Acral localized acquired cutis laxa: Report of a case associated with inflammatory arthritis
Bibliographic record
Abstract
To the Editor: Acral localized acquired cutis laxa (ALACL) is a distinct variant of acquired cutis laxa characterized by loose redundant skin primarily confined to the distal extremities. It is often associated with signs or symptoms of a preceding inflammatory dermatosis, such as urticaria, erythema, swelling, or pruritus. Disease associations include multiple myeloma, idiopathic urticaria, Raynaud phenomenon, and rheumatoid arthritis. We report a case associated with inflammatory arthritis in childhood. A 41-year-old woman with a history of polyarticular juvenile idiopathic arthritis diagnosed at age 3 presented with asymptomatic loose, pendulous skin confined to her volar finger pads and toes. She noted the onset of loose skin at age 6 and described ill-defined erythema, warmth, and pruritus of her hands that preceded the development of the skin changes. The degree of skin laxity remained stable since childhood. There was no history of urticaria. Family history was relevant for a paternal grandfather with rheumatoid arthritis. On examination, there was loose redundant skin on the finger pads bilaterally that gave them a flat rounded appearance (Fig 1). The volar finger pads were soft on palpation and the skin remained depressed when pressure was applied, giving them an appearance that has been described as “chewing gum-like.”1Martin L. Requena L.

Acrolocalized acquired cutis laxa.Br J Dermatol. 1996; 134: 973-976Crossref PubMed Scopus (25) Google Scholar The plantar surface of the toes had similar skin changes, although less striking. Facial appearance was normal and did not show advanced aging. Rheumatoid factor and anticyclic citrullinated peptide were negative. Plain radiography of the hands showed stable minor erosive changes. Skin biopsy samples were obtained from the volar surface of the left middle finger and unaffected skin on the left upper arm. The specimen from the left middle finger showed a marked decrease in elastic fibers. A neutrophilic inflammatory infiltrate was not identified, as was observed previously in ALACL.2Fisher B.K.

Ultrastructural examination of the specimen from the left middle finger showed elastic fibers fragmented into multiple electron dense pieces (Fig 2).

Given the consistent localization and disease associations, we propose that ALACL be recognized as a distinct entity within the spectrum of acquired cutis laxa.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
