An elderly man with a questionable bronchial carcinoid tumor of long duration and recently increasing tracheal obstruction

Article Abstract:

The diagnostic process of a patient with an amyloidoma in the trachea is described. The patient, an 80-year-old man in good general health, was known to have a growing lung tumor, recurrent episodes of pneumonia, and recent respiratory distress. The tumor was located in the left main bronchus (airway), and had first been found 22 years earlier. The mass had grown to obstruct the left main bronchus and cause total collapse of the left lung. No evidence of metastasis was noted. Calcifications on the edges of the tumor led doctors to rule out malignancy. Granulomatous infections such as tuberculosis were ruled out as a cause of the tumor. An amyloidoma was strongly considered as this kind of tumor is likely to grow in an airway and is not caused by infection. Tracheobronchial amyloidosis, the anatomical diagnosis, grows slowly and may cause recurrent pneumonia. Benign neoplasms such as carcinoid tumor and hamartoma were considered by two of the doctors. The tumor was surgically removed and the patient's health improved.

A preterm newborn female triplet with diffuse cystic changes in the left lung

Article Abstract:

An 18-day-old girl was hospitalized because of X-ray evidence of cysts in her left lung. She had been one of triplets who had been born premature and she had been treated for respiratory distress syndrome. She was hospitalized when she began breathing rapidly. A CT scan revealed that most of her left lung was filled with cysts. Pulmonary interstitial emphysema is relatively common in premature infants treated with artificial ventilation and this was suspected in her case. Surgery revealed progressive destruction of her left lung by cysts and the lung was removed. Microscopic examination of some lung samples confirmed the diagnosis.

Tachypnea, changed mental status, and pancytopenia in an elderly man with treated lymphoma

Article Abstract:

A 74-year-old man with a history of lymphoma was admitted to a hospital because of relapse. He had been treated with chemotherapy and radiation treatment in the past. He had become confused and disoriented prior to his admission. On the fifth hospital day he developed respiratory distress, which did not respond to oxygen supplementation. He gradually became unresponsive and died on the seventh day of hospitalization. At autopsy, lung samples contained fat globules, as did many of his other organs. The lymphoma had invaded his bones, which probably caused the fat embolisms.
