Ectopic hepatocellular carcinoma of the diaphragm.

Ectopic hepatocellular carcinoma (HCC) is very rarely reported. It may occur at various sites. To the best of our knowledge, only one case of ectopic HCC of the diaphragm has been reported. We present another such case with invasion to the lung. Subtotal resection of the left hemidiaphragm, wedge resection of the lung (left lower lobe), and splenectomy were undertaken. Postoperative course was unremarkable; the patient received two courses of adjuvant chemotherapy with cisplatin, VP-16, and bleomycin 1 month later. Follow-up computed tomography and ultrasound were performed 8 months later; there was no local recurrence or distal metastasis.
