Pseudo-sulfur granules associated with intrauterine contraceptive devices

A structure resembling a sulfur granule found in histologic sections of endometrium from patients with intrauterine contraceptive devices is described. It is distinguished from a true sulfur granule on morphologic grounds and is further characterized as a foreign substance, most probably fragments of the synthetic contraceptive device. It is not associated with clinical disease. Microbiologic cultures of removed intrauterine contraceptive devices show no consistent or predominant growth pattern.
