Workup

Imaging Studies

  • Neuroimaging studies can be of great assistance in making the correct diagnosis.
  • Computed tomography (CT) scan of benign epithelial lesions, such as pleomorphic adenomas, reveals a well-circumscribed, pseudoencapsulated lesion in the superotemporal fossa.
  • Characteristic bony changes include expansion and remodeling in the lacrimal fossa without evidence of bony invasion or erosion.
  • In contrast, malignant epithelial lesions, such as adenoid cystic carcinoma, usually present as an irregular mass, producing bony erosion (70%) and occasional calcification (20%).
  • Lymphoproliferative lesions usually are eccentric in shape with significant contrast enhancement.

Other Tests

  • Immunohistochemistry may be helpful in distinguishing between inflammatory, benign, and malignant lymphoproliferative lesions. Immunohistochemistry is a laboratory modality that uses special markers to demonstrate the presence of specific antigens in target tissues.
  • Benign inflammatory lesions (pseudotumor) have a polyclonal morphology, whereas the lymphoid lesions tend to be monoclonal.

Histologic Findings

Histologic examination of pleomorphic adenomas reveals evidence of both epithelial and mesenchymal differentiation. Proliferation of benign epithelial cells usually is arranged in a double layer to form lumens. Stromal differentiation can be seen in the formation of bone and cartilage.

Adenoid cystic carcinomas are derived from duct cells, and they form spaces into which basement membranelike material is deposited. This confers a cribriform or "Swiss cheese" appearance to the tissue, although growth in tubules and nests also are recognized. Five histologic patterns have been observed in these lesions, as follows: (1) cribriform (the most common subtype), (2) sclerosing, (3) basaloid, (4) comedo, and (5) ductal. The basaloid type has the worst prognosis.
