title: [Pathology and clinical aspects of peripheral neuroectodermal tumors].
abstract: A 36-year-old man developed progressive pain in the left thorax radiating to the shoulder, associated with weight loss as well as axillary and supraclavicular lymph-node swellings, and a left Horner's syndrome. The radiological diagnosis was Pancoast tumour. Computed tomography of the thorax revealed that the tumour had almost completely infiltrated the left lung and hilus. Sonography demonstrated metastases in the liver and retroperitoneum. Histological examination of an excised axillary lymph-node metastasis showed an undifferentiated small-cell tumour. Immunohistochemical tests revealed expression of protein S 100 and neurofilamental proteins, i.e. evidence of a peripheral malignant neuroectodermal tumour. The tumour also expressed vimentin. Treatment consisted of two chemotherapy cycles according to the EVAIA scheme (daily three times 235 mg etoposide, 2 mg vincristine, three times 0.8 mg actinomycin D, three times 3.2 g ifosfamide, three times 30 mg doxorubicin, and three times 12 mg dexamethasone), without any effect on the rapid progression of the disease. He died 17 weeks after the diagnosis had been made.
