a case of pulmonary paragonimiasis in Mindanao, Philippines.

A case of pulmonary paragonmiasis was diagnosed in a woman of the Manobo tribe in Marilog, Calinan, in the Davao region of Mindanao, the second-largest island in the Phillippine Archipelago. She had the first case of this disease reported in Mindanao. The patient was initially mis-diagnosed as having pulmonary tuberculosis, but failure of the standard triad regimen led to microscopic identification of Paragonimus westermani eggs in sputum. Therapy with Bithionol was successful in this case. One additional case was confirmed, and several more suspected, among members of this population group. From an epidemiologic standpoint, careful examination of chest x-rays will allow early differentiation between pulmonary paragonimiasis and tuberculosis, in areas where both conditions are endemic.
