Twenty Nail Dystrophy (TND) is a rare acquired idiopathic nail dystrophy characterized by excess longitudinal ridging, distal notching, splitting, loss of nail luster and thinning of nail plates that may affect 1 to 20 nails. It occurs as a common manifestation of various dermatoses affecting the nail unit like lichen planus, psoriasis, atopic dermatitis, onychomycosis, vitiligo and alopecia ar...

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 ...

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.

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...
