Kit Is Expressed by Epithelial Cells In Vivo

2003

In mammalian skin, stem cell factor (SCF) regulates the proliferation and maturation of mast cells and melanocytes, which are thought to be the only cutaneous cells that express the Kit-tyrosine kinase receptor (Kit) and respond to epithelial and mesenchymal-derived SCF. We previously had noted, however, the presence of Kit+ cells in murine hair follicles, in an introepithelial tissue compartment devoid of melanocytes and mast cells. Here we have identified the nature of this Kit+ population of cells in hair follicles of C57BL/6 mice. Anagen hair follicles showed strong Kit immunoreactivity not only in the pigmentary unit above the follicular dermal papilla but also in a much more proximall…

Papillary cystoadenoma lymphomatosum (Warthin-like) of minor salivary glands

2009

Papillary cystadenoma lymphomatosum is a benign salivary gland tumor most frequently located in the parotid gland (Warthin?s tumor). Its presentation in other major, or in minor, salivary glands is rare. Clinically, it manifests as a slow growing tumor, fluctuant on palpation due to its cystic morphology. The treatment of choice is complete excision with wide tumor-free margins. We present a 73-year-old female patient with an asymptomatic tumor of 8 years evolution in the right posterior area of the hard palate. We performed surgical excision and a biopsy, which was reported as papillary cystadenoma lymphomatosum. During the post-operative examination carried out after 3 weeks, it was obser…

Characterization of a Human Carcinosarcoma Cell Line of the Ovary Established after in Vivo Change of Histologic Differentiation

2001

Abstract Objectives. Cell lines are valuable in vitro models for clinical and basic research. Most ovarian cancer cell lines described are serous cystadenocarcinomas or poorly differentiated adenocarcinomas. The establishment of ovarian cancer cell lines with rare histologic differentiation is especially of interest. We describe the establishment of a carcinosarcoma cell line of the ovary after in vivo selection. Methods. The cell line OV-MZ-22 was established from a solid tumor mass in the upper abdomen. At the time of establishment, the patient underwent secondary debulking and was pretreated with six cycles of cis -platinum/epirubicin/cyclophosphamide. Features of the cell line studied i…

Inflammatory papillary hyperplasia: a systematic review

2017

Introduction Inflammatory papillary hyperplasia (IPH) is a benign lesion of the palatal mucosa. It is usually found in denture-wearers but also has been reported in patients without a history of use of a maxillary prosthesis use. Objetives The aim of this study is to review the literature to assess the prevalence of denture stomatitis and inflammatory papillary hyperplasia and the etiological factors associated. Material and Methods A search was carried out in PubMed (January 2005 to October 2015) with the key words “inflammatory papillary hyperplasia”, “denture stomatitis”, “granular stomatitis” and “Newton’s type III” The inclusion criteria were studies including at least a sample of 50 a…

Correlation Between Ischemic Retinal Accidents and Radial Peripapillary Capillaries in the Optic Nerve Using Optical Coherence Tomographic Angiograph…

2017

Background: Perfusion of the optic nerve has been widely studied using fluorescein angiography (FAG), which is currently regarded as the criterion standard. However, FAG has adverse effects associated with intravenous contrast administration and is limited in its capacity to characterize and stratify the different vascular layers of the optic nerve and retina. The use of new imaging techniques, such as optical coherence tomographic angiography (Angio-OCT), is therefore important. Aim: A qualitative description is made of the vascular layers of the optic nerve and of how vascular events affect radial peripapillary capillaries (RPC). Two patients with central retinal artery occlusion (CRAO), …

Papillon- Lefevre Syndrome: Report of a case and its management

2012

Papillon-Lefèvre Syndrome (PLS) is a rare autosomal recessive disorder first described by two French physicians, Papillon and Lefèvre in 1924. The disorder is characterized by diffuse palmoplantar keratoderma and precocious aggressively progressing periodontitis, leading to the premature loss of deciduous and permanent teeth at a very young age. The cutaneous lesions are usually manifested simultaneously with the intra-oral presentations and include keratotic plaques on the palms and soles varying from mild psoriasiform scaly skin to overt hyperkeratosis. The etiopathogenesis of the syndrome is relatively obscure and immunologic, genetic or possible bacterial etiologies have been proposed. …
