Postirradiation sarcoma (malignant fibrous histiocytoma) following cervix cancer

A case of postirradiation sarcoma is described. The tumor, a malignant fibrous histiocytoma, occurred in the radiation field 11 years following postoperative external beam radiation therapy (7000 rad) for carcinoma of the cervix. Reports of postirradiation malignant fibrous histiocytoma are rare, and the occurrence of this neoplasm following treatment of cervix cancer has not previously been described. The literature concerning postirradiation bone and soft tissue sarcomas is briefly reviewed, with special attention to malignant fibrous histiocytomas.     

Postirradiation sarcoma (malignant fibrous histiocytoma) of axilla.

A case is reported of a patient who developed a histologically unusual sarcoma in the axilla and chest wall 8 years after receiving radiation therapy (6500 rad) for carcinoma of the breast. This sarcoma showed light- and electron-microscopic features of a malignant fibrous histiocytoma, a tumor not documented among 24 previously reported cases of postirradiation sarcoma following the diagnosis of breast carcinoma. In addition, the literature is reviewed and discussed regarding postirradiation sarcoma in general following breast carcinoma.     

Pleomorphic liposarcoma of a young woman following radiotherapy for epithelioid sarcoma

A case of a metachronous epithelioid sarcoma and pleomorphic liposarcoma in a young woman is described. The first tumor was an epithelioid sarcoma (ES) with focal rhabdoid features localised in the left calf while the second lesion developed seven years later in the same region was diagnosed as pleomorphic liposarcoma resembling myxofibrosarcoma ( myxoid variant of malignant fibrous histiocytoma ) predominantly composed of moderately differentiated spindle cells. Multiple foci of uni- and plurivacuolated lipoblasts were seen. Following the resection of ES the patient received 57 Gy radiation to the region, therefore we regarded the second tumor as a radiation induced liposarcoma. A further interesting feature of this case is that the development of pleomorphic liposarcoma preceded by 6 months the solitary right parabronchial metastasis of ES and after 4 months of metastasectomy a third tumor developed at the site of the first lesion. This tumor showed dedifferentiation toward pleomorphic malignant fibrous histiocytoma. Our case represents a unique case of postirradiation liposarcoma developed on the base of ES.     

Histiocitoma fibroso maligno de pared abdominal

Malignant fibrous histiocytoma is a type of soft tissue sarcoma. Although is usually described as a primary neoplasm it has also been related to previous radiation therapy. We report the case of a 49-year-old woman with a history of chemo-radiotherapy five years before due to a cervix cancer. Five years after, a malignant fibrous histiocytoma was discovered in tattoo radiation fields. A wide resection of the tumor was performed and the abdominal wall defect was covered. Diagnosis of this type of tumors remain controversial, they are very aggressive and surgery is still the treatment of choice.

     

脑部恶性纤维组织细胞瘤1例报道

Malignant fibrous histiocytoma (MFH) firstly described as "malignant fibrous xanthoma" by O'Brien and Stout in 1964, is the most common soft tissue sarcoma of late adult life. Uncertain histogenesis and numerous subtypes make MFH a rather controversial entity. MFH only rare arises from structures of the head and neck. When it does, it most often originates in facial structures, particularly the maxilla. This report details a case of a patient with malignant fibrous histiocytoma presenting clinically as a right-sided large indurated frontoparietal mass, three months after head trauma and eight years after radiation therapy for brain lymphoma located in the right frontal and parietal lobes. Radical excision was a surgical challenge because of the extensiveness of the lesion.     

Malignant fibrous histiocytoma developing in bone 44 years after shrapnel trauma

Tumors induced by foreign bodies are uncommon in humans, but they are a relatively common occurrence in some experimental animals. The development of sarcoma in association with metallic foreign bodies has rarely been reported. The development of a malignant fibrous histiocytoma in a 65-year-old man 44 years after shrapnel fragments lodged in his left arm is described. The literature regarding metallic foreign body-induced cancer in humans is reviewed.     

Postirradiation malignant fibrous histiocytoma

Three patients who were treated successfully with postoperative external radiation therapy for ovarian carcinoma, endometrial adenocarcinoma and bilateral retinoblastoma respectively developed years later malignant fibrous histiocytoma (MFH) within the irradiated field. MFH is a recently described soft tissue sarcoma known for its dual fibroblastic and histiocytic differentiation resulting in a pleomorphic histologic appearance.     

Postirradiation sarcoma. Analysis of a nationwide cancer registry material

Thirty-three cases of postirradiation sarcoma (PIS) from the files of the Finnish Cancer Registry were analyzed. The most frequent first primary tumors were cancers of the breast (seven cases) and female reproductive organs (13 cases). Five patients had a childhood cancer. The median total radiation dose at the site of the PIS was 3600 cGy (1600 cGy to 11200 cGy). The median interval from start of radiation therapy to detection of PIS was 13.2 years (3.4 to 22.8 years). The PIS was of soft tissue origin in 25 of 33 cases. The most frequent histologic types were osteosarcoma (ten cases, including four extraskeletal tumors), malignant fibrous histiocytoma (ten cases), and fibrosarcoma (six cases). The overall crude 5-year survival rate was 29% (calculated from the start of treatment for PIS), and for patients initially treated with either radical surgery or combined marginal surgery and postoperative irradiation it was 67%. The authors conclude that there is a chance for cure for radically treated patients with postirradiation sarcoma that emphasizes the importance of regular long-term follow-up of cancer patients.     

The rapid onset of cutaneous angiosarcoma after radiotherapy for breast carcinoma

Malignant neoplasms known to develop following external beam radiation include squamous cell carcinoma, osteosarcoma, chondrosarcoma, malignant fibrous histiocytoma, mixed mullerian tumors, malignant schwannoma, myelogenous leukemia and angiosarcoma. Latency periods of many years characterize the onset of these tumors following the exposure. Cutaneous angiosarcoma following radiotherapy for breast carcinoma has been rarely documented, occurring up to 13 years postirradiation. Two cases of this entity are reported occurring 37 months postradiotherapy at the site of mastectomy performed for mammary duct carcinoma.     

Treatment of malignant fibrous histiocytoma of the heart.

Primary soft tissue sarcoma of the heart is encountered infrequently in clinical practice. Treatment is reported of an intracardiac malignant fibrous histiocytoma, consisting of maximal surgical resection followed by 5600 cGy of conventionally fractionated radiation therapy. Transesophageal echocardiograms done during follow-up were useful in assessing tumor control. Aspects of patient care are discussed in conjunction with a review of the available literature.     

Lymphocytosis in a patient with malignant fibrous histiocytoma

Malignant fibrous histiocytoma is an uncommon soft-tissue sarcoma. Patients with malignant fibrous histiocytoma may present with unusual clinical findings and an apparent association with malignant hematopoietic disease has been reported. We describe a patient in whom a diagnosis of chronic lymphocytic leukemia was made simultaneously with discovery of a large, retroperitoneal malignant fibrous histiocytoma. Following surgical debulking of the tumor, the patient's blood and bone marrow findings returned to normal.     

Malignant fibrous histiocytoma in bone infarct. Association with sickle cell trait and alcohol abuse

A 42-year-old black man with sickle cell trait and a history of alcohol abuse had a malignant fibrous histiocytoma of the distal femur. The tumor developed in a bone infarct that had been present for at least 54 months. This is the first reported association of malignant fibrous histiocytoma and bone infarct in which the infarct was related to sickle cell trait and alcohol abuse. A detailed map of the sections from the resected femur disclosed a spectrum of cytologic changes in the sarcoma that ranged from bland fibroblasts in the center of the tumor to high-grade sarcoma at the periphery. Awareness of this spectrum has diagnostic importance regarding the potential underdiagnosis of well-differentiated malignant fibrous histiocytoma.     

Early radiation-induced laryngeal malignant fibrous histiocytoma (MFH)

Postradiation sarcoma is a potential late sequela of ionising radiation and its frequency is rare. We present the case of a man with a radiation-induced malignant fibrous histiocytoma with a latent period of 20 months.     

Malignant fibrous histiocytoma in the craniocervical junction presenting with severe occipitalgia

We report a patient who complained of severe occipitalgia caused by destruction of the atlantooccipital joint by tumor invasion. Her symptoms were relieved by tumor resection and occipitocervical fixation. Histological examination of the resected tumor revealed that the tumor cells had an irregular arrangement, remarkable atypia, and pleomorphism with multinucleated bizarre giant cells. The tumor demonstrated no definitive sarcoma differentiation and was identified as malignant fibrous histiocytoma. After tumor resection, the patient received adjuvant radiation and chemotherapy. The tumor regrew outside the radiation field. Chemotherapy with ifosfamide, cisplatin, and etoposide caused remarkable tumor reduction, but suspension of chemotherapy resulted in tumor recurrence. The results of our drug protocol suggest that this regimen is feasible as postoperative adjuvant chemotherapy for malignant fibrous histiocytoma. The role of adjuvant chemotherapy and radiation therapy for this highly malignant rare tumor should be evaluated in a prospective study with precise histological diagnosis.

Adult paratesticular malignant fibrous histiocytoma treated with surgery, systemic chemotherapy and postoperative adjuvant radiotherapy

Paratesticular malignant fibrous histiocytoma is an extremely rare malignancy of the scrotum. This malignancy has rarely been described in the literature and scant information exists on the optimal management of this cancer. We present here a case of a 57-year-old man with a diagnosis of high-grade malignant fibrous histiocytoma of the left intrascrotal region who underwent radical orchiectomy, systemic chemotherapy and postoperative radiotherapy.     

Post radiation sarcoma (malignant fibrous histiocytoma) of the cervical spine following ependymoma (a case report)

A case is reported of a 36 y/o man treated with radiation therapy for cervical cord ependymoma who developed malignant fibrous histiocytoma of the cervical spine 15 years later. Pathology revealed the sarcoma adjacent to the recurrent ependymoma. Post-radiation sarcomas following treatment of central nervous system malignancies is discussed.     

Regional chemotherapy with the use of cisplatin and doxorubicin as primary treatment for advanced sarcomas in shoulder, pelvis, and thigh

Eight patients who had large sarcomas in the hip, thigh, or shoulder girdle have been described. Three had osteogenic sarcomas, and one each had Ewing's sarcoma, biphasic synovial sarcoma, pleomorphic liposarcoma, undifferentiated spindling sarcoma, and malignant fibrous histiocytoma. All eight tumors showed evidence of regression after intraarterial infusion of cisplatin and Adriamycin (doxorubicin) given over 48 hours at 3-week intervals, for a total of between three and seven courses. Tru-cut needle biopsy specimens of five of the lesions were normal after chemotherapy. However, after resection of the regressed fibrotic tumor in seven of the patients, four contained foci of probably viable malignant cells. These cell foci were intraosseous in three cases and in the wall of a cyst in one case. In the remaining case, tumor in the distribution of the infused artery regressed, but tumor in a region supplied by an artery that was not infused continued to enlarge. In one patient with osteogenic sarcoma in the pelvis, despite a good response to intraarterial chemotherapy that was followed by surgical resection and radiotherapy, tumor recurred in an adjacent area in tissues supplied by an artery not infused. A hindquarter amputation subsequently was required. With the exception of the two cases in which adequate tumor arterial infusion was not achieved, local primary tumor control was accomplished by intraarterial infusion chemotherapy followed by local resection or radiotherapy and local resection in all patients. Four patients are well without evidence of residual or metastatic sarcoma 3.5 years after presentation in the case of an osteogenic sarcoma of shoulder, 2.5 years after presentation in the case of a large pleomorphic liposarcoma of thigh and groin, 20 months after presentation in the case of lower-thigh malignant fibrous histiocytoma, and 1 year after presentation in a child with an osteogenic sarcoma of lower femur.     

Malignant fibrous histiocytoma and pleomorphic sarcoma in association with medullary bone infarcts.

A malignant fibrous histiocytoma arose in the proimal tibia of a 40-year-old man who had multiple, symmetrically distributed, medullary bone infarcts of unknown etiology, involving the distal femora and the tibiae. Despite amputation and chemotherapy, widespread metastases developed and death occurred 19 months after surgery. A polemorphic sarcoma, probably representing an anaplastic malignant fibrous histiocytoma, arose in association with a single medullary infarct in the proximal humerus of a 33-year-old woman. She remains well without evidence of disease five years after treatment by radical radiotherapy followed by shoulder disarticulation. Sarcoma arising in association with bone infarction is a rare entity. Sixteen cases reported in the medical literature, including our own, are reviewed. The sarcomas arose in the tibia in nine cases, the femur in six cases and the humerus in one case. The patients were usually older individuals and 13 of the 16 were male. All but two had multiple bone infarctions. Four of the patients had caisson disease, three had what is probably an hereditary bone dysplasia, one had sickle cell disease and eight had infarcts of unknown etiology. Most patients have had a rapidly fatal outcome. Thirteen of the sarcomas have been fibrosarcomas or malignant fibrous histiocytomas, both of which are rare primary bone tumors. Analysis of the published cases of bone infarction-related sarcomas suggests that the risk of developing a sarcoma is greatest in infarcts with large medullary components.
