Background: Steatocystoma is a benign cystic lesion. Steatocystoma multiplex presents as multiple lesions that occur frequently on the axilla, chest and upper limbs. Cyst removal as treatment is fundamental; methods include simple excision, puncture aspiration, punch biopsy excision and CO2 laser. However, this is difficult due to the widespread lesions of steatocystoma multiplex. We have devised a new treatment approach for steatocystoma multiplex, which involves minimally invasive incisions and the use of foreign body forceps. Method: We first made an incision of approximately 1 mm with a scalpel. While extruding the contents, foreign body forceps were advanced to grasp the inner wall of the cyst capsule. The cyst wall was peeled off from its surroundings and was removed as a lump. This was repeated for each of the cysts presented. Result: The excision time per cyst was approximately 1 minute. Since no sutures were required, 20-30 excisions could be made in a single setting within 30 minutes. The wound was hardly conspicuous. Consideration: Steatocystoma multiplex often causes stress to patients in terms of aesthetics, resulting in the desire to be treated. We think that this method of using foreign body forceps on minimal incisions is an optimal surgical technique because it is simple, with short operation time and reduced patient burden.
