Pleomorphic adenoma is the most common benign neoplasm of salivary glands. Their common location is in parotid gland, however, a lower percentage of these tumors might occur in minor glands. The epidemiology of this tumor shows that adults are the most affected, with rare occurrence in children or adolescents. We present the case report of pleomorphic adenoma located on the palate of a 10 year old. Excisional biopsy of the lesion followed by histopathologic examination of the biopsy specimen revealed ductal structures surrounded by plasmacytoid mioepithelial cells within a myxoid stroma, the final diagnosis corresponded to Pleomorphic Adenoma. Early detection and excision of this lesion in children are important to minimize potential recurrences or malignant transformation.
This therapy is a safe, innovative, and useful tool and can be of great assistance especially in complex craniofacial wounds, but it poses some problems such as intricate contours and orifices of the head and neck region, painful dressing changes, and remarkable costs.
Necrotizing sialometaplasia is a rare, benign, self-limiting, necrotizing process involving the minor salivary glands, mainly the mucoserous glands of the hard palate. It is thought to be the result of an ischemic event of the vasculature supplying the salivary gland lobules. Some predisposing factors such as smoking, use of alcohol, denture wearing, recent surgery, traumatic injuries, respiratory infections, systemic diseases bulimia, and anorexia have been described. Herein we present a case of necrotizing sialometaplasia of the hard palate in a patient without known predisposing factors, in our opinion, resulting from the use of topical anti-inflammatory drug. After diagnosis, the patient underwent treatment with chlorhexidine gluconate and a full palatal acrylic guard to protect the exposed bone from food residues during meals. After the sixth week the lesion regressed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
