Collagenase followed by compression for the treatment of earlobe keloids
BACKGROUND: Many therapeutic options are available for treating keloids, but success rates vary widely, and the keloids often recur. The Food and Drug Administration has recently approved intralesional collagenase for the treatment of Dupuytren's contracture. This medication has not been explored for the treatment of earlobe keloids, a common problem. OBJECTIVE: To evaluate the safety and clinical efficacy of intralesional collagenase followed by compression for the treatment of earlobe keloids. MATERIALS AND METHODS: Six earlobe keloids in six patients were injected with a commercial collagenase preparation. Study participants were asked to use compression earrings daily thereafter. Patients were examined and photographed 1 day, 2 weeks, 4 weeks, 10 months, and 12 months after injection. Adverse events were assessed at each visit, and the keloids were measured and photographed. RESULTS: All patients had a decrease in the size of their earlobe keloid by an average of 50% (p = .02). Three of the six participants chose to have their earlobe keloids surgically excised for cosmetic reasons 6, 8, and 11 months after enrollment, so measurements for data analysis for these patients were taken after only 1, 1 and 10 months. All participants returned for follow-up at the last study visit 1 year after study commencement. The three patients who completed the study were pleased with the improvement of their earlobe keloid, although complete clearance was not achieved. Side effects included injection site swelling, tenderness, and one ulceration that spontaneously resolved within 2 weeks. CONCLUSION: Intralesional collagenase followed by compression appears to be a safe and modestly effective treatment for earlobe keloids. This approach warrants further investigation in larger studies with longer follow-up in motivated patients who decline surgical excision.
Colorectal cancer metastasis presenting as a testicular mass: case report and review of the literature [Case Report]
Metastatic lesions to the testicle are uncommon. The authors report a testicular mass as the initial manifestation of distant metastasis from colorectal cancer. This case describes a 51-year-old white man who presented with an enlarged right testicle 9 months after undergoing a right hemicolectomy for a stage IIIC colon adenocarcinoma. The diagnostic and management strategy is discussed. In addition, the literature is reviewed to characterize this uncommon entity further. Although rare, testicular metastasis must be considered in patients with previously resected colorectal carcinoma.
