Nagashima-type palmoplantar keratosis (NPPK) is an autosomal recessive form of palmoplantar keratoderma (PPK), which is caused by mutations in the SERPINB7 gene. NPPK has only been reported in Japanese and Chinese populations. The present study was conducted on 12 unrelated Chinese patients who were clinically predicted to suffer from NPPK. Mutation screening was performed by direct sequencing ...

Background Non-pustular palmoplantar psoriasis (PPP) is chronic and disabling dermatosis. Topical psoralen and solar ultraviolet - A therapy (PUVAsol) is efficacious and safe therapy in psoriasis management. Objective To study the efficacy and adverse clinical effect profile of topical PUVAsol along with methotrexate in PPP. Method This is a prospective, randomized, clinical trial conducted amo...

Micronutrients serve many important functions in our body and altered levels of heavy and trace metals are associated with cutaneous and systemic disorders. Vesicular palmoplantar eczema is an entity whose etiopathogenesis is a mystery. In this prospective case-noncase study blood levels of Zinc and Cadmium in 37 patients of chronic vesiculobullous hand dermatitis were estimated and compared wi...

Acrokeratosis paraneoplastica, or Bazex syndrome, is one of the paraneoplastic syndromes. The characteristic skin lesions include palmoplantar keratoderma, psoriasiform skin lesions, hyperpigmentation, and nail dystrophy. The most common associated neoplasms are squamous cell carcinoma of the upper respiratory tract and other kinds of tumors with cervical lymph node metastasis. A 63-year-old wo...

A case is presented of a female Caucasian patient with chronic peripheral blood eosinophilia and unusual skin manifestations. Within a couple of years, the patient developed multiple hyperkeratotic and hyperpigmented papules and plaques all over the body, palmoplantar keratoderma, pachydermia of acral parts of the body, and generalized pruritus. Generalized lymphadenopathy appeared. Other relev...

A 28-year-old female born to consanguineous parents, presented with progressive palmoplantar keratoderma since the age of six months and a constricting band on right fourth finger of one year duration. There was history of similar complaints being present in two other family members. Associated clinical findings included starfish-shaped cornified plaques on knuckles, resorption of distal phalan...

BACKGROUND High-variable-frequency ultrasound is used as an imaging tool for various cutaneous disorders. We utilized this tool in pachyonychia congenita (PC) patients, who typically present with plantar hyperkeratosis and often severely debilitating pain, compared to patients with epidermolytic palmoplantar keratoderma (EPPK) and mal de Meleda (MDM). OBJECTIVE To ascertain the feasibility of...

A 10-month-old female presented with severe progressive wedge-shaped thickening and discoloration of all twenty nails. Further evaluations revealed palmoplantar keratoderma along with recurrent acral blisters causing residual crusted ulcers which were present during the past six months. Other findings included scalp kinky hair and dental caries. Past medical and family history had remarkable fi...

Twenty years have elapsed since keratin mutations were linked to cutaneous genodermatoses, and we now know that they cause 40 different genetic disorders. In this issue, Wilson et al. have identified KRT6C mutations in patients with focal palmoplantar keratoderma (FPPK), but debate concerning overlapping phenotypes between FPPK and pachyonychia congenita (PC) will continue because only one fami...

administration of multiple cycles of topical and systemic corticosteroid therapy, topical tazarotene, ciclosporin at a dose of 3 mg/kg/d (whose efficacy cannot be adequately evaluated due to treatment interruption after a month because of failure to attend follow-up), and methotrexate at a maximum dose of 20 mg/wk, which the patient continues to receive. Interestingly, despite hypertrophic LP b...
