Adenoid Cystic Carcinoma of the Buccal Mucosa with Rare Delayed Frontal Bone Metastasis: A Case Report
Authors
Abstract:
Adenoid cystic carcinoma (AdCC) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). About 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). Three clinically obvious characteristics of AdCC include slow growth rate, perineural invasion and high incidence of distant metastasis (1). The most commonly-affected sites of distant metastasis are bone, liver and brain, followed by lungs (2). Lymph node metastases are rare; The most common sites involved by hematogenous spread are lungs (2). This is a report about a patient with a rare form of AdCC on buccal mucosa with an unusual metastasis to the frontal region after a two-year follow up.

Adenoid cystic carcinoma also known as cylindroma is a rare tumor, accounting for only 1% of all malignant tumors of the oral and maxillofacial region. It accounts for 22% of all salivary gland malignancies and involves both major and minor salivary glands but the percentage for involvement of minor salivary gland is more than that of major salivary glands. 1 It is a slow growing tumor and is o...
full textAdenoid Cystic Carcinoma of the Tongue: A Rare Case Report
Adenoid cystic carcinoma is a malignant neoplasm arising from the salivary glands. The most striking feature of this tumor is that it is locally aggressive, with perineural invasion, tendency to metastasize, high recurrence rates. The parotid gland is the most commonly affected site in the head and neck region, tongue being relatively rare. The current study presents a rare case of 6 years old ...

Adenoid cystic carcinoma (ACC) is usually a slow growing but highly malignant neoplasm with a remarkable capacity for recurrence. It mainly affects salivary glands, palate and is rare in the nose and paranasal sinuses. A case report of 38 years old male with ACC of left nasal cavity who presented with gradually progressing left sided nasal obstruction is presented here. The CT scan showed mass ...
