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.
