OBJECTIVE Xanthogranulomatous inflammation (XGI) is a rare form of chronic inflammation that affects the female genital tract (FGT). The absence of a standard lexicon in the literature has contributed to the relative obscurity of this condition. We attempt to study this lesion with its various clinicopathological associations. METHODS We conducted an 11-year retrospective study of cases diagnosed with XGI of the FGT, analyzing relevant clinical and pathological parameters. RESULTS Our study identified 40 cases reported as XGI. The mean age was 43.8 (+/- 11.8 SD) years. The most common clinical presentation was abdominal pain (27.5 %). Abdominal mass was seen in 37.5 % of which 22.5 % was primarily attributed to XGI and was not associated with malignancies. The most common site involved was adnexa(87.5 %), with rare involvement of myometrium(7.5 %) and endometrium(5 %). Adnexal involvement was either as tubo-ovarian masses or isolated ovary/fallopian tube involvement. XGI was also seen associated with other primary lesions of FGT like high-grade serous carcinoma(7.5 %) and mature cystic teratoma (7.5 %), while non-neoplastic associations included tubal gestation, foreign body, and Aspergillus infection in the ovary. Histologically, the infiltrate comprised of chronic inflammatory cells in all cases with additional acute inflammatory cells(60 %). Multinucleated giant cells were seen in 40 % of cases. Urine culture showed bacterial colonies in 23 % of cases. CONCLUSIONS XGI of FGT is an extremely rare lesion and can present as isolated lesions or in association with other primary lesions of FGT. Adnexal involvement was more common than uterine XGI. It is essential to recognize this lesion because it can mimic malignancy and has a destructive nature.

D010053 Ovary The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE. Ovaries
D004717 Endometrium The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo. Endometria

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D014599 Uterus The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
