The Eye in Teratomas

Ectopic ocular tissue in testicular teratoma: A case report and review of the literature

“…Developing ectopic ocular tissue in extra-orbital sites is uncommon [4] . Nonetheless, only few reports have described teratomas containing ocular structures, which are summarized in Table 1 .…”

“…Occasionally, the eyelids, cornea, sclera, and vitreous can be seen. However, the lens is rarely observed [4] , [6] . Most of the ectopic ocular tissues arise within ovarian or sacrococcygeal teratomas.…”

“…Most bodily tissues are typically described in teratoma, including skin, bone, cartilage, connective tissue elements, epithelium of the respiratory and gastrointestinal tracts, smooth and striated muscle, and glial and nerve tissues. However, gonadal tissues, liver and ocular structures are very rarely seen [4] . Teratomas may appear anywhere in the body but are commonly seen in the gonads [4] .…”

“…However, gonadal tissues, liver and ocular structures are very rarely seen [4] . Teratomas may appear anywhere in the body but are commonly seen in the gonads [4] . Among prepubertal testicular tumors, teratoma is the second most common to arise following yolk sac tumor and occurs with ranging frequency between 13% and 60% [3] .…”

Congenital Orbital Teratoma

“…Most body tissues have been described in the tumor, but gonadal and liver tissue are rarely seen [2], Duke-Elder [4] clas sifies teratomas by differentiation and the number of germ layers repre sented. Teratomas can be an amorphous mass of tissue or present as a complete fetal structure [7], The morbidity and mortality described in the past was secondary to infection.…”
