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 lacrimal glands
- hard palate
- nasopharynx
- eyelid ⁵
adenoid cystic carcinoma of breast ²
tracheo-bronchial tree / respiratory tract
- adenoid cystic carcinoma of tracheo bronchial tree
  - second most common malignant primary tracheal neoplasm (after squamous cell carcinoma) ⁴
