Transvaginal sonogram reveals an enlarged, soft, and tender uterus, and uterine biopsy shows normal-appearing endometrial glands within the myometrium. Which of the following is the most likely diagnosis in this patient:? A: Adenomyosis, B: Endometriosis, C: Endometritis, D: Leiomyoma, E: Endometrial carcinoma,  <response>: This is a clinical case scenario involving a 40-year-old female with symptoms of dysmenorrhea, menorrhagia, and pelvic pain. The key findings are an enlarged, soft, and tender uterus on transvaginal ultrasound, along with endometrial glands within the myometrium on biopsy. Based on the patients age, symptoms, and imagingbiopsy findings, this is most consistent with adenomyosis. Adenomyosis involves the abnormal presence of endometrial glands and stroma within the myometrium. It often presents with dysmenorrhea, menorrhagia, and enlarged uterus. Endometriosis and endometritis would not explain the uterine enlargement or biopsy findings. Leiomyomas may cause enlarged uterus but not the other histologic findings. Endometrial carcinoma would be unlikely given her age and benign appearing glands on biopsy.A: Adenomyosis
