Simultaneous bilateral spontaneous pneumothorax secondary to metastatic angiosarcoma of the scalp: report of a case.

Angiosarcoma is a highly malignant neoplasm, which most often develops on the scalp or face of elderly people. Common distant metastatic sites include the lung, liver, lymph nodes, and skin. We report a case of angiosarcoma manifesting as simultaneous bilateral spontaneous pneumothorax secondary to pulmonary metastases in an 86-year-old man.

Spontaneous hemothorax caused by intrathoracic synovial sarcoma.

Synovial sarcoma, which is a soft tissue malignancy, primarily affects the extremities in the para-articular regions in adolescents and young adults. Synovial sarcoma of the pleural cavity is extremely uncommon, and there have been only a few reports in the literature. We report here an unusual case of left-sided spontaneous hemothorax as a presenting manifestation of intrathoracic synovial sarcoma in a 33-year-old pregnant woman.

Extrathoracic neurilemoma of the lateral chest wall mimicking a subcutaneous tumor: report of a case.

Neurilemomas of the chest wall are usually solitary lesions which bulge toward the pleural cavity in the posterior mediastinum. We report a rare case of neurilemoma growing outside the thorax from the intercostal nerve. A 33-year-old man was admitted with a chest wall bulging mass.

[A patient with recurrent breast cancer whose liver metastasis regressed following combined use of weekly docetaxel and MPA.5'-DFUR].

A 28-year-old woman who was 10 months pregnant was diagnosed with left breast cancer. She received preoperative chemotherapy and underwent mastectomy after parturition. Endocrine therapy and adjuvant CMF and CAF was administered, but a bone metastasis appeared 2 years later and a liver metastasis 3 years later.

[Analysis for predicting the prognostic factors of gastrointestinal tract leiomyosarcoma using MIB-1 and DNA flow cytometry].

Purpose: The present study was undertaken to investigate the possibility of determining a prognosis for gastrointestinal tract leiomyosarcoma with the use of DNA analysis and MIB-1 staining.

Subjects And Methods: Malignant tumors originating in smooth muscle of the gastrointestinal tract, surgically excised from 23 lesions in 17 patients (stomach; 8 cases, 12 lesions; small intestine: 6 cases, 8 lesions; colon: 3 cases, 3 lesions) and embedded in paraffin, were examined. DNA was analyzed using flow cytometry to produce a DNA histogram, and aneuploidy and diploidy were found.
