SUMMARY Over three successive generations four members of a Sicilian family showed early onset, slowly progressive dystrophy of the finger and toe nails, without any other anomalies or skin signs. Histological examination performed in two patients enabled us to discount lichen planus and other underlying diseases. The hereditary and idiopathic nature of the disease is underlined and a classific...

Nail abnormalities occur frequently in patients with psoriatic arthritis. This study of the finger nails of 46 patients with psoriatic arthritis, 100 nonpsoriatic rheumatism patients, and 100 nonpsoriatic general medical patients was designed to characterise these abnormalities with particular reference to the severity of nail pitting. The results of the study suggest: (1) Onycholysis alone in ...

OBJECTIVE To report clinical features, response to treatment, and long-term follow-up of nail lichen planus in children. DESIGN Retrospective study involving 15 children with nail lichen planus. SETTING Outpatient consultation for nail disorders at the Department of Dermatology of the University of Bologna, Bologna, Italy. PATIENTS OR OTHER PARTICIPANTS We diagnosed nail lichen planus in ...

Autosomal dominant inheritance of a syndrome comprising palmoplantar keratoderma, nail dystrophy, and hereditary motor and sensory neuropathy (HMSN) was observed in three generations of one family. Nail dystrophy affected the toe and fingernails; it was present at birth or developed during early childhood. Palmoplantar keratoderma became apparent in later childhood. Each subject with nail dystr...

Epidermolysis Bullosa Puriginosa is a genetic mechanobullous disease characterized by pruritus, lichenified or nodular prurigo-like lesions, occasional trauma-induced blistering, excoriations, milia, nail dystrophy and albopapuloid lesions that appear at birth or later. Scarring and prurigo are most prominent on the shins. Herein, we report a case with a history of blisters since childhood foll...

Case presentations describing a congenital variation of palmoplantar keratosis are presented. The majority of these conditions are autosomal dominant with associated nail dystrophy. A variant condition is described with little palmar keratosis; however, finger nail and toe nail dystrophy is the most common identifying feature. Gene identification and treatment protocol are presented. Fortunatel...

We describe a fifty-six-year old, Afro-descendent female patient showing dystrophy of her twenty nails and hyperchromic, asymptomatic macule on her face. Histopathological examination of the macule showed vacuolization of the basal layer, melanophages in the superficial dermis and lymphoplasmocytic inflammatory infiltrate. Nail biopsy revealed orthokeratotic hyperkeratosis and lichenoid inflamm...
