1/17. Intra-abdominal angiosarcomatosis after radiotherapy.BACKGROUND: We report a case of a 61-year-old Japanese woman who developed intra-abdominal angiosarcomatosis 20 years after receiving radiotherapy for squamous cell carcinoma of the cervix. methods AND RESULTS: The surgically resected portion of the ileum showed diffuse proliferating angiosarcoma, with irregular channels lined by atypical vascular endothelial cells. Immunohistochemical studies showed that the tumour cells were positive for factor viii-related antigen and ulex europaeus agglutinin 1. At autopsy, the tumour had disseminated to the peritoneum and invaded into the right thoracic cavity. CONCLUSIONS: These findings were compatible with radiation-induced angiosarcomatosis.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
2/17. Cutaneous breast angiosarcoma after conserving treatment of breast cancer.Cutaneous angiosarcoma is a rare malignancy that sometimes occurs as a late sequela of breast conservation therapy. We report on a 79-year-old female who developed well-differentiated angiosarcoma in a lymphedematous left breast 5.5 years after surgery and radiotherapy for early invasive ductal breast cancer. The initial appearance was very similar to late radiation dermatitis, and histologically interpreted as scar tissue with atypical vascular lesion. The lesion progressed further, and was clinically suspicious for angiosarcoma. Thus, a second biopsy was taken which confirmed the diagnosis. A complete mastectomy removed all the tumor with clear margins. However, within a period of 16 months she presented four local recurrences which were treated by wide local excision. At present, the patient is free of locally recurrent tumour for 7 months. The few cases of breast angiosarcoma after breast conservation therapy reported so far demonstrate that these lesions are difficult to diagnose due to their rarity and their highly variable and benign appearance, which sometimes may mimic radiation-induced cutaneous changes. Since chronic lymphedema possibly contributes to the development of angiosarcoma, long-term clinical surveillance of these patients is recommended. Biopsies should be taken if new skin lesions occur.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |

4/17. radiation-induced laryngeal angiosarcoma after cervical tuberculosis and squamous cell carcinoma: case report and review of the literature.Primary laryngeal angiosarcoma (LA) is quite rare with only 13 cases reported in English literature to date. A case of LA after radiation therapy for tuberculosis and squamous cell carcinoma is reported. A 70-year-old woman had a history of radiation therapy for left cervical tuberculosis at the age of 28. At 60 years of age a squamous cell carcinoma of the larynx was found and chemotherapy and radiotherapy, consisting of a total dose of 68.4 Gy, were administered. At the age of 68, recurrent squamous cell carcinoma was suspected from several biopsies, and a total laryngectomy with right thyroidectomy was performed. The tumor cells formed vascular spaces and expressed some endothelial markers, such as CD34, CD31, and ulex europaeus agglutinin I, but no epithelial markers, such as cytokeratins or epithelial membrane antigen. No residual squamous cell carcinoma was found. In the present case, it was suspected that irradiation to the larynx for cervical tuberculosis and squamous cell carcinoma induced angiosarcoma. The patient was still alive despite multiple skin and soft tissue metastasis 3 years and 6 months after the radical operation. Distinction of postirradiation angiosarcoma from pseudoangiosarcomatous carcinoma seems difficult but is important because irradiation is not effective and an initial radical surgery is the only effective treatment. Although irradiation is a common treatment for laryngeal squamous cell carcinoma, this is only the second case of radiation-induced LA in English literature.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
5/17. Angiosarcoma of the larynx. Case report and review of the literature.Angiosarcoma of the larynx is a rare malignant tumour of vascular origin, accounting for less than 1% of all malignant tumours of the larynx. Angiosarcoma involves, in particular, the head and neck in areas such as the scalp and face. The causes are unknown, even if, in some cases, it is believed to be radiation-induced. The case is described of a patient with hypopharyngolaryngeal angiosarcoma, which became manifest with dysphagia, dysphonia and a palpable right latero-cervical mass about 7 cm in length. The patient underwent total pharyngolaryngectomy, right hemithyroidectomy, and bilateral neck dissection. Histological examination of the surgical specimen revealed a large haemorrhagic lesion involving the right pyriform sinus and homolateral hemilarynx. Right radical neck dissection revealed 9 metastatic lymph nodes, 1 of which with capsular invasion. Upon complete recovery the patient, underwent adjuvant post-operative radiotherapy. Six months later she is still alive with no clinical or radiological signs of disease. A careful review of the literature produced very few reports of such cases, only 6 of which in the last 30 years. survival rate is very low, even if feasible average can be advanced, in view of the paucity of the case reports. Histological diagnosis is not always straightforward, as this neoplasm may be misdiagnosed as other vascular tumours (Kaposi's sarcoma, haemangiopericytoma), as non-neoplastic lesions (granulomas secondary to intubation) and as poorly differentiated squamous cell carcinoma. Immunohistochemical evaluation by means of markers, such as vimentin and factor viii, offers a significant contribution to the diagnosis of angiosarcoma. The treatment of choice for laryngeal angiosarcoma is surgical excision, ample and radical, whenever possible, followed by adjuvant post-operative radiotherapy.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
6/17. radiation-induced angiosarcoma after mastectomy and TRAM flap breast reconstruction.radiation-induced angiosarcoma of the breast is being reported with increasing frequency as a result of the increased use of radiation therapy in conjunction with breast conservation surgery. However, this entity has not been well documented in patients undergoing mastectomy. The authors present a case of angiosarcoma occurring in a patient 6 years after undergoing mastectomy for invasive duct carcinoma with immediate transverse rectus abdominis musculocutaneous flap reconstruction followed by postoperative radiation therapy. The diagnosis of angiosarcoma was made by skin biopsy performed by the patient's reconstructive surgeon on routine follow-up examination. This is the first reported case of postradiation angiosarcoma occurring in a postmastectomy breast reconstructed with autogenous tissue and it is unusual in that the cancer invaded the musculocutaneous flap. diagnosis and management recommendations for radiation-induced angiosarcoma are discussed.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
7/17. radiation-induced angiosarcoma of the breast shows major response to docetaxel after failure of anthracycline-based chemotherapy.We report on the case of a patient with a diagnosis of an uncommon breast tumour, namely a radiation-induced angiosarcoma, which was primarily refractory to anthracycline-based chemotherapy, but highly sensitive to docetaxel. Although the sarcomas in general tend to be relatively refractory to taxanes, there is some evidence that the angiosarcomas may be sensitive to these agents. This is particularly well documented with paclitaxel, but may also be the case with docetaxel.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
8/17. Irradiation-induced penile angiosarcoma.We report a case of angiosarcoma of the glans penis in a 77 year old male Caucasian. The tumour developed 18 years after a course of radiotherapy for a penile ulcer which was an intra-epidermal squamous carcinoma. The differential diagnosis and the concept of radiotherapy-induced angiosarcomas are discussed.- - - - - - - - - - ranking = 4keywords = radiation-induced (Clic here for more details about this article) |
9/17. Post-irradiation angiosarcoma of the greater omentum.A case of angiosarcoma of the greater omentum is reported. This angiosarcoma developed 8 years after irradiation for cervical carcinoma and presented with an intra-abdominal hemorrhage. We describe her clinical course, treatment and follow-up. Although several other locations of irradiation-induced sarcomas have been published, this is the first report in literature of a postirradiation angiosarcoma in the greater omentum.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
10/17. Postirradiation hemangiosarcoma of the chest wall. Report of a case.An unusual case of cutaneous hemangiosarcoma that developed on a chest wall irradiated after mastectomy for cancer is described. The patient, an elderly woman, had previously received high-dose radiation to the chest wall as well as systemic combination chemotherapy. Sarcoma developed 6 years after mastectomy and progressed rapidly. The time between radiation therapy and occurrence of cutaneous sarcoma was shorter than the median latent period reported for development of radiation-induced sarcoma. Thus, we cannot be certain that radiation was the true or sole etiologic factor. Whether the addition of systemic chemotherapy was a contributory agent is also speculative.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
