Diffuse pulmonary infiltrates in hypogammaglobulinemia

: This is the first case report of lymphangitic carcinomatosis from adenocarcinoma of the stomach presenting as interstitial lung disease in a patient with CVH. Adenocarcinoma of the stomach occurs with increased frequency and at an earlier age in CVH as compared with the normal population. This diagnosis should be kept in mind during evaluation of patients with CVH. Periodic examinations of stool for occult blood should be performed. Aggressive diagnostic evaluation should be undertaken in any CVH patient with gastric complaints, as well as careful follow-up in patients with pernicious anemia, atrophic gastritis, or achlorhydria with regard to cancer screening.
