In October 1982, a 41-year-old man was seen because of multiple soft tumors on the upper half of his body. These tumors were up to 3 cm in diameter. His parents were not consanguineous. His family, including his 18-and 19-year-old children, had no history of similar lesions. At 16 years of age, our patient first noticed subcutaneous nodules on his neck. Since then, the number and size of the nodules increased.When he was 20 years of age, there were many nodules on his head, neck, trunk, and upper extremities. The nodules continually discharged oily material and became inflamed and tender. Following a diagnosis of steatocystoma multiplex, 25 cysts on his head were surgically excised with 750 mL ofblood loss. The oily material was sterile. About 75 smaller cysts on the trunk were excised and drained, and the walls of cyst were treated with 60% trichloroacetic acid. Findings from his physical examination showed mild liver dysfunction, mild hyperlipidemia, and a duodenal ulcer, but other clinical and laboratory data showed normal results.In 1991, he requested removal of the remaining cysts ( Fig 1). About 10 cysts (diameter, 1 to 3 cm) were excised from the arm, neck, and forehead during the next 2 months. However, we realized that the procedure was very time consuming and stressful and that total surgical removal of all of the cysts in such a florid case of steatocystoma multiplex was not feasi¬ ble. We then attempted aspiration. From June through Sep¬ tember 1991, cysts larger than 1 cm in diameter were aspi¬ rated and scraped with a syringe connected to an 18-gauge needle (caliber, 1.20 mm; bevel, 18 degrees; Terum, Tokyo, Japan) (Fig 2). The result was satisfactory, and the patient's psychological condition showed much improvement. In January 1992, the smaller remaining cysts were incised and drained. By March 1992, the larger cysts that were as¬ pirated and scraped 10 months before did not enlarge (Fig 3), but the smaller ones that were incised and drained had already started to enlarge (Fig 3). Biopsy specimens were obtained from cysts that were aspirated and scraped and those that were incised and drained.
THERAPEUTIC CHALLENGEAlthough the observation period of 10 months is short and small cysts cannot be treated well with only aspiration, our method for the treatment of larger cysts of steatocystoma multiplex could improve the cosmetic appearance of the pa¬ tient's facial lesions with little scarring.
THERAPEUTIC SOLUTIONWhen the cysts were aspirated, the tip of an 18-gauge nee¬ dle was inserted into the cyst. During aspiration, the tip was moved and rotated to scrape off the sebaceous glands in the cyst wall. In order to minimize inflammatory responses due to the leak of oily material and injury to blood vessels, we avoided multiple punctures of the cyst walls and tried to scrape them gently, which we could feel. The aspirated yel¬ low oily material contained many clusters of vellus hairs and keratin. One mature hair about 5 cm long was aspirated from a cyst. It was difficult to aspirate oily material with...
