Abstract

Vascular surgical techniques were applied to the radical resection of carcinoma of the liver, biliary tract and pancreas. Distal and proximal portal vein reconstruction, respectively, was carried out in 16 patients with carcinoma of the pancreas and 16 with cancer of the liver and biliary tract. Hepatic vein trunks with tumour involvement were resected and reconstructed by various techniques in six patients. A suprarenal segment of the inferior vena cava was completely replaced by a prosthetic graft in three patients with retroperitoneal malignancy. Venous surgery increased the resectability of malignant tumours and preserved circulation in the organ remnant, although the long-term effect on survival is not yet clear. Vascular surgical techniques should be applied more widely in the field of general abdominal surgery.

Sister Mary Joseph's nodule as presenting sign of a desmoplastic small round cell tumor.

Umbilical metastases, also named Sister Mary Joseph's nodules, are well documented in the adult population and most often represent an underlying intra-abdominal malignancy, usually a carcinoma of gastrointestinal or gynecologic origin. They are indicative of widespread abdominal disease and are associated with a poor prognosis. An extensive review of the literature reveals only two such presentations in the pediatric population. A 14-year-old male presented with an umbilical mass, which was found to be a metastatic lesion of a desmoplastic small round cell tumor (DSRCT) of the abdomen. The diagnosis of an intra-abdominal malignancy, most commonly a DSRCT, should be considered in the presence of an umbilical mass in a child.

Cytology of desmoplastic small round-cell tumor: comparison of pre- and post-chemotherapy fine-needle aspiration biopsies.

BACKGROUND: Desmoplastic small round-cell tumor (DSRCT) is an aggressive malignancy of young adults, which is amenable to fine-needle aspiration biopsy (FNAB). As this entity is increasingly recognized and biopsied, cytopathologists are compelled to become familiar with the range of cytologic features of DSRCT. In addition, postchemotherapy tumors may be sampled to confirm disease recurrence before planning additional therapy. This study was designed to compare prechemotherapy and postchemotherapy cytomorphology of DSRCT and to evaluate for distinct chemotherapy-induced changes. METHODS: The authors searched their respective institutional databases for all DSRCT cases with an associated FNAB. FNAB slides, immunocytochemistry, and cytogenetic results were reviewed. RESULTS: Six aspirates from 5 patients were identified, 3 of which were postchemotherapy. The postchemotherapy cases demonstrated cytologic findings not typically described in DSRCTs, including prominent and conspicuous nucleoli, discohesive single-cell architecture, and slightly larger cell size. CONCLUSIONS: Cytomorphologic variability was prominent in prechemotherapy cases, and no case could be classified as DSRCT on cytology alone; immunohistochemistry was necessary for definitive diagnosis. Chemotherapy increased the spectrum of cytologic features. The most notable difference between the 2 groups was a predominantly discohesive single-cell pattern with conspicuous nucleoli in the postchemotherapy group, instead of the clustering pattern of medium-sized cells with inconspicuous nucleoli typically attributed to de novo cases reported in the literature.
