Seven examples of an unusual hyalin degenerative change in the walls of blood vessels are discussed. We believe this is a localized phenomenon, not connected to systemic vascular disease. Inflammation is usually present, and in each case a dental procedure had previously been performed. Dental extraction was the most common procedure. Giant cells of the(More)
A prospective, double-blind study compared the effectiveness of sucralfate suspension with diphenhydramine syrup plus kaolin-pectin in reducing severity and pain of radiation-induced oropharyngeal mucositis. Fourteen patients who received at least 4600 cGy to the oral cavity used one of the mouth rinses four times a day, beginning at 1600 cGy. Data were(More)
A workshop to discuss primary oral melanomas was convened at the annual Western Society of Teachers of Oral Pathology meeting in Bannf, Alberta, Canada. Fifty oral melanomas, identified from the files of the participants, were reviewed in order to better understand the clinical features, histologic spectrum, and natural history of these perplexing lesions.(More)
A case of minor salivary gland clear cell adenocarcinoma of the palate with metastasis to the lungs in a 53-year-old female is presented. Histologically, the cells were characterized by glycogen rich clear cells arranged in solid nests, trabeculae, surrounded by hyalinized fibrous stroma. We believe this represents an aggressive form of this type of tumor.
Four HIV-positive patients with herpes simplex virus and cytomegalovirus coinfected oral ulcers are presented. All patients had persistent oral pain associated with nonhealing mucosal ulcers. Lesions occurred on the palate, retromolar pad, tongue, and lip, and the clinical appearance of the ulcers was nonspecific. Histologic and immunohistochemical stains(More)
Hyaline ring-like structures are often encountered during microscopic evaluation of inflamed tissues from the oral cavity. The exact etiology remains unknown. Two theories exist. One favors intrinsic origin, most likely collagen, while the other suggests extrinsic origin, vegetable material. The literature is reviewed and histologic features are illustrated.
Noonan syndrome is characterized by short stature, unusual facies, congenital heart disease, chest deformity, mild mental retardation, and cryptorchidism in males. It may be sporadic or inherited as an autosomal dominant trait and occurs between 1 in 1000 and 1 in 2500 live births. Cherubism is a giant cell lesion of the jaws thought to be transmitted as an(More)
Cancer therapies--including surgery, radiation, and chemotherapy--may unfavorably affect the oral/dental health of patients. Existing dental problems can also result in serious complications that may be prevented by dental intervention prior to cancer therapy. This paper will be limited to a discussion of the detrimental effects of radiation therapy on the(More)
