An unusual case of adult filarial oophoritis.

Ovaries are the least involved site of infection in the female genital tract. Parasitic infestations of the ovary are even rarer. We report an unusual case of adult filariasis of the ovary discovered incidentally on histopathologic examination. Panhysterectomy was performed on a 47-year-old north Indian woman with multiple uterine fibroids, where menorrhagia was unresponsive to hormonal therapy. An adult nongravid female filarial worm was identified in the dilated ovarian lymphatic system. The host local immune response was minimal. Subsequent work-up failed to show any physical stigmata or diagnostic evidence of the disease. The structural details of the adult worm are characteristic to permit its recognition on histologic examination. The involvement of an adult worm in the female genital tract is distinctly uncommon in comparison with the male genital involvement. Till date, only a handful of cases of ovarian adult filariasis are reported.
