    The document described a case study of a 15-year-old Japanese girl with juvenile hypothyroidism who exhibited symptoms of hypertrichosis and hyperkeratosis on her back and the extensor aspects of her upper arms. The study noted the presence of rolled hairs beneath a thin translucent horny layer, which were caused by a follicular plug of keratin that inhibited the growth of miniature hairs.
