ABSTRACT
BACKGROUND:
An epidermal cyst is a common keratin-filled epithelial-lined cyst. The treatment of choice for epidermal cysts is surgical excision. If the cyst becomes ruptured, incision and drainage with oral antibiotic therapy or intralesional steroid injection are required.OBJECTIVE:
To analyze the dermoscopic features that can differentiate between ruptured and unruptured epidermal cysts.METHODS:
The clinical and dermoscopic features of the pathologically confirmed epidermal cysts of two subgroups of 38 patients, 20 with unruptured cysts and 18 with ruptured cysts, were reviewed.RESULTS:
With regard to the dermoscopic features, an ivory- white background color and punctum were commonly found in both groups (p>0.05). The unruptured-cyst group showed higher frequencies of pore sign (p0.05), no vascular structure, and arborizing telangiectasia (p0.05) and peripheral linear branched vessels (with an erythematous rim) (p<0.05).CONCLUSION:
Dermoscopy is helpful in differentiating between ruptured and unruptured epidermal cysts.
