Keratosis palmoplantaris, periodontopathy,onychogryposis with mutation in CTSC gene, also called Haim-Munk syndrome, is a genetic, autosomal recessive inherited disorder characterized mainly by palmoplantar hyperkeratosis and periodontitis.

Occurrence/Epidemiology
This section has been translated automatically.

HMS is rare, with fewer than 100 cases described in the literature to date. Most of the patients described are descendants of a few consanguineous families from a religious isolate in Cochin (India).

Etiopathogenesis
This section has been translated automatically.

HMS is caused by mutations in the CTSC gene, which are inherited in an autosomal recessive manner. In many cases, the affected persons are descendants of a consanguineous family from India.

Manifestation
This section has been translated automatically.

Keratosis usually develops in affected individuals between the ages of 1 and 5.

Clinical features
This section has been translated automatically.

Haim-Munk syndrome (HMS) is characterized by palmoplantar hyperkeratosis, severe and early-onset periodontitis, onychogryposis, pes planus, arachnodactyly and acroosteolysis. in addition, scaly skin areas occur on the knees, shins, elbows and back of the hands. Deformities of the fingers (conical, tapered phalangeal ends and claw-like volar curvature) are characteristic. Periodontitis is severe and has an early onset, affecting even the deciduous teeth. It occurs in the accompaniment of gingivitis and alveolar bone resorption. Patients are very susceptible to infections

Diagnosis
This section has been translated automatically.

The diagnosis is based on the clinical findings and can be confirmed by the detection of the causative mutations. Differential diagnoses include other diseases with palmoplantar hyperkeratosis and prepubertal periodontitis.

Therapy
This section has been translated automatically.

Treatment of skin symptoms requires topical emollients, keratolytics (including salicylates and urea), and oral retinoids (acitretin, etretinate, and isotretinoin). Periodontitis in HMS is usually unresponsive to traditional therapies for periodontitis. Extraction of deciduous teeth in combination with oral antibiotics and professional dental cleaning may be helpful. Synovectomy reduced inflammation in destructive arthritis, but may result in limited joint mobility.
