A rare case of orbital metastasis from carcinoma of the prostate in a 76-year-old man who presented with pain in his left eye, mild proptosis and reduced visual acuity is reported. Cranial CT scanning demonstrated large bone metastases in the left orbit. The patient underwent orbital evisceration. The histopathological studies that were based on the morphological and immunohistochemical findings confirmed the histological diagnosis of orbital metastasis arising from prostatic carcinoma with neuroendocrine features.

Introduction: Superior orbital fissure syndrome (SOFS) is a rare condition that involves damage to multiple structures within the superior orbital fissure, often caused by trauma, inflammation, or tumors. Lung adenocarcinoma, known for its propensity to metastasize, can lead to orbital metastases, which can manifest as SOFS. This case underscores the diagnostic and therapeutic challenges associated with such rare metastatic presentations.

Case Presentation: Both cases demonstrated sheet-like or focal nested architecture and comprised epithelioid cells with abundant clear to eosinophilic cytoplasm and vascular stroma.

Adenoid cystic carcinoma (ACC) is a rare and lethal malignancy that originates in secretory glands of the head and neck. A prominent molecular feature of ACC is the overexpression of the proto-oncogene MYB. ACC has a poor long-term survival due to its high propensity for recurrence and protracted metastasis.
