TLDR A 10-year-old boy was diagnosed with a rare scalp condition causing hair loss and treated with a topical cream.
A 10-year-old boy presented with a localized patch of hair loss on the scalp, first noticed a few months after birth. The lesion showed minimal growth over time and had occasional redness and discharge, controlled with topical treatments. Examination revealed grouped comedonal lesions over a patch of partial alopecia on the occipital scalp, with no inflammation. A biopsy showed deep invaginations of the epidermis filled with keratin, without significant perifollicular inflammatory infiltrate. An atypical nevus comedonicus was diagnosed, and the patient was started on topical tretinoin 0.05% and is under follow-up.
