Ectopic Teeth in Eyelid

A case of an ectopic tooth in the maxillary sinus.

“…Regarding the latter, SUBRAMANIAM [ 15] described that the cause of an ectopic eyelid tooth in his report originated from dermoid tissue due to the presence of skin and skin appendages, such as hair follicles and sebaceous glands, in the lesion. Because it is difficult to explain the presence of teeth in this case, the former explanation is suitable for the genesis of the present case since our case had no dermoid tissue.…”

Commentary: Supernumerary teeth

“…4 ‡ is an example where a supernumerary incisor (probably a mesiodens) is hidden in the subject's incisive foramen. The literature describes ectopic teeth located in various midface regions, such as the nasolacrimal duct (Alexandrakis et al, 2000), the bony orbit (Savundranayagam, 1972), and the eyelid (Subramaniam et al, 1966). Many of us were taught in an embryology class or elsewhere about dermoid cysts (e.g., Shafer et al, 1983), which contain well-differentiated skin and other identifiable tissues (e.g., hair, sweat glands, bone, cartilage, etc.…”

Congenital tooth-bearing tumor of the eyelid leading to lacrimal system obstruction

“…Three cases of palpebral tumors 11 , 12 , 13 and eight cases of orbital tumors 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 containing teeth have been previously described, with only five in the English literature. 15 , 17 , 19 , 20 , 21 Although these lesions were initially suggested to be teratomas, the pathologic classification of these tumors is not defined with certainty.…”
