title: Oncocytoma of the lacrimal gland: case report and review of the literature.
abstract: OBJECTIVE
  Oncocytomas of the lacrimal gland are rare tumors. We report the eighth case in the literature.
  
  
  METHODS
  Interventional case report and literature review.
  
  
  METHODS
  Complete ophthalmologic and systemic examination followed by excisional biopsy and histopathologic examination.
  
  
  RESULTS
  A 40-year-old Hispanic woman was evaluated for a right-sided upper eyelid edema and pain on ocular motility. A month earlier an outside ophthalmologist had performed a conjunctival biopsy that disclosed chronic inflammation. Computed tomography and magnetic resonance imaging of brain and orbit demonstrated a right intraorbital extraconal soft tissue density mass that involved the lacrimal gland, upper eyelid and encroached both the superior oblique and superior rectus muscles. Histopathology showed a benign oncocytoma that replaced most of the lacrimal gland.
  
  
  CONCLUSIONS
  Although rare, oncocytomas should be included in the differential diagnosis of any lacrimal gland tumors.
