A case is presented of a patient who developed agranulocytosis with a peripheral monocytosis and a marrow histiocytosis secondary to ampicillin therapy. A brief review of this complex, previously called leukopenic infectious monocytosis, is presented, with emphasis upon the beneficial prognosis of monocytosis. Since this is the first case report of agranulocytosis induced by ampicillin, ampicillin's chemical structure is examined. It is pointed out that ampicillin contains an alpha-aminobenzene, a structure common to many drugs previously implicated in causing agranulocytosis. A brief discussion of the previously postulated causal mechanisms involved in agranulocytosis is presented.
