ABSTRACT
A case involving primary lymphoma of the mandible is presented. The difficulties in diagnosis of this particular pathology are highlighted. The features of primary lymphoma of the mandible are described based on a review of the literature. Malignant lymphoma must be considered in the differential diagnosis of unexplained dental pain, swelling, ulceration, and radiographic evidence of rarefaction.

Synovial chondromatosis is an uncommon benign condition in which chondroid bodies are formed within the joint spaces. As calcification of these joint bodies progresses, the radiographic appearance may mimic that seen in other more common pathologic processes including degenerative joint disease. This report describes the clinical and histopathological findings in a case in which 22 "joint mice" were encountered in the joint space of a patient presenting with symptoms of temporomandibular joint dysfunction.

The vacuum effect of a surgical suction tip can induce significant artifactual alterations in the connective tissue of specimens removed for diagnostic or therapeutic purposes. The alterations described in this article consist of a surgical suction artifact characterized by the formation of numerous, pleomorphic vacuoles that, on casual microscopic examination, resemble the morphology of traumatized adipose tissue. This artifact occurs when a vacuum draws air into connective tissue and mobilizes connective tissue mucins (acid mucopolysaccharides) that localize within the vacuoles that are formed.
