Anthracosis is the blackish pigmentation of lung parenchyma and tracheobronchial tree. A female Lion Tailed Macaque aged 19 years was being kept captive in Thiruvananthapuram Zoo for 17 years. On 30th November 2019, animal found dead zoo subjected to a necropsy at hospital. The revealed diffused black deposits throughout lungs on gross examination. histopathological analysis, could be as free p...

Background: Tracheobronchial schwannomas are extremely rare tumors of neurogenic origin. Treatment includes surgery and interventional bronchoscopic therapy. Studies that have described therapy for tracheobronchial schwannoma been reported in the published literature, but most them individual case reports, which long-term efficacy recurrence poorly understood. This study aimed to explore feasib...

Bronchogenic cysts that formed during the development of the tracheobronchial tree in the gestational period are mostly asymptomatic until adulthood. Cysts localized in the middle mediastinum, specifically in the subcarinal region, on the other hand, may cause serious symptoms by compressing the heart and major vessels due to their close proximity. In this report it is suggested that surgical r...

Bronchogenic cysts arise from abnormal budding of the ventral diverticulum of the foregut or tracheobronchial tree during embryogenesis, are the most common cystic masses in the mediastinum, and are generally asymptomatic. A spontaneous regression in a mediastinal bronchogenic cyst (MBC) with pneumonia is rare. A 30-year-old male had a tumor shadow in the middle mediastinum. When he visited our...

BACKGROUND Neurogenic tumors of the tracheobronchial tree are extremely rare and include neurofibroma and schwannoma. We report a case of primary recurrent tracheal schwannoma causing obstructive airway symptoms. CASE PRESENTATION A 60-year-old man presented with obstructive airway symptoms due to recurrent tracheal schwannoma. Due the recurrence, size of the tumor and low surgical risk, the ...

Pulmonary sequestration is a congenital abnormality consisting of a mass of pulmonary tissue that presents an abnormal connection with the tracheobronchial tree, with a blood supply coming from an anomalous artery derived from the systemic circulation. Extralobar pulmonary sequestration is characterized by having pleural coverings that are independent of the normal lungs, with vascular supply u...

Pulmonary sequestration is a focal area of nonfunctioning, dysplastic lung parenchyma that lacks communication with the normal tracheobronchial tree. It is supplied by the systemic arterial circulation and has two types, intralobar and extralobar, that can be differentiated from each other by the pleural covering and the venous drainage. Their coexistence is extremely rare. We report the imagin...

Bronchogenic cysts are benign congenital malformations derived from the tracheobronchial tree that correspond to non-functioning lung tissue.1,2 The majority of cases are diagnosed in the pediatric population.3 In adults they are fundamentally found in mediastinum and lung parenchyma.3 However, they can sometimes be located in the thoracic wall, abdomen or cervical region4; in the cervical area...
