Abstract
BACKGROUND Intravascular papillary endothelial hyperplasia is an unusual vascular lesion characterized by the proliferation of endothelial cells. The aim of this study was to determine the frequency and general features of this lesion. METHODS Biopsy records of three oral pathology services were reviewed for intravascular papillary endothelial hyperplasia cases from 1959 to 2020. In addition, a systematic review of case reports and case series was carried out in eight electronic databases. RESULTS Of the 65 205 retrieved cases, 20 (0.03%) were diagnosed as intravascular papillary endothelial hyperplasia. Mean patient age was 46.55 years, and females (12 cases/60%) were more affected. The lower lip (9 cases/47.36%) was the most commonly affected site, and the lesions were generally asymptomatic (7 cases/63.63%). Clinically, 90% of the lesions presented (18 cases) as a nodule, with a mean size of 1.13 cm. The clinical diagnostic hypotheses most frequently raised were mucocele (6 cases/37.50%) and hemangioma (5 cases/31.25%). An excisional biopsy was chosen in all cases for treatment. Forty-nine studies of the systematic review were included, yielding 105 cases. The literature showed similarity in all variables. CONCLUSION Despite the uncommon frequency, clinicians and oral pathologists should familiarize themselves with the similarities between intravascular papillary endothelial hyperplasia and some other lesions in terms of clinical and histological features.

Abstract
INTRODUCTION The purpose of this study was to analyze the features of lesions obtained from biopsies at the periapical area of teeth with a radiographic or clinical initial diagnosis of apical periodontitis. METHODS A retrospective study was conducted on biopsies obtained from 1953-2018 at 3 Brazilian oral and maxillofacial pathology centers. Cases of endodontic and nonendodontic periapical lesions (NPLs) with a clinical diagnosis of endodontic pathoses were retrieved. Data regarding patient age, sex, and anatomic location were obtained from patients' records. The frequency and percentage of cases with clinical diagnoses of a periapical cyst, periapical granuloma, or dentoalveolar abscess were recorded, and the final histopathologic diagnosis was documented. RESULTS Among 66,179 oral biopsies, 7246 (10.94%) were clinically diagnosed as periapical disease, 306 (4.22%) of which were histopathologically diagnosed as NPLs. The most frequent NPLs were odontogenic keratocysts (n = 107, 34.96%) followed by dentigerous cysts (n = 48, 15.68%). The mean age at diagnosis was 39.68 years with a range of 6-80 years. A total of 159 (51.96%) cases occurred in females and 147 (48.03%) in males (female to male ratio = 1.08:1). Most lesions (137, 44.77%) were located in the posterior mandible. CONCLUSIONS A wide variety of histopathologic diagnoses, including benign odontogenic and nonodontogenic cystic and tumorous lesions, infectious diseases, and malignant neoplasms, was reported in the present survey. The features presented in this study were consistent with previous findings reported in the literature.

Abstract
The xyloglucan from cotyledons of Hymenaea courbaril was hydrolysed with endo-(1,4)-beta-D-glucanase (cellulase) and analysed by TLC and HPAEC. The limit digest was different from those obtained from xyloglucans of Tamarindus indica and Copaifera langsdorffii. On treatment with nasturtium beta-galactosidase, two main oligosaccharides were detected by TLC and HPAEC. Using a process of enzymatic sequencing involving alternate treatments with a pure xyloglucan oligosaccharide-specific alpha-xylosidase, and a pure beta-glucosidase, both from nasturtium, their structures were deduced to be XXXG and a new oligosaccharide XXXXG. These structures were confirmed by 1H NMR. The relative proportions of XXXG and XXXXG indicate that approximately half of the subunits in Hymenaea xyloglucan are based on the new oligosaccharides. In the native polymer the XXXXG subunits are likely to carry galactosyl substituents in varying proportions, since cellulase hydrolysates contained many bands which were converted to XXXXG on hydrolysis with nasturtium beta-galactosidase. Although no comparative studies on the physico-chemical properties of Hymenaea courbaril xyloglucan have yet been performed, our results indicate that this polymer is less interactive with iodine when compared with T. indica and C. langsdorffii xyloglucans, suggesting that changes in conformation may occur due to the presence of XXXXG.
