Discharge Summary:

Patient Name: [REDACTED]

Medical Record Number: [REDACTED]

Admission Date: [REDACTED]         Discharge Date: [REDACTED]

Hospital Course:

The patient was admitted to our hospital for surgical treatment of two hepatic tumors. During the initial examination, the patient was found to have a history of hepatitis B and C viral infections, diabetes, and diabetic renal failure. The patient had a CT scan which revealed two hepatic tumors. The patient was diagnosed with small, regular, oval-shaped cells with mild atypia that formed the luminal structure. The postoperative course was uneventful and the patient was discharged on postoperative day 13.

Past Medical History:

The patient had a history of blood transfusion at the age of 6 years during surgical treatment for a traumatic left femoral fracture. He was diagnosed with hepatitis B and C viral infections at the age of 30 years and had a history of interferon therapy. He also had a history of diabetes, and hemodialysis was introduced for diabetic renal failure at the age of 49 years. He had no familial history.

Hospital Course:

The patient had a soft and flat abdomen without ascites. Laboratory tests showed low platelet and white blood cell counts, and elevated hemoglobin, albumin, and total bilirubin levels. The patient had Child-Pugh grade A with an indocyanine green retention rate of 4.9%. Hepatitis B virus antigen and hepatitis C antibody were positive. Serum alpha-fetoprotein was elevated at 126.0 ng/mL. Pre-contrast CT scans revealed two hypoattenuating hepatic lesions, and contrast-enhanced CT scans revealed that the tumor in one of the lesions was enhanced in the arterial phase, while the other lesion was not enhanced.

Diagnostic Findings:

Magnetic resonance imaging revealed similar findings of low signal intensity on T1-weighted images and high signal intensity on T2-weighted images for both the lesions. The preoperative diagnosis was multiple HCCs. However, CT findings were not typical of HCCs. Partial resections of both lesions were performed, and the tumors were found to be well-defined lesions of 8.0 mm and 14.0 mm, respectively. Pathological examination of tissue from one tumor revealed CoCC, while the tumor from the other lesion corresponded to moderately differentiated HCC. The pathological findings of each cancer resulted in T1aN0M0 stage I according to Union for International Cancer Control the 8th edition. The pathological findings of non-cancerous tissue showed liver cirrhosis.

Follow-up:

The patient was alive without recurrence 36 months after surgery.

Summary:

A 58-year-old Japanese man with a history of hepatitis B and C viral infections, diabetes, and diabetic renal failure was admitted to our hospital for surgical treatment of two hepatic tumors. The tumors were found to be well-defined lesions of CoCC and moderately differentiated HCC. The patient underwent partial resections, and the postoperative course was uneventful. The patient was discharged on postoperative day 13 and was alive without recurrence 36 months after surgery.
