RESUMO
Extranodal non-Hodgkin's lymphoma (NHL) afflicting the head and neck region is rare, accounting for only about 5%. Diffuse large B-cell lymphoma (DLBCL) is the most common type of NHL affecting the oral cavity. Due to its variable clinical presentation and non-pathognomic course, it can be easily misdiagnosed with overlapping characteristics to common oral pathologies. In the present case, the authors report an unusual presentation of DLBCL and highlight the significant diagnostic challenge encountered by the clinician. In our case, osteonecrosis of the maxilla with soft tissue swelling misleads the diagnosis of chronic osteomyelitis. However, further, work-up was pursued, and the patient was managed successfully with chemotherapy and is currently disease-free for the past 1 year. An accurate clinico-radiological diagnosis with histopathological confirmation is emphasized to deliver a potentially curative treatment in a timely manner.
RESUMO
Dengue infection accompanied by unusual complications and manifestations has been described before. Here we report a case of dengue encephalitis who was IgM positive for dengue serology and had presented to us with only motor weakness after an acute febrile episode. Dengue presenting as encephalitis is in itself a very rare feature and that too, pure motor weakness has hardly ever been reported before.
