Spontaneous rupture of hepatic metastasis from small cell neuroendocrine carcinoma of maxillary sinus.
BACKGROUND
Small cell neuroendocrine carcinoma of the maxillary sinus, a rare malignant tumor, has a poor prognosis because of its high incidence of metastasis. Moreover, metastatic cancer-induced hepatic rupture, characterized by hemoperitoneum, is infrequent, although several lines of evidences have reported that a wide variety of other neoplasms can cause this usually fatal manifestation.


METHODS
We now present the first case of a 49-year-old man with spontaneous rupture of hepatic metastasis from small cell neuroendocrine carcinoma of the maxillary sinus and ultimately resulted in massive intraperitoneal bleeding, which was successfully controlled by subsequent surgery (partial hepatectomy). The postoperative clinical manifestation of the patient was uneventful. He was discharged on the 16th day after operation and without any complication.


CONCLUSIONS
Small cell neuroendocrine carcinoma of the maxillary sinus is very scarce and unfortunately has a poor prognosis. It has potential to cause spontaneous metastatic rupture which can elicit fatal hemorrhage. Emergency surgery is effective, although the long-term outcome is still unsatisfactory.
