Histopathological slide of the first surgery of this patient. The oviduct smooth muscle cell area had been invaded by pleomorphic cells, in particular, spindle cells. N indicates necrosis of the oviduct smooth muscle area; T: tumor area, which contained multiple spindle cells.

Histopathological analysis (Figure 1) revealed multiple smooth muscle cells, lipoblasts, and pleomorphic cells; the smooth muscle cell area had been invaded by pleomorphic cells, especially spindle cells.
Auxiliary examinations of the patient, the abnormal sites have been labeled by red arrows. There was a mixed echogenic mass in her left lower quadrant of the abdomen on sonography (2A, on the left). There was a large lesion in the left lower abdominal mesenteric area as observed on abdominal CT images (2B, middle). Her thorax CT scans showed a funicular image in the inferior lobe of the left lung (2C, right).

Sonography (transabdominal ultrasound) (Figure 2A) showed an 11.3 x 7.9 x 11.3 cm-sized mixed echogenic mass in the left lower quadrants of the abdomen, the boundary of which was relatively clear, and there was a small number of blood flow signals. A preoperative computed tomography (CT) (Figure 2B) scans upon admission showed multiple small lymph nodes in the retroperitoneum, and multiple lesions in the left side of pelvic cavity and the left lower abdominal mesenteric area. Her thorax CT scans (Figure 2C) showed a funicular image in the inferior lobe of the left lung.
Histopathological slide of the pelvic wall mass of the second surgery. It revealed the lipoblasts and pleomorphic cells. The black arrows indicate lipoblasts, which were characterized by heterotypic, hyperchromatic nuclei with uni/multivacuolated cytoplasm. The blue arrow indicates one of the pleomorphic cells, polymorphonuclear cell.

Reports on histopathology (Figure 3) of these masses revealed reports similar to previous reports.
