Case 1. The grandfather, II.3, born in 1889, suffers from lymphatic leukaemia and diabetes. As can be seen in Fig. 2a, the hands show complete anonychia of the thumb, the forefinger, and the middle finger, with nail-bed vestiges present as small ridges on the outer finger edges. The fourth and fifth fingers show the absence of nails in the central part, and two small atrophied nail lamellae on ...

An injury to a finger or toe can result in a collection of blood under the nail plate that if unrelieved can cause extreme discomfort due to pressure. In this case, a 47-year-old man developed a subungual hematoma of the right thumb due to a crush injury. Controlled nail trephination was performed using a uniquely designed drill that penetrated the nail plate without breaching the nail bed. The...

©2018 by Anais Brasileiros de Dermatologia Dear Editor, Onychomatricoma (OM) is a rare benign neoplasm of nail matrix origin. The disease was first described by Baran and Kint in 1992 in a report of three cases.1 In some cases, it may present itself with important nail dystrophy, which makes its diagnosis a challenge. We report a rare case of OM in which we discussed the clinical and dermoscopi...

We hypothesize that nails have an automatic curvature feature and that their flat shape is maintained by the daily upward mechanical forces from the finger/toe pad. Thus, nail deformities, such as pincer nail, spoon nail, and koilonychias, may be caused by an imbalance between these forces and can be treated by controlling these forces. Here, we report the case of a 55-year-old man whose severe...

DEAR EDITOR We describe a 90 year old lady presented with a 2 week history of a nonhealing and bleeding lesion on her right 2nd toe, on a background of one year’s history of chronic infection. The patient had not responded to oral antibiotics and was initially managed with fusidic acid and hydrocortisone acetate cream applied with daily to alternate-day dressings. A history of trauma as the cau...

We undertook this microbiological study of onychomycosis with the aim of determining the prevalence of the various causative agents of onychomycosis in our population. From Jan 1999 to Dec 2001, nail clippings or scrapings were collected from 100 patients clinically suspected of having onychomycosis. They were processed in the Department of Microbiology, Bowring and L. C. Hospital, Bangalore an...

Racehorses are susceptible to underrun heel hoof conformation. often shod with nails placed toward the heel. It is unknown if palmar restrict or alter deformation in a manner that could promote development of conformation over time repeated loading. To determine how addition affects during limb loading, expansion and wall deformations were quantified using rosette strain gauges kinematic marker...

DESCRIPTION A 54-year-old diabetic female patient with type 2 diabetes of 7 years’ duration presented with pain in her big toe. She had previously sustained foot ulceration several times and hence worried for recurrence. On examination she had a laminated, thickened, dark yellow toe nail of an extremely rare structure (figure1). Onychodystrophy, which is a widely used term referring to nail def...
