Diagnosis and treatment of malignant lymphomas of parotid gland

Abstract

Based on our study results, the fine needle aspiration biopsy is not helpful in the diagnosis of the lymphomas of the parotid gland. Although rarely seen, lymphomas of the parotid gland should be considered in the differential diagnosis.

Follicular Lymphoma Mimicking a Benign Submandibular Gland Tumor

“…Non-Hodgkin's lymphoma derives from a lymphocyte progenitor and accommodates a heterogeneous group of exceptionally various malignancies. It could develoved from B-cells, T-cells, and NK cells [7,19]. Typically, NHL in the neck are from mature B cells origin [10,17].…”

“…According to their origin within or outside the lymph nodes, they can be subdivided into intranodal and extranodal types. Non-Hodgkin's lymphoma accounts for 2-4% of head and neck lymphatic tumors, 4-5% of all cancers [6,7,8], and 86% of lymphoma cases [9].…”

“…They are predominantly nodal and primarily found in the nasal cavity, paranasal sinuses, Waldeyer's ring, oral cavity, and salivary glands [7]. A salivary gland NHL is rare, most effective 5-10%, and represents 1.7% -3.1% of all salivary gland malignant tumors [2,3,6,7,9,10,11,12].…”

A salivary gland NHL is rare, most effective 5-10%, and represents 1.7% -3.1% of all salivary gland malignant tumors [2,3,6,7,9,10,11,12]. Rzepakowska et al reported 73.2% of nodal type lymphomas and 26.8% of extra-nodal type, which covered: submandibular glands, parotid glands, parapharyngeal space, hypopharynx, and larynx [13].…”
