Pinworm granuloma of cervix uteri--incidental observation following IUD use and cone biopsy

A pinworm granuloma of cervix uteri was found incidentally in a hysterectomy specimen following cone biopsy for severe epithelial atypia. This lesion was regarded as too recently formed to be related to prior IUD use. The granuloma was apparently asymptomatic, as were 24 of 34 such lesions cited as involving uterus, adnexa or pelvic peritoneum or some combination of these sites. The only previous instance to be found of apparently deep cervical invasion by pinworms was associated with grossly evident carcinoma; the intact cervix has not yet been reported as subject to pinworm invasion.
