Primary Burkitt's Lymphoma in the Nasal Cavity and Paranasal Sinuses

Sinonasal Burkitt Lymphoma in a 2-Year-Old Child: An Uncommon Case Report

Burkitt Lymphoma (BL) is a highly aggressive B-type non-Hodgkin lymphoma. It rarely develops at the level of the sinonasal cavities, especially in young children. We present the case of a 2-year-old boy who presented with a 2-month history of nasal obstruction, snoring, and epistaxis followed by a recent dyspnea. Examination revealed a protruding tissue mass in the left nasal cavity. Computed tomography scan showed a homogenous soft-tissue mass in the left nasal cavity extending toward the ipsilateral orbit, infratemporal fossa, nasopharynx, as well as the ethmoid and maxillary sinuses. Magnetic resonance imaging revealed a homogenous infiltrating mass with a hypo-intense signal on T2-weighted images reaching the infratemporal fossa and oropharynx. Biopsy confirmed the diagnosis of BL. The patient was referred to the clinical hematology department and received complex chemotherapy. Following chemotherapy, imaging revealed significant regression of the mass. We performed a nasopharyngeal biopsy which confirmed the absence of any persistent disease. This case report highlights a rare case of an extensive sinonasal BL emphasizing the importance of a high level of suspicion to ensure an early diagnosis and treatment.

Widely disseminated sporadic Burkitt lymphoma initially presented as oral manifestations in a 6-year-old boy

Burkitt lymphoma, a subtype of non-Hodgkin's lymphoma, is an aggressive neoplasm with three variants that are endemic, sporadic, and immunodeficiency associated. We present an unusual case of sporadic Burkitt lymphoma in a 6-year-old boy who initially presented with hypermobile teeth and no other specific signs or symptoms. On dental radiography, the patient was found to have alveolar bone resorption adjacent to the maxillary first molars, with the appearance of floating teeth. In addition, magnetic resonance imaging (MRI) showed extensive soft tissue masses involving four quadrants of the jaws. A definitive diagnosis of Burkitt lymphoma was made based on tissue and bone marrow biopsy. Subsequent images, including abdominal computed tomography (CT) and bone scan, revealed wide dissemination of the lymphoma into the abdominal cavity, pancreas, and numerous bones. This case suggests the possibility of dental complaints as an initial clinical manifestation of sporadic Burkitt lymphoma and emphasizes the role of dentists in early detection of the disease to improve prognosis.

Sporadic Burkitt Lymphoma Presenting as Acute Pancreatitis, Concurrent Sinusitis, and Enlarged Adenoids

Pancreatitis and sinusitis as presentations of Burkitt lymphoma are uncommon and rarely described in children. We describe here the case of a child who presented with symptoms suggestive of sinusitis unresponsive to antibiotics, with subsequent development of abdominal symptoms due to pancreatitis. He was eventually diagnosed with Burkitt lymphoma.
