Localized Darier's disease (DD) is a rare variant of DD. The disease is characterized by multiple hyperkeratotic papules in a unilateral, linear, zosteriform or Blaschkoid distribution with the histological features of classical DD. Unlike DD, which presents as a generalized condition, localized DD lacks family history and other clinical findings suggestive of DD such as distinctive nail abnormalities and keratotic papules on the palms and soles. Herein, we describe a case of localized DD in a 31-year old Korean man on the perianal area that was treated with topical retinoid cream.

Koilonychia is dystrophy characterized by eversion of the marginal portion of the nail. As a result, the central portion of the nail is concave. It has been associated with systemic or skin-related conditions. Hereditary koilonychia is inherited as an autosomal dominant trait. Koilonychia can also be caused by exogenous factors such as certain toxic chemicals or repeated mechanical trauma. In this case, koilonychia on the fingernail of the left thumb was caused by repeated trauma resulting from continuous suction since birth. Herein, we report a rare case of koilonychia induced by habitual thumbsucking.

A congenital ectopic nail is a rare anomaly and usually manifests itself as a small abnormal nail appearing alongside the normal nail. In most of the cases, abnormal nails have been found on the palmar surface of the fifth finger. The pathogenesis of the ectopic nail remains unclear. It has been postulated to be a kind of polydactyly or generation from stray germ cell or inoculation of the nail matrix after trauma. We observed a case of a 5-month-old boy with congenital ectopic toenail on the right second toe. The ectopic toenail was removed by surgical excision and the histopathological finding was consistent with ectopic toenail. We report a case of congenital ectopic toenail on the right second toe of a 5-month-old boy.

The important prerequisite for treatrnent of onychomycosis is the removal of as rnuch fungus-infected nail material as possible. Nincty-five patients with anychomycosis were treated with using urea preparations under occlusive dressings. The urea preparations were quite successful in maceraing the nail plate from the nail bed, allowing the easy removaI of diseased nails in all cases except one. The urea preparations removed only abnormal nail. Completely normal nail was unaffected. After nail avulsion, 95 patients were treated for 6 months with combination clotrimazole and ketoconazcile(group A), or with clotrimazole only(group B). Of the 38 patients in group A who complcted the treatment, 25(65.8%) were cured 6 months later by clinical and mycological criteria, compared to 20(47.6%) of 42 patieries in group B.

Pterygium inversum unguis (PIU) is a rare nail abnormality in which the distal nail bed adheres to the ventral surface of the nail plate, with obliteration of the distal groove. Because of the rarity of this condition, its exact origin is unknown. This disorder can be either congenital or acquired, with or without a family history. The acquired forms may be idiopathic or secondary to systemic connective tissue diseases or other causes such as stroke, neurofibromatosis, leprosy, or the use of nail fortifiers. We present an unusual case of acquired idiopathic PIU of the 10 fingernails in a 22-year-old man.

Pachyonychia congenita (PC) is a rare autosomal-dominant ectodermal dysplasia, which is characterized by hypertrophic nail dystrophy, diffuse or focal symmetrical hyperkeratosis of the palms and soles, oral leukokeratosis, follicular keratosis on the extensor surfaces of the extremities, and other ectodermal defects. However, the variable degree of gene mutation may result in nail abnormalities alone. The nail changes presented in our patient are the only clinical manifestation. Hypertrophic nail dystrophy and yellowish discoloration, without involving any other organs, were shown in both mother and baby since birth. To the best of our knowledge, the case of PC affecting only the nails has never been reported in Korea before. Herein, we report monosymptomatic form of PC, which is notable for its rareness and unique pattern, distinct from previously reported cases.
