Peripheral Calcifying Odontogenic Cyst : a rare case report
2018
The Calcifying Odontogenic Cyst (COC) is a simple cyst lined by ameloblastoma-like epithelium with ghost cells. The peripheral COC is a rare lesion and few reports have been published considering its clinical and histopathological features. This article aimed to report on a case of a peripheral COC, discussing its clinical, imaginological and histopathological features. A 9-year-old male patient presented a 10x5 mm painless nodule in the palatal mucosa of the left central incisor. Panoramic, occlusal and periapical radiographs did not show alterations. A computed tomography exam showed a slight soft tissue swelling located in the palatal mucosa of the left maxillary central incisor. An exci…
The unusual evolution of a simple bone cyst in the mandible: a case report
2012
The simple bone cyst, as newly classified by WHO in 2005, is a lesion related to the jawbones. Therefore, it is not a cyst, since it is a cavity devoid of epithelial tissue. It is a rare pathology affecting the mandible more than the maxilla. Its onset occurs mainly during the first two decades of life, irrespective of sex. The purpose of our report is to exhibit the particular case of a 17-year-old male patient whose radiography showed an osteolytic lesion in his right mandibular body. Exploratory surgery and biopsy are performed showing a simple bone cyst. Since then, he is controlled through imaging studies, but presenting an atypical evolution, with its size increasing considerably with…
Extramammary Paget Disease of the Axilla Associated With Comedo-like Apocrine Carcinoma In Situ.
2002
Extramammary Paget disease of the axilla with underlying apocrine carcinoma has been reported only in six cases until now. This report deals with a seventh case characterized by the unique finding of comedo-like features evocative of large cell ductal breast carcinoma within an otherwise typical in situ apocrine carcinoma. This is characterized by spiral-shaped foci of epithelial proliferation with decapitation secretion and central masses of necrotic debris. A possible connection between the solid neoplasm and the overlying Paget disease is illustrated by a few apocrine-follicular units colonized by both the Paget cells and the structured adenocarcinoma. Here, although they display the sam…
Inflammatory papillary hyperplasia: a systematic review
2017
Introduction Inflammatory papillary hyperplasia (IPH) is a benign lesion of the palatal mucosa. It is usually found in denture-wearers but also has been reported in patients without a history of use of a maxillary prosthesis use. Objetives The aim of this study is to review the literature to assess the prevalence of denture stomatitis and inflammatory papillary hyperplasia and the etiological factors associated. Material and Methods A search was carried out in PubMed (January 2005 to October 2015) with the key words “inflammatory papillary hyperplasia”, “denture stomatitis”, “granular stomatitis” and “Newton’s type III” The inclusion criteria were studies including at least a sample of 50 a…
GLANDULAR ODONTOGENIC CYST ASSOCIATED WITH AMELOBLASTOMA: CASE REPORT AND REVIEW OF THE LITERATURE
2017
Glandular odontogenic cyst (GOC) associated with ameloblastoma is an exceedingly rare histologic presentation with no known clinical significance or treatment applications. Four cases have been reported, three in the mandible and one in the maxilla. The age range is 14-65 and with male predilection. All four presented with swellings and two with pain. We add one more case to the literature of a 58-year old male presenting with an expansile multilocular radiolucency between teeth #19-23. The ameloblastomatous changes in this case are consistent with those of a unicystic ameloblastoma-mural subtype. Although the histologic changes are those of a unicystic ameloblastoma, the clinical and radio…
Fibro-osseous lesion of maxilla. Report of two cases in a family with review of literature
2011
Fibrous dysplasia is a disturbance of bone metabolism that is classified as a benign fibro-osseous lesion. Fibrous connective tissue containing abnormal bone, replaces normal bone. The etiology of fibrous dysplasia is unknown. The radiographic appearance of the irregularly shaped trabeculae aids in the differential diagnosis. Occurring most commonly in the second decade of life, the lesions of fibrous dysplasia can be surgically recontoured for esthetic or functional purposes once they become dormant.
Malignant peripheral nerve sheath tumor of the maxila
2005
Summary We present a case of a malignant peripheral nerve sheath tumor [MPNST] of the maxilla corresponding to a 12 year old male who had a painful, ulcerated rapid growing tumor. Histology revealed the presence of a tumor consisting of fusiform cells with abundant mitosis, with negative cytokeratins, actin, desmin, myoglobin and factor VIII. In contrast, the protein S-100 was positive. MPNST was not associated with signs of Neurofibromatosis Type 1. The patient was surgically intervened and received radiotherapy, then died within 10 months posterior to surgical intervention after suffering recurrence.
Giant cell granuloma of the maxilla. Global management, review of literature and case report.
2012
Giant cell granuloma is a relatively rare benign entity but can be locally aggressive. Histologically characterized by intense proliferation of multinucleated giant cells and fibroblasts. Affects bone supported tissues. Definitive diagnosis is given by biopsy. Clinically manifest as a mass or nodule of reddish color and fleshy, occasionally ulcerated surface. They can range from asymptomatic to destructive lesions that grow quickly. It is a lesion to be considered in the differential diagnosis of osteolytic lesions affecting the maxilla or jaw. Its management passed from conservative treatment with intralesional infiltration of corticosteroids, calcitonin or interferon, to the surgical rese…
Pterygium axillae as a rare manifestation of Poland syndrome
2016
Abstract Poland syndrome is characterized by a combination of absent pectoralis muscle, abnormalities of the rib cage, the breast, as well as brachy-syndactyly. We report a case of a 3 month old girl who was born with right sided axillary pterygium combined with flattening of the right anterior chest wall. Resection of a sclerotic band with reconstruction by Z-plasty was performed. Intraoperative and histopathological findings confirmed that the axillary pterygium developed on the basis of a scarred, hypoplastic pectoralis major muscle. Our case adds to the body of evidence that Poland syndrome may present in a heterogeneous fashion, including the rare finding of axillary pterygium with ass…
Experimental models of orthodontic tooth movement and their effects on periodontal tissues remodelling.
2021
Made available in DSpace on 2022-04-29T08:31:31Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-10-01 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Objectives: The present study aimed to compare two different models of orthodontic tooth movement (OTM) in rats by evaluating tooth movement efficiency and periodontal tissues remodelling. Design: Fifteen animals were randomly distributed into 3 groups: control group (untreated); ligature appliance (LA) as experimental OTM using a closed coil spring fixed around maxillary first molar by steel ligature; occlusal appliance (OA) as experimental OTM using a closed coil spring attached on the occlusal surface of the maxillary f…
