Facial asymmetry.

A case of monostotic, mandibular fibrous dysplasia has been described in a 22-year-old Amerasian male, who had facial asymmetry of approximately 5 years' duration. Foci of ill-defined sclerotic, pagetoid calcifications were seen on routine film. The CT scans demonstrated bone facial and slight lingual expansion of bone with thinning of the cortex. A three-dimensional, enhanced CT film showed that this lesion was greater than 4 cm. The clinical, radiologic, and microscopic features of fibrous dysplasia have been described.

Mixed density lesion of the anterior maxilla.

A case of COC which developed as a mixed lucent-opaque lesion in the anterior maxilla of a young person is discussed from the standpoint of clinical and radiographic differential diagnosis. Current concepts of the pathology of the COC and EOGCT are discussed.

White plaque of the dorsal tongue.

A case of oral lichen planus has been discussed. The causes, associated conditions, laboratory tests, and treatment were addressed. The use of cyanoacrylate "super glue" may have acted as a contactant and promoted the patient's localized lichenoid process. No additional treatment was provided other than confirmation of clinical suspicions. The most important factor was ruling out the possibility of a dysplastic or a malignant process. Should the patient become symptomatic, the treatment would probably start out with kaolin and pectin (Kaopectate) lidocaine/benadryl rinses. Should supportive therapy fail, alternative regimens including topical to systemic corticosteroids would be considered.

Exophytic mass of the floor of the mouth.

A tissue mass in the floor of the mouth was found to be an unusual, exophytic squamous cell carcinoma. The patient also had synchronous hepatic metastasis from an occult primary adenocarcinoma. The case is discussed from the standpoint of the differential diagnosis of lesions that may appear as masses of the floor of the mouth. Individuals with one primary cancer are at increased risk for developing second malignancies which may be in either the same anatomic area or in other organ systems. This case report emphasizes the need for the clinician to periodically follow-up any patient with a history of malignancy.

Multiple radiopaque masses in the jaws.

In this report, the less common oral findings occurring in Gardner's syndrome are described, which occurred concurrently with colorectal polyposis. In addition, what clinically appeared as small intestinal polyps, microscopically represented nodular lymphoid hyperplasia, as reported in the literature. Review of the literature showed the oral findings reported here are not common and that enzyme assays can help detect polyps at an early stage of this complex syndrome.

Rapidly expanding pigmented lesion of the buccal mucosa.

A case of oral melanoacanthoma was presented. The differential diagnosis of pigmented lesions of the oral mucous membrane includes a wide variety of categories of disease including local and systemic manifestations of hereditary and developmental conditions, reactive and inflammatory lesions, neoplasms, and metabolic diseases. For some of these lesions the histopathological pattern is diagnostic; for others, the tissue structure and organization are nonspecific and intelligent evaluation requires clinicopathological correlation. This discussion of oral mucosal pigmented lesions emphasizes the importance of the clinical parameters in the differential diagnosis of this group of lesions.
