Periungual pyogenic granuloma‐like lesions following plaster cast immobilization: a case managed with symptomatic therapy

Onychomadesis and Beau’s lines after cast immobilization: a case report and literature review

“…Including our case, a total of 16 cases of Beau's lines/ onychomadesis associated with cast immobilization following trauma have been reported since 1995 (Table 1) [2][3][4][5][6][7][8]. Notably, nine out of the 16 cases were described in a paper by Tosti et al [6].…”

“…The fractured bone included the radius, metacarpal bones, and distal phalanx. The presence of symptoms during cast wearing was evaluated in 13 patients: ten (76.9 %), including our patient, complained of moderate paresthesia and pain of the immobilized hand, while three (23.1 %) experienced no discomfort during cast immobilization [4][5][6]8]. Cases in which symptoms were not described were considered symptomless, symptoms were reported in 62.5 % of cases.…”

“…All cases of Beau's line/onychomadesis resolved spontaneously. Thirteen cases (81.3 %) were accompanied by periungual PG [4][5][6]8]. Among the cases with PG, two were treated with curettage, topical corticosteroids, and antibiotics, whereas ten resolved spontaneously [5,8].…”

“…Peripheral nerve damage as a result of improper cast application is thought to be an underlying mechanism of Beau's lines/onychomadesis and PG [3,5,6,8]. Denervation affects skin via delayed re-epithelization, decreased vasodilation, and reduced microvascular response [10].…”

“…8]. Von den Fällen mit GP wurden zwei durch Kürettage, topische Kortikosteroiden und Antibiotika behandelt, während zehn Fälle spontan abklangen [5,8]. Unser Patient wurde topisch mit einem β-Blocker behandelt.…”
