Endobronchial Hodgkin's Disease and Bronchoesophageal Fistula Gilda Renzi, M.D., F.G.G.P.,o and, Robert Lesage, M.D. oO
A patient with Hodgkin's disease compUcated in the terminal stage by endobronchial involvement and bronchoesophageal fistula is reported. The patient died of recurrent bronchopneumonia secondary to the fistula. Even though mechloretbamine (Mustargen) intravenously and radiotherapy locally were given, no improvement was noted.
I
n the chest, malignant lymphoma may involve lymph nodes, pulmonary parenchyma and the tracheobronchial tree. Endobronchial involvement is rare and may be diagnosed only by bronchoscopic examination. We present a case of Hodgkin's disease with endobronchial involvement and bronchoesophageal fistula formation. CASE REPORT
A 25-year-old white woman followed and treated for Hodgkin's disease over the past four years was admitted to Notre Dame Hospital with the following symptoms: over the past two weeks she had noted a progressive productive cough. She also noted attacks of fever and dysphagia and dyspnea which were intermittent and secondary to the ingestion of solids or liquids and followed by vomiting and regurgitation. She also complained of generalized pruritus and a significant weight loss. Her past history was noteworthy in that, four years previously, she had a biopsy of a supraclavicular node which revealed Hodgkin's disease. At that time, a chest x-ray film showed marked mediastinal adenopathies and the patient was treated by radiotherapy, 2,000 rads, on the mediastinal region. Following this, she had recurrences in the inguinal region and also the splenic angle of the colon and both these responded to radiotherapy. On her last admission, physical examination revealed a patient who was dyspneic, cyanotic and who presented an almost continuous cough. Blood pressure was 120 over 70 mm Hg, temperature was 101°F, pulse rate was 92 per minute and regular, respiration rate was 30 per minute. Palpable lymph nodes were noted in the cervical area. The trachea was in the midline and the neck veins were not distended. Chest examination revealed no dullness but crepitant rales were heard bilaterally. Examination of the abdomen did not reveal any abnormality. Results of routine laboratory tests were normal. Chest x-ray picture revealed probable aspiration bronchopneumonia but no mediastinal adenopathy. A barium swallow showed a fistula between the left main stem bronchus and the esophagus (Fig 1). Esophagoscopy revealed the fistula to be 26 cm on the anterolateral wall. A biopsy specimen was taken but was negative. During esophagoscopy, as the patient coughed, bubbles of air could be seen in the fistula. Bronchoscopy revealed granular tissue partially obstructing the posterior wall of the left main stem bronchus o Active

LACERATION OF TRICUSPID VALVE
knowledge this case seems to be the first antemortem report of bronchoesophageal fistula formation secondary to bronchial involvement by Hodgkin's disease. A tracheoesophageal fistula was reported by Weber in an autopsy case. Prognosis is related to the degree of bronchial involvement and is comparable to the other malignant causes of bronchoesophageal fistula formation.s-" In the present case, radiation therapy and intravenously administered mustargen were of no avail.

Bronchography revealed an irregular and stenotic left main stem bronchus but no definite fistula was seen. Treatment consisted of absolute diet, antibiotics and 15 mg of mechlorethamine (Mustargen) was given intravenously. Because of no improvement, gastrostomy and radiotherapy, 2,000 rads, on the left main stem bronchus was tried. A repeat barium swallow showed a persisting bronchoesophageal fistula. The patient continued to have repeated bouts of aspiration bronchopneumonia and she finally died of respiratory insufficiency. An autopsy was refused. PATHOLOGY REPORT
• The specimen submitted was taken from the main -Ieft bronchus. The bronchial epithelium was ulcerated and in the same area, there was invasion of the bronchial wall by the neoplastic process which was of a mixed type of Hodgkin's disease. There were lymphocytes and typical reticular cells a few of which were Reed-Sternberg cells. DISCUSSION
Report of antemortem endobronchial involvement with Hodgkin's disease are rare.>" Most cases are diagnosed postmortem.' Endoscopically, there are granular infiltrates of the mucosa in the trachea or bronchi and these may ulcerate. The differential diagnosis is to be made with other inflammatory or neoplastic lesions obstructing the tracheobronchial tree. Definite diagnosis is made by bronchoscopy and biopsy as in this case.
