Usage subject to terms and conditions of license 44 Red Lesions Traumatic Erythema Definition and etiology Traumatic erythema occurs when a traumatic effect results in hemorrhage within the oral tissues. Clinical features Traumatic erythema can present either as an ecchy- mosis or as a hematoma. Clinically, it appears as an irregular, usually flat, area with a bright or deep red color (Fig. Differential diagnosis Hematomas due to anticoagulants, thrombocy- topenia, thrombasthenia. Thermal Burn Definition and etiology Thermal burns to the oral mucosa are fairly common, usually due to contact with very hot foods, liquids, or hot metal objects. Clinical features Clinically, the condition appears as a red, painful erythema that may undergo desquamation, leaving erosions (Fig. Differential diagnosis Chemical burn, traumatic lesions, herpes sim- plex, aphthous ulcers, drug reactions.

Differential diagnosis Mycositis due to chemotherapy, graft-versus- host disease, erythema multiforme, herpetic stomatitis, lichen planus. Cessation of the radiation treatment, B-com- plex vitamins, and sometimes low doses of steroids are indicated. Etiology Orogenital sex and the negative pressure or repeated “irrita- tion” applied during fellatio. Clinical features The lesions present as petechiae, erythema, or ecchy- moses usually at the junction of the soft and hard palate (Fig. They disappear spontaneously within a week, and the diagnosis is made on the basis of the history and the clinical features.

Differential diagnosis Psoriasis, Reiter syndrome, plasma-cell stoma- titis, mucous patches of secondary syphilis, candidiasis. Median Rhomboid Glossitis Definition Median rhomboid glossitis is a rare condition that occurs exclusively on the dorsumof the tongue. Clinical features It presents as a well-demarcated erythematous rhomboid area along the midline of the dorsum of the tongue, immedi- ately anterior to the circumvallate papillae (Fig. Differential diagnosis Candidiasis, lymphangioma, geographic tongue, syphilis, hemangioma, non-Hodgkin lymphoma. Usage subject to terms and conditions of license 50 Red Lesions Denture Stomatitis Definition Denture stomatitis, or denture sore mouth, is a frequent condition in patients who wear dentures continuously for extended times.

The clinical features are identical to erythroplakia, erythematous candidiasis, or contact reactions to dental materials. Usage subject to terms and conditions of license 54 Red Lesions Erythroplakia Definition Erythroplakia, or Queyrat erythroplasia, is a premalignant lesion frequently occurring on the glans penis, and rarely on the oral mucosa. It is defined as a red, nonspecific patch or plaque that cannot be classified clinically and pathologically under any other disease. Clinical features It appears as a usually asymptomatic, fiery red, well- demarcated plaque, with a smooth and velvety surface (Figs. The floor of the mouth, retromolar area, soft palate, and tongue are the most common sites of involvement. Over 91% of erythroplakias histo- logically demonstrate severe dysplasia, carcinoma in situ, or early in- vasive squamous-cell carcinoma at the time of diagnosis. Differential diagnosis Erythematous candidiasis, lichen planus, dis- coid lupus erythematous, early squamous-cell carcinoma, local irritation. Usage subject to terms and conditions of license 56 Red Lesions Plasma-Cell Gingivitis Definition Plasma-cell gingivitis is a rare and unique gingival disorder, characterized histopathologically by a dense chronic inflammatory in- filtration of the lamina propria, mainly of plasma cells. Reactions to local allergens, chronic infections, and plasma-cell dyscrasias have been considered as possible causes. Thegingivitismay be localized or widespread, and is frequently accompanied by a burning sensation. Laboratory tests Histopathological and histochemical examination, immunoelectrophoresis. Differential diagnosis Desquamative gingivitis, psoriasis, candidiasis, soft-tissue plasmacytoma, erythroplakia, granulomatous gingivitis.

Etiology Foreign body reaction, local bacterial or fungal infection, re- actions to food additives and systemic granulomatous disorders (Crohn disease, sarcoidosis, Melkersson–Rosenthal syndrome, Wegener granu- lomatosis) may be the cause. Clinical features Granulomatous gingivitis presents as a diffuse ery- thematous and slightly edematous area of the free and attached gingiva, and of the interdental papillae (Figs. In cases of systemic granulomatous disease, other areas of the mouth may be involved. The clinical diagnosis should be confirmed by a biopsy and histopathological examination. Differential diagnosis Plaque-related chronic gingivitis, desquamative gingivitis, linear gingiva erythema, trauma, plasma-cell gingivitis, drug reactions, candidiasis, erythroplakia, non-Hodgkin lymphoma, leukemia, amyloidosis, orofacial granulomatosis. In case of reaction to foreign material, conservative surgical excision is suggested. Usage subject to terms and conditions of license 60 Red Lesions Desquamative Gingivitis Definition Desquamative gingivitis is a clinical descriptive term used for nonspecific gingival manifestation of several chronic mucocutaneous diseases. Cicatricial pemphigoid and lichen planus are the most common diseases related to desquamative gingivitis. Less frequently, bullous pemphigoid, pemphigus, linear IgA disease, epidermolysis bullosa ac- quisita, chronic ulcerative stomatitis, discoid lupus erythematosus, and psoriasis may be the underlying disease entity.

Anteriorly the trachea is covered by skin, superficial and deep fascia, sternohyoid and sternothyroid muscles. Tracheostomy may be needed to relieve lobes enclosed in the pretracheal fascia, respiratory obstruction which may be due carotid sheath and other greater vessels and to the following: nerves of the neck. Inflammatory diseases of the upper on the oesophagus and the recurrent laryngeal respiratory tract like acute laryngo- nerves ascend on each side between the tracheobronchitis, laryngeal diphtheria trachea and the oesophagus. Trauma such as laryngeal injury, Tracheostomy maxillary and mandibular fractures, This is a procedure wherein an opening is inhalation of irritant fumes or corrosive made in the anterior tracheal wall which is poisoning causing laryngeal oedema. Tracheostomy may be needed to prevent aspiration of fluids, pus or blood from the trachea. Diseases like bulbar paralysis leads to pharyngeal paralysis and incom- petence of the laryngeal sphincteric mechanism which leads to overspill of oral secretions into the larynx. Hence tracheostomy is required to separate the lower respiratory tract from the pharynx. Tracheostomy is indicated in certain diseases which lead to retention of secretions in the lower respiratory tract. These conditions include bron- operation is done when the laryngeal chiectasis, lung abscess, chronic bronchitis, obstruction is acute and demanding an etc. Under such circumstances various conditions like head injury and the patient’s head and neck are extended diabetic coma for proper suction of and the trachea palpated.

There are chances of damage to the cricoid cartilage and subsequent subglottic stenosis. Midtracheostomy is the ideal procedure where the opening is made behind the isthmus on the third ring. Complications of Tracheostomy Various complications may arise during or after the operation. Complications that can arise during surgery include haemorrhage mainly due to trauma to the thyroid veins. Surgical emphysema of the neck and chest midline to expose the thyroid isthmus and may occur as the air may leak into the trachea.
