Primary malignant lymphomas localized in salivary glands

Area of Science:

• Oncology
• Pathology
• Head and Neck Surgery

Background:

• Malignant lymphomas can affect salivary glands, necessitating detailed clinicopathological analysis.
• Exclusion criteria included myoepithelial sialadenitis and Sjögren's syndrome to focus on primary salivary lymphomas.

Purpose of the Study:

• To investigate the morphological and clinical characteristics of primary malignant lymphomas in the salivary region.
• To determine the frequency of different lymphoma subtypes and their origins within the salivary glands.

Main Methods:

• Morphological investigation of biopsies from 25 patients with salivary region malignant lymphoma.
• Analysis of clinical findings, including tumor location and disease stage.

Main Results:

• Non-Hodgkin's lymphoma was diagnosed in 21 cases, Hodgkin's disease in 4, all at stages I or II.
• The centroblastic-centrocytic type was the most frequent malignant lymphoma, observed in 15 cases, often with sclerosis.
• Lymphomas originated in intraglandular lymph nodes in 8 patients, possibly in 10 others.

Conclusions:

• Primary salivary region lymphomas are predominantly Non-Hodgkin's lymphomas, with the centroblastic-centrocytic type being most common.
• The majority of cases presented at early stages (I or II), contributing to a relatively favorable prognosis.
