Abstract

A 17-year-old male patient presented with cellulitis and mass in the eye noticed approximately 3 months back. The mass was about 1 cm in size and situated at the limbus. All preoperative routine investigations were normal. Surgical exploration revealed a sub-conjunctival cystic mass near the lateral rectus muscle about 1 cm in diameter; the mass was excised. Gross pathological examination revealed a thin-walled cystic mass. There was a hard nodule in the center. Microscopy revealed a wall of cysticercosis. Scolex was also seen. Surrounding tissue revealed sparse acute and chronic inflammatory cells. The case was confirmed by CDC, Atlanta, and was also included in their departmental presentation as an interesting case. A 60-year-old lady presented with complaints of itching over the forehead and right eye for 5 days. She was prescribed steroid eyedrops and antihistaminics. The itching aggravated with eyedrops along with watering and foreign body sensation. On revisit, the ophthalmologist noticed a worm in the right upper subconjunctival space. The worm was carefully removed in toto and sent to the laboratory for identification. The worm was thin, cylindrical, 8-10 cm long and white in color. After microscopic and gross examination of the worm, it was identified as Dirofilaria spp. CDC (Atlanta) confirmed the diagnosis of Dirofilaria. The patient was treated with antihistaminics and was relieved of symptoms without recurrence. A 45-year-old male patient had a painless mass in the eye for the last 3 months. He had no systemic illness. He gave a history of swimming pool use during that time. The mass was excised and submitted for histopathology. Numerous globular cysts representing thick-walled sporangia containing numerous spores diagnostic of Rhinosporidiosis were seen.
