Severe combined immunodeficiency disease with adenosine deaminase deficiency

Severe combined immunodeficiency disease with adenosine deaminase deficiency was reported of a 1-year-2-month-old boy, who showed clinical picture of pulmonary candidiasis. The serum immunoglobulin level and absolute lymphocyte count were markedly diminished. But immunological study revealed both T- and B-cell surface markers on the peripheral lymphocytes, in spite of complete deficiency of both systems.
