“…The commonest reported variety are bone-located epidermoid cysts associated with osteolysis: they are usually painful, may cause swelling of the terminal phalanx and can frequently be detected on X-ray examination [4][5][6][7]: in our opinion, they are best referred to as epidermoid implantation cysts. The other type of subungual epidermoid cysts has hitherto been described in normal or just clubbing nails as SEI [1][2][3]: in these cases there is no bone involvement.…”

Eight cases of subungual epidermoid cysts associated with distinctive nail abnormalities are reported. Toes and thumbs were the most frequent sites affected by this probably not rare condition. The most striking clinical features were subungual hyperkeratosis associated with shortened and dystrophic nail plate. A history of trauma was frequent. In all cases, the nail biopsy showed marked hyperplasia of the nail bed and epidermoid cysts in the dermis. The authors propose a new classification for subungual epidermoid cysts.

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.
