BackgroundPincer nail is a nail deformity characterized by transverse overcurvature of the nail plate. Pincer nail can affect a patient's quality of life due to its chronic, recurrent course; however, there have been no clinical studies on the pincer nail condition in Korean patients.ObjectiveThe purpose of this study was to characterize the clinical findings and treatment of pincer nail. In addition, possible etiological factors were considered, and treatment efficacy was evaluated.MethodsThe medical records and clinical photographs of 35 patients (12 males, 23 females) who were diagnosed with pincer nail between August 1, 2005 and July 31, 2009 were studied.ResultsPatient age ranged from 10 to 77 (52.09±17.26) years, and there was a predominance of female (23 out of 35 patients, F:M=2:1). The mean duration of the disorder was 7.45 years (range 0.25~40); 85% had pincer nail for at least 1 year. In addition, 40% had a history of previous treatment and recurrence. There were 82.8% patients with the common type of pincer nails. The most commonly involved nails were both great toenails. Among 35 patients, nail grinding was started in 30 patients, and 25 patients showed clinical improvement with nail grinding. The width index increased and the height index decreased after treatment. The mean follow up period was 8.42 months (range 1~27), and 7 patients showed recurrence after 8.8 months (range 2~20). Among 35 patients, 5 patients were treated with nail extraction with matricectomy, and the symptoms resolved immediately. The mean follow up period was 7.6 months (range 0~19), and recurrence was not observed. Onychomycosis was also present in 37.1% of patients, and itraconazole pulse therapy for 3 months was added.ConclusionThe results of this study demonstrate the clinical features of pincer nail in Korean patients. The findings show that the common type of pincer nail was most common, and nail grinding as a conservative treatment greatly improved pincer nails despite a risk of recurrence. When onychomycosis was also present, oral antifungal therapy added to nail grinding resulted in a more rapid change in nail thickness and clinical improvement.

“…Tumors of the nail apparatus, such as exostosis, implantation cyst, or myxoid pseudocyst, may lead to pincer nails. 16 Pincer nail deformity has also been associated with tinea ungium due to Trichophytum rubrum, 17 ß-blocker (practolol, 18 acebutolol, 19 metoprolol 20 ) usage, arteriovenous fistula placement in the forearm, 21 and metastasizing adenocarcinoma of the sigmoid colon. 22 The most frequent cause of acquired pincer nails of toes is foot deformity with deviation of the phalanges, often a result of ill-fitting shoes.…”

“…Wśród innych przyczyn paznokci pincetowatych wymienia się choroby układowe, wytworzenie przetoki tętniczo--żylnej (arteriovenous fistula -AVF) oraz stosowanie niektórych leków, m.in. β-adrenolityków (praktolol, acebutolol) [6][7][8][9][10][11][12]. Przypadki paznokci pincetowatych w przebiegu tocznia rumieniowatego układowego (systemic lupus erythematosus -SLE) opisano w latach 2005 [13] i 2016 [14] oraz ostatnio -w styczniu 2017 r.

Introduction. Pincer nail deformity due to systemic lupus erythematosus is a rare phenomenon and only three cases have been reported to date. Objective. To present a case of pincer nails in a systemic lupus erythematosus patient and a brief review of the literature. Case report. A 15-year-old girl presented with multiple painful pincer nail deformities, fever and joint pain of 6 months duration. On evaluation and laboratory investigations the patient fulfilled the criteria for systemic lupus erythematosus. Systemic treatment with glucocorticosteroids and antimalarials led to resolution of fever and joint pain but nail deformities did not improve. Conclusions. Pincer nail may be an early and important sign of systemic lupus erythematosus in certain patients. STRESZCZENIEWprowadzenie. Deformacja w postaci paznokci pincetowatych w przebiegu tocznia rumieniowatego układowego jest zjawiskiem rzadkim. Dotychczas w piśmiennictwie odnotowano zaledwie trzy takie przypadki. Cel pracy. Przedstawienie przypadku paznokci pincetowatych u pacjentki z toczniem rumieniowatym układowym oraz krótki przegląd piśmiennictwa. Opis przypadku. Piętnastoletnia pacjentka zgłosiła się z licznymi bolesnymi zniekształceniami w postaci paznokci pincetowatych, gorączką oraz bólami stawowymi, które utrzymywały się od 6 miesięcy. Badanie przedmiotowe i wyniki badań laboratoryjnych były zgodne z kryteriami diagnostycznymi tocznia rumieniowatego układowego. Po wdrożeniu leczenia ogólnoustrojowego glikokortykosteroidami i lekami przeciwmalarycznymi gorączka i ból stawów ustąpiły, jednak nie uzyskano poprawy stanu paznokci. Wnioski. Paznokcie pincetowate mogą być wczesnym i istotnym objawem tocznia rumieniowatego układowego u niektórych pacjentów.Key words: antimalarials, pincer nails, prednisolone, systemic lupus erythematosus. Słowa kluczowe: leki przeciwmalaryczne, paznokcie pincetowate, prednizolon, toczeń rumieniowaty układowy. INTRODUCTIONPincer nail (also known as omega nail, trumpet nail, convoluted nail, and unguis constringens) is the transverse over-curvature which progressively pinches the nail bed distally [1,2]. It increases in a proximal to distal direction, giving a trumpet appearance. It is more commonly observed on toes than on fingers [2]. It can be hereditary or acquired. An ill-fitting shoe is the most frequent acquired cause [3]. Different dermatoses, such as psoriasis (the most common dermatologic cause), tumors of the nail apparatus and tinea unguium can lead to pincer nail deformity [4,5]. Systemic diseases, placement of arteriovenous fistula (AVF) and use of medications, i.e. β-blockers such as practolol and acebutolol, can lead to pincer nail deformity [6][7][8][9][10][11][12]. Pincer nails associated with systemic lupus erythematosus (SLE) were described in 2005 [13], in 2016 [14] and recently in January, 2017 [15]; but to our knowledge, an isolated finding of pincer nails as the only presenting cutaneous manifestation of SLE has not been reported.
