BACKGROUND The aim of this study was to evaluate the degree of agreement among endosonographers for EUS diagnosis of neoplastic versus non-neoplastic pancreatic cystic lesions and the specific type of cystic lesion. METHODS Videotapes of EUS procedures from 31 consecutive cases of a range of histopathologically proven lesions, including mucinous cystic neoplasm, serous cystadenoma, neuroendoc...

A collision tumor is the co-existence of two adjoining but histologically distinct tumors without histological admixture in same tissue or organ. The most common combination ovary coexistence mature teratoma with mucinous cystadenomas. incidence adnexal mass pregnancy 0.05-2.4% which 94-99% are benign. 1-6% maybe malignant requiring more extensive surgical procedures that increases likelihood l...

The most usual form of the endocrine carcinoma is thyroid cancer (TC). In addition to papillary thyroid carcinoma (PTC), recent studies revealed incidence of RET/PTC rearrangement in other tumors, like Hürthle cell carcinoma (HCC) and even in non-carcinomatous disorders like Hashimoto's thyroiditis. Here, we present a case with concurrence of papillary thyroid carcinoma and Hürthle cell carcino...

DIAGNOSIS: A. All that is papillary in the bladder is not papillary urothelial neoplasia: i. Diagnostic pitfalls: papillary hyperplasia, nephrogenic adenoma, fibroepithelial polyp and papillary/polypoid cystitis ii. Artifacts: pseudopapillary folds and avulsed urothelium B. All urothelial proliferations that expand the lamina propria are not invasive carcinoma: i. Diagnostic pitfalls: florid vo...

Background: The most common types of true epithelial exocrine pancreatic cystic neoplasms are serous (SCNs), mucinous (MCNs), intra-ductal papillary (IPMNs), and solid pseudo-papillary (SPPNs). Both open laparoscopic surgeries major procedures with significant morbidity mortality rates. This study aimed to determine the outcomes surgery in managing terms postoperative fistula recurrence rate id...

Papillary thyroid carcinoma (PTC) is one of the most commonly diagnosed types of differentiated carcinoma of the thyroid. It is stated that lung is the most common site of metastasis followed by bone. The incidence of paranasal sinus (PNS) metastasis is fairly uncommon in case of thyroid carcinoma. To the best of our knowledge, no case of metastatic PTC to nasal cavity has been reported. In thi...

In 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mTc-MIBI scan is performed. The nodules are divided to hot (10), Warm (12) and cold (8). FNA reported papillary Ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary Ca and 3 benign lesions). All the nodules with no MIBI ...

Eosinophilic cholecystitis (EC) is a rare entity that presents in a manner comparable to acute cholecystitis. The diagnosis is based on classical symptoms of cholecystitis with the presence of eosinophils (>90%) within the gallbladder. EC has been reported alone (idiopathic EC) or in combination with manifestations such as eosinophilic cholangitis, hypereosinophilic syndromes, and parasitic inf...

Malignant papillary neoplasms of the breast comprise a number of microscopically distinct lesions, where apocrine metaplasia is commonly found in papillomas compared to other papillary lesions including papillary carcinomas. However, association of apocrine metaplasia in papilloma with Ductal Carcinoma in Situ (DCIS) is not very well defined. The lesions with apocrine metaplasia are not only di...

INTRODUCTION Mucinous tumors are the second most common form of epithelial ovarian tumor, yet the cell of origin for this histologic subtype remains undetermined. Although these tumors are thought to arise through a stepwise progression from benign cystadenoma to borderline tumor to invasive carcinoma, few studies have attempted to comprehensively characterize the genetic changes specific to th...
