Hepatic adenoma within a spindle cell carcinoma in a woman with a long history of oral contraceptives.

Abstract

The case of a young woman is presented who had a long history of oral contraceptive use and who was found to have a focal hepatic adenoma within a large spindle cell carcinoma of the liver. The pleomorphic tumor is positive for keratin and alpha 1-antitrypsin by immunohistochemistry, has intracellular lumina by electron microscopy, a moderately high thymidine labeling index, and is negative for estrogen and progesterone receptors. A review of the literature concerning liver tumors occurring in young patients indicates that there is an underlying disturbance of the hormonal milieu in all instances reported. The prognosis is widely variable and unpredictable.

Clinical and laboratory evidence of an association of oral contraceptive (OC) use with the subsequent development of benign and malignant hepatobiliary neoplasia is growing. The authors present a case in which an adenoma within a large, multicentric anaplastic spindle cell carcinoma occurred in a woman with a long history of OC use. The patient, a 38-year-old gravida 2, para 2, was diagnosed following low-grade fevers and right upper quadrant pain. A partial hepatectomy was performed with no complications; however, a follow-up examination 2 months later revealed widespread intra-abdominal tumor recurrence histologically identical to the original tumor. Immunostaining for alpha 1 antitrypsin and keratin was strongly positive in tumor cells, indicating a biliary derivation. Electron microscopy indicated an epithelial derivation as well, including the presence of intracellular lumens, intermediary filaments, and numerous intercellular junctions. Estrogen and progesterone receptors were negative in the tumor. The tritiated thymidine labeling index was 5.05%, with an estimated potential doubling time of 11 days. This woman had no history of hepatitis, no family or personal history of neoplasms, and no known hepatotoxin exposure. The only medication used by the patient was Norlestrin, an OC containing 1 mg norethindrone and 50 mcg ethinyl estradiol that she had taken continuously for the past 8 years.
