Abstract A 28 - year - old man presented with erythema, swelling, and pain in the right buttock. He was aware of the fact that the right buttock was larger than the time of birth. Laboratory data showed inflammatory reaction, and pelvic CT scanning revealed multifocused cyst in the subcutaneous tissue. In histpathological study, there were dilated limphatic channels in the dermis. From these findings, the case was diagnosed with Lymphangioma circumscriptum with infection. The patient’s symptoms improved by the treatment with antibiotics and drainage.
