[Fanconi's anemia with squamous cell carcinoma--a case report and a review of literature].

A 39-year-old woman was admitted to our hospital complaining of hemosputum and right neck swelling. Pharyngography, neck CT scan and laryngoscopy revealed moderately differentiated squamous cell carcinoma of the right pyriform sinus. After series of examinations, it was found that she had pancytopenia, hypoplastic bone marrow, hyperpigmentation of the skin, cardiac anomaly, small stature, hypogonadism, chromosomal aberrations and consanguinity in her parents. These findings suggested that she was the congenital aplastic anemia, that is Fanconi's anemia, variant form. Although pepleomycin and corticosteroids were administrated for the treatment of squamous cell carcinoma and aplastic anemia, she died of cardiovascular shock due to massive hemorrhage. Flow cytometric analysis of squamous cell carcinoma showed an unusual aneuploidy DNA histogram. This is the first report on Fanconi's anemia with squamous cell carcinoma in Japan. It is said that chromosomal aberrations and impairment of DNA cross-links repair may play an important role developing of malignancy in Fanconi's anemia.
