American Burkitt's lymphoma manifested in a solitary submandibular lymph node.

An interesting and unusual case of undifferentiated lymphoma, Burkitt's type, solely presenting as a submandibular mass in a 24-year-old white American man has been presented. Although surface marker studies were not undertaken, the morphologic and cytologic aspects of the lesion fulfilled the requirements for a diagnosis of Burkitt's lymphoma. The patient is under chemotherapy and careful follow-up and seems to be clinically free of residual disease.

Congenital granular-cell epulis. Report of a case.

The congenital granular-cell epulis is an uncommon pedunculated tumor of the alveolar mucosa found only in newborn infants. This lesion can present an alarming appearance and interfere with efforts at nursing. The generally accepted treatment is excision through the pedicle, and recurrence is not to be anticipated.

Juvenile fibromatosis with invasion of the mandible: report of two cases.

Two cases of juvenile fibromatosis involving the mandible were found in children aged 1 1/2 and 2 1/2 years. The tumors, while histologically benign, were clinically aggressive, causing bone erosion and destruction and invading adjacent normal soft tissue structures with firm fibrous tumor extensions. In each instance, the lesion was completely removed by radical local surgery with no recurrence after a seven-year follow-up.

Lipsarcoma of the cheek.

A case of liposarcoma of the cheek in a 39-year-old man has been presented. This tumor, which is one of the most common malignant tumors of soft tissues in the body generally, is extremely rare in the oral regions. Initial surgical excision in this case was followed closely by a second more extensive local dissection in view of the pronounced tendency of the liposarcoma to infiltrate locally beyond the apparent limits of ite pseudocapsule.

Nonfatal anaphylaxis caused by oral penicillin: report of case.

Severe allergic reactions may occur after the ingestion of oral penicillin. It is essential that the dentist who prescribes the drug is familiar with the rationale for therapy and is equipped to initiate urgently needed treatment.
