When Duong, 23, visited Tam Anh General Hospital in Ho Chi Minh City, her visual acuity in both eyes was 10/10. However, her right eyelid presented a large, abnormally raised growth that caused no pain.

The patient had previously undergone surgery to remove an eyelid tumor at the same location at another hospital two years prior. Doctor Le Thi Thanh Hai, a specialist in ophthalmology at the High-Tech Eye Center, suspected a recurrence and ordered a head MRI (magnetic resonance imaging) for diagnosis and to determine an appropriate treatment plan.

MRI results revealed a large tumor measuring 2.5 x 3.2 x 5.6 cm, with damage to the soft tissue surrounding it. No abnormalities were noted in the brain parenchyma or eye sockets. Doctors diagnosed it as a right eyelid dermoid cyst.

Although the tumor did not affect the eye socket or optic nerve, the MRI images indicated infection and invasion into the periosteum. Doctor Hai stated that without timely treatment, this could lead to facial bone deformity.

Doctors scheduled the patient for eyelid tumor removal surgery. Due to the previous operation, the tumor's fibrous capsule was densely adhered, making complete separation challenging. If any abnormal cells remained, the tumor risked further recurrence. The large size of the tumor also necessitated a larger incision, increasing the risk of scarring.

The surgical team marked the tumor's location and defined the dissection area. They then made an incision along a natural skin crease to minimize scarring. During the procedure, doctors completely removed the tumor along with surrounding tissue to reduce recurrence risk. Finally, they closed the incision with cosmetic sutures. The biopsy of the specimen confirmed it was a benign, superinfected dermoid cyst.

At a follow-up appointment one week later, the patient's incision had recovered well, with no swelling or pain, and the stitches were removed. After three weeks, the incision had healed properly, and the scar was fading. Doctors advised the patient to avoid strenuous activity, refrain from rubbing her eyes, keep the surgical area clean, and attend follow-up appointments. She was also instructed to return to the hospital if she noticed any abnormal signs such as redness, pain, discharge, or blurred vision.

Dermoid cysts are benign growths formed when skin cells become trapped under the skin, commonly found on the head, face, and around the eye sockets. They can appear spontaneously or after trauma or surgery. If left untreated, a cyst can rupture, leading to inflammation and increasing the risk of recurrence after surgery.

If an abnormal growth or lesion appears on the eye, especially with accompanying signs like pain, discoloration, inflammation, ulceration, or rapid growth, patients should seek early examination and treatment at a hospital. Avoid self-treatment such as squeezing, puncturing, or applying home remedies to prevent infection.
