Eosinophilic Ulcer Of The Oral Mucosa
Eosinophilic ulcer of the oral mucosa (also known as traumatic eosinophilic granuloma) is a condition characterized by an ulcer with an indurated Friability ( ), the condition of being friable, describes the tendency of a solid substance to break into smaller pieces under duress or contact, especially by rubbing. The opposite of friable is indurate. Substances that are designated hazardous, ... and elevated border. The lesion might be tender, fast-growing and the patient often not be aware of any trauma in the area. Causes It is often associated with trauma. However, other causes are suspected, such as drugs, inherent predisposition, immune reaction, or lymphoproliferative disorder. Also called T.U.G.S.E. Found in parasitic infections of the alimentary canal. Symptoms prior to onset of oral ulcers are; constipation, diarrhea, abdomoninal gas and bloating, spastic hiccups, acid reflux and heartburn. Burning mouth syndrome appears as pre-onset symptom of ulcer manifestation. Uncotr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riga–Fede Disease
Riga–Fede disease (RFD) is a rare and benign mucosal condition, characterized by a tongue ulcer that is frequently brought on by traumatizing injuries sustained from repeatedly moving the tongue back and forth over the mandibular anterior incisors. Signs and symptoms Clinically, it typically manifests as a tongue-localized ulcer (60 percent of lesions), though it can also affect the lip, palate, gingiva, vestibular mucosa, and floor of the mouth. RFD may not cause any symptoms or may occasionally be accompanied by pain. Causes RFD is most frequently linked to the emergence of the natal-neonatal teeth in newborns or the primary lower incisor in older infants. Diagnosis Histopathologically speaking, RFD is characterized by mucosal areas that are ulcerated, granulation tissue present, and a mixed inflammatory infiltrate that is abundant in mast cells, macrophages, lymphocytes, and eosinophils Eosinophils, sometimes called eosinophiles or, less commonly, acidophils, are a variet ...

H&E Stain
Hematoxylin and eosin stain ( or haematoxylin and eosin stain or hematoxylin-eosin stain; often abbreviated as H&E stain or HE stain) is one of the principal tissue stains used in histology. It is the most widely used stain in medical diagnosis and is often the gold standard. For example, when a pathologist looks at a biopsy of a suspected cancer, the histological section is likely to be stained with H&E. H&E is the combination of two histological stains: hematoxylin and eosin. The hematoxylin stains cell nuclei a purplish blue, and eosin stains the extracellular matrix and cytoplasm pink, with other structures taking on different shades, hues, and combinations of these colors. Hence a pathologist can easily differentiate between the nuclear and cytoplasmic parts of a cell, and additionally, the overall patterns of coloration from the stain show the general layout and distribution of cells and provides a general overview of a tissue sample's structure. Thus, pattern recogniti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Induration
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions result ...

Eruptive Lingual Papillitis
Transient lingual papillitis are painful, hypertrophic, red and white lingual papillae on the tongue The tongue is a muscular organ in the mouth of a typical tetrapod. It manipulates food for mastication and swallowing as part of the digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste .... Cause Transient lingual papillitis can affect males and females as early as 3 years of age. In many cases, the cause is unknown. Some dental professionals believe the inflammation is due to chronic irritation from teeth, fillings, or dental appliances. Stress, poor nutrition, smoking, and alcohol use may also be initiating factors. References Tongue Conditions of the mucous membranes Oral mucosal pathology Tongue disorders {{Med-stub ...

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...

Eosinophilic Cutaneous Conditions
Eosinophilic (Greek suffix -phil-, meaning ''loves eosin'') is the staining of tissues, cells, or organelles after they have been washed with eosin, a dye. Eosin is an acidic dye for staining cell cytoplasm, collagen, and muscle fibers. ''Eosinophilic'' describes the appearance of cells and structures seen in histological sections that take up the staining dye eosin. Such eosinophilic structures are, in general, composed of protein. Eosin is usually combined with a stain called hematoxylin to produce a hematoxylin- and eosin-stained section (also called an H&E stain, HE or H+E section). It is the most widely used histological stain for a medical diagnosis. When a pathologist examines a biopsy of a suspected cancer, they will stain the biopsy with H&E. Some structures seen inside cells are described as being eosinophilic; for example, Lewy and Mallory bodies. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
