Pachyonychia congenita (PC) is a rare genodermatosis caused by mutations in any of the four genes KRT6A, KRT6B, KRT16, or KRT17, which can lead to dystrophic, thickened nails and focal palmoplantar keratoderma, among other manifestations. Although classically subdivided into two major variants, PC-1 (Jadassohn-Lewandowski syndrome) and PC-2 (Jackson-Lawler syndrome), according to the localizati...

All member of family referred to our clinic complaining of white nails. Physical examination revealed clinical features of leukonychia totalis and also the presence of sensor ineural hearing loss (SNHL), palmoplantar keratoderma (PPK) and knuckle pads, the four essential criteria for the diagnosis of Bart Pumphrey syndrome. Three generations were affected with variable presentations in ma...

Tegafur is a prodrug of 5-fluorouracil (5-FU) with a similar spectrum of antitumor activity. It is used in the treatment of advanced gastrointestinal neoplasms. Over 5-FU, tegafur has the advantage of oral administration and less hematologic toxicity. Gastrointestinal toxicity is its main dose-limiting factor. The cutaneous adverse effects of tegafur include mucositis, photosensitivity, diffuse...

Although often exhibited at clinical meetings because of its rarity and difficulty in management, its etiology remains unknown. This article presents a review of this enigmatic disorder and subject of debate. Recent focus are a...
