Adult severe combined immunodeficiency and sarcoid‐like granulomas with hypersplenism

Abstract
A patient presented with lymphopenia, anergy, hypogammaglobulinemia and hypersplenism. Histologic examination of the spleen and lymph node revealed noncaseating sarcoid‐like granulomas. Despite a significant rise in circulating lymphocytes after splenectomy there was in vivo and in vitro evidence of B‐ and T‐lymphocyte dysfunction. A histologic picture mimicking sarcoidosis may occur in patients with immune deficiency. The granulomatous proliferation may represent an altered host response to antigen.
