An unusual case of folliculitis spinulosa decalvans.
We report the case of a 24-year-old man who presented with pustules, atrophic scars, and alopecia on the scalp, along with follicular keratotic papules on the cheeks, chest, abdomen, back, lateral upper arms, thighs, and axillae, of 6 years' duration. A diagnosis of folliculitis spinulosa decalvans (FSD) was made based on the clinical manifestation and histopathological findings. Dental examination also revealed dental anomalies and a fissured tongue, which are not known to be related to FSD. We provide an overview of the characteristic findings of FSD as well as a review of previously reported cases.
