Uterus grossly involved by neoplasia with a sagittal caesarean cut on its posterior face; ovaries were macroscopically free of disease, but we removed them in order to be radical.

LSCS (lower segment caesarean section) was not possible, so we performed a posterior vertical section (see Fig. 1) in order to achieve an "en bloc" extraction of the fetus, placenta, and amniotic sac.
CT scan of the abdomen demonstrated many bulky lymph nodes, the largest measuring 6 x 5 cm in high retrocaval position. This one caused a caval compression and an anterior dislocation of the left vein with a focal thrombosis from kidney level until the right common iliac vein.

From the right side: a huge retrocaval bulky lymph node under the renal vein level, then inferior vena cava and aorta, both isolated from other bulky lymph nodes.

PNET, pathological characteristics: (A,B) Histologic examination showed undifferentiated neoplasms composed of diffuse sheets, nests, and cords of noncohesive monomorphic small blue/basaloid cells (H-E: 100x, 200x). The neoplastic cells showed mild and focal immunoreactivity for (C) WT1 and (D) CD99.
