Degenerative Collagenous Plaque of the Hand (Linear Keratoelastoidosis of the Hands)

Abstract

Clinical and histological features of three examples of degenerative collagenous plaques of the hands in Indian housewives have been described in detail in order to focus attention on a hitherto uncommon entity. Household trauma has been incriminated as the precipitating or a triggering factor in these cases.

Unusual and recently described cutaneous atrophic disorders

“…Thus, while nodular clinically, there is degeneration of dermal elastic fibers histologically 27,28 . Degenerative collagenous plaques of the hands, a variant of acrokeratoelastoidosis, appears virtually identical histologically with degenerated collagen as well as elastin 32 . Most cases are asymptomatic and pose mainly cosmetic abnormality, although there may be fissuring, which may be troublesome.…”

“…27,28 Degenerative collagenous plaques of the hands, a variant of acrokeratoelastoidosis, appears virtually identical histologically with degenerated collagen as well as elastin. 32 Most cases are asymptomatic and pose mainly cosmetic abnormality, although there may be fissuring, which may be troublesome. While most treatment efforts have been unsuccessful, erbium: yttrium-aluminium-garnet (Er:YAG) laser vaporization has shown some beneficial effect.…”

Acquired disorders of elastic tissue: part I. increased elastic tissue and solar elastotic syndromes

“…166,168 Men are more commonly affected than women, and the majority of but not all reported cases have been in white patients. 169 Etiology and pathogenesis. It has been suggested that chronic sun exposure and manual labor that involves chronic pressure or repeated trauma may be contributing factors, although these findings have not been universally reported among affected persons.…”

“…168 A lymphocytic infiltrate in the papillary dermis has also been reported. 169 Associated conditions. Keratoelastoidosis marginalis has not been associated with systemic abnormalities.…”

Keratoelastoidosis Marginalis

“…2,[4][5][6][7][8][9] The youngest patient reported to date is a female in her early 40s. 6 Both males and females are affected, but males are reportedly more commonly affected. Although reported in nonCaucasians, most cases of KM have been reported in faircomplexioned individuals supporting the role of actinic damage as a possible etiology.…”
