ABSTRACT

Background: The relationship between cancer and pregnancy accounts for 0.07% of gestational complications. This aspect makes treatment difficult and has a negative impact on pregnant patients. The primitive neuroectodermal tumor is a neoplasm related to Ewing’s sarcoma and its incidence is exceptional during pregnancy.
Clinical case: A 34-year-old patient, 36.3 weeks pregnant, who was admitted to the hospital unit due to abdominal pain radiating to the right lower limb. Physical examination revealed a large tumor in the right iliac fossa. The abdominal ultrasound showed an image compatible with a myoma. Magnetic resonance imaging revealed a mass of 16 x 13 x 17 cm, retroperitoneal, paravertebral, coinciding with neuroectodermal tumor, sarcoma and neurogenic tumor. The patient had eutocic delivery, without administration of epidural analgesia, from which a girl of 2950 g was born, and Apgar 8/9. An aspiration biopsy was performed with a thick needle, which reported a primitive neuroectodermal tumor. The treatment consisted of chemotherapy with VAC protocol (vincristine, dactinomycin and cyclophosphamide [14 cycles]) and adriamycin (6 to 8 induction cycles). He currently suffers from neuropathic pain in the right leg and remains in rehabilitation, with medical treatment.
Conclusions: Primitive neuroectodermal tumors are exceptional neoplasms during pregnancy. Complementary studies are required to know the exact relationship between this type of tumors and pregnancy, and in this way establish the appropriate treatment strategy.
