1/842. Pseudomyxoma retroperitonei with spontaneous skin fistula.

    We describe the imaging features in a patient with pseudomyxoma retroperitonei arising from a mucinous carcinoma of the appendix with spontaneous development of a skin fistula. The thick wall and septa characteristic of pseudomyxoma were best demonstrated on gadolinium-enhanced magnetic resonance imaging. This patient illustrates (a) the potential of pseudomyxoma to cause skin fistula and (b) the possibility that this intraabdominal process can first present as a dermatologic complication. ( info)

2/842. Clinicopathological report: mucinous carcinoma of the eyelid.

    BACKGROUND: Mucinous carcinoma of the skin is a rare tumour that may involve the peri-ocular region. methods/RESULTS: A case report is presented of a 73-year-old woman with a right upper lid tumour, initially diagnosed as a basal cell carcinoma. Excisional biopsy of the residual tumour revealed mucinous carcinoma. Re-examination of the original pathology proved to be mucinous carcinoma, originating in the eyelid skin. Further treatment involved wide local resection and reconstruction. Systemic investigations were undertaken to exclude the possibility of metastatic mucinous carcinoma. CONCLUSION: This case is presented to alert ophthalmologists to the occurrence of this tumour in the periocular region, to highlight the importance of surgical excision with wide margins and the need for systemic investigation to exclude a primary malignancy in other sites, in particular the gastrointestinal system and breast.

3/842. Cytologic findings in noninvasive intraductal papillary-mucinous carcinoma of the pancreas. A report of two cases.

    BACKGROUND: Intraductal papillary-mucinous carcinoma of the pancreas is a new diagnostic term proposed by the 1996 world health organization classification of the exocrine pancreas. So far, there have been only a few reports concerning its cytologic findings, especially in noninvasive cases. CASES: The clinical and cytohistologic findings in two cases of noninvasive intraductal papillary-mucinous carcinoma of the pancreas were reviewed. Cytologic specimens were obtained from pure pancreatic juice in the dilated main pancreatic duct during the operation (case 1) and during endoscopic retrograde pancreatography (ERP) (case 2). Both cases showed three-dimensionally or individually scattered tumor cells with an increased nuclear/cytoplasmic ratio and prominent nucleoli. CONCLUSION: Our cases suggest that pancreatic juice cytology during ERP or surgery is useful in diagnosing pancreatic cancers and that it may detect noninvasive intraductal papillary-mucinous carcinoma of the pancreas.

4/842. Metachronous cancers or late recurrences after resection of stage I lung cancer.

    In 2 patients with stage I lung cancer, tumors recurred at their resection lines 10 years after the original surgical resections. These cases suggest that the prognosis of late cancer occurrences after resected primary lung malignancies might be related to the interval of time between primary and subsequent cancers rather than to their categorization as recurrent or metachronous cancers.

5/842. Malignancies in pediatric patients with ataxia telangiectasia.

    BACKGROUND: patients with ataxia telangiectasia (AT), known to have an inherent increased susceptibility to the development of cancer, may present with malignancies that are unusual for the patient's age, are often difficult to diagnose clinically and radiographically and respond poorly to conventional therapy. MATERIALS AND methods: We reviewed the clinical presentation and imaging studies of 12 AT patients who developed malignancies. RESULTS: Eight of the twelve patients developed non-Hodgkin's lymphoma (CNS, thorax, bone), two developed Hodgkin's disease, and two were diagnosed with gastrointestinal mucinous adenocarcinoma. CONCLUSION: The lymphomas were commonly extra nodal, and infiltrative rather than mass-like. The recognition of the tumors was often delayed due to confusion with the known infectious complications in AT patients. ( info)

6/842. Anaplastic nodules in an ovarian mucinous tumor. Case report and literature review.

    The case of a 38-year-old woman with an ovarian mucinous cyst that contained solid nodules of anaplastic carcinoma is described. Hitherto, only 17 cases of this aggressive type of ovarian tumor have been reported. The patient underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy and a para-aortic and pelvic lymphadenectomy. The tumor was classified as FIGO Stage Ic. On flow cytometry the tumor was dna diploid. Also, on image analysis the regions with well- differentiated carcinoma and the regions with anaplastic nodules were dna diploid. No adjuvant treatment was given. There is no evidence of disease 30 months after diagnosis. ( info)

7/842. Peritoneal mucinous carcinomatosis after laparoscopic-assisted anterior resection for early rectal cancer: report of a case.

    Minimally invasive colon surgery has been shown to be both technically feasible and a safe alternative to laparotomy. Its efficacy for the curative resection of colorectal cancer, however, remains controversial. Of major concern are the increasing reports of port-site recurrence after use of laparoscopic techniques in malignant disease. In this article a heretofore unreported complication of peritoneal mucinous carcinomatosis after laparoscopic-assisted anterior resection for early stage rectal cancer is presented. Isolated peritoneal recurrence is rare after curative resection of Stage I rectal cancer. The effect of pneumoperitoneum on tumor dissemination is discussed. ( info)

8/842. Calcification in mucinous cholangiocellular carcinoma.

    Calcification is rarely seen in cholangiocellular carcinoma. We herein report the case of a 53 year-old man with calcification in a cholangiocellular carcinoma. Because imaging studies had revealed coarse calcified foci, hepatolithiasis was suspected pre-operatively. The patient underwent a laparotomy in which intra-operative cholangioscopy revealed no gallstones but did reveal an unsuspected tumor with abundant mucin. A left hepatic lobectomy with resection of the extrahepatic bile duct was performed. The tumor histology was mucinous adenocarcinoma with calcification. In the English language literature, we found 9 cases of cholangiocellular carcinoma with macroscopic calcification. Six of these cases were mucinous adenocarcinomas. Roentgenologic examination revealed coarse calcification in 7 cases and fine calcification in 2 cases. Clinicians should note that cholangiocellular carcinoma, especially the mucinous variant, may be accompanied by coarse calcification. ( info)

9/842. Ganglioneuromatous polyposis of the colon associated with adenocarcinoma and primary hyperparathyroidism.

    A rare case of ganglioneuromatous polyposis of the colon found in association with mucinous adenocarcinoma and primary hyperparathyroidism caused by a parathyroid adenoma in a 77-year-old woman is described. We discuss the clinical implications of this finding and review the literature. ( info)

10/842. Mucinous carcinoma of the colon in a 16-year-old Turkish boy with bloom syndrome: cytogenetic, histopathologic, TP53 gene and protein expression studies.

    A 17-year-old Turkish boy with bloom syndrome (BS) developed mucinous carcinoma of the transverse colon. He was followed from 2 to 17 years of age. Increased sister chromatid exchanges (SCE) were observed, and he was diagnosed with BS at the age of 7. Sun-sensitive skin lesions were examined by skin biopsy, and histopathological studies of these lesions were done. During the follow-up period, an intraabdominal mass at the transverse colon was found, and mucinous carcinoma of colon was diagnosed at the age of 16. We examined TP53 protein expression from paraffin-embedded colon tissue of the patient with an immunohistochemical method. polymerase chain reaction products of exons 4-9 of the TP53 gene were examined by SSCP. No evidence of overexpression of TP53 protein or mutations of the TP53 gene was observed. The patient in this report is the first case with a mucinous carcinoma of colon diagnosed at an early age in the bloom syndrome Registry. Based on our results, carcinoma of the colon in BS patient may occur earlier than 35 years of age and the TP53 gene may not be directly related to carcinoma in bloom syndrome. ( info)
