Purpose: Metastatic neoplasms to the ocular surface are extremely rare. Here we describe a case of initial metastasis from undifferentiated carcinoma of the parotid gland to this area.
Methods: Case Report
Results: A 56-year-old man developed to a simultaneously limbal and parotid gland masses in his left side. He underwent an excisional biopsy of limbal mass and parotidectomy and systemic evaluation. Histopathologic examination, in multislice sections of the both limbal and parotid masses, disclosed an undifferentiated carcinoma of both sites. Further evaluation revealed no other site of involvement and metastasis. The patient underwent systemic chemotherapy and local radiotherapy for parotid gland tumor.
Conclusion: Distal metastasis from undifferentiated carcinoma of the parotid gland to ocular surface is a very rare episode and to the best of our knowledge has not been previously reported. This is the first report of the manifestation of metastasis from undifferentiated carcinoma of parotid gland origin to the limbus. The ocular surface mass may be the initial manifestation of metastasis from this origin and should be considered in the differential diagnosis of a metastatic limbal tumor.
