Monomorphic Epstein-Barr virus (EBV)-associated large B-cell posttransplant lymphoproliferative disorder presenting as a tongue ulcer in a pancreatic transplant patient.

Posttransplant lymphoproliferative disorders are a group of lymphoid proliferations and lymphomas that develop as a consequence of immunosuppression in recipients of solid organ or bone marrow allografts. We describe an unusual oral presentation of posttransplant Epstein-Barr virus-associated diffuse large B-cell lymphoma in a 45-year-old woman after pancreatic transplant.

Atrophic glossitis from vitamin B12 deficiency: a case misdiagnosed as burning mouth disorder.

BACKGROUND: Glossodynia, or painful sensation of the tongue, can have a spectrum of etiologies, such as local infection, trauma, nerve damage, glossitis, or the enigmatic neuropathic pain syndrome, burning mouth disorder (BMD; also known as burning mouth syndrome). Careful history-taking, physical examination, and appropriate laboratory screening can differentiate these causes of glossodynia and direct further therapy. METHODS: A 73-year-old woman presented with several months of glossodynia having previously been diagnosed by her primary care physician with primary BMD. Subsequently, she consulted an otolaryngologist, who pursued further diagnostic evaluation. RESULTS: Examination revealed the presence of a beefy, red, smooth tongue, and further laboratory evaluation yielded a low serum vitamin B(12) level and macrocytosis. Three months of oral vitamin B(12) supplementation led to partial restoration of serum vitamin B(12) levels and a modest improvement in symptoms. Her final diagnoses were atrophic glossitis and glossodynia secondary to vitamin B(12) deficiency, most likely due to pernicious anemia. CONCLUSIONS: The results of this case have important clinical implications for the diagnostic evaluation and management of patients with glossodynia and apparent BMD. Pathogenic mechanisms of nutrient deficiency in atrophic glossitis are discussed.

Disabling pansclerotic morphea: clinical presentation in two adults.

Disabling pansclerotic morphea involves all layers of the skin, extending through the dermis and subcutaneous tissues to involve muscle, tendon, and bone. It is distinguished from generalized scleroderma by its lack of systemic involvement. Onset usually occurs before the age of 14 years. We describe adult-onset disabling pansclerotic morphea in two previously healthy young men. In both cases, the onset of disease was explosive, with rapid progression, widespread cutaneous involvement, and severe disablement caused by mutilating contracture deformities. Increased susceptibility of sclerodermatous tissue to recalcitrant ulceration and malignant transformation with development of nonmelanoma skin cancers was also observed. Treatment of this disease continues to present a therapeutic dilemma with only sporadic remission despite multimodality therapy.

Effectiveness of intravenous immunoglobulin therapy for skin disease other than toxic epidermal necrolysis: a retrospective review of Mayo Clinic experience.

OBJECTIVE: To examine retrospectively the use and effectiveness of intravenous immunoglobulin (IVIg) treatment of various skin diseases, primarily immunobullous disease. PATIENTS AND METHODS: We identified patients who had received IVIg therapy for skin disease between 1996 and 2003 at the Mayo Clinic in Rochester, Minn, Scottsdale, Ariz, and Jacksonville, Fla, and retrospectively reviewed their medical records. RESULTS: Eighteen patients were treated with IVIg for various skin diseases: immunobullous disease in 11 adults (pemphigus vulgaris [7 patients], bullous pemphigold [3], and cicatricial pemphigoid [1]); dermatomyositis (2); mixed connective tissue disease (1); chronic urticaria (1); scleromyxedema (1); leukocytoclastic vasculitis (1); and linear IgA bullous disease (1). Responses of patients by type of disease were as follows: pemphigus vulgaris, 1 partial response (PR) and 6 no response (NR); bullous pemphigoid, 1 complete response (CR) and 2 NR; cicatricial pemphigoid, 1 NR; dermatomyositis, 1 CR and 1 PR; mixed connective tissue disease, 1 CR; chronic urticaria, 1 CR; scleromyxedema, 1 CR; leukocytoclastic vasculitis, 1 PR; and linear IgA bullous disease, 1 CR. Six patients (33%) experienced CR, 3 (17%) had PR, and 9 (50%) had NR to IVIg therapy. All 9 nonresponders were adult patients with immunobullous disease. CONCLUSION: Although this was a retrospective study of a small cohort of a mixture of patients, the findings emphasize that our experience with IVIg treatment for skin disease, particularly immunobullous disease, is less favorable than that reported previously. Further studies are needed to verify the efficacy of IVIg for skin disease.

Response of oral lichen planus to topical tacrolimus in 37 patients.

BACKGROUND: Topical tacrolimus has been reported to be effective for the treatment of oral lichen planus. This article describes our experience with topical tacrolimus in patients treated for symptomatic oral lichen planus. OBSERVATIONS: A survey was mailed to 40 patients with symptomatic oral lichen planus treated with topical tacrolimus. Surveys were completed by 37 patients (93%) a mean of 1.3 years after initiation of treatment. Thirty-three (89%) of the 37 patients reported symptomatic improvement, and 31 (84%) reported partial to complete lesion clearance while using topical tacrolimus. On average, patients noted improvement in 1 month. Twelve patients (32%) reported adverse effects consistent with those reported previously (ie, burning, irritation, and tingling). Among the 28 patients still using the medication, 15 patients (54%) apply it at least once daily. Of the 9 patients who discontinued using the medication, 5 experienced recurrence. CONCLUSIONS: Topical tacrolimus is effective for the treatment of oral lichen planus. Most patients experienced symptomatic improvement in less than 1 month. However, the effect is temporary; when topical tacrolimus is discontinued, oral lichen planus may flare again.

Neutrophilic dermatosis of the hands: four new cases and review of the literature.

BACKGROUND: Isolated or predominantly hand involvement in Sweet's syndrome, pyoderma gangrenosum, or pustular vasculitis is a rare presentation in the spectrum of neutrophilic dermatoses and is often associated with an occult malignancy or other systemic inflammatory disorder. When these disorders occur on the hands, they are often clinically indistinguishable, but they can sometimes be separated histologically by the presence of papillary dermal edema (Sweet's syndrome), ulceration and necrosis (pyoderma gangrenosum), or vasculitis (pustular vasculitis). These distinctions may be arbitrary, however, and reflect differences in the temporal course of the disease and in the degree of inflammation at the time of biopsy. METHODS: We report four cases of neutrophilic dermatosis affecting the hands and a review of the literature for similar cases. RESULTS: Of the four patients presented, two had associated carcinomas and one had myelodysplasia in transition to leukemia. The cutaneous symptoms preceded the finding of an occult malignancy. Thirty-two reported cases of neutrophilic dermatoses presenting on the hands showed clinicopathologic features similar to those in our series. Taken together, the mean age at diagnosis was 60.5 years, and 58% of the patients were female. Twenty-five per cent (nine patients) also had myelodysplasia or leukemia, 14% (five patients) ulcerative colitis, 6% (two patients) carcinoma, 6% (two patients) Crohn's disease, and 6% (two patients) seropositive arthritis. CONCLUSIONS: These cases illustrate the importance of recognizing that neutrophilic dermatoses may present uniquely or predominantly on the hands. This presentation is distinctive, and prompt diagnosis may prevent unnecessary medical or surgical therapy and may lead to the earlier diagnosis and treatment of an associated malignancy or other systemic disorder.

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.

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.

Lipodermatosclerosis: review of cases evaluated at Mayo Clinic.

BACKGROUND: Lipodermatosclerosis describes bound-down, sclerotic skin involving the lower extremities. OBJECTIVE: Our purpose was to describe the demographic and clinical features of patients with lipodermatosclerosis. METHODS: This was a retrospective study of patients presenting to Mayo Clinic between 1976 and 1998 with a diagnosis of lipodermatosclerosis. RESULTS: Of 97 patients, 84 (87%) were women. Mean age was 62 years (range, 25-88 years). Mean body mass index was 34.3 (range, 17.8-71.5). Clinical signs were bilateral involvement in 44 patients (45%), induration localized to a discrete plaque in 49 (51%), erythema in 69 (71%), hyperpigmentation in 57 (59%), ulceration in 13 (13%), concomitant edema in 69 (71%), and varicosities in 55 (57%). Vascular studies performed on 72 patients showed abnormalities in 49: deep venous incompetence in 33 (67%), calf muscle pump abnormality in 19 (39%), abnormal pulsatility in 10 (20%), and obstruction in 1 (2%). CONCLUSION: Lipodermatosclerosis was associated with female sex, middle age, high body mass index, and venous abnormalities.

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.

Oral manifestations of sexually transmitted diseases.

Sexually transmitted diseases frequently affect the mucous membranes producing characteristic and potentially diagnostic lesions on the oral mucosa. This article reviews the classic route of transmission and the corresponding clinical presentation of several of the sexually transmitted viruses, including herpes virus types I and II, Epstein Barr virus, cytomegalovirus, human papilloma virus, molluscum contagiosum, as well as the human immunodeficiency virus. Bacterial infections such as syphilis, gonorrhea, as well as the fungus candida are reviewed under the umbrella of STDs with potential oral involvement encountered in the sexually active patient.

Oral and vulvar changes in pregnancy.

The endocrinologic, immunological, and vascular changes that occur during pregnancy are far-reaching. These systemic factors produce profound local impact on the physiology and pathology of the oral cavity, vagina, and vulva. Physiological changes can be expected and tolerable or of such severity that they are viewed as pathological. Existing disease can be exacerbated and dermatoses specific to pregnancy can erupt. Each of these conditions can pose potentially challenging treatment considerations.
