Patient case (clinical description): A 43-year-old woman, gravida 3 para 3, comes to the clinic complaining of recently painful menstrual cycles.  The patient's last menstrual period was 2 weeks ago. Urine β-hCG is negative. Menarche was at age 12, and menstrual periods occur every 28 days and lasts for 5 days.  She is sexually active with her husband and does not have pain with intercourse. BMI is 23 kg/m2 and Vital signs are normal.  On physical examination, the uterus is uniformly enlarged and tender. She is candidate for hysterectomy with the diagnosis of adenomyosis.

Patient's own account: I'm 43, and I paid a visit to my doctor because my last few periods were insanely painful. My last periods were 2 weeks ago. I already had three pregnancies that gave me the three lovely children. I did a urine test to check for potential pregnancy, and it came back negative. I started to have my periods at the age of 12, and I have been pretty regular with periods every 28 days for 5 days. I'm sexually active with my husband and I do not have any pain when we have sex. My BMI is 23 and my vitals were normal. The doctor performed a physical exam and found that my uterus was tender and enlarged. She proposed me a hysterectomy and diagnosed me with adenomyosis.
