A case of herpetiform appearance of digital mucous cysts

The outcome of minimally invasive surgery for digital mucous cyst: a 2-year follow-up of percutaneous capsulotomy

Background: Digital mucous cyst(DMC) is the most common tumor or cyst of the hand. Although many operative methods have been proposed to treat DMCs and lower the recurrence rate, many patients hesitate to have surgery. A minimally invasive treatment using percutaneous capsulotomy for the DMCs could be an alternative choice. However, the clinical results of using this method are still uncertain.Objectives: Here, we introduce the percutaneous capsulotomy method and assess the clinical outcomes and the associated complications of this method. Methods: A total of 42 digits were finally included. All patients accepted percutaneous capsulotomy under a digital ring block. Functional and radiographic assessments were made pre- and postoperatively, with a mean of 28.8 months (range, 24-33 months) of follow-up. Results: The mean duration of the appearance of DMCs before treatment was 11.6 months. Of the 19 digits with nail deformity, 14 showed an improved nail appearance. There were no skin complications. The average visual analogue scale (VAS) satisfaction score was 9.4, only two cases had experienced recurrence at the final follow up. Conclusions: This study reported that percutaneous capsulotomy could be an effective method for DMCs treatment. The recurrence rate was low and patient satisfaction was good. Nail deformities could be improved with treatment.

Digital Mucous Cyst: A Clinical-Surgical Study

Background

It has been suggested digital mucous cysts (DMCs) are associated with osteoarthritis and osteophytes in the elderly, and usually have a communicating pedicle with the joint. Surgical excision is a standard therapy with a high cure rate.

Objective

The purpose of this prospective study is to evaluate the features of DMCs via clinical, radiological and pathological examination and the efficacy of surgical excision of DMCs.

Methods

Between 2010 and 2014, 24 Korean patients were treated with the resection of the cyst and the pedicle. Preoperative X-ray and ultrasonography were performed to detect the presence of the osteophyte and the connection to the joint space. Postoperative patients' satisfaction score was assessed by the visual analogue scale (0~10).

Results

The osteophytes were found in 15.8%. In ultrasonographic findings, there were prominent flow signals between the cyst and the joint space in 13.6%. There were no serious postoperative complications, and recurrences were observed in 16.7%. Mean postoperative satisfaction score was 8.3.

Conclusion

It seems that preoperative X-ray for osteophytes and ultrasonographic study for connection are not always helpful for the treatment of DMCs, and that the surgical excision with a pedicle ligation and electrocoagulation is an effective treatment modality.

Dermatoscopic pattern of digital mucous cyst: report of three cases

Digital mucous cysts are benign ganglion cysts of the digits typically located on the dorsal aspect of the interphalangeal joint and distal phalanx of the digits. Usually the clinical diagnosis is straightforward, though sometimes it may mimic other lesions and diagnosis becomes a challenge. We present a series of three digital mucous cysts with a repeatable dermoscopic pattern consisted of linear branched and serpentine vessels when no compression is applied and translucent aspect with white bright areas and loss of vascular pattern when compression is applied.
