Anal cancer screening in a high-risk behavior group: A local picture / Rastreamento de câncer anal em um grupo de comportamento de alto risco: uma imagem local

ABSTRACT Study objectives To perform anal lesion and anal cancer screening in men living with HIV/AIDS. Methods This is a descriptive, observational, cross-sectional study. Data were obtained from the Specialized Assistance Service (SAE) in Divinópolis, Minas Gerais. A sociodemographic, epidemiological, and sexual behavior questionnaire was applied; material was collected for cytology, high-resolution anoscopy (AAR) was performed, and an acceptability questionnaire applied. Main results Of the 50 men living with HIV/AIDS invited to participate in this study, 6% were excluded because they were illiterate, 40% refused to participate, and 54% participated in the survey. Among these, all answered the self-administered questionnaire. However, ten (37.0%) underwent proctological examination and anal cytology. Of these, two did not respond to the acceptability questionnaire. No anal lesions were identified during AAR and no biopsy was required. A 10% change in anal cytology was found. Conclusions Through the study it was possible to construct a flow of referrals from the SAE to the UFSJ Coloproctology outpatient clinic. Moreover, the existence of internal stigmas on the part of the participants regarding the proctological examination and the lack of information about anal cancer screening are challenges to be overcome.

RESUMO Objetivos do estudo Realizar o rastreamento de lesões anais e câncer anal em homens vivendo com HIV/AIDS. Métodos Trata-se de estudo descritivo observacional transversal, cujos dados foram obtidos no Serviço de Assistência Especializada (SAE) em Divinópolis, Minas Gerais. Foi aplicado questionário sociodemográfico, epidemiológico e de comportamento sexual; realizada coleta de material para citologia, Anuscopia de Alta Resolução (AAR) e aplicado questionário de aceitabilidade do exame. Principais resultados Dos 50 homens vivendo com HIV/AIDS convidados a participar do presente estudo, 6% foram excluídos por serem analfabetos, 40% se recusaram a participar e 54% participaram da pesquisa. Entre estes, todos responderam o questionário autoaplicado. Entretanto, 10 (37.0%) realizaram o exame proctológico e a citologia anal. Desses, dois não responderam ao questionário de aceitabilidade. Não foram identificadas lesões anais durante a AAR, não sendo necessária a realização de biópsia. Foi encontrado 10% de alteração à citologia anal. Conclusões Por meio do estudo foi possível construir um fluxo de encaminhamentos do SAE para o ambulatório de Coloproctologia da UFSJ. Ademais, a existência de estigmas internos por parte dos participantes no que concerne à realização do exame proctológico e a falta de informação a respeito do rastreamento do câncer anal são desafios a serem vencidos.

Oral squamous papilloma: a view under clinical, fluorescence and histopathological aspects.

Oral squamous papilloma is a benign tumor whose pathogenesis has been associated with human papillomavirus infection. Thus, it is noteworthy that human papillomavirus infection is one of the risk factors associated with the development of cervical, anogenital, pharynx, larynx and oral cavity carcinomas. Oral squamous papilloma can affect any region of the oral cavity, and transmission of human papillomavirus can occur by direct contact, sexual intercourse or from mother to child during delivery. The diagnosis is clinical and histopathological, with surgical removal representing the treatment of choice. Recently, widefield optical fluorescence has been used as a complementary examination to the conventional clinical examination in the screening of oral pathological lesions and for the delimitation of surgical margins. We report a case of oral squamous papilloma with its clinical, histopathological features and, in addition, from the perspective of wide field optical fluorescence.

RESUMO O papiloma escamoso oral é um tumor benigno, cuja patogênese tem sido associada à infecção pelo papilomavírus humano. A infecção pelo papilomavírus humano é um dos fatores de risco associado ao desenvolvimento dos carcinomas cervicais, anogenitais, faríngeos, laríngeos e da cavidade oral. O papiloma escamoso oral pode acometer qualquer região da cavidade oral, e a transmissão do papilomavírus humano ocorre por contato direto, relação sexual ou de mãe para filho durante o parto. O diagnóstico é clínico e histopatológico, e a remoção cirúrgica representa o tratamento de escolha. Recentemente, a fluorescência óptica de campo amplo tem sido empregada como exame complementar ao exame clínico convencional, no rastreio de lesões patológicas orais e para delimitação de margens cirúrgicas. Relatamos um caso de papiloma escamoso oral com suas características clínicas e histopatológicas, sob a perspectiva da fluorescência óptica de campo amplo.

Juvenile-onset recurrent respiratory papillomatosis with pulmonary involvement and carcinomatous transformation

Papilloma associated with recurrent respiratory papillomatosis (RRP), caused by human papilloma virus (HPV) infection types 6 and 11, is the most common benign neoplasm of the larynx. The clinical features of RRP vary widely from mild to aggressive forms. RRP in children is known as juvenile-onset recurrent respiratory papillomatosis (JORRP). Its outcome may be poor or even fatal due to the high rate of recurrence and eventual spread to the entire respiratory tract. Pulmonary invasion is reported to occur in 3.3% of patients with RRP, and malignant transformation in 0.5% of patients. We report the case of a 39-year-old female patient with a diagnosis of JORRP from the age of 3 years, with extensive bilateral pulmonary involvement and malignant transformation. Analysis of the papilloma and carcinomatous tissues revealed the presence of HPV type 11, which is associated with rapid and aggressive progression. We discussed the case on the basis of a literature review on pulmonary invasion, malignant transformation, and HPV 11 aggressiveness.

Mediastinal teratoma with malignant degeneration.

Here, we report the case of a patient with a slowly-progressing anterior mediastinal teratoma submitted to surgical resection. The anatomopathological examination of the sample revealed malignant degeneration to carcinoid tumor. Such evolution is very rare, and we have found only three related studies in the literature. We describe the clinicopathological features of the tumor and discuss the treatment administered. The evolution was satisfactory, and the patient was submitted to oncological treatment.

Teratoma de mediastino com degeneração maligna / Mediastinal teratoma with malignant degeneration

No presente artigo, relatamos o caso de um paciente portador de teratoma de mediastino anterior, de evolução lenta, o qual foi submetido à ressecção cirúrgica. O exame anatomopatológico da peça revelou degeneração maligna para tumor carcinóide. Tal evolução é extremamente rara, sendo encontrados na literatura apenas três artigos correlatos. Apresentamos uma descrição clínico-patológica do tumor e, por fim, discutimos a conduta terapêutica. Houve evolução satisfatória, e o paciente foi submetido a tratamento oncológico.
