Angina Bullosa Haemorrhagica
Angina bullosa haemorrhagica is a condition of the mucous membranes characterized by the sudden appearance of one or more blood blisters within the oral cavity. The lesions, which may be caused by mild trauma to the mouth tissues such as hot foods, typically rupture quickly and heal without scarring or further discomfort. The condition is not serious except in rare cases where a large bulla that does not rupture spontaneously may cause airway obstruction. The blisters usually affect the palate or oropharynx, and are often long lived to the extent that patients burst them for symptomatic relief.Edward W. Odell, 2010. Clinical Problem Solving in Dentistry Diagnosis The condition is diagnosed on the basis of exclusion of other conditions and the typical presentation, particularly the constant presence of blood as the blister fluid. Angina bullosa haemorrhagica does not cause desquamative gingivitis. Treatment Treatment includes steroid gel and analgesics (anesthetic suspension). ...

Mucous Membrane
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and reproductive ...

Desquamative Gingivitis
Desquamative gingivitis is an erythematous (red), desquamatous (shedding) and ulcerated appearance of the gums. It is a descriptive term and can be caused by several different disorders. Signs and symptoms Desquamative gingivitis involves lesions of the free and attached gingiva. Unlike plaque-induced inflammation of the gums (normal marginal gingivitis), desquamative gingivitis extends beyond the marginal gingiva, involving the full width of the gingiva and sometimes the alveolar mucosa. The term "full width gingivitis" usually refers to the oral lesions of orofacial granulomatosis however. The color is another dissimilarity between typical marginal gingivitis and desquamative gingivitis, in the latter it is dusky red. Plasma cell gingivitis is another form of gingivitis which affects both the attached and free gingiva. Cause Caused by various autoimmune diseases as well as allergies. Erosive lichen planus, mucous membrane pemphigoid, pemphigus vulgaris, erythema exsudativum m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mucocele
A mucocele is a distension of a hollow organ or cavity because of mucus buildup. By location Oral Oral mucocele is the most common benign lesion of the salivary glands generally conceded to be of traumatic origin. It is characterized by the pooling of mucus in a cavity due to the rupture of salivary ducts or acini. It can occur in the lower lip, palate, cheeks, tongue and the floor of the mouth. Appendix Appendiceal mucocele is found in 0.3 to 0.7% of the appendectomies.Creative Commons Attribution 4.0 Internationallicense It is characterized by the dilation of the organ lumen with mucus accumulation. Appendix mucocele may come as a consequence of obstructive or inflammatory processes, cystadenomas or cystadenocarcinomas. Its main complication is pseudomyxoma peritonei.

Acute Necrotizing Ulcerative Gingivitis
Acute necrotizing ulcerative gingivitis (ANUG) is a common, non-contagious infection of the gums with sudden onset. The main features are painful, bleeding gums, and ulceration of inter-dental papillae (the sections of gum between adjacent teeth). This disease, along with necrotizing (ulcerative) periodontitis (NP or NUP) is classified as a necrotizing periodontal disease, one of the seven general types of gum disease caused by inflammation of the gums (periodontitis). The often severe gum pain that characterizes ANUG distinguishes it from the more common chronic periodontitis which is rarely painful. If ANUG is improperly treated or neglected, it may become chronic and/or recurrent. The causative organisms are mostly anaerobic bacteria, particularly Fusobacteriota and spirochete species. Predisposing factors include poor oral hygiene, smoking, poor nutrition, psychological stress, and a weakened immune system. When the attachments of the teeth to the bone are involved, the ...

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 meso ...
