Complex aphthosis.

Clearly, complex aphthosis alone does not constitute BD. Furthermore, the patient with complex aphthosis should be evaluated for associated conditions or diseases, some of which are "correctable causes" of RAS. The oral lesions of BD are aphthous in nature and are best classified as complex aphthosis. While some patients with complex aphthosis will develop BD, some will remain as sufferers of complex aphthosis for years until a cause is identified or the disease enters a spontaneous or therapeutically induced remission. Complex aphthosis is the major pseudo-Behçet's disease encountered in a referral practice.

Viral diseases of the oral mucosa.

A wide variety of both DNA and RNA viruses affect the oral cavity. When considered in conjunction with cutaneous features, careful examination of the oral mucosa and oropharynx aids the clinician in making a diagnosis. Examination of the oral cavity should be incorporated as a regular component of the dermatologic examination because diagnostic clues are readily available to assist in the evaluation of infectious processes.

Glossitis and other tongue disorders.

Patients frequently present complaining of tongue abnormalities. Knowledge of normal tongue anaomy an d architecture enable the clinician t odifferentiate variations of normal from abnormal conditions. Many tongue conditions are benign and. require reassurance and explanation, with little to no treatment. Others can signify systemic disorders. Examination of the tongue is an integral part of a complete physical examination. Recognizing the disorders of the tongue that are benign and do not require treatment or further evaluation prevents unnecessary testing for the patient. Careful evaluation of the tongue may provide valuable clues to a systemic disorder.

Erosive oral lichen planus with genital lesions: the vulvovaginal-gingival syndrome and the peno-gingival syndrome.

Lichen planus is an inflammatory mucocutaneous disorder that may involve mucosal surfaces, such as the oral, genital, and other mucosae, and the skin including the scalp and the nails. Ocular, esophageal, bladder, nasal, laryngeal, otic, gastric, and anal involvement may occur. This article describes patients with the unique chronic orogenital variant of erosive oral lichen planus in both women and men. Although treatment of genital Lichen planus is quite challenging, therapeutic benefit in this painful, protracted condition can be obtained.

Pseudo-Behçet's disease.

The conditions of complex aphthosis, EM, MMP, and the VVG variant of erosive oral LP may be confused by clinicians who refer patients for diagnosis and management of BD (Table 8). The mucocutaneous presentations or the presence of complex aphthosis, the hallmark of BD, can be confusing and lead to the referral of the patient for a diagnosis of BD. The astute clinician evaluating patients for BD considers pseudo-BD in the differential diagnosis of the mucocutaneous manifestations of BD.

Oral manifestations of erythema multiforme.

Erythema multiforme is a reactive mucocutaneous disorder in a disease spectrum that comprises a self-limited, mild, exanthematic, cutaneous variant with minimal oral involvement (EM minor) to a progressive, fulminating, severe variant with extensive mucocutaneous epithelial necrosis (SJS and TEN). Significant differences exist among EM minor, EM major, SJS, and TEN with regards to severity and clinical expression; however, all variants share two common features: typical or less typical cutaneous target lesions and satellite-cell or more widespread necrosis of the epithelium. These features are considered to be sequelae of a cytotoxic immunologic attack on keratinocytes expressing non-self-antigens. These antigens are primarily microbial (viruses) or drugs and in rare instances histocompatibility antigens [5]. Although the precise pathogenesis is unknown, there is a tendency to consider EM both minor and major as part of one spectrum that is most often triggered by viral infections, and SJS and TEN as a separate one most often elicited by drugs with EM major and SJS representing a bridge in the continuum of EM. The oral manifestations of the spectrum of EM range from tender superficial erythematous and hyperkeratotic plaques to painful deep hemorrhagic bullae and erosions. Other mucosal surfaces including ocular, nasal, pharyngeal, laryngeal, upper respiratory, and anogenital may be involved. Scarring sequelae from ocular and pharyngeal involvement cause morbidity. The oral EM variant is an underrecognized form of EM. Most patients have chronic or recurrent oral lesions only, but one third have oral and lip lesions and one quarter have oral, lip, and skin lesions. This variant is a reaction pattern similar to EM minor, EM major, SJS, and TEN. The diagnosis of oral EM is one of exclusion. Careful clinical evaluation for other chronic mucocutaneous diseases, such as pemphigus, paraneoplastic pemphigus, mucous membrane pemphigoid, and lichen planus, is a necessary component of the diagnosis. The value of a biopsy specimen studied by both routine histopathologic and immunopathologic methods is fundamental to excluding the other causes for this variant of EM.

Burning mouth syndrome.

Burning mouth syndrome is the occurrence of oral pain in a patient with a normal oral mucosal examination. It can be caused by both organic and psychologic or psychiatric factors, which can be broken down into local, systemic. psychologic or psychiatric, and idiopathic causes. The most frequently associated conditions are psychiatric (depression, anxiety, or cancerphobia); xerostomia; nutritional deficiency; allergic contact dermatitis; candidiasis; denture-related pain: and parafunctional behavior. Multiple different factors contributing to the oral pain are common, and a systematic approach to the evaluation is important. Identification of correctable causes of BMS should be emphasized and psychiatric causes should not be invoked without thorough evaluation of the patient. A directed history and careful oral examination must be completed to exclude local diseases and identify clues to potential causes. Assessment of medications, psychiatric history and background, and selected laboratory and patch tests may help identify the etiologies of these symptoms. Treatment should be tailored to each patient and may best be managed in a multidisciplinary approach with input from dermatologists, dentists, psychiatrists. otorhinolaryngologists, and primary care providers. A thoughtful and structured evaluation of the patient with BMS has been associated with improvement in about 70% of patients. The remaining patients may benefit from empiric therapy with a chronic pain protocol and continued supportive interactions.

Acute oral ulcers.

In general, a detailed history and examination of the patient provides sufficient information for diagnosis. The pattern, frequency, and natural history of ulcer episodes are helpful. The presence or absence of associated features and the site of oral involvement guides most physicians accurately in the diagnosis. Additional investigations, including blood tests, and occasionally the use of oral cultures or biopsy, are needed to make a definitive diagnosis. A multispecialty approach is often necessary to evaluate patients with other systemic features. Most acute oral ulcers heal spontaneously without specific therapy being necessary, but an understanding of the cause of the ulcer is reassuring to the patient and guides the clinician in management to prevent recurrent episodes of oral ulceration, or chronicity of ulcers.

Oral psoriasis.

It is strange that the existence of oral psoriasis seems so rare. Other papulosquamous disorders, such as lichen planus, are frequently associated with oral manifestations, yet oral psoriasis is rare given the prevalence of cutaneous disease. One explanation is that oral lesions are asymptomatic and do not come to the clinician's attention. Other explanations, however, are necessary. Epithelial turnover time is significantly increased in psoriatic plaques and may be as rapid as 3 to 7 days, whereas normal epithelial turnover is 28 days. Some have suggested that this abnormally increased turnover time in psoriasis approximates that of the normal regenerative time of the oral epithelium, and this possibility may account for the apparent lack of changes in the oral mucosa of patients with psoriasis [1]. It is also possible that oral lesions of psoriasis are altered both clinically and histologically by other factors within the oral microenvironment and are not recogized. Although controversy has appeared in the literature about whether lesions of oral psoriasis exist, there is sufficient evidence that a subset of patients have oral lesions in association with skin disease. This occurrence is more common in patients with the severe forms of psoriasis, such as generalized pustular psoriasis. The diagnosis of oral psoriasis should be based on good clinical and histologic evidence, and, in general, the clinical course of the oral lesions should parallel that of the skin disease. Exclusion of other causes is important, particularly if cutaneous lesions are absent and a diagnosis of isolated oral psoriasis is entertained. Because neither the clinical nor the histologic changes are absolutely specific for psoriasis, the patient requires holistic evaluation. That being said, in day-to-day practice it is most likely not practical to obtain a biopsy of asymptomatic oral lesions for definitive histologic or immunofluorescence studies. The clinician, however, must have a high degree of awareness and pay close attention to the oral mucosa in patients with psoriasis. A thorough examination is imperative, because asymptomatic oral lesions may be found more frequently in patients with psoriasis if clinicians habitually check mucous membranes during the generalized skin examination. Conversely, in patients with troublesome oral lesions, a cutaneous examination that reveals subtle changes suggestive of psoriasis may provide clues to the oral diagnosis. A detailed history remains the cornerstone of diagnosis, because a family history of psoriasis or a history of psoriasis now in remission may guide physicians when they note oral lesions.

Pediatric oral medicine.

A thorough examination of the oral mucosa can provide helpful clues toward making a diagnosis in a number of developmental, neoplastic, inflammatory, and infectious conditions. A number of oral lesions seen in infants and children are benign and of no medical significance. In these instances, the ability of the physician to confidently identify the diagnosis, and reassure parents that a lesion is not worrisome, carries significant value. Likewise, the ability to recognize an underlying systemic illness or genetic disease based on an oral examination can also be of tremendous value, particularly when oral involvement is the presenting feature.

Oral manifestations of genodermatoses.

Many genodermatoses have distinct oral features that may help identify or confirm a genetic diagnosis. Oral features of the disorders described here are summarized in Table 1. These conditions provide clear examples of rapid progress in the field of genetic technology relevant to patient care. Less than a decade ago, the exact genetic locus of most of these disorders was unknown. Today, for many of these disorders, the exact location of the disease-causing mutation is known and clinical genetic testing is available for patients. This information has impact not only for genetic counseling and anticipatory medical care, but also provides insight into the mechanisms of disease. How this rapid progress will impact care, and ultimately treatment of patients, remains to be seen.

The first international consensus on mucous membrane pemphigoid: definition, diagnostic criteria, pathogenic factors, medical treatment, and prognostic indicators.

OBJECTIVE: We aimed to develop consensus-based recommendations for streamlining medical communication among various health care professionals, to improve accuracy of diagnosis and treatment, and to facilitate future investigations for mucous membrane pemphigoid. PARTICIPANTS: Because of the highly specific nature of this group of diseases, the 26 invited participants included either international scholars in the field of mucous membrane pemphigoid or experts in cutaneous pharmacology representing the 3 medical disciplines ophthalmology, oral medicine, and dermatology. EVIDENCE: The first author (L.S.C.) conducted a literature search. Based on the information obtained, international experts who had contributed to the literature in the clinical care, diagnosis, and laboratory investigation for mucous membrane pemphigoid were invited to participate in a consensus meeting aimed at developing a consensus statement. CONSENSUS PROCESS: A consensus meeting was convened and conducted on May 10, 1999, in Chicago, Ill, to discuss the relevant issues. The first author drafted the statement based on the consensus developed at the meeting and the participants' written comments. The draft was submitted to all participants for 3 separate rounds of review, and disagreements were reconciled based on literature evidence. The third and final statement incorporated all relevant evidence obtained in the literature search and the consensus developed by the participants. The final statement was approved and endorsed by all 26 participants. CONCLUSIONS: Specific consensus-based recommendations were made regarding the definition, diagnostic criteria, pathogenic factors, medical treatment, and prognostic indicators for mucous membrane pemphigoid. A system of standard reporting for these patients was proposed to facilitate a uniform data collection.

Topical tacrolimus in the treatment of symptomatic oral lichen planus: a series of 13 patients.

BACKGROUND: Oral lichen planus (OLP) is a relatively common, chronic inflammatory condition, which frequently presents with symptoms of pain and irritation. OLP is often difficult to manage. Therefore there is a need for more effective and safer therapies for symptomatic OLP. OBJECTIVE: Our purpose was to determine the effectiveness of topical tacrolimus as therapy for symptomatic OLP. METHODS: A retrospective review was performed of 13 patients with symptomatic OLP treated with topical tacrolimus between September 1999 and September 2000. RESULTS: Eleven of the 13 patients reported definite symptomatic response to treatment and 2 had no response. Eight patients had a partial response, whereas 3 patients had a complete response with respect to lesion clearance. Seven of the responding patients had no flares with continued treatment. The other 4 patients noted flares soon after stopping the treatment. Side effects were rare and minor. CONCLUSIONS: In this retrospective case series of 13 patients, topical tacrolimus was well tolerated and appeared to be an effective therapy to control symptoms and clear lesions of OLP.

Pyostomatitis vegetans as an early sign of reactivation of Crohn's disease: a case report.

BACKGROUND: The structures and lining of the oral cavity are an accessible mirror reflecting the health of an individual. They may play an important role in detecting and monitoring systemic diseases. Certain conditions that primarily affect other regions of the body may cause signs and symptoms in the mouth, either as the initial presenting symptom or in conjunction with other systemic manifestations. METHODS: Pyostomatitis vegetans, which occurred in a patient with a history of Crohn's disease, was diagnosed as an early sign of disease reactivation. RESULTS: The patient was treated with a topical fluorinated corticosteroid gel, which led to the improvement of the oral lesions. However, the oral lesions continued to recur over a period of several months until the underlying inflammatory bowel disease came under control. CONCLUSIONS: This report emphasizes the relationship of pyostomatitis vegetans to Inflammatory bowel disease and the importance of the oral lesions as initial presenting signs of systemic disease or activity.
