A Rare Case of Metastatic Adenoid Cystic Carcinoma in the Liver: A Case Report

Adenoid cystic carcinoma (ACC) is among the most common primary malignant tumors of the salivary glands. The parotid, submandibular, and minor salivary glands are the predominant sites. Clinical presentation includes a slow-growing mass, often accompanied by pain and paresthesias. Distant spread of the tumor is common - most frequently to the lungs, followed by the bones and other sites such as the liver, brain, and soft tissue. Metastatic ACC involving the liver is exceedingly rare. Given the uncommon occurrence of hepatic metastasis in ACC, we present the case of a 54-year-old female with metastatic involvement of both the lungs and liver.
