Primary Orbital Teratoma with Tooth in an Adult: A Rare Association with Cataract and Corectopia

Abstract

This report documents a unique case of orbital teratoma presenting in an adult with well formed canine tooth inside. Microcornea, corectopia and cataract were other distinctive coexisting features of our case.

Primary lacrimal gland teratoma in an adult: A clinicopathologic and radiological correlation

“…[6] Although orbital teratoma can be malignant, most frequently the tumor is benign in nature. [123456] Several classification systems have been proposed for orbital teratomas. [1] While Duke-Elder classified orbital teratomas based on the degree of differentiation of the three germ layers, Kivela et al .…”

“…Orbital teratomas usually present in a neonate as unilateral proptosis. [123] Primary orbital teratoma in an adult has been reported earlier, but is extremely uncommon. [345] Although Levin et al .…”

“…[123] Primary orbital teratoma in an adult has been reported earlier, but is extremely uncommon. [345] Although Levin et al . described a primary orbital teratoma in a 15-year-old-female, the teratoma had been present for at least 13 years with gradual progressive growth.…”

“…[1] The most characteristic presentation of this tumor in the orbit is extreme proptosis present at birth. [123456] Herein, we report an unusual presentation of a primary lacrimal gland teratoma in a 20-year-old patient.…”

“…[2] In contrast, orbital teratoma is rare, but a well-known entity. [12345] Orbital teratoma almost always presents as a unilateral mass, and the stimulus for differentiation of the pleuripotential germ cells toward adult structures in the orbit is not clear. [1] The most characteristic presentation of this tumor in the orbit is extreme proptosis present at birth.…”
