Epidermoid carcinoma (also known as squamous cell carcinoma) of the parotid gland is more prevalent among the elderly, as are other head and neck tumors. In most cases it is observed either as a nodal metastasis of a primary tumor that drains into the parotid area or as a direct extension of a tumor that has originated in the upper dermis. Primary epidermoid carcinomas arising directly from the parotid gland are extremely rare. Similarly, secondary invasion of the orbital region by a neighboring tumor is more common than primary epidermoid carcinoma of the orbit, which is also rare. In this article, we discuss the diagnosis and treatment of a rare case of epidermoid carcinoma simultaneously invading the parotid gland and the orbit.
腮腺表皮样癌（也称为鳞状细胞癌）在老年人中比其他头颈肿瘤更为常见。在大多数情况下，它表现为引流至腮腺区域的原发性肿瘤的淋巴结转移，或起源于上真皮层的肿瘤的直接蔓延。直接起源于腮腺的原发性表皮样癌极为罕见。同样，邻近肿瘤对眼眶区域的继发性侵犯比眼眶原发性表皮样癌更为常见，眼眶原发性表皮样癌也很罕见。在本文中，我们讨论了一例罕见的同时侵犯腮腺和眼眶的表皮样癌的诊断和治疗。
