Heavy menstrual bleeding due to primary myelofibrosis in a woman: a case report.

Heavy menstrual bleeding (HMB) due to primary myelofibrosis (PMF) is secondary to progressive pancytopenia, which is a rare and difficult to treat condition. We report this case with the aim of sharing our experiences and exploring a safe and effective way to treat patients with HMB due to PMF. A 40-year-old woman who had been taking combined oral contraceptives (COCs) for eight years was admitted to our hospital with HMB. A bone marrow biopsy report and genetic testing confirmed the diagnosis of PMF. Norethisterone tablets had an unsatisfactory hemostatic effect. The patient underwent a hysteroscopy and the insertion of a levonorgestrel intrauterine system (LNG-IUS). At the 5-month follow-up, the patient had a lower menstruation bleeding volume. COCs are unsuitable for managing the menstruation of patients with PMF in the long run. Endometrial ablation is the long-term method. However, the patient's fertility requirements should be taken into account. The insertion of an LNG-IUS after hysteroscopic curettage to exclude endometrial malignant lesions is recommended.
