Palmoplantar keratoderma-deafness syndrome is a keratinization disorder characterized by focal or diffuse palmoplantar keratoderma. A patchy distribution is observed with accentuation on the thenars, hypothenars and the arches of the feet. The disease becomes apparent in infancy and is associated with sensorineural hearing loss that shows a variable age of onset. Due to genetic and clinical similarities, it has been proposed that palmoplantar keratoderma-deafness syndrome, knuckle pads-leukonychia-sensorineural deafness-palmoplantar hyperkeratosis syndrome and keratoderma hereditarium mutilans may represent variants of one broad disorder of syndromic deafness with heterogeneous phenotype. The disease is transmitted in an autosomal dominant manner with incomplete penetrance. |

Hypotrichosis-osteolysis-periodontitis-palmoplantar keratoderma syndrome is an extremely rare ectodermal dysplasia syndrome characterized by hypotrichosis universalis with mild to severe scarring alopecia, acro-osteolysis, onychogryphosis, thin and tapered fingertips, periodontitis and caries leading to premature teeth loss, linear or reticular palmoplantar keratoderma and erythematous, scaling, psoriasis-like skin lesions on arms and legs. Lingua plicata and ventricular tachycardia have also been observed. |

Wooly hair-palmoplantar keratoderma syndrome is a very rare, hereditary epidermal disorder characterized by hypotrichosis/wooly scalp hair, sparse body hair, eyelashes and eyebrows, leukonychia, and striate palmoplantar keratoderma (more severe on the soles than the palms), which progressively worsens with age. Pseudo ainhum of the fifth toes was also reported. Although wooly hair-palmoplantar keratoderma syndrome shares clinical similarities with both Naxos disease and Carvajal syndrome, cardiomyopathy is notably absent. |

Striate palmoplantar keratoderma is an isolated, focal, hereditary palmoplantar keratoderma characterized by linear hyperkeratosis along the flexor aspect of the fingers and on palms, as well as focal hyperkeratosis of the plantar skin. Patients present with painful thickening of the skin on palms and soles, with occasional fissuring, blistering and hyperhidrosis. Rarely, hyperkeratosis on other areas may be seen (knees, dorsal aspects of the digits). Histopathologically, widened intercellular spaces between keratinocytes are observed. |

Focal palmoplantar and gingival keratoderma is a very rare form of focal palmoplantar keratoderma characterized by painful circumscribed hyperkeratotic lesions on weight-bearing areas of soles, moderate focal hyperkeratosis of palmar pressure-related areas and an asymptomatic leukokeratosis confined to labial- and lingual- attached gingiva. Additional occasional features may include hyperhidrosis, follicular keratosis and extended oral mucosa involvement. |

Nail and teeth abnormalities-marginal palmoplantar keratoderma-oral hyperpigmentation syndrome is a rare genetic ectodermal dysplasia syndrome characterized by short stature, nail dystrophy and/or nail loss, oral mucosa and/or tongue hyperpigmentation, dentition abnormalities (delayed teeth eruption, hypodontia, enamel hypoplasia), keratoderma on the margins of the palms and soles and focal hyperkeratosis on the dorsum of the hands and feet. Additionally, dysphagia with esophageal strictures, sensorineural deafness, bronchial asthma and severe iron-deficiency anemia have been observed. |
