Case report: primary cystic keratinizing squamous cell carcinoma of the liver in a patient with treated nasopharyngeal carcinoma.
Primary squamous cell carcinoma of the liver is very rare; only 18 cases have been recorded. In the present report we document an additional case who had a unique history of stage III non-keratinizing nasopharyngeal carcinoma treated with a full course of radiotherapy in July 1993. Two small hypoechoic cyst-like lesions in the left hepatic lobe were identified at the same time. In July 1995 the 50-year-old patient reported to be suffering from abdominal fullness and tenderness. A large hypodense tumour was demonstrated in the left hepatic lobe by abdominal echography. The patient was diagnosed as having metastatic carcinoma and received two courses of pre-operative chemotherapy followed by left lobectomy of the liver and resection of adherent tissues on 9 August 1995. Pathological study demonstrated a larger hepatic cystic keratinizing squamous cell carcinoma, which most likely arose from a solitary hepatic cyst. Tumour seedings, probably secondary to tumour rupture, were also revealed on the omentum, peritoneum and diaphragm. However, regional lymph nodes were fee of tumour. Systemic work-up failed to demonstrate evidence of local recurrence of nasopharyngeal carcinoma, metastatic lesion or any second primary tumour site.
