Selective immunoglobulin M deficiency in an adult with miliary tuberculosis: A clinically interesting coexistence. A case report and review of the literature

Selective immunoglobulin M (SIgM) deficiency is a rare form of dysgammaglobulinemia. Here we are reporting a 31 year old man with multiple cervical and testicular abscesses who was investigated and found to have miliary tuberculosis (MTB) with primary SIgM deficiency (Serum IgM: 17.4 mg/dL) and was treated aggressively with anti-tuberculous treatment.
