Delayed diagnosis of oral lymphoma: a case series.

Abstract

Lymphomas are the second most common neoplasm in the head and neck. The clinical and radiographic presentation of non-Hodgkin lymphoma in the oral cavity is non-specific and can be hard to differentiate from other common infectious or inflammatory conditions. We report four cases of lymphoma of the head and neck, which presented as odontogenic infection, osteomyelitis, or cutaneous infection, and subsequently led to a delay in provision of appropriate treatment. Correlation between clinical, radiographic and histological findings is essential in reaching an accurate diagnosis. It is important for clinicians to consider malignant lesions, such as lymphoma, in the differential diagnosis of pain, swelling, tooth mobility or radiographic radiolucencies. Clinicians should maintain a high level of suspicion for malignancy when inflammatory lesions fail to respond to normal modes of treatment.
