Orbital dermoid cysts are the most common pediatric periorbital tumors. They may lead to compression and acute or chronic inflammatory response.
Here reported a 9-month-old patient showed nasal-superior and temporal-superior progressively growing masses. Computerized tomography suggested the presence of 2 dermoid cysts (Fig B, C, asterisk; Fig A, C, arrow).

ophthalmologist confirmed diagnosis for both lesions after excision and pathology examination. No other findings were reported. Despite the high prevalence of dermoid cyst, the presence of 2 periorbital dermoid cysts is extremely rare and thus has not been previously reported. Ectodermal cells were entrapped in the forming fetal mesodermic bones of the orbit in 2 different and independent locations.
