Pectus excavatum is the most common congenital deformity of the chest wall. The most frequently used techniques include Ravitch (costochondral resection) and Nuss (minimally invasive pectus repair of pectus excavatum [MIRPE]). The Nuss technique includes using temporary metallic bars without costochondral resection to correct the chest wall deformity. Modified MIRPE can be learned easily and performed safely with few complications. There are no reports of successful MIRPE in Iran, although the Ravitch technique is well known. In the present study, we report the first Iranian experience with the modified Nuss procedure in 5 patients with pectus excavatum (age range=13-48 y). All the patients suffered from low self-esteem, and one of them complained of low exercise capacity and occasional chest pain. With single-lung ventilation and sternal elevation, an introducer was entered into the right thoracic cavity and retrosternal tunneling was performed under thoracoscopic vision. The introducer was passed to the left thoracic cavity and exited on the left thoracic wall. A titanium plate bar was implanted and fixed with stabilizers. There were no cases of mortality, and all the patients were discharged in good conditions within 2 weeks. Postoperative complications consisted of 1 case of pneumothorax and 2 cases of fixed bar protrusion. The present case series indicated that a skilled thoracoscopic surgeon is able to do the Nuss procedure in Iranian patients with symmetrical pectus excavatum with few complications. However, mixed or redo cases require more expertise.

Placenta Site Trophoblastic Tumor and Choriocarcinoma from Previous Cesarean Section Scar: Case Reports.

Iran J Med Sci 2018 Jul;43(4):426-431

Choriocarcinoma and placental site trophoblastic tumor (PSTT) are rare varieties of gestational trophoblastic disease (GTD). PSTT alone constitutes about 1-2% of all trophoblastic tumors, which presents at early reproductive age and the serum beta-hCG level is much lower than choriocarcinoma. This tumor usually invades the myometrium and its depth of penetration is a prognostic factor. The first case report is regarding a 33-year-old woman with vaginal bleeding 3 months after abortion. The ultrasound exhibited heterogeneous and hypervascular mass related to previous cesarean scar. Serum beta-hCG level was 67 mIU/ml and chemotherapy was administered. However, due to severe vaginal bleeding and no regression in mass size, total abdominal hysterectomy was performed. Histopathological examination and IHC staining confirmed PSTT from previous cesarean section. The second case report is regarding a 33-year-old woman with cervicoisthmic choriocarcinoma, which was mistaken as cesarean scar pregnancy. The ultrasonography and elevated serum beta-hCG level suggested cesarean scar pregnancy. The patient was treated with methotrexate without any effect. Eventually, cervicoisthmic choriocarcinoma was detected after hysterectomy. A diagnostic error was made leading to possible uterus perforation along with incorrect chemotherapy that resulted in a life-threatening condition. It is concluded that PSTT and choriocarcinoma are the two important differential diagnoses of sustained elevated beta-hCG when imaging evidence is also suggestive. Although PSTT and cervicoisthmic choriocarcinoma are rare, they do exist and are on the rise.
