TLDR A 4-year-old boy has a rare type of hair loss in a line pattern on his scalp.
A 4-year-old boy was diagnosed with linear alopecia areata, characterized by recurrent patchy hair loss since 3 months of age. The boy also exhibited linear and whorled nevoid hypermelanosis and inflammatory linear verrucous epidermal nevus on his left lower extremity, along with generalized hyperpigmented linear and whorled streaks on the left side of his body. Trichoscopy revealed exclamation mark hairs, broken hairs, and regrowing hairs of different lengths. Despite normal laboratory results for vitamins and minerals, the physical examination confirmed the presence of linear patchy alopecia on the scalp.
