Orofacial Manifestations in a Middle-Aged Woman with Cowden Syndrome: A Case Image.

A 56-year-old Brazilian woman sought dental care, presenting with multiple asymptomatic papillomatous lesions with a coalescent pattern and intermingled cobblestone-like clefts along the alveolar ridge and marginal and attached gingivae. Multiple whitish papules were also observed on the face, neck, and limbs. Incisional biopsies of these lesions were performed. Microscopically, the skin lesion revealed epithelial clear cells and intraepithelial keratinization with areas of orthokeratosis, while the gingival lesions showed a parakeratinized stratified squamous epithelium with collagenous connective tissue. These features were consistent with those of a trichilemmoma and fibroepithelial hyperplasia, respectively. This article illustrates a case of Cowden syndrome (CS), a rare multisystem genetic condition in which both cutaneous and mucosal tissues were affected. Fewer than 40 cases of CS with oral involvement affecting middle-aged adults have been documented hitherto.

Treatment of oral chronic graft-versus-host disease: a retrospective cohort study.

OBJECTIVE: The aim of this study was to evaluate patients with complete response of oral chronic graft-versus-host disease to immunosuppressive treatment. METHODS: A total of 29 patients submitted to allogeneic hematopoietic stem cell transplantation, with oral chronic graft-versus-host disease, were enrolled in this retrospective study, from September 2012 to February 2018. Patients were treated with combined topical dexamethasone solution and topical tacrolimus ointment, combined topical dexamethasone and topical tacrolimus, systemic immunosuppressive medication, and topical dexamethasone only. RESULTS: The mean time of complete response of lichenoid lesions, erythema, and ulcers using dexamethasone and systemic immunosuppressive medication was of 105, 42 and 42 days, respectively (p=0.013).When we associated dexamethasone, tacrolimus and systemic immunosuppressive medication, the mean time of complete response of lichenoid lesions, erythema and ulcers was of 91,84 and 77 days (p=0.011). When dexamethasone was used alone, the mean time of complete response of lichenoid lesions, erythema and ulcers was 182, 140, 21 days, respectively (p=0.042). CONCLUSION: Our study shows that lichenoid lesions require more time to heal. Notably, lichenoid lesions tend to respond better to dexamethasone combined with tacrolimus and systemic immunosuppressive medication, whereas erythema and ulcers respond better to dexamethasone combined with systemic immunosuppressive medication and dexamethasone only, respectively.

RESUMO Objetivo Avaliar os pacientes com resposta completa da doença do enxerto contra hospedeiro crônica oral ao tratamento com imunossupressor. Métodos Vinte e nove pacientes submetidos ao transplante alogênico de células tronco hematopoiéticas, com doença do enxerto contra hospedeiro crônica oral, foram incluídos neste estudo retrospectivo, de setembro de 2012 a fevereiro de 2018. Os pacientes foram tratados com dexametasona para bochecho associada ao tacrolimo pomada, dexametasona para bochecho associada ao tacrolimo tópico, tratamento imunossupressor sistêmico, e dexametasona tópica apenas. Resultados O tempo médio para resposta completa das lesões liquenoides, eritema e ulcerações usando dexametasona e imunossupressor sistêmico foi de 105, 42 e 42 dias, respectivamente (p=0,013). Quando a dexametasona estava associada ao tacrolimo e a medicação imunossupressora sistêmica, o tempo médio para resposta completa das lesões liquenóides, eritema e ulcerações foi de 91, 84 e 77 dias (p=0,011). Quando foi utilizada apenas dexametasona, o tempo médio para resposta completa das lesões liquenoides, eritema e ulcerações foi de 182, 140 e 21 dias, respectivamente (p=0,042). Conclusão Nosso estudo mostra que as lesões liquenoides requerem mais tempo para cicatrização completa. É notável que as lesões liquenoides tendem a responder melhor ao tratamento da dexametasona combinada com o tacrolimo e o imunossupressor sistêmico. Já o eritema e as ulcerações respondem melhor à dexametasona combinada com medicação imunossupressora sistêmica, e dexametasona apenas, respectivamente.
