Adenoid cystic carcinomas are generally considered low grade ⁴. The tumours have a notable tendency for perineural spread.

Location

They have a wide distribution and mainly occur in relation to the airways, lacrimal glands and breasts. Reported locations include:

head and neck
- adenoid cystic carcinoma of salivary glands: one of the most common malignancies of the submandibular and sublingual glands
- adenoid cystic carcinoma of the lacrimal glands
- hard palate
- nasopharynx
- eyelid ⁵
adenoid cystic carcinoma of the breast ²
tracheobronchial tree/respiratory tract
- adenoid cystic carcinoma of the tracheobronchial tree
  - second most common primary malignant tracheal neoplasm (after squamous cell carcinoma) ⁴
  - previously also called a cylindroma in this location ⁴
- adenoid cystic carcinoma of the lung
pelvis
- uterine/cervical
