Marginal zone lymphomas are a group of slow-growing non-Hodgkin B-cell lymphomas. This type of lymphoid tissue tumors occur extremely rare in larynx. Since the first description by Diebold et al in 1990, less than 50 cases marginal zone lymphomas of the larynx have been reported [1, 2]. We present a case report of a 66-year-old woman, admitted in April 2012 to an ENT Ward in Polanica Zdroj hospital in order to perform a biopsy of lesion present in larynx since at least 2 years. Patient presented with hoarseness, mounting dyspnoea and history of recurrent inflammation of larynx and trachea. Histopathologic examination revealed B-Cell Marginal Zone Lymphoma. The patient was sent to undergo further hematological treatment (R-CHOP regimen chemotherapy), which was followed by a complete remission. It is important to emphasize that it was the 3rd biopsy of the lesion taken in 2 years time (since 2010) preceded by two such procedures in another clinical ENT Ward in Poland. The microscopic examination results of the previous biopsies were described as indicative more of an inflammatory lesion although both of them were said to be hard to evaluate. This shows the diagnostic difficulties that biopsy itself or its microscopic interpretation might bring.

Introduction: Malignant lymphoma (ML) is a neoplasm caused by clonal expansion of undifferentiated B, T and NK-lymphoid cells. WHO classification divides lymphomas into two main types, i.e. Hodgkin lymphoma (HL), and non-Hodgkin lymphoma (NHL), with numerous subtypes. The majority of MLs are localized in lymph nodes, but extranodal locations are also possible. MLs represent approximately 3-5% of all malignant neoplasms in Poland, but their incidence has been increasing in recent years, especially in young patients. The objective of the study was to evaluate clinical manifestations and diagnostic process in patients with malignant lymphomas of the head and neck region as diagnosed in the Department of Otorhinolaryngology of the Medical University of Lodz in years 2013-2017. Material and method: 30 patients diagnosed with malignant lymphomas of the head and neck region at the Departbadament of Otorhinolaryngology of the Medical University of Lodz in 2013-2017. Results: The study group consisted of 8 cases of nodal lymphomas and 22 cases of extranodal lymphomas. In 29 cases B-cell lymphomas were diagnosed. The most common symptoms included lymphadenopathy or neck tumor. Other symptoms were associated with the location of tumors in particular body organs. The diagnosis was based on histopathological examination of biopsy (needle or surgical) samples. Conclusion: Malignant lymphomas should be taken into account during differential diagnosis of the tumor or lymphadenopathy of the neck. The diagnosis is difficult because of the nonspecificity of symptoms and the need for interdisciplinary cooperation of many specialists.
