Immunohistochemical expression and distribution of orexin, orphanin and leptin in the major salivary glands of some mammals

2012

Abstract: The aim of the study was to assess the involvement of apoptotic factors, cytokeratins and metalloproteinase- 9 in the histogenesis of both Epithelialized Gingival Lesions (EGL) and Periapical Lesions (PAL). 55 consecutive patients, 30 with PAL and 25 with EGL, were selected for the study after clinical and radiological examinations. The PAL patients had severe periapical lesions and tooth decay with exposure of the pulp chamber. All PAL and EGL biopsies were surgically extracted, fixed in 10% buffered formalin, and processed for routine light microscopy. Ten biopsies of each category were processed for immunohistochemistry (IHC). Serial paraffin sections were stained by IHC with a…

Adenomatoid odontogenic tumor with impacted mandibular canine: a case report

2011

The Adenomatoid Odontogenic Tumor (AOT) is a rare, slow growing, benign, odontogenic epithelial tumor with characteristic clinical and histological features; which usually arise in the second or third decade. It is a tumor composed of odontogenic epithelium in a variety of histoarchitectural patterns which are embedded in a mature connective tissue stroma. It is mostly encountered in young patients with a greater predilection for females. Maxilla is the predilection site of occurrence, most commonly associated with an unerupted maxillary canine. It presents as a symptom-free lesion and is frequently discovered during routine radiographic examination. This case report describes an unusual ca…

Central Odontogenic Fibroma combined with Central Giant Cell lesion of the mandible. Immunohistochemical profile.

2011

Central Odontogenic Fibroma is a benign neoplasm of mesenchymal origin that makes up less than 5% of odontogenic tumors. There is a variation of this lesion that includes a zone of giant cells. This neoplasm is characterized by fibroblast proliferation, a component of apparently inactive odontogenic epithelium within a mature connective tissue stroma and multinucleated osteoclast-like giant cells. Clinically, it manifests as a slow-growing central lesion, which causes painless cortical expansion and may occasionally cause the displacement of adjacent dental organs or resorption. We present a new case of this combined lesion that was revealed radiographically as a well-defined radiolucent ar…
