Hemangiosarcoma of the palm of the hand, also known as malignant angioendothelioma of the palm of the hand, has clear ultrasonographic manifestations, such as the presence of a strongly echogenic nodule or a hypoechoic nodule. In the case of hemangiosarcoma of the palm, ultrasonography reveals a strongly echogenic or hypoechoic mass with blurred borders, irregular morphology, blood flow signals, and potentially heterogeneous internal echogenicity. In addition, cytologic examination can also be used to identify whether the tumor is a hemangiosarcoma. Cytological examination reveals that the tumor cells have atypical endothelial cells, while the cytoplasm of the tumor is rich in microfilamentous vesicles and possibly endoplasmic reticulum-like vesicles. If you are worried about hemangiosarcoma in the palm of the hand, it is recommended to consult a doctor in time, improve the examination, and follow the doctor’s instructions after the diagnosis is clear, and give relative treatment in time.
