Pachydermodactyly associated with extensive computer gaming: A report of three cases

Abstract

Pachydermodactyly is an uncommon, progressive, nontender thickening of the fingers with prominent involvement of the proximal interphalangeal joints. Pachydermodactyly mimics inflammatory arthritis but plain film radiography is normal in this condition. Pachydermodactyly has been previously described in workers performing manual labor. Mechanical stimulation has been identified as a predisposing factor in the majority of cases. We present three cases in adolescent males arising in association with excessive computer gaming.

Gamer's nodulesBRIEF REPORT

“…They have also been reported with repetitive pressure associated with religious practices and are referred to as “prayer nodules”, 3 occurring on the forehead, dorsum of feet, and lateral malleoli. Gaming specific nodules have been previously described including knuckle pads 4 and pachydermodactyly 5 . These were noted on the hands and over specific joints (distal interphalangeal and proximal interphalangeal joints).…”

“…They have also been reported with repetitive pressure associated with religious practices and are referred to as "prayer nodules", 3 and pachydermodactyly. 5 These were noted on the hands and over specific joints (distal interphalangeal and proximal interphalangeal joints). Treatments described include avoiding repetitive friction to the affected area, keratolytics as well as topical and intralesional steroid.…”

Pachydermodactyly: Soft Tissue Enlargement of the Fingers in a Teenager

“…Intralesional glucocorticoids, surgery, and analogs of a tryptophan metabolite (tranilast) have been used with relative improvement [ 1 , 10 ]. A spontaneous remission can present after stopping physical stress [ 11 ]. In the present case, our patient was treated with intralesional triamcinolone with mild improvement.…”

Pachidermodaktilija: Priežastys, Diagnostika, Gydymas

“…Manoma, kad viena iš priežasčių yra nuolatinis ir nenutrūkstamas minkštųjų audinių dirginimas ir traumavimas proksimalinių interfalanginių sąnarių srityje [3]. Ši liga dažnai diagnozuojama asmenims, kurie savo kasdienėje veikloje atlieka daug pasikartojančių judesių ar žalingų veiksmų su pirštais -muzikantams, sportininkams, dirbantiems kompiuteriu, maisto pramonės darbuotojams [5,7,8]. Pacientai, turintys neuropsichiatrinių sutrikimų, dažnai ,,traškina", trina savo pirštus, todėl esant tikams, obsesiniam kompulsiniam ar Aspergerio sindromams gali išsivystyti pachidermodaktilija [5,9].…”
