This is the first part of a two-part case.
A 70 year old man presents with left lower quadrant abdominal pain of several days. He's had this in the past but previous episodes were mild and he's always ignored the symptoms. This time, though, he also has nausea, vomiting, and constipation. The patient has left lower quadrant tenderness with a palpable mass and abdominal distention. He has a mild fever and leukocytosis. LFTs and amylase are normal.
Challenge: This patient is not Asian. If he were Asian, how might the symptoms differ?
