Surgical treatment of toraco-abdominal teratoma diagnosed in utero, approached with mini-invasive technique: a case report

Thoracic tumours of childhood arise either in the mediastinum, or from the chest wall and rarely from the lung parenchyma. Mediastinal teratoma occur in the anterior mediastinum and are usually very large at presentation; initial treatment is under discussion, but it appears that surgical excision and histological examination are the treatments of choice and it will determine whether the lesion is benign or malignant. The authors report a case of thoracic-abdominal teratoma, diagnosed in utero, and treated successfully with thoracoscopy and laparoscopy. No complication was described in short follow up, and the child was discharged in day 8th postoperative day. Histology showed mature teratoma. Follow-up at one year: no evidence of recurrence. Due to the rarity of multifocal teratoma in newborns, author believe that mini-invasive technique was useful to stage histological the mass, giving the opportunity to plans a second stage in treatment of the patient. Day of hospitalization resulted shorter in both surgical approaches, and discomfort less for the thoracic approach. This staging must be anyway planned, in the way of prenatal counselling and in the perinatal period, with the team involved in the procedure, that include anaesthetists, oncology staff, obstetricians, neonatologists and pediatric surgeons. It is mandatory in cases like the one reported that a multisciplinary team manage the patients and expert surgeons, especially in minimal invasive surgery, make the adequate plans.
