Single-institution, multidisciplinary experience with surgical resection of primary chest wall sarcomas.

Introduction: Primary chest wall sarcomas are rare mesenchymal tumors and their mainstay of therapy is wide surgical resection. We report our single-institution, multidisciplinary experience with full-thickness resection for primary chest wall sarcomas.

Methods: A retrospective review of our prospectively maintained databases revealed that 51 patients were referred for primary chest wall sarcomas from 1990 to 2009.

Chest wall sarcomas are accurately diagnosed by image-guided core needle biopsy.

Objective: Sarcomas are rare mesenchymal malignancies. Accurate preoperative diagnosis is a prerequisite in considering investigational or institutional management algorithms that include neoadjuvant treatment. We reviewed our experience using core needle biopsy for chest wall sarcomas.

Pneumoperitoneum after sexual assault in a patient who had hysterectomy 30 years ago: case report.

Background: A non-surgical etiology accounts for approximately 10% of cases of pneumoperitoneum. However, in the patient with pneumoperitoneum, one must be suspicious of the less common non-surgical etiologies, including coitus, to avoid unnecessary laparotomy.

Objectives: To report a case of pneumoperitoneum caused by coitus during sexual assault in a patient who had a hysterectomy 30 years ago.

PGE(2) contributes to TGF-beta induced T regulatory cell function in human non-small cell lung cancer.

CD4(+)CD25(bright) regulatory T cells (T(reg)) play an important role in cancer-mediated immunosuppression. We and others have previously shown that prostaglandin E2 (PGE(2)) and transforming growth factor beta (TGF-beta) induce CD4(+)CD25(bright)FOXP3(+)T(reg). Based on these studies, we investigated the requirement for PGE(2) in Treg induction by TGF-beta.

Surgical management of endobronchial solitary fibrous tumors.

Solitary fibrous tumors of the pleura are rare neoplasms with both benign and malignant behaviors that are not reliably predicted by histologic findings. We report the case of a 55-year-old woman with recurrent pneumonias whose left mainstem bronchus was occluded by a 2.1- x 1.
