[Differential diagnosis of paragonimiasis in relation to tuberculosis of the lung by transthoracic needle biopsy].

In a citizen of the People's Democratic Republic of Laos who has entered the German Democratic Republic for professional training a lung involvement in the shape of a circular focus was established after pleurisy. Hospitalization followed from suspected tuberculosis. Worm eggs of a lung fluke were parasitologically detected in a transthoracic fine needle biopsy. After administering Biltricide the patient undergoes follow-up treatment as an outpatient. No symptoms have ever occurred since. In a differential diagnosis paragonimiasis in the event of unclear pulmonary infiltrates in citizens from South-East Asia should be taken into consideration in the face of pulmonary tuberculosis, and should be cleared up in an etiological diagnosis, if necessary.
