Blastic Plasmacytoid Dendritic Cell Neoplasm: An Uncommon Entity To Consider In The Differential Diagnosis Of Cutaneous Lymphoma

Cutaneous lymphomas are encountered infrequently in general surgical pathology practice, and the broad array of pathological entities poses a diagnostic challenge. Integration of clinical information, results of additional laboratory investigations, and an extensive immunohistochemical panel are essential in arriving at the correct diagnosis. We present a case of blastic plasmacytoid dendritic cell neoplasm that occurred in an unusual clinical setting. This case highlights the need for a broad differential diagnosis and an extensive immunohistochemical workup when approaching a cutaneous lymphoma.
