Keratosis punctata palmoplantaris (KPPP) is a rare genodermatosis with an autosomal-dominant pattern of inheritance. We report the case of a 61-year-old woman who presented with a long history of multiple symptomatic hyperkeratotic papules on the palms and soles. In addition, we review the literature and present the current classification of the heterogeneous group of punctate palmoplantar keratoses, the cutaneous and histologic findings, the differential diagnosis, the possible association with various anomalies including malignancies, and the various treatment options.

Article Synopsis
- Genodermatoses are rare genetic skin disorders that can severely affect an individual's health and may result in early mortality due to their multiorgan involvement.* -
- A systematic review of the literature focused on X-linked genodermatoses in pediatric males highlighted key conditions grouped by keratinization, pigmentation, and inflammatory issues, providing examples like dyskeratosis congenita and ichthyosis.* -
- The review emphasizes the significance of genetic diagnosis and outlines the current landscape of clinical trials involving orphan drugs and gene therapy for these disorders, linking clinical assessments to molecular testing.*

Article Synopsis
- - The study explores various phenotypes of non-inflammatory palmar and plantar keratoderma (PPK) prevalent in Sub-Saharan African patients, proposing they might collectively be known as "African Acral Keratoderma" (AAK).
- - A review of 42 patients over 11 years revealed that most displayed mixed forms of keratoderma, with a significant proportion (40%) having familial histories, suggesting a potential genetic link.
- - Findings support the AAK concept, with the majority receiving topical treatments, and the rare condition "ainhum" managed surgically.

Conradi-Hünermann-Happle syndrome (CHHS) is a rare genodermatosis resulting from mutations in the EBP (emopamil binding protein) gene. Dermatologic manifestations may include cicatricial alopecia, ichthyosis, follicular atrophoderma, pigmentary abnormalities, and nail dystrophy. In addition to genetic testing and clinical findings, trichoscopic findings may aid in the diagnosis.
