To our knowledge, this article reports the first case of two late SCTG complications, epithelial cell discharge, and subsequent epidermal inclusion cyst (EIC) formation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case Presentation<\/jats:title><jats:p>A 35\u2010year\u2010old male presented with a 3\u2010mm deep Miller Class II recession defect on the mandibular right canine and mesial root of mandibular right first molar. A mild discomfort was reported at 8 weeks after envelope flap+SCTG in #27. At 4 months after the procedure, the patient presented with persistent discomfort and minimally compressible recipient site diffuse swelling with discharge, which was cytologically diagnosed as normal epithelial cells. One year postoperatively, enlargement of the lesion was seen, and excisional biopsy was performed simultaneously with SCTG in #30. The lesion was diagnosed as EIC. At 8 months follow\u2010up, the site healed uneventfully, the patient remained asymptomatic, and the site exhibited scar formation and no recurrence of the lesion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This report highlights epithelial cell discharge and EIC formation as a rare yet possible SCTG complication and
