Background. Patients with allergic bronchopulmonary mycosis can develop cystic changes and fibrosis; thus, an early diagnosis and treatment with corticosteroids and anti-fungal drugs are recommended. Case. A 73-year-old man underwent bronchoscopy because the shadow around the mucus plug of left lower lobe had expanded. The mucus plug found in the left B* (subsuperior bronchus) was removed by bronchoscopic suctioning. Although the causative agent could not be identified, Grocott's staining revealed fragment-like fungal hyphae, and the patient was diagnosed with allergic bronchopulmonary mycosis. He was followed up without medication because his symptoms improved after bronchoscopy. He had no relapse and chest CT showed the disappearance of the mucus plug. Conclusion. Although caution is required to avoid the progression of respiratory failure, in some cases, follow-up is possible without the administration of systemic steroids or anti-fungal drugs after the removal of the mucus plug.
