1. Common pitfalls in renal mass evaluation: a practical guide
Resumo Mais da metade dos pacientes com mais de 50 anos de idade pode ter pelo menos uma lesão renal focal detectada de modo incidental em estudos de imagem, como ultrassonografia, tomografia computadorizada ou ressonância magnética. Embora a maioria dessas lesões possa ser facilmente caracterizada, erros de diagnóstico podem ocorrer e geralmente estão

2. Hairy Tongue: Differential Diagnosis by Use of Widefield Optical Fluorescence
Resumo A língua pilosa é uma patologia benigna, caracterizada clinicamente por placas hiperqueratinizadas na face dorsal da língua, semelhante a pelos, cuja coloração varia de despigmentada, esbranquiçada, amarelada, verde, acastanhada a preta. O diagnóstico é clínico, e em casos de placas esbranquiçadas, pode ser difícil diferenciar entre leucopl

3. Oral plasmablastic lymphoma as the first manifestation of AIDS
Abstract Plasmablastic lymphoma is a non-Hodgkin lymphoma characterized by its plasmacytic differentiation and predilection for the oral cavity. It is among the lymphomas most commonly associated with AIDS. This report details a case of a HIV-positive patient with a 1-month history of an exophytic mass in the gingival area of the upper left quadrant. The dia

4. Accuracy of clinical diagnosis for the identification of potentially malignant disorders and malignant lip lesions
Abstract: The aim of this study was to assess the accuracy of clinical diagnosis for lip lesions based on sensitivity and specificity. The retrospective analysis focused on the detection of lesions caused by potentially malignant disorders (PMDs) and malignant lesions (n = 1195). All cases were classified as benign, PMD, and malignant lesions. Concordance be

5. Agreement between clinical and histopathologic diagnoses and completeness of oral biopsy forms
Abstract The present study aimed to assess the rate of agreement between clinical and histopathological diagnoses and to report the frequency of completed forms for specimens that were subjected to histopathological examination and retrospectively examined. Data from 8,168 specimens submitted to histopathological examination were retrieved from the records.

6. Immunoexpression of cleaved caspase-3 shows lower apoptotic area indices in lip carcinomas than in intraoral cancer
ABSTRACT Objective This study aimed to evaluate apoptosis by assessing cleaved caspase-3 immunoexpression in hyperplastic, potentially malignant disorder (PMD), and malignant tumors in intraoral and lower lip sites. Material and Methods A retrospective study using paraffin blocks with tissues from patients with inflammatory fibrous hyperplasia (IFH), act

7. Adult granulosa cell tumor of the testis masquerading as hydrocele
Adult testicular granulosa cell tumor is a rare, potentially malignant sex cord-stromal tumor, of which 30 cases have been described to date. We report the case of a 43-year-old male who complained of a left testicular swelling. Scrotal ultrasound showed a cystic lesion, suggestive of hydrocele. However, due to a clinical suspicion of a solid-cystic neoplasm

8. Oral potentially malignant disorders in a large dental population
Objectives Oral cancer (OC) may be preceded by clinically evident oral potentially malignant disorders (OPMDs). Oral carcinogenesis is a multistep process that begins as epithelial hyperplasia and progresses to oral epithelial dysplasia and finally to fully malignant phenotypes. The aim of our study was to estimate the prevalence of OPMDs in a large popula

9. Sphenoid Sinus Inverted Papilloma: A Case Report and Literature Review
Introduction Inverted papilloma is a rare benign tumor of the nasal fossa, which usually originates from its lateral wall. Only 5% of cases demonstrate exclusive sinus involvement. Primary sphenoid sinus involvement is even rarer. Although considered a benign lesion, the tumor has a potentially invasive nature and has also been found to have an associated m

10. Atividade gelatinolítica in situ e imuno-expressão das metaloproteinases 2 e 9 em lesões potencialmente malignas e carcinomas espinocelulares bucais / In situ gelatinolytic activity and immunoexpression of metalloproteinases 2 and 9 in oral potentially malignant lesions and squamous cell carcinomas
The transition from normal oral mucosa to invasive carcinoma has a complex and multifactorial etiology. Oral leukoplakia (OL) is regarded as the most prevalent potentially malignant oral lesion, with a higher tendency for malignant transformation if compared to normal oral mucosa. Although an increased activity of matrix metalloproteinases (MMPs) 2 and 9 in

11. Oral leukoplakia manifests differently in smokers and non-smokers
Oral leukoplakias (OL) are potentially malignant lesions that are typically white in color. Smoking is considered a risk factor for developing OL, and dysplastic lesions are more prone to malignant transformation. The aim of this study was to describe the clinical features observed in dysplastic and non-dysplastic OL in both smokers and non-smokers. A total

12. Leucoplasia verrucosa proliferativa X leucoplasias oral: um estudo clínico comparativo e análise crítica dos critérios de diagnóstico / Proliferative verrucous leukoplakia X oral leukoplakia: a comparative clinical study and a critical analysis of diagnostic criteria
A leucoplasia verrucosa proliferativa (LVP) é classificada como um subtipo da leucoplasia oral (LO), de rara incidência e alto potencial de malignização. Acomete com maior frequência pacientes do gênero feminino, acima da sétima década de vida e apresenta altos índices de recorrência após a realização de qualquer modalidade de tratamento. Seu as
