Epithelioid sarcoma is a rare soft tissue tumour, which was first described in 1970. The tumour occurs mostly in young adults and is characterized by multiple recurrences and late metastases. Two patients with epithelioid sarcoma are presented. Clinical and histological features and treatment are discussed. 相似文献

Epithelioid sarcoma is an uncommon soft tissue malignancy which is often misdiagnosed as necrobiotic granuloma or chronic inflammation. Many patients have local recurrence and distant metastasis because of its infiltrating growth. We report a 49-year-old Japanese man who had an ulcer with surrounding erythema on the left forearm after he sustained a bruise on this spot. His mother and father had died of rectal and bladder carcinoma, respectively, and he had also had a seminoma previously. Therefore, there was familial accumulation of malignancies. A skin biopsy revealed polygonal, plump, or spindle-shaped epithelioid cells and lymphocytes infiltrating through the dermis. Immunohistochemical studies showed positive staining for cytokeratins, epithelial membrane antigen, CD34 and vimentin and negative staining for desmin, CD68, HHF-35, 1A4 and p53. These clinical and histological features were diagnostic of epithelioid sarcoma. CT scans detected nodules in the right lung. A lung biopsy revealed that he had well-differentiated adenocarcinoma which expressed p53. Mutations in the TP53 gene were not searched for. We selected conservative treatment because the patient did not want surgical wide resection or amputation. Therefore, radiation, thermotherapy, application of 0.5% doxorubicin hydrochloride ointment and right lower lobectomy with lymph node dissection were performed. The size of the ulcer and the tumor invasion along the fasciae of muscles were decreased, however, metastasis of the epithelioid sarcoma was detected in the lymph node of the left axilla four years after the diagnosis. 相似文献

Epithelioid sarcoma is an uncommon slow-growing soft tissue malignancy, associated with a high incidence of local recurrence and metastasis. We report a 26-year-old male with epithelioid sarcoma on the right palm with a long history of over seven years, which was initially misdiagnosed as cutaneous tuberculosis and epithelioid hemangioendothelioma, as a result of which the treatment was delayed. No metastasis was found in our patient. The patient was referred to the oncology centre where he underwent wide excision of the lesion followed by radiotherapy. The review of the literature including clinical and histological differential diagnosis is presented as it mimics inflammatory, benign tumors as well as other malignant conditions. 相似文献

Twelve cases of epithelioid sarcoma have been reviewed, illustrating the diagnostic problems for which this rare tumor has become notorious and demonstrating varied rates of tumor progression. The histological features most helpful to the distinction of epithelioid sarcoma from other nodular skin lesions, including benign conditions such as rheumatoid nodule and granuloma annulare, are discussed. The ultrastructural appearances of two cases were similar to immature mesenchymal tissue. 相似文献

Epithelioid sarcoma (ES) typically arises as a firm nodule on the extremities of young men. The tumor is remarkable for diagnostic difficulties both clinically and histopathologically resulting in a high frequency of initial misdiagnosis. ES is also known to have a high rate of recurrence and high rate of metastasis predominantly to the lymph nodes, lungs, and scalp. Herein, the second case of ES with metastasis to the tongue is reported. 相似文献

Epithelioid sarcoma (ES) is a rare soft tissue neoplasm that usually occurs on the upper extremity of adolescents and young adults. It rarely occurs during childhood. ES is a slowly growing tumor with a high propensity for recurrences and metastases. This neoplasm is likely to be confused with a variety of benign and malignant conditions. Recognition of ES is important. The treatment consists of wide excision. Misdiagnosis can lead to inappropriate treatment and local recurrences or metastases. We report the case of a 5-year-old girl with an ES on the right forefinger. 相似文献

Epithelioid sarcoma (ES) occasionally may be confused, both clinically and histologically, with isolated necrobiotic granulomas (ING), leading to misdiagnosis and potential mismanagement of these conditions. We studied 11 cases of ES and 11 of ING (6 examples of deep granuloma annulare and 5 of rheumatoid nodule) immunohistochemically, in an attempt to determine whether they could be diagnostically separated by such means. Monoclonal antibodies to cytokeratin polypeptides (CK), epithelial membrane antigen (EMA), and leukocyte common antigen (LCA) were applied to formalin-fixed, paraffin-embedded sections in each case, using the avidin-biotin-peroxidase complex technique. All ES cases stained positively for CK, and 6 expressed EMA, while examples of ING were non-reactive for these antigens. Conversely, the large epithelioid histiocytic cells in cases of ING were immunoreactive with anti-LCA, whereas no case of ES displayed this determinant in tumor cells. In the latter lesions, reactive peritumoral inflammatory cells were LCA-positive, but were readily distinguished from neoplastic cells on morphological grounds, as well as by their negativity with anti-CK and anti-EMA. Based on these data, it is concluded that immunohistologic stains for epithelial and hematopoietic antigens are valuable in the conclusive diagnostic separation of epithelioid sarcoma and necrobiotic granulomas. 相似文献

Development of a malignant tumor is a well known complication of a chronic burn scar. Most of these tumors are squamous cell carcinomas and only 28 cases of burn scar sarcomas have been reported in literature. We report the first occurrence of the combination of squamous cell carcinoma and epithelioid sarcoma arising in a burn scar. 相似文献

A 63-year-old man had epithelioid sarcoma. Light microscopy showed the tumor to resemble granuloma annulare. Enzymatic histocytochemical and ultrastructural studies demonstrated the tumor's histiocytic features. Literature review of epithelioid sarcoma and granuloma annulare showed them to have a similar anatomic distribution. 相似文献
