Low-grade intraductal carcinoma of the parotid gland: Is it low-grade or locally aggressive?

Low-grade salivary ductal carcinoma is a salivary gland tumor with clinically indolent behavior, characterized by intraductal growth. From 1996 to 2019, 54 case reports of Low-Grade Intraductal Carcinoma (LGIDC) were published in the literature. In the present article, we introduce a patient in our clinic who underwent surgery due to a diagnosis of LGIDC, about whom we make new clinical comments. A 75-year-old male patient presented to our clinic with a complaint of a mass in the right parotid area. After multiple biopsies, magnetic resonance imaging (MRI), and operations, the patient health is fine and patient's follow-up continues, now in the postoperative 1st year, and there is no relapse sign on physical examination and MRI. After all, according to our clinical findings and observations, we thought that this tumor could possibly be considered a locally aggressive tumor that does not metastasize, similar to a basal cell carcinoma.
