These cysts originate from the follicular infundibulum, which when obstructed by keratin, results in cyst formation. Conventionally, E.C.s have been managed surgically with a high success rate and minimal complications. In this report, we present the successful resolution of an E.C. using a minimally invasive technique involving the intralesional injection of recombinant hydrolytic enzymes like hyaluronidase, collagenase, and lipase.Case Presentation: A 44-year-old woman with no significant medical history presented to the clinic with a mass on her right cheek that had been evolving for over 10 years. Skin and soft tissue ultrasound confirmed the presence of an E.C. of 9.3× 6.6 × 9.3 mm. Owing to the size and location of the cyst, a decision was made to infiltrate the lesion with recombinant enzymes. Remarkably, significant clinical improvement was observed on Day 21, and complete dissolution of the E.C. occurred 40 days after the initial intervention. Importantly, no recurrences were observed during the 4-year follow-up period.Conclusion: Intralesional administration of hydrolytic enzymes represents an innovative technique in the management of E.C.s. However, further controlled studies are required to determine the efficacy and safety of this procedure.Keywords: epidermoid cyst, hyaluronidase, lipase, collagenase, sebaceous cyst
