Bilateral Choroidal Metastasis as Initial Presentation of Parotid Gland Adenoid Cystic Carcinoma

Choroidal metastasis rarely reveals a primary cancer. At this stage, they are associated with multiple metastases. Adenoid cystic carcinoma also known as cylindroma is very rare and constitutes 1% of major and minor salivary glands malignancies. In the parotid gland, the ACC is relatively rare, constituting only 2–3% of all tumors. The purposes of this study are to report the first case of parotid gland adenoid cystic carcinoma metastatic to the choroid and discuss treatment approaches. The systemic prognosis of salivary gland ACC is poor, with frequent local recurrences and late distance metastases. Even though uncommon, ocular metastases should be considered, and plaque radiotherapy may be useful to treat these patients.
