Introduction: The family doctor often sees signs and symptoms of an apparently benign nature that may turn out to be part of more severe disease. This case presents the common finding of facial edema that was interpreted as angioedema, when the underlying disease was the superior vena cava syndrome (SVCS). Case description: A 61-year-old man consulted his family doctor because of an episode of syncope. He was sent to the hospital emergency department, where vasovagal syncope was diagnosed and a microcytic hypochromic anemia was found. Subsequent investigations revealed iron deficiency anemia and a gastric antral ulcer. Three months later, he returned to the Family Health Unit with facial edema and was treated with an antihistamine. Because of persistence of his complaints, he consulted at the hospital emergency department, where angioedema was diagnosed. One month later, he was admitted to the hospital for treatment of gastrointestinal bleeding from the gastric ulcer. He later returned to the hospital emergency department with respiratory symptoms. A chest radiograph revealed enlargement of the superior mediastinum. Following admission to hospital, the diagnosis of a B-cell lymphoma was made after an incisional biopsy of an enlarged cervical lymph node. Comment: This case illustrates the diagnostic challenge presented by lymphoproliferative disorders. Distinguishing between angioedema and superior vena cava syndrome was a central challenge. Cases of diagnostic confusion between these two entities have been described in the literature. Questions related to the complexity of clinical presentations and the difficulties experienced by the family doctor in the management of this case are discussed.
