Abstract

Background: The cytologic findings of teratocarcinoma of the testis have not been well described. We report the cytological findings of such a case.
Case: The patient was a 29-year-old male with a right testicular mass, measuring 8.5×7.5×8.0 cm in diameter. The imprinted specimen from the cut surface of the mass revealed large atypical cells showing pseudopapillary and glandular clusters or individually scattered appearance. Their cell membrane was indistinct, and the cytoplasm was granular and weakly stained lightgreen. The chromatin pattern was coarse granular. Eosinophilic and irregularshaped nucleoli were noted. In addition, a few sheets composed of small, non-atypical glandular epithelium were observed. There were no squamous epithelium, hair, bone, or cartilage.
Conclusion: Germ cell tumors may be composed of several types of tumor cells, and therefore cytologic preparations should be observed carefully.
