Anaplastic large cell lymphoma (ALCL) is recognized as a distinct subtype of non-Hodgkin’s lymphoma in the Revised European American Lymphoma (REAL) classification. Immunophenotypically it is either T-cell or null cell type along with almost universal expression of CD30+. Sinonasal tract is a rare site. We have seen a 50-year-old female who presented with a mass in the right maxillary antrum and nasal cavity. Initially she was misdiagnosed as poorly differentiated carcinoma and underwent maxillectomy. But histopathology of the resected specimen revealed the diagnosis of ALCL based on the light microscopic and immunohistochemical features. She received CHOP chemotherapy and continues to show complete remission at 18 months follow-up. The possibility of ALCL should be considered in the differential diagnosis of undifferentiated tumors of the sinonasal tract as surgery can be avoided if a proper diagnosis is made.
