Abstract

Most cases of nodulocystic acne do not require aspiration before intralesional corticosteroid injection. However, in extreme circumstances, when the cyst is already tense, the appropriate amount of the drug cannot be injected without aspiration of the cyst. Unfortunately, aspiration and injection of drug by a single syringe is not possible because this causes contamination and dilution of the drug to be injected; moreover, the syringe needs to be changed during the procedure, causing slight maneuvering of the needle, which is cumbersome to the physician and painful for the patient.
