Endobronchial metastasis of urinary bladder carcinoma

Abstract

Introduction: Bladder cancer is the 12th most common cancer type worldwide. The most common symptom is painless hematuria. The most common sites of distant metastasis are liver (47%), lung (45%) and bone (32%), respectively. Case report: 73-year-old male patient was admitted with the complaint of hematuria. With a preliminary diagnosis of bladder cancer transurethral resection of tumour (TUR-B) was performed and pathology reported invasive urothelial carcinoma. The patient applied to the pulmonary diseases outpatient clinic with the complaint of cough and wheezing. Bronchoscopy was performed with a pre-diagnosis of bladder cancer metastasis. Multiple biopsies from EBL reported in accordance with urothelial carcinoma metastasis. Result: Urothelial carcinoma of the bladder may present with different pulmonary involvement. Although endobronchial metastasis is a rare condition; it should always be kept in mind in patients with respiratory system complaints. Keywords: endobronchial metastasis; bladder carcinoma; urothelial carcinoma; pulmonary involvement.
