Liver perivascular epithelioid cell tumor in a patient with systemic lupus erythematosus.

INTRODUCTION: Perivascular epithelioid cell tumor (PECOMA) is a rare mesenchymal neoplasm which expresses both myogenic and melanocytic markers showing a benign course,although malignant tumors have also been reported. To date there are approximately 33 cases of published hepatic pecomas.

PRESENTATION OF CASE: We describe a 47-year-old man with a 27-year past medical history of systemic lupus erythematosus (SLE) who underwent left liver lobectomy due to a liver pecoma. His postoperative course complicated with infection, thrombosis of hepatic artery and liver ischemia as well as drug fever.

DISCUSSION: Treatment protocol especially for hepatic PECOMA has not reached a consensus although surgical resection is the preferred therapy.

CONCLUSION: This is the first case of coexistence of liver pecoma and SLE.
