Castleman's Disease of the Parotid Gland: A Case Report

Castleman's disease (CD) is a very rare disorder characterized by non-neoplastic growths in lymph nodes in any body regions, although over 60% of cases are located in the mediastinum. The head and neck is the second most commonly involved site, with up to 14% of cases. Of these, nearly 85% are located in the neck. These lesions rarely occur in the salivary glands. Clinically, CD can be divided into unicentric and multicentric forms. We report an unusual case with unicentric CD presenting as a parotid tumor in a 34-year-old woman. The lesion was found coincidentally during routine cranial magnetic resonance imaging in the absence of symptoms such as swelling or a mass in the parotid region.
