A Rare Presentation of Teratocarcinosarcoma as a Carinal Mass With Review of Literature.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Teratocarcinosarcoma (TCS) is a rare, highly aggressive malignant neoplasm composed of epithelial, mesenchymal and neuroectodermal elements, occurring almost exclusively in the sinonasal region. Primary involvement of the tracheobronchial tree or carina has not been previously reported. We describe a 55-year-old male chronic smoker who presented with cough, progressive dyspnea and haemoptysis. Computed tomography revealed a lobulated soft-tissue mass in the distal trachea overhanging the carina, extending into both main bronchi, causing significant airway obstruction. Bronchoscopy demonstrated greater than 80% bilateral luminal occlusion, necessitating urgent endobronchial debulking using rigid bronchoscopy, snare electrocautery, and cryotherapy. Histopathology with immunohistochemistry confirmed teratocarcinosarcoma. Positron emission tomography-computed tomography (PET-CT) showed metabolically active mediastinal and hilar lymph nodes. The patient was treated with chemoradiotherapy. Follow-up bronchoscopy at 6 months showed no recurrence, and the patient remains asymptomatic under surveillance for 4 years. This case represents the first reported carinal presentation of teratocarcinosarcoma, expands the anatomical spectrum of TCS and emphasizes the value of multimodality treatment for sustained disease control.
