Endometritis granulomatosa: hallazgo histológico en procesos de diferente etiología

Granulomatous endometritis is a chronic inflammation histologically characterized by the presence of granulomas in an endometrium with lymphoplasmacytic infiltrate. A finding of granulomatous endometritis in the biopsy or endometrial specimen should lead to suspicion of genital tuberculosis. This infection used to be rare in women. Tubal, endometrial and ovarian localizations are almost always secondary to a focus in another location. This entity is less frequent in postmenopausal women, probably because the atrophic endometrium provides a poor environment for growth of the tuberculosis bacillus. The definitive diagnosis of genital tuberculosis is culture of the Koch bacillus. A presumptive diagnosis can be made on the basis of granulomas in biopsy and a positive Mantoux test. Treatment is medical and the prognosis is good. We present five cases of genital tuberculosis in postmenopausal women, diagnosed between June 2001 and April 2003.
