Summary
A rare primary pulmonary artery rhabdomyosarcoma was diagnosed in a 69-year-old woman presenting with dyspnea and leg edema. Surgical resection is the recommended treatment for this malignant tumor.
Area of Science:
- Cardiovascular Medicine
- Surgical Oncology
- Pathology
Background:
- Primary pulmonary artery rhabdomyosarcoma is a rare and aggressive malignancy.
- Early diagnosis is often challenging due to non-specific symptoms and potential misdiagnosis as other pulmonary artery obstructive diseases.
Observation:
- A 69-year-old woman presented with dyspnea, right upper quadrant pain, and lower extremity edema.
- Echocardiography revealed a large hypoechoic mass on the pulmonary artery wall causing stenosis.
- CT imaging confirmed an irregular filling defect in the main pulmonary artery.
Findings:
- Histologic and immunohistochemical analysis post-surgical resection confirmed a primary pulmonary artery rhabdomyosarcoma.
- The tumor exhibited irregular borders but clear demarcation from surrounding healthy tissue.
Implications:
- Increased clinical awareness is crucial for timely diagnosis of pulmonary artery rhabdomyosarcomas.
- Surgical resection is the primary therapeutic approach for this rare malignant tumor.
- This case highlights the importance of comprehensive diagnostic evaluation for pulmonary artery masses.

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
01:30Pulmonary Hypertension: Classification and Pathogenesis
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
