Introduction: Malignant tumors of minor salivary glands are relatively uncommon. In the larynx, ACC is extremely rare. These tumors are commonly arise in the subglottic region of larynx.
Materials and Methods: We present an unusual case of ACC in a 50 year old male. On laryngoscopic examination a growth was seen in the arytenoid region of larynx. An incisional biopsy was taken and sent for HPE.
Results: A tumor was seen in the submucosal region with typical cribriform pattern and myxoid matrix. A diagnosis of ACC was noted.
Conclusion: ACC is a very slow growing tumor but is notorious for local recurrence and distant metastasis. Hence caution is needed in such cases, especially when the tumor is seen beneath the mucosa. Failure of diagnosis ACC may lead to fatal outcome in some cases.

Keywords: Adenoid cystic carcinoma, Larynx, Prognosis.
