Mary is a 13-year old female who presents with a 10-month history of night sweats, fatigue, and weight loss. She presents to urgent care with complaints of flu-like symptoms. Her physical exam is notable for bilateral cervical lymphadenopathy (1-2 cm), mild splenomegaly, and mild edema. She has no neuropathy and no joint pain. She is referred to a hematologist to rule out lymphoma. Her medical history is unremarkable.
