[Convoluted nuclear cell malignant lymphoma in the infant--report of 2 autopsy cases]

Two autopsy cases of malignant lymphoma characterized by convoluted nuclear cells are presented. The two cases were infants under two years of age. One of the patients had a mediastinal tumor, both had marked lymph node involvement and were complicated with leukemia in the late course of the disease. High power and oil immersion microscopy showed that the surface of the nuclei in the neoplastic cells were convoluted in form of cerebral gyrus or mulberry. Though the typical convoluted nuclear cell being important morphologically, clinical history and histologic feature must be considered in the diagnosis of this tumor.
