Primary pulmonary choriocarcinoma: a case report.

Background: Primary pulmonary choriocarcinoma (PPC) is an extremely rare clinical entity. In contrast with gestational trophoblastic tumors that show an extreme sensitivity for chemotherapy, extragonadal choriocarcinomas are mostly unresponsive to surgical and chemotherapeutic treatment and are associated with poor prognosis. The reason non-gestational choriocarcinomas behave so differently from gestational tumors is unknown.

[Metastatic endophthalmitis following lung transplantation].

Intraocular septic--bacterial, viral or fungal--metastasis originating from an infectious focus is very rare but serious complication. The authors performed one enucleation and one evisceration on two patients because of endophthalmitis secondary to pulmonary infection following lung transplantation. The pathogens were Pseudomonas aeruginosa and Mycobacterium xenopi respectively.
