Аннотация
BACKGROUND: Solitary papillomas of the lung are rare. One of their subtypes is glandular papilloma with only a very few cases described in the literature. We describe a case of pulmonary glandular papilloma with emphasis in its differential diagnosis and its molecular analysis.
CASE DESCRIPTION: A 64-years old former smoker was incidentally found to have an endobronchial tumor of the right main bronchus. Microscopic and immunohistochemical findings revealed a glandular papilloma. EGFR, KRAS and BRAF V600E mutation analysis, as well as HPV detection analysis revealed no mutation or HPV infection. Detailed differential diagnosis and literature review are presented.
CONCLUSION: Glandular papillomas of the lung are usually central, affecting older patients than squamous or mixed squamous cell and glandular papillomas. In previously reported cases, one glandular papilloma with KRAS mutation and another one with BRAF mutation have been reported. The present case harbored no mutation or HPV infection.
