Etiology and treatment of the so-called mucous cyst of the finger

Efficacy and safety of sclerotherapy for digital mucous cysts

“…The recurrence rate in this study was 8%, which is lower than previous reports of recurrence after surgical excision (3)(4)(5). One patient (patient 10) maintained disease-free status for 46 months after a single injection of sclerosant, despite a history of previous excision treatment failures.…”

“…Some researchers believe that DMCs arise as a result of joint fluid leaking from the DIPJ (3,4,12). Connections between cysts and DIPJ can be demonstrated by the appearance of dye in the cyst after injection of dye into the joint, the pathology of which can be successfully treated by identification and repair of the joint fluid leak (8).…”

“…In cases of simple puncture and drainage the success rate is 72% (15), and cryotherapy of cysts has a curative rate of 56-86% (16,17). Surgical excision of cysts has a reported success rate of 88% (5) to 100% (3,4). Although conventional surgical excision seems to be an effective therapeutic modality, surgery results in considerable variation in recurrence rates depending on the technique used.…”

“…Recently, infrared coagulation was reported to be an effective alternative treatment modality for DMCs (2). Surgery, a conventional and typical treatment method, has been described as one of the most effective treatment (3)(4)(5), but there is considerable variation in recurrence rate depending on the technique used. In addition, surgical intervention requires a great deal of time, surgical expertise and postoperative wound-healing process, and may result in scars that limit joint movement (1,(6)(7)(8)(9).…”

The rhomboid flap: a simple technique to cover the skin defect produced by excision of a mucous cyst of a digit

“…7 Treatment has ranged from total excision of the joint to multiple needling and expression of the contents. 8 It was not until the 1970s that communication of the cyst into the joint space was demonstrated, 9 establishing the need to trace the pedicle into the joint space combined with osteophytectomy with appropriate skin cover 10,11 in order to prevent recurrence. 12 Designing local flaps when the secondary defect is to be closed directly in an unforgiving area like a finger can tax even the skill of an experienced plastic surgeon.…”
