May mimic mucinous cystic neoplasm if in intrapancreatic accessory spleen. Called epithelioid / epidermoid if squamous lining. Origin unknown; may derive from metaplasia in mesothelial cysts ( Am J. Definition / general. Rare; cysts lined by mesothelial cells in vicinity of kidney that may present as renal masses. Also called primary retroperitoneal cysts of mesothelial origin Inclusions of benign mesothelial cells in lymph nodes Often missed on routine H&E sections (Am J Surg Pathol 1999;23:1264) Hyperplastic mesothelial cells in nodal tissue may derive from reactive serosal mesothelium that is dislodged into draining lymphatics (Arch Pathol Lab Med 2000;124:609) Often associated with serosal fluid collection (pericardial, pleural, abdominal) at time of nodal.
The diagnosis and treatment of mesenteric cysts is challenging due to rarity, lack of specific symptoms and variability in location and size. This report aims to discuss current diagnostic and treatment strategies. A 35-year-old woman presented with non-specific abdominal pain. CT revealed a 5×5×3 cm septated abdominal cyst (figure 1) Splenic cysts (including true cysts, pseudocysts and parasitic cysts) and hamartomas are common benign proliferations which generally pose little problems in their identification. More challenging is the diagnostic workup of spindle cell and inflammatory rich lesions of the spleen, whose correct identification is crucial Lymphocyte hyperplasia of the spleen is an increase in the number of lymphocytes outside the range of normal compared with concurrent controls. The result can be variable increases in the area and number of white pulp elements (periarteriolar lymphoid sheaths [PALS], follicles, and/or marginal zones) ( Figure 1 and Figure 2 , arrows)
A case of mesothelium‐lined cyst of the adrenal gland is reported. Although more than 300 adrenal cysts have been reported in the literature, epithelial cell‐lined cysts are rare and comprise only 9% of the cases. An adrenal cyst was found, the lining cells of which had features consistent with mesothelial cells. The inner surtace of the cyst was lined by a single layer of cuboidal cells. Hydatid Cyst Peritoneum accounts for 13% of hydatid cysts in abdomen, likely reflecting sequelae of hepatic or splenic hydatid cyst rupture Appearance is similar to hydatid cysts in liver/spleen, with acute phase characterized by dominant cystic mass with internal daughter cysts or wavy, serpiginous internal densities (water-lily sign Primary cardiac and pericardial neoplasms are clinically significant lesions, with potential life-threatening sequelae that affect patients of all ages. Most benign neoplasms are curable with surgery, and therefore radiologic detection and characterization is critical. The early diagnosis of malignant neoplasms plays a role in palliation
. Introduction. Myometrial cysts are rare and consequently little information on them has been reported in the literature. There have been handfuls of case reports focusing on specific diagnostic entities, namely cystic adenomyosis [, , ], but there is no case series encompassing the range of pathology encountered.We describe a series of1 myometrial cysts detected either on imaging or at. Higher magnification shows flattened mesothelial cells lining small and large cystic spaces. The nuclei are bland and mitotic figures are absent.

Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) is the optimal method for sampling lesions of the pancreas. This procedure is being performed at increasing numbers of hospitals and therefore, more and more cellular pathology departments are having to process and report EUS-FNAB specimens. This article outlines the advantages of using tissue/cell block preparation to. Tumor-Like Lesions Inflammatory and Reparative Lesions Granulomatous Peritonitis ( Figs. 20.1-20.2 ) Granulomatous peritonitis, which can be caused by a variety of infectious and noninfectious agents, can result in peritoneal nodules, potentially mimicking disseminated cancer.

Notes: Peritoneal mesotheliomas make up only 5-10% of all malignant mesotheliomas. The vast majority (90-95%) of mesotheliomas involve the pleural cavity. Most cases occur in adults (>40 yrs.) with a male predominance. About 50% of patients have history of heavy asbestos exposure Incidence. It is difficult to discern how many annual deaths occur due to adenocarcinomas of Mullerian origin. While EOC caused approximately 14,030 deaths in the United States in 2013  and 151,905 deaths worldwide in 2012 , it is unclear exactly how many deaths were caused by peritoneal and tubal cancers.Peritoneal and tubal carcinomas have been considered rare malignancies and separate.
Bernard Naylor, in Comprehensive Cytopathology (Third Edition), 2008. Cytology. Histiocytes are found in various proportions in almost every serous effusion. Their size varies considerably, from about 15 to 100 μm in diameter, with most within the range of 20 to 40 μm. In smears, the typical histiocyte is easily identified by its size, eccentric round or bean-shaped nucleus, and lightly. Ditzels. Tonsils (at cut-up) are a common ditzel.

General Features of Epithelial Ovarian Tumors Approach to Ovarian Tumor Diagnosis ( Tables 13.1 and 13.2 ) As this is the first chapter considering ovarian tumors, some remarks concerning their evaluation are appropriate.

Peritoneal cancer is a rare cancer. It develops in a thin layer of tissue that lines the abdomen.It also covers the uterus, bladder, and rectum.Made of epithelial cells, this structure is called. The epithelial cells lining the inclusion cysts secrete somatic growth factors that lead to the development of OEC. It is worth noting that the histomorphologic features of ovarian cancers resemble those of müllerian tumors rather than mesothelial tumors

In most circumstances, it is a misnomer because a mass actually exists, and hence, the term pseudoneoplasm would be more appropriate. However, there may still be circumstances in which the term pseudotumor is applicable, and some scenarios are. Historically, pathology departments have required consent for examination of intact fetuses 20 weeks or greater and consider these to be autopsy specimens; however, because the tissues acquired by D&E are the result of a surgical procedure and do not produce an intact fetus, they are generally examined in surgical pathology OUTLINES IN PATHOLOGY. download Report .

Leiomyosarcoma is a malignant smooth muscle tumor.A benign tumor originating from the same tissue is termed leiomyoma.While leiomyosarcomas are not thought to arise from leiomyomas, some leiomyoma variants' classification is evolving. About one in 100,000 people get diagnosed with leiomyosarcoma (LMS) each year. LMS is one of the more common types of soft-tissue sarcoma, representing 10 to 20%. Nevertheless, numerous imaging pitfalls exist, particularly in women, which may result in the wrong diagnosis. In addition to other bowel pathology (e.g., diverticulitis), acute gynecological disorders such as torsion, endometriosis, ruptured ovarian cyst and tuboovarian abscess may look similar to appendicitis or appendiceal abscess The mesothelial lining lateral to the genital ridge invaginates, forming the Müllerian ducts from which the fallopian tubes, uterus, and upper vagina arise.
