Anaplastic large cell lymphoma

Anaplastic large cell lymphoma (ALCL) or Ki‐1 lymphoma is a recently described and distinctive non‐Hodgkin's lymphoma. Cervicofacial adenopathy caused by ALCL may mimic involvement by metastatic carcinoma or other malignancies common to the head and neck. A case in which ALCL was originally interpreted as metastatic nasopharyngeal carcinoma is presented. The clinicopathologic features of this uncommon entity are discussed.
