Causes of Residual Pain after Open Excision of Wrist Ganglion / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to verify the relationship between the residual pain and preoperative carpal instability, as well as the generalized laxity after open excision of wrist ganglion. MATERIALS AND METHODS: Sixty-four patients, who received open excision of wrist ganglion, were retrospectively enrolled. The relationships between residual pain (visual analogue scale, VAS) and postoperative function (quick disabilities of the arm, shoulder and hand, quick-DASH), between residual pain and preoperative carpal instability, as well as generalized laxity were evaluated. The carpal instability was assessed from radiologic carpal instability (dorsal intercalated segment instability and volar intercalated segment instability) and Watson scaphoid shift test. The generalized laxity was assessed by the Beighton hypermobility score. RESULTS: Pain VAS and quick-DASH were significantly improved postoperatively. There was a significant difference in postoperative residual pain between those with (n=6) and without carpal instability (n=58) (+: 2.50±1.76 vs. −: 1.18±1.24; p=0.022), but there was no correlation between carpal instability and postoperative quick-DASH. Both postoperative residual pain and quick-DASH had no correlation with generalized laxity (n=18). CONCLUSION: Patients with preoperative carpal instability had greater residual pain after excision of wrist ganglion than those without.

A Case of Autosomal Recessive Type 2 Pseudoxanthoma Elasticum Presenting Generalized Cutaneous Laxity / 대한피부과학회지

Pseudoxanthoma elasticum is a rare, heritable disorder of elastic fibers characterized by yellowish, coalescing papules on the loose and wrinkled flexural skin. An 18-year-old man presented cutis laxa-like marked wrinkling on the axillae, trunk and thighs for about 10 years. There was no similar skin lesion on his family members and no other systemic involvement was found. Histopathological examination of the abdomen revealed fragmentation and calcification of elastic fibers in the middle and lower dermis. Von Kossa staining showed calcium deposition along the altered elastic fibers. Herein, we report a rare case of autosomal recessive pseudoxanthoma elasticum presenting generalized cutaneous laxity.

A Case of Pseudoxanthoma Elasticum Clinically Mimicking Cutis Laxa / 대한피부과학회지

Pseudoxanthoma elasticum is a rare, heritable, systemic disease of connective tissue characterized by degeneration of elastic fiber and mainly affects the skin, eye and blood vessels. We report a case of pseudoxanthoma elasticum mimicking cutis laxa. She had a generalized laxity of the skin for about 30 years. There were similar skin lesions in her sister. No other systemic involvement was found. Histopathologic examination revealed clumping, fragmentation and calcification of elastic fibers in the dermis.
