A primary lymph node malignancy with features suggestive of dendritic reticulum cell differentiation. A report of 4 cases.
Four cases are described of a nonlymphomatous primary lymph node malignancy characterized by the proliferation of oval and spindle cells, occasionally multinucleated, and arranged in a nesting, swirling, and storiform pattern. The combination of light-microscopic, ultrastructural, and immunohistochemical features suggests that these tumors might be derived from dendritic reticulum cells.
