Resumo
Alopecia areata is a common autoimmune disorder that leads to nonscarring hair loss. Black dots, also called comedo-like cadaver hairs, can be found in almost 50% of alopecia areata patients and indicate disease activity. Trichostasis spinulosa is a follicular disorder resulting from the retention of numerous hairs surrounded by a keratinous sheath in dilated follicles. Trichostasis spinulosa is a relatively common but underdiagnosed disorder of hair follicles. Here, we describe a man with alopecia areata of the eyebrows, androgenetic alopecia and trichostasis spinulosa at the vertex and show how dermoscopy can be useful in distinguishing black dots from Trichostasis spinulosa lesions.
