Short answer · Medically reviewed summary · Last updated: 2026-05-08
Palmoplantar Keratoderma (PPK) is a heterogeneous group of disorders characterized by abnormal thickening of the skin on the palms and soles, often referred to as keratosis palmoplantaris. Because these conditions vary widely in their genetic origins and clinical presentation, they are frequently categorized by their inheritance patterns or associated systemic symptoms rather than a single universal name. What are the common synonyms for Palmoplantar Keratoderma? Medical literature often uses Palmoplantar Keratoderma interchangeably with the term "keratosis palmoplantaris." Depending on the specific clinical subtype, you may encounter terms such as hereditary palmoplantar keratoderma, diffuse palmoplantar keratoderma, or focal palmoplantar keratoderma.

Palmoplantar Keratoderma (PPK) is a heterogeneous group of disorders characterized by abnormal thickening of the skin on the palms and soles, often referred to as keratosis palmoplantaris. Because these conditions vary widely in their genetic origins and clinical presentation, they are frequently categorized by their inheritance patterns or associated systemic symptoms rather than a single universal name.
What are the common synonyms for Palmoplantar Keratoderma?
Medical literature often uses Palmoplantar Keratoderma interchangeably with the term "keratosis palmoplantaris." Depending on the specific clinical subtype, you may encounter terms such as hereditary palmoplantar keratoderma, diffuse palmoplantar keratoderma, or focal palmoplantar keratoderma. In older dermatological texts, the condition was sometimes described using descriptive terms related to the appearance of the skin, such as "tylosis" or "mal de Meleda."
Why does Palmoplantar Keratoderma have so many different names?
The complexity of Palmoplantar Keratoderma nomenclature stems from the fact that it is not a single disease, but a collection of over 100 distinct genetic and acquired conditions. Historically, clinicians named these conditions based on the geographic region where a family was first studied (e.g., Mal de Meleda) or the specific clinical pattern of skin thickening. Modern classification, such as that found in OMIM (Online Mendelian Inheritance in Man), now prefers grouping Palmoplantar Keratoderma by the underlying gene mutation or the specific pattern of inheritance (autosomal dominant vs. recessive).
How is Palmoplantar Keratoderma classified in medical systems?
Official medical databases categorize Palmoplantar Keratoderma using specific codes to ensure diagnostic accuracy:
- Orphanet: Uses the ORPHA code 485 for hereditary palmoplantar keratoderma.
- ICD-10: Classified under Q82.8 (Other specified congenital malformations of skin) or L85.1 (Acquired keratosis palmoplantaris).
- OMIM: Lists dozens of distinct entries for various genetic forms of Palmoplantar Keratoderma, each with unique identification numbers.
