Angiosarcoma is a malignant endothelial cell tumor that involves a variety of anatomic sites with the skin being the most common. Cutaneous angiosarcoma is a diagnostic challenge as it can be confused with lesions such as rosacea, hemangiomas and hematomas. Since the tumor has a propensity for early metastasis and extensive intradermal spread, early diagnostic intervention via punch biopsy may prevent delays in diagnosis and improve tumor resectability and prognosis. We present a case of cutaneous angiosarcoma on the nose and cheeks of a 75-year-old male that resembled rosacea.

Abstract:
Introduction. Angiosarcomas (AS) arising from vascular tissue, accounting for 3.3% of all sarcomas, have a poor prognosis. Radiation-induced AS is a rare late complication of radiotherapy treatment and is characterized by a gene expression profile such as amplification of the MYC oncogene, by which we can distinguish primary from the secondary induced tumor. Case report, At 77-year-old patient, with early-stage endometrial adenocarcinoma, the radical hysterectomy with bilateral salpingo-oophorectomy was initially done. According to pathological risk factors, the postoperative external beam con

Abstract:
Primary Angiosarcoma of the skin of the foot is very rare. Angiosarcoma is typically treated with resection and wide-field postoperative radiation therapy. Chemotherapy and radiation therapy have also been used. Regardless of the treatment, the risk of local and distant relapse remains high for this disease. We present a case of an elderly patient who developed cutaneous angiosarcoma of the foot. It posed as a diagnostic dilemma at presentation. Chronic lymphedema was a possible predisposing factor. Given his age, preexisting renal dysfunction, refusal of surgery, and preference not to receive

Abstract:
Importance: Radiation-induced angiosarcoma after conservative treatment of breast cancer affects a small percentage of patients but has a significant impact on survival. Early detection requires a high index of suspicion and is important for optimal management of this aggressive disease. Observations: The patient reported here presented with radiation-induced angiosarcoma of the left breast 14 years after radiation therapy. Histopathology was positive for anti-CD31, anti-CD34, D2-40, and anti–factor VIII (von Willebrand). She underwent a total mastectomy and is still in remission 20 months lat

Background Primary cardiac tumors are rare, and many diagnosed tumors are benign with an incidence of 0.001% to 0.03%. The primary angiosarcoma is one of the malignant entities. Discussion We discuss a case report of a 76-year-old male who underwent a preoperative diagnosis for an upcoming shoulder operation when his cardiologist diagnosed a large cardiac tumor. The patient was referred to our department where he received further diagnostics. The transesophageal echocardiography and the cardiac-magnetic resonance imaging showed a massive tumor with a dimension of 8.6 × 5.6 cm with no signs of

Abstract We report the case of a Kaposi-like variant of splenic angiosarcoma in a 28-year-old woman. The tumor featured a Kaposi sarcoma–like spindle cell proliferation with slit formation and markedly dilated spongelike vascular channels filled with erythrocytes. Thirteen months following the initial splenectomy, metastatic lesions were found in the patient's liver and bone marrow. The proliferating cells were positive for factor VIII–associated antigen and CD34. The human herpesvirus 8 genome, which is regarded as a diagnostic feature of Kaposi sarcoma, was not detected by polymerase chain r
