Primary Anaplastic Large Cell Lymphoma of the Nasal Cavity: A Case Report

Introduction: Anaplastic large-cell lymphoma occurring in the nasal cavity is a rare disease. The latest World Health Organization (WHO) Classification recognizes three distinct subtypes: primary systemic anaplastic lymphoma kinase positive been our case, primary systemic anaplastic lymphoma kinase negative and primary cutaneous types. Through this case study, we focus on the clinical presentation, treatment and prognostic characteristics of this pathology. Case Presentation: We report the case of a patient aged 32 years, who presented for seven months a runny nose associated with swelling of the face on the left side, without peripheral lymphadenopathy or general signs. A Blondeau scanner objectified a total filling of the frontal and left maxillary sinus, and a filling of the left nasal cavity. Complete resection of the tumor was performed. Histological examination was in favor of anaplastic large T-cell lymphoma anaplastic lymphoma kinase positive. The patient was stage IE according to Ann Arbor classification, with an International Prognostic Index estimated at one. Thus, the patient received six cycles of CHOP chemotherapy. Currently, he is in good loco-regional control with a decline of three months. Conclusion: The rarity of this case lies partly in the lymphomatous localization in the nasal cavity, and secondly in the anaplastic histology. It poses a diagnostic problem. So, we conclude that in case of any symptom of nasal cavities, it is necessary to explore and possibly biopsy if tumor, before surgery, because lymphomas are chemosensitive disease.
