Paired Hairs

Paired Hairs Abstract To the Editor.— The publication of papers on trichostasis spinulosa and pili bifurcati in the Archives (108:403, 1973) prompts me to report another variation in hair growth. Report of a Case A 44-year-old black man, in good general health, was examined because of scrotal neurodeumatitis. His chest, axillary, and pubic hairs were noted to emerge from their follicular openings two by two (Figure). His scalp, beard, and other body hairs appeared normal each emerging singly.Paired hairs on chest.The peculiar distribution of his hairs could have several explanations. Trichostasis spinulosa results from the retention of telogen hairs in a follicle during the growth of a new anagen hair. Pili bifurcati and pili multigemini result from a composite papilla that forms several hair shafts that are more or less separated. Closely adjacent independent follicles can share one opening. Grouped hairs are normal for some mammals,1 hair growth in pairs References 1.
