A 69-year-old alcoholic manwith pneumonia and sepsis due to Aeromonashydrophila is presented. He died of suffocation by a copious amount of hemoptysis six hours after his first symptoms of abdominal pain, diarrhea and dyspnea. Aeromonas hydrophila was isolated from blood and bronchial secretion. A fulminant form of pneumonia could develop in patients with predisposing underlying conditions such as alcoholism with chronic hepatitis and diabetes mellitus. Aeromonas hydrophila pneumonia may be characterized by hemoptysis and rapid clinical deterioration with a high mortality rate. (Internal Medicine 35: 410-412, 1996)

Weencountered a 73-year-old man with acute pulmonary embolism (PE) and Baker's cyst. Venography revealed that the right popliteal vein was compressed by Baker's cyst and deep venous thrombosis (DVT) had developed. DVTassociated with Baker's cyst is rather commonand these two conditions are thought to be causally related. Baker's cyst is the most frequent mass lesion in the popliteal region. Wesuggest that Baker's cyst is a risk factor for PE as well as surgery and trauma. (Internal Medicine 35: 886-889, 1996)
