The combination of chronic pain, cystic changes, and calcification in a lacrimal gland fossa mass in an adult should suggest a malignant neoplasm, but a long-standing orbital cyst with calcification of its rim can produce the same features. If so, where and how many? Calcification, although more common in carcinomas, may be present in adenomas as well. Lesions of the lacrimal gland and fossa constitute about 5%–13% of all orbital masses confirmed by biopsy. Adenocarcinoma of the lacrimal glands is rare, with few cases reported in the literature since it was first described in 1996 1. Tumor (T): How large is the primary tumor?
