Localized Cutaneous Mucinosis After Joint Replacement

Plaque‐like cutaneous mucinosis after joint replacement

“…Like the cases described by Haught et al, 1 in our patient, the skin involvement appeared months after surgery and was not associated with prosthesis dysfunction. Plaque‐like cutaneous mucinoses may appear in extrathoracic locations 4 and may be associated with monoclonal gammopathy 5,6 .…”

“…Localized cutaneous mucinosis may arise after joint replacement 1 . We report a case of plaque‐like cutaneous mucinosis associated with monoclonal gammopathy that developed months after knee replacement.…”

“…Cutaneous mucinoses represent a heterogeneous group of diseases whose main characteristic is mucin deposition in the skin 2 . Haught et al reported two examples of atypical lichen myxedematosus that appeared in the months following surgery in patients with knee osteoarthritis 1 . One of them had mildly erythematous papules and the other a yellowish plaque 1 .…”

Focal cutaneous mucinosis after knee replacement: A rare entity successfully treated with intralesional polidocanol

“…However, the pathogenesis of cutaneous mucin deposition after joint replacement surgery is still unclear, although several mechanisms have been considered: increased secretion of hyaluronic acid from osteoarthritic joints, local reactive process to foreign body (prosthesis), accidental implantation of the synovial cells at the surgical site, or traumatic damage of the lymphatic system responsible for the drainage and absorption of the synovial fluid 2, 3, 4, 8…”

“…There is a paucity of published cases of cutaneous mucinosis developing adjacent to replaced joints 3, 4. Apart from presenting our patient, we review the literature, propose the pathogenesis, and suggest treatment for this unusual cutaneous presentation.…”
