“…These glands account for approximately 10% of the total lacrimal secretory mass (Conrady et al 2016). Furthermore, reports in the literature describe ectopic lacrimal glandular tissue (Dallachy 1961;Solaroglu et al 2005). Such ectopic lacrimal gland tissue, though very rare, may also harbour a tumour (Patyal et al 2010;Alsuhaibani 2012;Obi et al 2013).…”

“…In humans, lacrimal gland tissue has been found in the iris and ciliary body in 14 cases (Table 1). The lesion in most cases was found Shields et al Year published 1887195219521960196119671985199019971999 (Rowley, 1997), the lesion was found at age five. In all 14 cases, the choristoma occurred unilaterally.…”

“…Therefore, how the lacrimal tissue can reach the iris and ciliary body is mysterious. Some theories have postulated (Bruce, 1952;Christensen & Anderson, 1952;Dallachy, 1961;Hunter, 1960;Morgan & Mushin, 1972), and Conway et al summarized these as follows: (1) early aberrant implantation of embryonic cells destined to become lacrimal glands, (2) implantation with surface epithelium during the formation of the lens, (3) pinching off of lacrimal gland buds by closure of the fetal fissure at the time when the two are in proximity, in particular if there is a delay in the closing of the fissure, (4) intraocular extension of lacrimal tissue along pre-existing scleral defects which may later close, and (5) aberrant differentiation of embryonic intraocular tissue rather than an aberrant implantation.…”

Choristomas have been reported in the orbit, cornea, conjunctiva, uvea, retina, and optic nerve. Many reports have described the choristoma mainly in the epibulbar area, but little is known of the choristoma that occurs intraocularly. We reviewed the literature and summarized the reports that described the choristoma inside the eyes. Iris, ciliary body, choroid, and optic nerve head are the commonly affected tissues. In the anterior uveal tissue, an ectopic lacrimal gland is common and appears as a pinkish, nodular, fleshy mass. Its clinical course largely depends on the enlargement of the accompanying cyst. Osseous choristoma is mainly found in the choroid in young female patients. Although it is regarded as a benign tumor, it grows progressively and can decrease visual function. Treatment consists of close observation and possibly surgical intervention. Fortunately, most of the intraocular choristomas do not need aggressive treatment.

“…1999;117:110-111 Choristoma consisting of lacrimal gland tissue has been most frequently described in the orbit or on the outer eye, whereas intraocular growth is an extremely rare phenomenon. We found 12 cases [1][2][3][4][5][6][7][8][9][10][11][12] in the literature from the first description by Puech in 1887 1 to the most recent by Rowley in 1997. 12 Most of these eyes had been enucleated either primarily, because of the unknown identity of the tumor and associated problems, or secondarily because of phthisis following resection.…”
