Endometriosis causing extensive intestinal obstruction simulating carcinoma of the sigmoid colon: a case report and review of the literature.

Endometriosis with intestinal serosal involvement is not uncommon in women of childbearing age, however, presentation as colon obstruction is rare. Lack of pathognomonic symptoms makes diagnosis difficult, the main problem being differential diagnosis with neoplasm, even intraoperatively. Reported here is a case of extensive bowel obstruction due to sigmoid colon endometriosis in a 43-year-old woman who presented with signs and symptoms of bowel obstruction. Barium enema showed sigmoid obstruction; subsequent exploratory laparotomy showed the sigmoid colon surrounded by fibrous tissue, leading to its angulation and extensive lumen obstruction. Left oophorectomy and radical resection of descending and sigmoid colon as for bowel carcinoma were successfully employed. Pathological examination revealed endometriosis in the bowel wall with preservation of the mucosa. Aetiology, clinical presentation, differential diagnosis and therapeutic options for intestinal obstruction due to endometriosis are discussed.

Inflammatory pseudotumor: a controversial entity.

Inflammatory pseudotumor of the lung is considered to be a rare, benign, neoplastic lesion, consisting mainly of spindle mesenchymal cells, sometimes in such a way that its histological appearance mimics that of a spindle cell sarcoma, fibrous histiocytoma or fibrosarcoma. On the occasion of a case managed in our department, the literature is reviewed, in an attempt to clarify some issues concerning this tumor. Emphasis is given to complete resection of the tumor for both diagnostic and therapeutic purposes. Malignant behavior may occur and recurrence is possible.

The role of transbronchial needle aspiration in the diagnosis of peripheral lung masses or nodules.

The purpose of this study was to evaluate the role of transbronchial needle aspiration (TBNA) in the diagnosis of peripheral lung lesions. We attempted to perform TBNA in 37 patients referred to our hospital for diagnostic evaluation of radiographically evident peripheral masses (23 cases) or nodules (14 cases). None of them had bronchoscopic evidence of endobronchial lesion. The aspirations were performed under fluoroscopic guidance, through a fibreoptic bronchoscope, employing a 21-gauge, 1.3 cm aspirating needle. They were preceded by bronchial brushing and followed by transbronchial biopsy (TBB) of the peripheral lesion. In two cases, the apical nodules were not accessible by any of these procedures. Bronchial washings were also collected immediately after each procedure (brush, TBNA and TBB). TBNA was diagnostic in 23 of 37 patients (62%) rendering the TBNA yield considerably higher than washing (24%), brushing (27%) or TBB (38%). The addition of TBNA to the combination of TBB, brushing and washing, significantly increased the yield of fibreoptic bronchoscopy in our series from 46% to 70%. No significant complications, such as pneumothorax or major bleeding, occurred either with TBNA or TBB. In conclusion, our findings suggest that transbronchial needle aspiration is a safe procedure, that can improve the diagnostic yield of bronchoscopy in the diagnosis of peripheral lung masses or nodules.
