FNA diagnosis of secondary malignancies in the parotid gland: over 20 years of experience from a single institute.

ABSTRACT:

Introduction

Metastatic solid tumors account for a significant portion of malignancies in the parotid gland. Fine-needle aspiration (FNA) is a primary tool to diagnose these tumors.

Materials and methods

We retrospectively reviewed 134 FNA cases of metastatic solid tumors affecting the parotid gland, spanning from 2000 to 2023 at our institute. We summarized the medical histories, cytology diagnoses, correlations with surgical resections, clinical treatments, and follow-up outcomes.

Results

The patient cohort included 107 male and 27 female patients, with a median age of 71 years (range: 4-96 years). Eighty-five percent of metastases (113 of 134) originated from head and neck (H&N) malignancies, comprising 66% from cutaneous source and 19% from mucosal sites. The most
