Corneal dermatoid tumor is a tumor-like congenital developmental abnormality of the eye, formed when the epidermis and its attachments are embedded in the corneal tissue during the closure of the embryonic cleft, while it is a typical mydriasis. In the past, the recurrence rate of corneal dermatoma was high after simple excision, and the trauma left permanent cloudy area with neovascular growth, which was not effective in treatment. In the past three years, corneal dermatome excision combined with lamellar corneal transplantation was carried out, and the postoperative treatment results were satisfactory. In the past three years, the ophthalmology department of the hospital operated on 10 children with corneal dermatomal tumors, 6 males and 4 females, aged 5 months to 8 years, with 3 tumors located in the superior temporal corneal limbus and 7 in the inferior temporal corneal limbus, and 1 case with an underlying mass and pseudopterygium. The tumors were 3-8 mm in diameter, and all children underwent tumor resection combined with lamellar or deep lamellar corneal transplantation under general anesthesia, and one patient underwent corneal limbal stem cell transplantation. Postoperative pressure dressing was applied to the operated eye, and ophthalmic drugs such as glucocorticoids, antibiotics, immunosuppressants, corneal repair agents and artificial tears were administered, and corneal sutures were removed 3-6 months after surgery. Six months to one year after surgery, the tumor resection area implants were well aligned, the wound healing was good, the corneas of 6 patients regained transparency, 3 patients had residual mild corneal opacification, and 1 patient had mild fibroplasia and neovascularization. No recurrent patients have been seen. Combined lamellar or deep lamellar corneal transplantation is a good choice for corneal dermatome surgery because of its reliable efficacy, high safety and low recurrence rate.
