TLDR A 19-year-old man had a rare skin condition on one side of his face that looked like another skin disease.
A 19-year-old man presented with a unique case of unilateral keratosis pilaris atrophicans faciei (KPAF), which clinically mimicked follicular mucinosis. KPAF, a condition involving follicular hyperkeratosis, inflammation, and scarring, typically affects the lateral eyebrows within months of birth. This case was notable as unilateral presentation of KPAF had not been previously reported, although unilateral atrophoderma vermiculata (AV) had been documented. The report highlighted the distinct characteristics and differential diagnosis of KPAF, AV, and keratosis follicularis spinulosa decalvans (KFSD), which involves the scalp and leads to scarring alopecia.
