ELEVATED SERUM CA19-9 LEVEL AND REGIONAL LYMPHADENOPATHY IN A YOUNG MAN WITH ALLERGIC BRONCHOPULMONARY ASPERGILLOSIS

A 21-year-old man with bronchial asthma who suffered from productive c ough; his chest X-rays and computed tomographic (CT) scans revealed ce ntral atelectasis and pulmonary infiltrates with paratracheal and hila r lymphadenopathy. The serum CA19-9 level was elevated. He was suspect ed to have malignant neoplasms on admission, but he was diagnosed with allergic bronchopulmonary aspergillosis (ABPA) by Rosenberg's criteri a. After steroid therapy, his symptoms and radiographic findings impro ved and the serum CA19-9 level decreased. ABPA should be considered in the differential diagnosis of asthmatic patients with or without lymp hadenopathy and an elevated serum CA19-9 level.
