Laparoscopic Findings of Metastatic Laryngeal Carcinoma of the Liver Histologically Simulating Hepatocellular Carcinoma

: A 77-year-old male was admitted to the department of Oto-rhino-laryngology of our hospital in 1989 with hoarseness due to laryngeal cancer. It was well treated with X-ray irradiation and could not be detected by computed tomography (CT) and Gallium (87Ga) scintigraphy at the time of his discharge from hospital, and his hoarseness also subsided. In November 1992, he noticed the hoarseness again with a gradual worsening. On admission to the same department, multiple space occupying lesions were detected in right lobe of the liver by abdominal ultrasonography (US) and CT. When he was transferred to our department, a US-guided aspiration biopsy showed a pathohistology mimicking hepatocellular-carcinoma with a multiple restiformation. Laparoscopy revealed multiple yellowish white flat lesions with an irregular margin, and aimed biopsy was performed to one of these lesions. Histology mimicked hepatocellular carcinoma with a few keratinocytes and a coiled structure and these were consistent with a diagnosis of metastatic epidermoid carcinoma. This is the first case report regarding laparoscopic observation of metastatic epidermoid carcinoma originating in the larynx.
