1/384. Nevoid basal cell carcinoma syndrome.A case report of a young girl with nevoid basal cell carcinoma syndrome is presented. The patient showed cutaneous and skeletal findings characteristic of the syndrome. Multiple basal cell carcinomas, rib abnormalities, along with clinical evidence of frontal bossing and ocular hypertelorism were the primary features of the syndrome in this patient. It is suggested that other characteristics of the syndrome, such as jaw cysts, palmar and plantar pitting and calcification of the falx cerebri will develop as the patient grows older. Careful observation, particularly for medulloblastoma and malignant degeneration and invasiveness of basal cell carcinomas, will be an integral part of this young patient's care.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/384. birt-hogg-dube syndrome and Hornstein-Knickenberg syndrome are the same. Different sectioning technique as the cause of different histology.The autosomal dominant inherited syndromes of Hornstein and Knickenberg (HKS), and Birt, Hogg and Dube (BHDS) are both characterized clinically by the overall spread of multiple flesh coloured papules of the skin. However, it is a matter of debate if colonic neoplasms (adenomas as well as adenocarcinomas) are associated findings in the HKS or rather in the BHDS. Furthermore, histological differences are said to exist between the skin lesions in the two syndromes: whereas perifollicular fibromas were described in the HKS, fibrofolliculomas and trichodiscomas were found in the BHDS. In the present study, we report on a father and his daughter in whom we initially diagnosed a BHDS. We then examined a greater number of the papular lesions in histologic sections cut vertically as well as horizontally to the epidermis. Our results indicate that the histologic differences between the skin lesions in the two syndromes are artificial ones, caused by interpretation of different sectioning planes, and that consequently HKS and BHDS are the same. Therefore, it is necessary to look for colonic polyps in the syndrome in question, regardless if one prefers the name HKS or BHDS for it.- - - - - - - - - - ranking = 0.16708345964582keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
3/384. Germline hMSH2 and differential somatic mutations in patients with Turcot's syndrome.Turcot's syndrome is characterized clinically by the occurrence of primary brain tumor and colorectal tumor and has in previous reports been shown to be associated with germline mutations in the genes APC, hMLH1, and hPMS2. Here we describe three patients with Turcot's syndrome, each having colorectal adenocarcinoma and malignant glioma. All the colorectal and brain tumors from these patients showed replication errors in most of the microsatellite loci investigated. Search for underlying germline mutations in the nucleotide mismatch repair genes revealed three different hMSH2 mutations. All colorectal tumors showed a frameshift in the A(10) tract in the coding sequence of the transforming growth factor beta type II receptor (TGFBRII) gene, but no such change was detected in any of the brain tumors. frameshift mutation in the BAX gene was found in one colon carcinoma and mutations in insulin-like growth factor type II receptor (IGFIIR) gene in one glioma. Our data have broadened the possible mutation spectrum of patients with Turcot's syndrome. The difference in the mutation spectrum of TGFBRII, BAX, and IGFIIR between brain and colorectal tumors in these individuals suggests that the mutator phenotype may target different pathogenic pathways in the oncogenic process of the two organs.- - - - - - - - - - ranking = 0.30994060250296keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
4/384. Mutations of the adenomatous polyposis coli and p53 genes in a child with Turcot's syndrome.Turcot's syndrome is a rare heritable complex that is characterized by an association between a primary neuroepithelial tumor of the central nervous system and multiple colonic polyps. The aim of this study was to analyze genetic alterations in a case of Turcot's syndrome in a 10.5-year-old boy in whom a colorectal tumor developed 3.5 years following astrocytoma. An APC germline non-sense mutation at codon 1284 leading to a truncated protein was identified, as was a somatic p53 mutation in the colorectal carcinoma in exon 7, codon 244. The latter was not identified in the primary astrocytoma. However, immunohistochemistry revealed high p53 protein expression in both tumors, suggesting an additional p53 mutation in the primary astrocytic tumor. The diverse p53 mutations observed in this unique syndrome in two different sites and stages of the disease may shed light on the multistep progression of the malignant events.- - - - - - - - - - ranking = 0.14285714285714keywords = carcinoma (Clic here for more details about this article) |
5/384. Stewart-Treves syndrome in a patient with elephantiasis.Angiosarcoma that develops in areas of chronic lymphedema is also called Stewart-Treves syndrome. It usually appears in areas of lymphedema several years after mastectomy for breast carcinoma. Only 10% of these angiosarcomas occur in areas of chronic lymphedema as a result of another cause. We present a patient with epithelioid angiosarcoma as a rare complication of elephantiasis.- - - - - - - - - - ranking = 0.14285714285714keywords = carcinoma (Clic here for more details about this article) |
6/384. Turcot syndrome with colonic obstruction and small intestinal invagination: report of a case.We report herein the case of a 16-year-old boy diagnosed as having Turcot syndrome, otherwise known as glioma-polyposis syndrome. The patient was transferred from the Department of neurosurgery where he was undergoing investigation of a brain tumor, to the Department of medicine for investigation of gastrointestinal symptoms. The patient was diagnosed as having Turcot syndrome, and was then transferred to the Department of Surgery for treatment of an obstruction in the sigmoid colon and small intestinal invagination. A subtotal colectomy with side-to-end ileoproctostomy and release of the invaginations was carried out. Multiple polyps were found in the colon, two of which, including a large polyp that obstructed the colonic lumen, were confirmed histologically to be adenocarcinoma. The remaining polyps were adenomas. A biopsy of the brain tumor confirmed a diagnosis of astrocytoma (WHO grade II). This case report describes the characteristic features of Turcot syndrome presented by this patient.- - - - - - - - - - ranking = 0.16708345964582keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
7/384. muir-torre syndrome: case report of a patient with concurrent jejunal and ureteral cancer and a review of the literature.BACKGROUND: muir-torre syndrome is a rare autosomal dominant genodermatosis, first described in 1967, characterized by the presence of sebaceous tumors and an internal malignancy in the absence of other predisposing factors. OBJECTIVE: Our purpose was to review and update published literature on muir-torre syndrome. methods: We describe a 66-year-old white man with a history of sebaceous tumors and newly diagnosed transitional cell cancer of the right ureter and adenocarcinoma of the jejunum. The literature on muir-torre syndrome is reviewed by means of medline search and available published reports and updated. RESULTS: Only 205 cases of muir-torre syndrome with 399 internal malignancies have been reported. The common presentation is the presence of sebaceous tumors along with a low-grade visceral malignancy. Sebaceous tumors appeared before the internal malignancy in 45 cases (22%), concurrently in 12 (6%), and after the internal malignancy in 114 (56%). In 33 (16%) of 205 patients, a temporal relationship was not reported. The total number of sebaceous gland carcinomas reported is 44; 17 of 44 were neoplasms of the meibomian gland. Keratoacanthomas have been noted in 48 (23%) of 205 patients. Gastrointestinal cancers are the most common internal malignancies (61%), followed by genitourinary (22%). CONCLUSION: The presence of sebaceous tumors warrants a search for an internal malignancy. In patients with muir-torre syndrome, regular follow-up and search for new malignancy is mandatory. Evaluation and monitoring of the family members of patients are also necessary. patients and their families should be counseled for genetic testing. Genetic analysis of the primary tumor and skin lesions should be arranged as an added research tool if possible to better understand the disease.- - - - - - - - - - ranking = 0.30994060250296keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
8/384. Carcinoid syndrome caused by an atypical carcinoid of the uterine cervix.neuroendocrine tumors of the cervix are rare and are often under- or misdiagnosed. Because these tumors are very aggressive, early diagnosis and subsequent treatment are warranted. We describe a 46-yr-old woman with carcinoid syndrome caused by an atypical carcinoid of the uterine cervix. At age 44, she had dysplasia on Pap smear and underwent total abdominal hysterectomy with the diagnosis of adenocarcinoma. Fourteen months postoperatively, she developed the carcinoid syndrome and was found to have numerous liver metastases. Histological and immunohistochemical investigations of biopsy specimens from the patient's liver lesions and original cervical lesion ("adenocarcinoma") suggested that this woman had a primary atypical carcinoid of the uterine cervix with metastases to the liver. Treatment with octreotide and alkylating agents decreased the episodes of flushing and diarrhea within 8 weeks. If an adenocarcinoma of the uterine cervix is diagnosed, atypical carcinoid should be in the differential diagnosis. Symptoms of the carcinoid syndrome should be pursued and, if present, a urinary 5-hydroxyindolacetic acid level should be obtained. Timely diagnosis of a neuroendocrine tumor of the cervix may improve survival.- - - - - - - - - - ranking = 0.50125037893745keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
9/384. Sporadic Bazex-Dupre-Christol-like syndrome: early onset basal cell carcinoma, hypohidrosis, hypotrichosis, and prominent milia.BACKGROUND: We present the case of a 32-year-old woman with a large recurrent multifocal basal cell carcinoma on the scalp. Conspicuous accompanying symptoms were multiple periorbital milia, hypotrichosis of the body and the scalp, and hypohidrosis. The sparse hair of the scalp showed further abnormalities such as pili torti, as well as flattened, irregularly curly hairs. OBJECTIVE: In 1964, Bazex et al. described a syndrome characterized by congenital hypotrichosis, follicular atrophoderma, and basocellular neoplasms that included basal cell nevi and early onset basal cell carcinomas. The Bazex-Dupre-Christol syndrome is a rare X-linked dominant disease. A sporadic occurrence with the typical constellation of these symptoms has not yet been reported. The lack of a positive family history and no signs of follicular atrophoderma argues for a sporadic occurrence of a Bazex-Dupre-Christol-like syndrome. The case reported shares several features with the classic Bazex-Dupre-Christol syndrome. CONCLUSION: Our report documents the necessity to look for early development of basal cell carcinomas in patients who show signs of the epidermal malformations described.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
10/384. Recurrent rectoneovaginal fistula caused by an incidental squamous cell carcinoma of the neovagina in Mayer-Rokitansky-Kuster-Hauser syndrome.OBJECTIVE: Mayer-Rokitansky-Kuster-Hauser syndrome is a congenital malformation characterized by an absence of the vagina associated with a variable abnormality of the uterus and the urinary tract but functional ovaries. Surgical correction requires the creation of a neovaginal canal by the performance of a neovaginoplasty and an accurate long-term application of an artificial phallus phantom to avoid secondary shrinkage of the canal. Due to the chronic alteration of the posterior neovaginal wall, ulcers and consecutive fistulae may occur. We report the clinical course of a female who required surgical intervention for a rectoneovaginal fistula and developed a recurrence of the fistula due to one of the extremely rare squamous cell carcinomas of the neovaginal epithelium in order to show potential diagnostic and therapeutic features. METHOD: The systematic report of a case is presented. RESULT: Almost 13 years following the initial construction of a neovagina the patient developed a single-tract rectoneovaginal fistula. After surgical repair she represented with a recurrence due to a vast squamous cell carcinoma of the former operation site. Tumor en bloc resection was performed and currently (follow-up: 4 months) she has no signs of new tumor progression. CONCLUSION: Creation of a neovagina is the standard procedure for treating vaginal atresia or aplasia. Because of the long clinical course postoperatively, complications may occur. This report of a case of a malignant transformation in neovaginal epithelium shows the potential risk of malignancy and underlines the necessity of a close follow-up.- - - - - - - - - - ranking = 0.85714285714286keywords = carcinoma (Clic here for more details about this article) |
