Myomatous erythrocytosis syndrome: A case report

Figure 1 The blood that was removed from the patient. The first pack (left) was dark brown, while the second pack (right) was dark red after fluid infusion.

Figure 2 Gross and microscopic analysis of the uterus. A: The uterus weighed 6500 g, with the largest diameter of 35 cm; B: The sagittal plane of the uterus showed that the large myoma originated from the posterior wall of the uterus, with the cut surface appearing yellow white with scattered red hemorrhagic areas; C: Under the microscope (200 ×), via immunohistochemical staining, the cytoplasm of the leiomyoma cells of this patient showed strong positivity for erythropoietin; D: Compared with the myoma of this patient, the myoma of a patient without erythrocytosis showed weaker erythropoietin staining in immunohistochemical analysis (200 ×).

Figure 3 Changes in hematological parameters during the perioperative period. All the hematological parameters decreased following the operation, with hemoglobin declining the most sharply immediately after the surgery.
