HI Acquired palmoplantar keratoderma in an immunocompromised patient: A case report.

Syphilis, known for its capacity to mimic various diseases, has seen rising incidence, particularly in adolescents, men who have sex with men (MSM), and individuals with HIV. Palmoplantar keratoderma (PPK), a rare manifestation of secondary syphilis, poses diagnostic challenges due to its resemblance to other conditions. We report the case of a 42-year-old man living with HIV presenting with acquired PPK, characterized by hyperkeratotic plaques on the palms and soles, alongside syphilitic roseola.

Dissecting Cellulitis and Alopecic and Aseptic Nodules of the Scalp in Pediatric Patients: An Atypical Age of Presentation Observed in Two Cases.

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.
