Abstract

Giant cell arteritis (GCA) is an immunologically mediated vasculitis of large and medium-sized vessels, typically affecting the cranial arteries and usually occurring in the elderly. GCA of the female genital tract is extremely rare with only 31 cases reported in the English literature. An 83-year-old white female with postmenopausal vaginal bleeding revealed an endometrial polyp on pelvic ultrasonography following which polypectomy and subsequently hysterectomy with bilateral salpingo-oophorectomy was done. Microscopy revealed a well-differentiated endometrioid adenocarcinoma. Interestingly, classic GCA involving numerous small to medium-sized arteries of the cervix, myometrium, bilateral fallopian tubes, and ovaries was also identified. Hematologic evaluation revealed marginal zone lymphoma with an exceptionally rare 20q deletion. Bilateral temporal artery biopsy was done subsequently, which exhibited GCA on microscopy. Corticosteroid was started that improved her polymyalgia rheumatica symptoms. The patient is on follow-up for 3 years and is doing well. To our knowledge, this is the first case of GCA of the female genital tract associated with a lymphoma and the second case of marginal zone lymphoma with the novel 20q deletion.
