A case of histiocytosis X (Langerhans type) associated with bullous pulmonary emphysema and acquired immune deficiency, regarding CD4 positive cells, is described. Previous history was remarkable for skin lesions which first appeared in 1981 and progressively worsened, diabetes insipidus diagnosed in 1986, and bullous pulmonary emphysema detected in 1988. Biopsy results of skin lesions were consistent with histiocytosis X. Thyroid gland involvement was found by means of cytological examination. The search for HIV infection (also performed by means of immunoblotting and PCR) was negative. To our knowledge the immunodeficiency detected in histiocytosis X affects the T suppressor lymphocyte subset, so we thought this peculiar case was worth describing.
