Acute lymphocytic leukemia developing in a male with germ cell carcinoma: a case report.

A case of germ cell carcinoma (of presumed testicular origin) is described in which acute lymphocytic leukemia developed within nine months of the diagnosis. Possible relationships between the two neoplasms are discussed, as well as the need for continued observation of patients with germ cell tumors as they are living longer and may be at higher risk for developing a second cancer.
