This study reports on monozygotic twin sisters with palmoplantar keratoderma and growth hormone deficiency. Researchers speculate a shared genetic mutation may cause both conditions, highlighting a rare syndromic association.
Area of Science:
- Genetics
- Endocrinology
- Dermatology
Background:
- Palmoplantar keratoderma (PPK) encompasses diverse disorders of palm and sole thickening, classified as focal or diffuse, and can be acquired or hereditary.
- Syndromic associations with PPK are documented across various inheritance patterns, though rare manifestations include skin/nail changes, malignancy predisposition, skeletal deformities, dwarfism, and enamel abnormalities.
Observation:
- This case report details monozygotic twin sisters presenting with palmoplantar keratoderma.
- Both twin sisters were also diagnosed with growth hormone deficiency.
Findings:
- The co-occurrence of palmoplantar keratoderma and growth hormone deficiency in monozygotic twins suggests a potential shared underlying etiology.
- A common genetic mutation is hypothesized to underlie these two distinct clinical presentations.
Implications:
- This case may offer insights into the genetic basis of rare PPK syndromes and growth hormone deficiency.
- Further research into shared genetic factors could elucidate novel pathways involved in both dermatological and endocrine development.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
