A CASE OF CARDIAC COMPRESSION BY HEPATIC CYST IN A WOMAN WITH POLYCYSTIC KIDNEY DISEASE.
2008
Liver cysts are common extrarenal manifestations of autosomal dominant polycystic kidney disease (ADPKD). They occur more frequently in women, and are also more in number and larger in size, than in men. Liver cysts tend to develop slower than the kidney cysts; their number and size increases with the age (worsening kidney function), number of pregnancies, and estrogen assumption. Although most patients with ADPKD report no liver symptoms, sometimes, chronic manifestations related to progressive increase of the polycystic liver are experienced. The quality of life can be severely impaired with huge hepatomegaly causing abdominal distension, pain, dyspepsia, dyspnoea, fatigue, physical and e…
Quiste broncogénico de localización excepcional que simula una tumoración pancreática
2010
We report a 37-year woman with a history of acute cholangitis in whom a bronchogenic cyst was misdiagnosed as a pancreatic neoplasm on the basis of the clinical and radiological findings. Infradiaphragmatic bronchogenic cysts are rare and can sometimes mimic a pancreatic carcinoma.
Is the stripping technique a tissue-sparing procedure in large simple ovariancysts in children?
2008
Abstract Background Stripping of the cystic wall is performed by gynecologists to treat large ovarian cysts. Information in the pediatric population is poor. We prospectively evaluated the pathologic specimens of large ovarian cyst to determine whether the stripping technique is a tissue-sparing procedure even in this age. Methods We evaluated 5 patients. Samples were taken from the intermediate part of the cystic wall and from the layer covering the cyst during excision. The presence of ovarian tissue adjacent to the cyst wall, and the morphological features of the surrounding tissue were both evaluated. Pelvic ultrasound follow-up was also performed. Results Patients' mean age was 4.5 yea…
Adenoid Cystic Carcinoma of Salivary Gland: An Immunohistochemical Study
2019
Xanthogranulomatous Cholecystitis
1990
Summary Xanthogranulomatous cholecystitis (XC) is a chronic inflammatory lesion of the gallbladder histologically characterized by the presence of varying amounts of foamy histiocytes in the inflammatory infiltrate. In this study a review of 63 cases selected from 1207 surgically removed gallbladders is presented; the percentage found (5.2%) is slightly higher than that of previous reports showing that XC is less uncommon than generally believed. A detailed microscopic study is performed: the authors observed according to the histological features particularly the different patterns of distribution of the inflammatory infiltrate and postulate the existence of three subtypes of XC: multinodu…
Unusual epithelial-myoepithelial carcinoma in palate: case report and immunohistochemical study
2010
Ephitelial-myoepithelial carcinoma (EMC) is a neoplasm of salivary gland extremely rare and low-grade malig- nant, exhibiting predilection for major salivary gland, especially parotid gland. This paper described a case of EMC localized in soft palate. The initial clinical diagnosis were mucoepidermoid and adenoid cystic carcinoma. A incisional biopsy was performed, and the histological diagnosis was adenocarcinoma not otherwise specified. The patient underwent excisional biopsy, where was realized immunohistochemical analysis, staining the duct-like structures, where the inner layer of epithelial cells positively for CK 14, whereas outer layer of myoepithelial cells stained positively for s…
Histological changes in odontogenic parakeratinized keratocysts treated with marsupialization followed by enucleation
2020
Background The purpose of this study was to evaluate whether marsupialization treatment induces changes in the histology of odontogenic keratocyst epithelium and to compare our experience with the literature. Material and Methods A retrospective revision of histological samples was performed. 5 patients with odontogenic keratocyst treated with marsupialization follow by enucleation were selected. Histologic evaluation analyzed the changes in the keratocyst epithelium after marsupialization in terms of type of keratinization, thickness of the epithelium and connective tissue, the presence of acanthosis, the presence and grade of fibrosis, the type and grade of inflammation and the presence a…
Parotid lymphoepithelial cyst in non-HIV patient
2011
The lymphoepithelial cyst is a dysontogenic benign cyst originated from the epithelial remnant retained inside the lymphoid tissue during the embryogenesis that occurs in the lateral neck region and, less frequently, in the oral cavity and in the parotid gland. The parotid gland evolvement increased significantly after the HIV discovery and it is related to ductal obstruction phenomenon that goes along with a follicular hyperplasia in the periductal parotid lymph nodes. However, lymphoepithelial cysts are rare in non-HIV patients. Treatment options are controversial and might include cystic content aspiration, sclerosis-therapy, radiotherapy and surgery. Enucleation of the cyst while preser…
Das basaloide Plattenepithelkarzinom (BSC) der Mundschleimhaut
1997
The basaloid-squamous carcinoma (BSC) that was first described in 1986 by Wain et al. for the head and neck region is a rare distinct variant of squamous cell carcinoma (SCC). The cardinal histopathologic feature is a biphasic cellular pattern of basaloid and squamous components. BSC has been confused with solid adenoid cystic carcinoma (ACC). Although the number of reported cases is small, BSC appears biologically virulent, with a propensity to aggressive local behavior, early regional and distant metastasis, and subsequent poor survival. We report the clinicopathological characteristics of 4 new cases and compare their immunohistochemical features with those of solid ACC and conventional …
