[Video-assisted thoracoscopic surgery in 3 cases of adult cystic adenomatoid malformation].

Congenital cystic adenomatoid malformation involving the lung is a rare hamartomatous condition that is usually diagnosed in the neonatal period. The presentation of this malformation in older patients is exceptional and usually manifests in a series of recurrent lung infections affecting a single lobe or segment. The treatment of choice is complete surgical exeresis. This report of 3 cases of late presentation focuses on the surgical approach used and the unusual manifestation of recurrent spontaneous pneumothoraces in 1 patient. The patients were females aged 15, 16, and 25 years with histories of various respiratory diseases (extrinsic asthma, recurrent pneumonias, and pneumothoraces). The patients were referred to us for surgery with suspected diagnoses that were different from the final diagnoses in all cases. All underwent diagnostic video-assisted thoracoscopy to explore the affected hemothorax, and definitive treatment was possible during the procedure for 2 patients (a lobectomy and an atypical segmentectomy) by video-assisted surgery. The third patient underwent lobectomy by lateral thoracotomy after exploratory video-assisted thoracoscopy. Short- and long-term outcomes were excellent for all 3 patients.

[Synchronous prostatic carcinosarcoma: report of 2 cases and review of the literature].

OBJECTIVE: Carcinosarcoma of the prostate is a biphasic tumor containing adenocarcinoma and recognisable sarcomatous components. It is a rare neoplasm with less than 40 reported cases. We describe two additional examples showing carcinosarcoma in the initial pathologic material (synchronous presentation). METHODS AND RESULTS: The patients were 71 and 78 year-old, respectively. The primary prostatic tumour in case one was composed of adenocarcinoma admixed with a neoplastic mesenchymal component that displayed foci of chondrosarcoma, rhabdomyosarcoma and angiosarcoma. The adenocarcinoma in the second case was admixed with spindle cell sarcoma and chondrosarcoma. Both patients died of disease after surgery, 3 and 9 months respectively. CONCLUSION: Synchronous carcinosarcoma of the prostate is a highly malignant neoplasm that may need an aggressive therapy.

[Pathological anatomy of neoplasms of the pancreas. I. Tumors of the exocrine pancreas].

The authors make a review of the exocrine pancreas tumors describing the main clinical, pathological and histogenetic features. The benign neoplasms develop generally from the ductal epithelium and may be cystic or mucinous, the last type suffering some times a malignant transformation. The malignant tumors are very common; histogenetically they may be ductal, acinar or of uncertain origin. Tumor localization, size and invasion are to be taken into consideration for the prognosis.

Metastatic glioblastoma multiforme in cervical lymph nodes. Report of a case with diagnosis by fine needle aspiration.

Metastatic glioblastoma multiforme is a rare event usually seen in patients with previous and repeated surgery. Fine needle aspiration from enlarged lymph nodes in a patient with cerebral glioblastoma multiforme showed a highly cellular smear with dispersed single cells and cell clusters. The cells had marked pleomorphism, hyperchromasia, coarse chromatin, prominent nucleoli and occasional intranuclear cytoplasmic inclusions. Multinucleate giant cells and marked endothelial proliferation were also seen. The diagnosis of metastatic glioblastoma multiforme was supported by immunohistochemistry, which showed many cells with thick and large cytoplasmic processes with intense immunoreactivity to glial fibrillary acid protein. The differential diagnosis with other metastatic small cell tumors is discussed.

[Echoendoscopy: pathological diagnosis using real-time puncture-aspiration].

The aim of this study was to obtain pathologic diagnosis by aspiration punction (AP) by real time lineal echoendoscopy in different lesions suspected to be malignant. AP was performed in 6 cases with a Pentax-Hitachi FG 32UA lineal echoendoscopy. Four pancreatic neoplasms, one plastic linitis and one adenopathy of the celiac trunk were observed. Malignancy was confirmed by clinical evolution or surgery. The sensitivity of malignancy diagnosis was 67%, specificity 100% and diagnostic certainly 87%. No complications were observed. In the authors' preliminary experience, aspiration punction with real time lineal echoendoscopy allowed pathological diagnosis to be performed safely and effectively with relative simplicity.
