Developing Eye in an Ovarian Teratoma

Mature ovarian cystic teratoma with a highly differentiated homunculus: A case report

“…Solid nodules are often observed within the tumor capsule, and these may contain cartilage or calcified tissues, such as teeth (Blackwell et al, 1946). Visceral tissue (Miyake and Ireland, 1986), pituitary gland (Fenoglio et al, 1982), prostate gland (Melniker and Slavutin, 1980), eye (Mercur et al, 1976; Inoue et al, 1985), pulmonary tissue (Blackwell et al, 1946), and mammary gland (Richard and Dobbs, 1976) have all been described, but they are rare.…”

Ocular structures in a mature ovarian teratoma

“…Multiple prior reports have described retinal and choroidal structures in mature teratomas. 1 , 2 However, few have previously described corneal, conjunctival, and lenticular tissue, which are most commonly seen as part of a fully formed eye within a teratoma. 1 , 2 , 3 This image reveals the first-reported, isolated corneal and conjunctival tissue with developing lenticular structures in a mature ovarian teratoma.…”

Retinal tissue in mature cystic teratoma of ovary presenting with full-term pregnancy

“…However, no concrete evidence is available on whether the presence of this element is associated with any prognostic or therapeutic significance and this remains a potential area for the future research. Mercur et al ,9 who observed retinal tissue in a developing eye in immature teratoma of the ovary advocated extensive tumour sampling whenever such uncommon elements are found in MCT, to rule out the presence of any immature component as it adversely affects the prognosis and changes the approach to treatment 9…”
