually widespread trichostasis spinulosa over almost the entire body including the lower limbs over a period of 18 months.
