title: Follicular dendritic cell sarcoma/tumor: 2 cases of a rare tumor of difficult clinical and pathological diagnosis.
abstract: The follicular dendritic cell sarcoma/tumor is a neoplasic proliferation of fusiform and ovoid cells with characteristic morphology and immunohistochemical pattern. The sarcoma/tumor term is designated due to the variability of the cytological status and, in many cases, its indeterminate clinical course. This report presents the 2 first cases seen at the Hospital General de México, OD (General Hospital of Mexico). The aim of this study is to contribute to the morphology and immunophenotype of this infrequent neoplasm, as well as discuss its differential diagnosis and clinical evolution.
