BACKGROUND
Pulmonary vessel sarcomas are rare, and their pathogenesis is still unclear.
METHODS
We focus on the pathologic findings of fourteen pulmonary artery and/or vein sarcomas along with clinical prognosis.
RESULTS
Nine patients were male and five were female, and they ranged in age from 26 to 72 years (mean, 47 years). There were ten cases of pulmonary artery sarcoma, three cases of pulmonary artery and vein sarcoma, and one case of pure pulmonary vein sarcoma. Ten out of the fourteen cases were associated with pulmonary thromboembolism. Microscopically, all the tumors showed an undifferentiated sarcomatous portion. There were leiomyosarcoma portions in 8 cases, malignant fibrous histiocytomatous portions in 7 cases, angiosarcomatous differentiation in 3 cases, and osteosarcomatous portion in 1 case. All but two patients died during the follow up period (range, 1 to 78 months). The mean survival time of the patients who died was 14 months and the longest survival time was 78 months after surgical resection.
CONCLUSIONS
The current study is one of the largest single institutional reviews of pulmonary artery and/or vein sarcoma. Regardless of the histological components and macroscopic growth patterns, these rare tumors have a grave prognosis.

Abstract PDF: Localized enterocolic lymphocytic phlebitis is characterized by selective phlebitis involving the small to medium-sized veins and venules, infiltration exclusively by lymphocytes, and no other systemic vasculitis or inflammatory bowel disease. This vasculitis can be a rare cause of intestinal ischemia. We experienced a case of enterocolic lymphocytic phlebitis in a 72-year-old woman, who presented with abdominal pain and distension. The resected colon and terminal ileum showed striking lymphocytic phlebitis affecting the veins and venules of the bowel and mesentery which resulted in ischemic injury of the bowel. This vasculopathy was the only demonstrable cause of ischemia. Arteritis and arteriolitis was not found. There is no clinical or laboratory evidence or a history of extraintestinal vasculitis. The etiology of this clinicopathological entity has not been elucidated. Herein, we report the clinicopathological findings in this patient who presented with ischemic intestinal necrosis caused by localized intestinal lymphocytic phlebitis associated with thrombosis.
