Lymphomas of the oral cavity are rare and represent only 3%–5% of all lymphomas. Diffuse large B-cell lymphomas (DLBCLs) are a heterogeneous group of tumor and the most common type of all non-Hodgkin's lymphomas (NHLs). They mostly arise from soft tissue as asymptomatic swelling and involvement of jaw bones is infrequent. We present a case of a 23-year-old patient who developed DLBCL in oral cavity region 4 months after blunt trauma. The patient lacked other physical symptoms at the time of presentation. Histopathology, bone marrow and immunohistochemistry revealed DLBCL. After chemotherapy of eight cycles, swelling was totally reduced and no relapse observed in 10 months’ follow-up period. Thus, the present report represents an example of possible rapport between trauma and unresolved soft-tissue swelling which may be caused by NHLs.
Intraosseous mucoepidermoid carcinoma (IMC) is an atypical salivary gland neoplasm commonly seen in middle-aged adults. Their presentation in young individuals below the age group of 20 years is sporadic. Treatment modality mainly includes radical surgical resection for malignant tumours. There were only 13 reported cases of IMC of mandible below the age of 20 years in the English literature. All the reported cases were only managed with wide resection and radiotherapy. Surgical resection leads to loss of form and function in the young population, decreasing their morale. Hence, reconstruction should be mandated in young individuals for restoring function and aesthetics. We present a case of IMC of the mandible in a young female individual resected and reconstructed with a free fibula bone graft. Satisfactory healing is elicited with no recurrence at the 2-year follow-up period.
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.
