Resumo: Trichostasis spinulosa (TS) is a common follicular disorder that results from the retention of multiple vellus hairs within pilosebaceous follicles. A variety of treatment modalities have been used with variable but largely transient success.: To determine whether a pulsed diode laser irradiation would provide a therapeutic response to TS for a prolonged period.: Thirteen subjects with untreated TS and skin phototypes III, IV, and V were treated with a 800-nm pulsed diode laser at fluences ranging from 24 to 40 J/cm2 (mean, 36 J/cm2) and a 12- to 20-ms (mean 18 ms) pulse width. Two treatments were delivered at 4-week intervals. Evaluation of improvement was performed at 4 and 20 weeks after the last treatment by a blinded assessment of clinical photographs.: Complete clearing of the lesions was achieved for a period of 8 to 12 weeks. A decrease in dark-plug appearance of greater than 50% was noted in half of the subjects 20 weeks after the second treatment. No pigmentary changes and scarring occurred in any subjects.: Pulsed diode laser proved to be a safe and long-term effective treatment for TS in dark-skinned individuals.
