Small forms and hyphae of paracoccidioides brasiliensis in human tissue.
A 53 year-old man had a three-year recurrent respiratory infection. No fungi was detected in sputum examinations. Immunodiffusion test with paracoccidiodin revealed two precipitin bands. Very small forms and hyphae of a fungus were seen on silver methenamine stained serial sections from lung's lesion. P. brasiliensis was identified on the basis of the rare multibudding small forms.
