Xanthogranulomatous inflammation of the perimetrium with infiltration into the uterine myometrium in a postmenopausal woman: a case report

BACKGROUND: Xanthogranulomatous inflammation is an uncommon form of chronic inflammation that is destructive to the normal tissue of affected organs. Although xanthogranulomatous endometritis and xanthogranulomatous salpingitis of the female genital tract has been described previously, to the best of our knowledge, this is the first report of xanthogranulomatous inflammation with infiltration into the uterine myometrium from the perimetrium without endometritis. CASE PRESENTATION: A 68-year-old Japanese woman with intermittent lower abdominal pain and low-grade fever who was initially treated with antibiotics underwent hysterectomy due to abscess formation in the posterior wall of the myometrium and perimetrium (the outer serosal layer of the uterus). Histopathological findings revealed that the abscess was caused by xanthogranulomatous inflammation with the granulation tissue and chronic inflammatory cells that consisted of focal and sheets of foam cells. The inflammation destroyed the perimetrial elastic lamina, and the myometrium was deeply infiltrated by the xanthoma cells. Neither endometritis nor salpingitis was coexistent with the xanthogranulomatous inflammation. CONCLUSION: The patient was diagnosed as xanthogranulomatous inflammation, most likely arising from the perimetrium. Our findings suggest that the perimetrium, as well as the endometrium and adnexae, is one of the origins of xanthogranulomatous inflammation in female genital tract

Recurrence of Ovarian Cancer with Placental Metastasis: A Case Report

A 39-year-old primiparous Japanese female was admitted to the obstetrical emergency department of our hospital because of respiratory distress resulting from a large amount of pleural effusion, soon after a caesarean delivery (CD) at another hospital. While she was undergoing the CD, a giant ovarian tumour was identified. However, the tumour could not be removed at that facility and she was transferred to our hospital. Three days after the CD, a left salpingo-oophorectomy was performed with the purpose of controlling pleural and peritoneal effusions. Based on her past treatment history and the information gathered from this surgery, recurrence of ovarian cancer was considered the final diagnosis. Earlier, at the age of 37 years, she had been diagnosed with stage IC ovarian adenocarcinoma arising from a mature cystic teratoma detected after a right salpingo-oophorectomy. These kinds of situations of accidental detection of recurrent advanced ovarian cancer in a newly pregnant patient in the emergency department are rare. Amongst them, we have identified an extremely rare case showing placental metastasis. The important lesson learnt from this case report is that detailed medical interviews and physical examinations are crucial when a pregnant woman visits a hospital without a letter of referral, especially in the third trimester of pregnancy
