Slow Growing Palatal Swelling- A Diagnostic Dilemma A Case Report and IndepthReview of Contemporary Literature

Abstract

The adenoid cystic carcinoma is a relatively rare epithelial tumor more than half of these occur in the parotid and submandibular glands. The most common intraoral site is the palate. Its peak incidence occurs predominantly among women, between the 5th and 6th decades of life. The clinical and pathological findings typical of this tumor include slow growth, perineural invasion, potential local recurrence and distant metastasis. Histopathologically it is composed of basaloid cells with primarily myoepithelial/basal cell differentiation. It presents three patterns, cribriform, tubular and solid; the solid type is related to a poor prognosis contrary to the cribriform type, which has a better prognosis. We presented herein the case of a 26 year old male patient who presented a palatal lesion with an indepth review of literature. 2 .It comprises less than 1% of all malignancies of the head and neck and is the fifth most common malignancy of salivary gland origin, representing 10% of salivary gland malignancies 3 .As per ICD-O code 8200/3.The parotid and submandibular glands are the two most common sites for ACC accounting for 55% of the cases. The long natural history of this tumor, its propensity for perineural invasion, and its tendency for local recurrence are well known 3 .Its peak incidence occurs predominantly among women, between the 5th and 6th decades of life 4 .We present a case of ACC of the hard palate minor salivary glands, and a literature review on its clinical, histopathological and management aspects. 5 is a benign neoplasm which is commonly encountered in the parotid gland. At times they can also develop in minor salivary glands of the palate and lips. The majority of minor salivary gland tumors are malignant. It may occur at any age, but mainly they affect patients in the 4 th
