Tricky Tumors: Atypical Tumors You Don't Want to Miss by Travis Vandergriff MD

• The most common presentation of angiosarcoma is an erythematous or violaceous patch on the scalp or face. UV exposure, lymphedema, and radiation are risk factors. An incisional biopsy or multiple punch biopsies are preferred over shave biopsies.
  
• An atypical vascular lesion of the breast is a vascular neoplasm acquired years after radiation to the breast. They can resemble a lymphangioma or bruise. Excision is recommended for the vascular type, as it can be a precursor to angiosarcoma. Lymphatic type may be monitored.
  
• Diffuse dermal angiomatosis of the breast is a reactive vessel proliferation in the setting of large pendulous breasts. Smoking is a risk factor and a roadblock for improvement.
