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 the salivary glands~~: one of the most common malignancies of the~~ ~~submandibular~~ ~~and~~ ~~sublingual glands~~
- adenoid cystic carcinoma of the lacrimal glands
- hard palate
- nasopharynx
- rarely reported: 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
- adenoid cystic carcinoma of the Bartholin glands
