palmarplantar

Palmarplantar is an adjective used in anatomy and medicine to describe something related to or affecting the palmar (palm) aspect of the hand and the plantar (sole) aspect of the foot. The term is formed from the Latin palma (palm) and planta (sole) and is often encountered in descriptive phrases that reference the two corresponding surfaces.

In anatomical usage, palmar-plantar refers to features, textures, or regions that occur on both the palmar and plantar surfaces, or to comparisons between these surfaces. For example, descriptions of skin, nerves, or vascular patterns may note palmar-plantar symmetry or convergence.

In clinical contexts, palmarplantar may be used to describe diseases or conditions that affect both the palms and soles. A well-known example is hand-foot syndrome, medically termed palmar-plantar erythrodysesthesia, a side effect of some chemotherapies that presents with redness, swelling, or pain in both sites, typically on the palms and soles. Palmar-plantar keratoderma is another dermatological term used for thickened palmar and plantar skin.

Usage varies by discipline and author; some sources favor the hyphenated form palmar-plantar, others use palmar plantar or simply palmar/plantar with contextual cues. Overall, the term serves as a concise descriptor for dual-location anatomy or pathology involving the palms and soles.
