Background: Autoimmune diseases like pemphigus and systemic lupus erythematosus are protective against skin malignancies like basal cell carcinoma and squamous cell carcinoma. Objective: As vitiligo is an autoimmune diseases, the aim of the present work is to record the frequency of all benign and malignant skin tumors among patients with different severity of vitiligo and to be compared with the skin tumors in healthy control. Patients and Methods: This is a case series, descriptive study done in the Department of Dermatology—Baghdad Teaching Hospital, Baghdad, Iraq, during the period from May 2014-May 2015. History was taken from each patient with vitiligo regarding age, gender, duration, personal and family history of vitiligo and other autoimmune diseases such as diabetes mellitus, thyroid dysfunction, and alopecia areata. Patients were assessed for past and present history of photodermatosis and any skin cancers. Healthy control was considered. Results: Three hundred and fifty patients with vitiligo were included in this study: 50 patients with universal vitiligo, 100 patients with generalized vitiligo, and 200 patients with localized vitiligo as well as 500 subjects as a healthy control. The ages of all studied subjects ranged between 31 and 77 years. Twenty four(48%) patients with universal vitiligo were males and 26 (52%) were females;49(49%) patients with generalized vitiligo were males and 51(51%) were females;101(50.5%) patients with localized vitiligo were males and 99(49.5%) were females and 235(47%) of control were males and 265(53%) were females. All skin tumors were seen to be high in healthy subjects and lower or absent in patients with vitiligo. Also patients with mild vitiligo had a higher frequency of skin tumors including benign and malignant than patients with severe vitiligo especially in patients with universal vitiligo. In addition, no photosensitivity or actinic reticuloid was detected in patients with vitiligo. Conclusions: Vitiligo especially generalized and universal type as an autoimmune disease had a protective action against photodamage, photosensitivity and skin tumors whether benign or malignant. 展开更多

Cancer is one of the leading causes of death worldwide and breast cancer is the most commonly diagnosed cancer among women. An increased incidence of different types of breast cancer has been reported. This study was designed to evaluate the different types of breast cancer and its possible risk of neoplasmic transformation to an advanced malignant stage from a benign tumor. The histochemical patterns of collagen fibers in the benign and malignant breast lesions were evaluated. From the 50 tissue samples, 25 were malignant breast lesions and 25 were benign breast tumor. Hematoxylin and Eosin (HE), Van Gieson staining were performed to detect a benign and malignant tumor as well as collagen fibers. We found that significant cases after age of 35 were associated with ductal carcinoma while most of the cases within the age of 25 years were associated with fibrocystic changes. The intensity of collagen fiber was higher to Ductal Carcinoma while negative and less intense for Fibroblastic changes. Furthermore, a consistent association of other lesions, such as Lobular Carcinoma, Fibroadenoma, Papilloma and Fat necrosis and noticeable staining for collagen was observed for the different lesion. Our study suggested that women with age of 25 with benign lesion of fibrocystic change and ductal carcinoma are highly susceptible to develop advanced malignant tumor with age. Therefore, quantitative measurement of collagen fiber and regular follow-up are recommended to avoid the possible risk of developing advanced malignant lesions. 展开更多

Objective: To evaluate the efficacy and safety of the immunosuppressant treatment among 10 post-renal transplantation recipients with malignant tumors. Methods: Conversion to sirolimus (SRL) treatment was performed for 10 cases which had found malignant tumors after kidney transplantation. During the follow-up period, the recurrence and diffusion of the tumor, the renal function and rejection were monitored. Results: All these cases despite the death had been followed up for at least 1 year. 9 cases had no recurrence and diffusion. 1 case died due to the tumor diffusion 7 months after the drug conversion. 1 case suffered once acute rejection 2 months after the drug conversion. This acute rejection had been inhibited by flushing dose MP. Conclusion: As a new immunosuppressant, SRL not only can prevent the generation of AR, but inhibit proliferation and development of malignant tumors in kidney transplantation recipients as well. 展开更多

Purpose: We aimed to make a fast and accurate distinction of malignant and benign lesions in cases with predominantly solitary or multifocal involvement using latest technology software and hardware systems in computed tomography. Materials and Methods: 53 cases were included in the study. Primary (n = 42, 31 benign, 11 malignant) or metastatic (n = 11) tumors were detected at various locations in the bone structure of the cervical to coccygeal vertebrae in all cases. 3D CT images taken using the same system and biopsy or post-operative histopathology findings were available for all cases. Thin section images taken retrospectively from the archives were converted to 3D images using the same program and parameters, which were then recorded in the same window settings by two radiologists. Only 3D images were then analyzed to investigate the presence or absence of the dirty interface sign. Results: Dirty interface sign was present in 17 malignant lesions and absent in the remaining 5 lesions. As for benign lesions, the sign was present in only two lesions and the remaining 29 were negative for the sign. There was a high level of consistency between the two radiologists. In conclusion, malignant and benign lesions affecting the bone spinal axis were distinguished based on the presence or absence of the dirty interface sign with 77.3% sensitivity, 93.5% specificity and 86.8% accuracy. Conclusion: When evaluated with standard bone window views, 3D views can be used successfully for the distinction of malignant and benign bone tumors. At least, 3D views generated using low dose regimes in highly developed systems can be used with similar purpose to that of diffusion weighted MRI sequences that give roughly outlined but fast and accurate information about the lesion. 展开更多

Objectives: The aim of the investigation was to study the hormonal status (sex hormones: estradiol (E2), progesterone (P), testosterone (T);non-sex gonadotropic hormones-luteinizing hormone (LH) and follicle-stimulating hormone (FSH)) of women with benign and malignant tumors of uterine body in the reproductive, menopause and postmenopause periods. Also the distribution features of the blood ABO system phenotype groups and their link to the development of uterine body tumors have been studied. Methods: The determination of hormones was made by the enzyme analysis method (ELAIZA), provided by the proper ELAIZA kits. For the study of blood ABO system antigens, internationally recognized immunoserology methods were used. Results: Investigations revealed the increased level of E2 and T on the background of the reduced P in the blood of the women with uterine tumors in the reproductive, menopause and post-menopause period. As for gonadotropic hormones, the decreased levels of LH and FSH have also been detected. From the ABO system phenotype groups A(II) group had the highest frequency between the women with malignant uterine tumor in the reproductive age. O (I) phenotype group was the most frequent in case of menopause and post-menopause women with uterine malignant tumors. Conclusions: Hormonal imbalance creates good conditions for the proliferation of uterine tissues and hence causes the development of benign and malignant uterine tumors. The imbalance of the sex steroid and gonadotropic hormones in the blood of post-menopause women indicates on the genotoxic mechanism of cancer development on the background of age-related changes. A(II) group had the highest frequency between the reproductive age women with uterine malignant tumor, while O (I) group was the most frequent in case of menopause and post-menopause patients. 展开更多

This review is part two of three, which will present an update on the classification of gastrointestinal submucosal tumors. Part one treats of the diagnosis and part three of the therapeutic methods regarding gastrointestinal submucosal tumors. In the past there has been some confusion as to the classification of gastrointestinal submucosal tumors. Changes in classifications have emerged due to recent advances in mainly immunohistochemistry and electron microscopy. The aim of this paper is to update the reader on the current classification. Literature searches were performed to find information related to classification of gastrointestinal submucosal tumors. Based on these searches the twelve most frequent submucosal tumor types were chosen for description of their classification. The factors that indicate whether tumors are benign or malignant are mainly size and number of mitotic counts. Gastrointestinal stromal tumors are defined mainly by their CD117 positivity. In the future, there should be no more confusion between gastrointestinal stromal tumors and other types of submucosal tumors. 展开更多

AIM: To describe the histopathologic and clinical features of eyelid tumor cases from Tianjin Eye Hospital during 2002 to 2015. METHODS: In this retrospective study, a total of 2228 cases of eyelid tumors with pathologic diagnoses were enrolled. The eyelid tumors were classified into three groups according to tumor origin: epidermal, adnexal and miscellaneous, including melanocytic, neural and vascular lesions. Inflammatory tumor-like lesions were excluded. The clinical characteristics of the eyelid tumors were analyzed, including age, gender and lesion location. RESULTS: Most eyelid tumors were epidermal in origin(1080, 48.5%), followed by miscellaneous(885, 39.7%) and adnexal tumors(263, 11.8%). Among all the tumors, 292(13.1%) were malignant lesions, 1910(85.7%) benign and 26(1.1%) premalignant lesions. Most malignant tumors originated from epidermal cells(60.0%), followed by adnexal cells(34.6%). The most common malignant tumors were basal cell carcinomas(56.5%) followed by sebaceous carcinoma(34.6%), squamous cell carcinomas(3.8%) and lymphoma/plasmocytoma(1.7%). The benign and premalignant eyelid lesions mostly originated from epidermal cells(46.4%) followed by miscellaneous cell sources(45.2%), including melanocytic nevus(33.8%), seborrheic keratosis(13.7%), squamous cell papilloma(13.0%) and epidermal cysts(11.5%). CONCLUSION: Eyelid tumors are mostly epithelial in origin. Benign tumors are significantly more common than malignant tumors with an obvious female predominance, and the most frequent malignant tumor are basal cell carcinoma, sebaceous carcinoma and squamous cell carcinomas. The tumor clinical features varied among the different subtypes. 展开更多

BACKGROUND:Pancreatic tumors located in the neck region usually require pancreaticoduodenectomy or splenopancreatectomy.For small benign tumors enucleation is not usually feasible due to their size and localization;then pancreatectomy is often needed.Central pancreatectomy consists of a limited resection of the midportion of the pancreas and can be offered in benign and low-grade malignant tumors of the neck of the pancreas.The study aimed to evaluate whether central pancreatectomy has a place in pancreatic surgery. METHODS:In this study,which covered a period of 14 months,we performed central pancreatectomy in four selected patients.Preoperative evaluation and operative frozen section biopsy in indicated cases allowed proper selection for the procedure.Operative details,complications and follow-up were recorded. RESULTS:Four patients,two with serous cystadenoma,and one with an islet cell tumor,and one with a hydatid cyst, were identified for the procedure.The mean tumor size was 3 cm,the mean operative time was 217.5 minutes,and the mean blood loss was 382.5 ml.There was no morbidity or mortality in this series.No endocrine or exocrine deficiency was observed in any patient during a mean follow-up of 22.7 months. CONCLUSIONS:Central pancreatectomy is a procedure that offers excellent results in benign and low-grade malignant tumors.It preserves functional elements(endocrine and exocrine)of the pancreas and also eliminates the infective and hematological effects of splenectomy.Thus,central pancreatectomy should be included in the armamentarium of pancreatic surgery,and in order to obtain good results,proper indications and adequate experience are recommended. 展开更多

BACKGROUND Duodenal papillary tumor is a rare tumor of the digestive tract,accounting for about 0.2%of gastrointestinal tumors and 7%of periampullary tumors.The clinical manifestations of biliary obstruction are most common.Some benign tumors or small malignant tumors are often not easily found because they have no obvious symptoms in the early stage.Surgical resection is the only treatment for duodenal papillary tumors.At present,the methods of operation for duodenal papillary tumors include pancreatoduodenectomy,duodenectomy,ampullectomy,and endoscopic resection.CASE SUMMARY A 47-year-old man was admitted to because of a duodenal mass that had been discovered 2 mo previously.Electronic gastroscopy at another hospital revealed a duodenal papillary mass that had been considered to be a high-grade intraepithelial neoplasia.Therefore,we conducted a multidisciplinary group discussion and decided to perform a pancreas-preserving duodenectomy and a R0 resection was successfully performed.After surgery,the patient underwent a follow-up period of 5 yr.No recurrence or metastasis occurred.CONCLUSION According to our experience with a duodenal papillary tumor,compared with pancreaticoduodenectomy,the use of pancreas-preserving duodenectomy can preserve pancreatic function,maintain gastrointestinal structure and function,reduce tissue damage and complications,and render the postoperative recovery faster.Pancreas-preserving duodenectomy for treatment of a duodenal papillary tumor is feasible under strict control of surgical indications. 展开更多

The size and complexity of its observations are the major problems that lead to false diagnoses. Even experienced doctors can make a mistake in causing terrible consequences for the patient. We propose a mathematical tool for the diagnosis of breast cancer. The aim is to help specialists in making a decision on the likelihood of a patient’s condition knowing the series of observations available. This may increase the patient’s chances of recovery. With a multivariate observational hidden Markov model, we describe the evolution of the disease by taking the geometric properties of the tumor as observable variables. The latent variable corresponds to the type of tumor: malignant or benign. The analysis of the covariance matrix makes it possible to delineate the zones of occurrence for each group belonging to a type of tumors. It is therefore possible to summarize the properties that characterize each of the tumor categories using the parameters of the model. These parameters highlight the differences between the types of tumors. 展开更多

Nephroblastoma is the most common malignant renal tumor in children and is related to an abnormal proliferation of cells resembling those of the embryonic kidney (metanephroma), hence the terminology;embryonal tumor. These are tumors that remain and remain unstudied in Mali because they are common in adults in our context. Its annual incidence is estimated at approximately 1/10,000 births. Nephroblastoma is a rare or even exceptional tumor in adults. The clinical manifestation was a large swelling of the right hypochondrium;abdominal pain for a year;unquantified fever, hypertension, initial hematuria associated with burning during urination and anemia. The main clinical manifestation remained fever and abdominal pain. This renal tumor posed a diagnostic problem which was previously labeled as a mesenteric tumor in our general surgery department. The diagnosis was made by imaging: CT and magnetic resonance imaging. The treatment is multidisciplinary and combines chemotherapy, surgery with or without radiotherapy. The prognosis is poor due to late diagnosis and less effectiveness of chemotherapy compared to the child. Survival did not exceed a year and a half because the renal tumor in our patient was surgically overcome. We report a case of nephroblastoma in an 86-year-old patient with unfavorable histology (hematogenous metastases), operated on in the general surgery department and whose postoperative course was simple and who was referred to oncology for treatment. 展开更多
