Lacrimal sac cysticercosis: a rare site for manifestation.

Cysticercosis, a parasitic tissue infestation caused by larval cysts (cysticercus cellulosae) of the pork tapeworm, Taenia solium, most commonly affects the central nervous system, subcutaneous tissue, skeletal muscle, heart muscle, and the eye. Ocular adnexal infestation in cysticercosis can involve various sites within the eye like vitreous humor, subretinal tissue, extraocular muscle, and lacrimal gland. In this case report, a lump slightly below and medial to inner corner of eye, surgically removed from a 21-year-old male patient, was diagnosed as case of lacrimal sac cysticercosis on histopathological examination. To our knowledge, this is the one of rare sites for manifestation of cysticercus cellulosae.
