Alopecic and aseptic nodules of the scalp (AANS) is a rare entity, etiology of which is already unknown. It consists of a few dome-shaped, skin-colored nodules associated with nonscarring alopecia. They are usually located in the upper part of the occiput and surrounded by normal scalp. Most of the times, a biopsy is performed to make an accurate diagnosis. AANS have a good prognosis and even can resolve spontaneously. We present a new case of this entity with the description of trichoscopic and ultrasonographic findings that have recently been reported. These noninvasive techniques are useful for the diagnosis and could replace histological examination in the near future.

Dissecting cellulitis of the scalp (DCS) is a rare inflammatory condition that progresses from papules and pustules to nodules and abscesses, ultimately leading to cicatricial alopecia. It primarily affects African men between the ages of 15 and 62, with exceptionally low prevalence in children. A milder form, described as "alopecic and aseptic nodules of the scalp" (AANS), presents as aseptic nodules associated with non-scarring alopecia and has a good prognosis.

Article Synopsis
- Alopecic and aseptic nodules of the scalp (AANS) and dissecting cellulitis of the scalp (DCS) are rare scalp conditions primarily affecting young men.
- A 9-year-old boy showed signs of these conditions with chronically relapsing, sterile, and partially scarring nodules on his scalp and face for six years.
- His histopathological examination revealed unique mixed inflammation patterns, suggesting this case could represent a new variant of AANS and DCS due to its early onset and facial involvement.
