Bruton agammaglobulinemia

no tonsilar tissue is a huge clue here. total lack of Ig which causes recurrent infections after 6mo (maternal IgG is gone). LN and tonsils are minor/non-existent. (FA 2017).

angelaq11  I totally hated this Q! I almost completely overlooked the "no tonsillar tissue", and thank God I didn't because that's the clue that made me change my answer. I had CGD (yeah, I know, S. pneumoniae not catalase +), but it said that he had muuultiple infections since birth. And I took to heart that "since birth" thing, because, isn't Bruton supposed to present with infections from around 6moa? I hope I don't screw this up next week +
