RESUMEN
We report a case of extramedullary hematopoiesis (EMH) in uterine leiomyoma and associated numerous intravascular thrombi. A 29-year-old nulliparous female presented with heavy vaginal bleeding and a hematocrit of 22%. No bone marrow biopsy has been performed. She had a history of uterine leiomyomata and menorrhagia for a year. A transvaginal ultrasound confirmed the presence of a uterine leiomyoma. The patient was treated conservatively with oral contraceptive pills due to desire for fertility. However, she continued to have heavy vaginal bleeding and developed bilateral upper extremity deep vein thrombosis and multiple superficial vein thromboses after two months. An exploratory laparotomy with uterine myomectomy was performed. Gross examination of the specimen revealed a single nodular mass measuring 10.0 × 9.5 × 7.5 cm with a white-tan swirling cut surface. Microscopic examination revealed benign smooth muscle consistent with leiomyoma and numerous intravascular thrombi both with areas of EMH. Immunohistochemical stains confirmed the presence of all three benign lineages of hematopoietic cells. Occurrence of EMH in uterine leiomyoma and intravascular thrombi is very rare. It may be related to systemic hematopoietic stimulation due to severe chronic anemia and local presence of hematopoietic growth factors and/or cytokines.
RESUMEN
BACKGROUND: The objective of this study was to evaluate the impact of a weekly tumor board conference on the management of patients with gynecologic malignancies. METHODS: The medical records of consecutive patients referred to a multidisciplinary gynecologic oncology tumor board were reviewed. Patient demographics were abstracted from medical records and tumor board minutes. An evaluation was made whether the pathological or radiological findings were changed by the tumor board consultants. If a discrepancy existed, it was determined whether the change impacted clinical management. RESULTS: From January 2004 to December 2006, 741 patients presented at the tumor board were evaluable. Seventy-one percent of the patients were presented for pathology review and 29% for radiology review. The most common diagnoses were ovarian cancer (29%), endometrial cancer (26%), and cervical cancer (12%). Of the 526 pathology reviews, 27% had a change in diagnosis; this discrepancy altered clinical management 74% of the time (20% of all reviews). Of the 215 radiology presentations, 89% were reviewed to confirm recurrent or persistent disease; malignant disease was confirmed 74% of the time. Review of imaging studies resulted in a new diagnosis or upstaging 10% of the time. CONCLUSIONS: A multidisciplinary tumor board allows a wide range of gynecologic diagnoses and clinical scenarios to be discussed. Careful review of pathology results in a change in the clinical management of 20% of patients presented at the tumor board. The majority of radiology reviews are presented to confirm persistent or recurrent cancer before recommending further therapy.
