Association Between Secondary Peritoneal Hydatidosis and Peritoneal Carcinomatosis from Ovarian Cancer - A Case Report.

Peritoneal carcinomatosis from ovarian cancer is unfortunately a very common finding, especially in patients diagnosed in very late stages of the disease. Nonetheless, it is not the only pathological condition inducing a diffuse involvement of the peritoneum; other entities can have an infectious or miscellaneous origin. However, the association of peritoneal carcinomatosis and parasitic infection has never been reported so far. We present the case of a 50-year-old patient who had been submitted to surgery for a hepatic hydatid cyst. Four years later, the patient was diagnosed with disseminated peritoneal lesions, which proved to have both parasite and neoplastic origin. The patient was re-submitted to surgery, and debulking resection of all pathological lesions was achieved. Although it is very rare, the association of peritoneal carcinomatosis and peritoneal hydatidosis should be taken into consideration whenever the patient reports a suggestive medical history for those two pathological findings.
