ABSTRACT
Background: The proximal fold is an important part of the nail. It contributes to the formation of the nail plate, and the cuticle forms an impermeable protecting barrier.Objective: To identify the proximal nail fold dermatoses
Methodology: It is a longitudinal, prospective study to know the frequency of proximal nail fold dermatoses in patients residing in the Internal Medicine and Surgery Services at the General Hospital IGSS, regardless of age, sex, or cause of hospitalization, from January 2nd to March 31, 2009. All patients underwent dermatological examination of all the fingernails and toenails with emphasis on the proximal fold.
Results: We studied 255 patients. Only 93 (36.47%) had nails with abnormal proximal fold, 65 (69.89%) were male and 28 (30.10%) female. Internal Medicine cases were 58 (63.36%), and from surgery 35 (37.63%) cases. Dermatoses predominated in the proximal nail fold of the hands. Trauma (micro avulsion injuries of stepfathers, onychophagia pressure, and oximeter) were the most frequent dystrophies 42 cases (45.16%), racial dyschromias 11 (11.82%), cytostatics 6 (6.45%), dermatological diseases 7 (7.52%), systemic diseases 2 (2.15%), and different causes 6 (6.45%).
In toenails, also abnormalities due to micro-trauma of the proximal nail fold were predominant, with 14 cases (15.05%), and other causes such as racial dyschromias 5 (5.37%), cytostatics 1 (1.07%), associated with systemic diseases in 3 ( 3.22%), tumor and infectious causes each one just 1 case (1.07%).
Conclusions: The proximal nail fold may be affected by trauma, or may be associated with other causes. It is therefore important to be aware in order to offer proper treatment.
