Importance of the dentist in early diagnosis of pemphigus vulgaris
Thiago de Santana Santos,Marta Rabello Piva,Paulo Nand Kumar,Paulo Ricardo Saquete Martins Filho
RGO : Revista Gaúcha de Odontologia , 2009,
Abstract: The vulgar pemphigus is a chronic, rare, vesicle-bubble disease of autoimmune origin and with a possibility of following a dangerous clinical course when it is not diagnosed and treated in its initial stage. It usually affects people from 40 to 60 years old, being rare in children. In the majority of cases, oral manifestations are the first signs of the disease, so that dentists play an important rol in its early diagnosis. The authors present a case report of vulgar pemphigus in a 17 year-old patient, attended by the Bucco-Maxillo-Facial Surgery Service of the “Funda o de Beneficência Hospital de Cirurgia” in Aracaju-SE, Brazil. The patient was admitted with a complaint of the presence of numerous scattered painful ulcers in the mouth that had developed in approximately two months, and reported that at first, blisters that broke quickly appeared, leading to extremely painful ulcerations. Incisional biopsies were performed in the jugal mucosa and retromolar regions, and also a complete hemogram to discard the hypothesis of leukemia. In view of the clinical and histopathological findings, the final diagnosis of pemphigus vulgaris was made. Before receiving specialized treatment, the patient presented marked worsening of the clinical condition, with exacerbation of intraoral signs and symptoms and development of skin lesions around the body surface. The patient was hospitalized in the “Hospital Universitário da Universidade Federal de Sergipe” and treated with prednisone, cimetidine and nystatin, showing significant improvement of symptoms in approximately two weeks. At present, the patient is under the care of an interdisciplinary team that includes dermatologists and dentists.

Abstract: inverted schneiderian papilloma (isp) is a neoplasm of epithelial lining origin which arises in the respiratory mucosa that lines the nasal cavity and paranasal sinuses. the inverted schneiderian papilloma frequently appears as a unilateral lesion in the nasal septum and extends secondarily to the nasal and paranasal sinuses. this paper reports an unusual case of this pathology with involvement of the oral cavity in a 61-year-old white man. clinical evaluation revealed a vegetating mass in the alveolar ridge of the right maxilla that had been present for approximately 4 months. after radiographic evaluation, involvement of the maxillary sinus was detected. microscopic evaluation, in situ hybridization and immunohistochemical analysis of the specimen led to a diagnosis of isp moderate dysplasia associated with hpv infection

Abstract: oral pyogenic granuloma is a hyperplastic inflammatory lesion commonly associated to local irritation or trauma. females are more affected than men probably due to the vascular effects of hormones that occur during puberty, pregnancy and menopause. in the pregnancy, the lesions are known as "pregnancy tumor" and tend to occur more frequently during the second and third trimester. in the oral cavity, histopathological examination is required for diagnosis, since the lesion is clinically indistinguishable from other reactive lesions and, usually, there is no evidence of bone involvement. the authors report a rare case of pyogenic granuloma with destruction of alveolar bone mimicking a malignant tumor in a 20-year-old woman in the 19th week of pregnancy.

Abstract: nevus is a congenital pigmented malformation rarely found in the oral mucosa. around one third of cases located in this anatomical region are of the blue type, a histological variant with considerable tendency to malignancy. this study reports the case of a male patient, chronic smoker, with a blue nevus measuring 5cm in diameter on the hard palate. since controversy exists in the literature regarding the incisional biopsy of pigmented lesions with malignant or malignant potential, excision without previous biopsy of the lesion was the therapy of choice for this case. the patient was followed-up for two years with no sign of recurrence or malignant transformation

Abstract: the traumatic bone cyst is characterized by the presence of an asymptomatic sinus devoid of epithelial lining, which is rarely found in the jaws. objective: to describe the clinical, surgical and radiographic findings of traumatic bone cysts. material and method: a retrospective study was made of patients diagnosed with traumatic bone cysts at an oral pathology department from 1992 to 2007. data on the clinical, radiographic and surgical complications were gathered. results: twenty-six cases of traumatic bone cyst were diagnosed in 15 years; 17 were male and 09 were female. most patients were within first two decades of life and had no pain or history of trauma in the affected area. the multilocular pattern was observed in only seven cases, its radiographic appearance suggests a tumor. air was found inside the lesion in about 70% of cases; serous fluid with blood and blood only were uncommon within the lesions. conclusion: a higher prevalence in young patients, absence of a history of trauma, and a small number of lesions containing serous fluid with blood reflects the need to discuss the true pathogenesis of traumatic bone cysts.

Abstract: this study investigated the immunodetection of pcna in epithelial components of dental follicles associated with impacted third molars without radiographical and morphological signs of pathosis. a total of 105 specimens of dental follicles associated with impacted third molars with incomplete rhizogenesis (between nolla's stage 6 and 9) were surgically removed from 56 patients. epithelial cell proliferating was determined by using immunohistochemical labeling. statistical analysis was performed using the fisher exact test. of the 105 dental follicles collected, 6 were pcna-positive ( 6%). the specimens with squamous metaplasia and epithelial hyperplasia had higher rates of positivity for pcna, as well as those with proliferative remnants of odontogenic epithelium. in conclusion, this study shows that dental follicles at this stage of development have low proliferative potential, but suggests that squamous metaplasia, hyperplasia of the epithelial lining and presence of proliferative odontogenic epithelial rests in the connective tissue may be early signs of developing lesions of odontogenic origin.

Abstract: this study investigated the immunodetection of ptch in epithelial components of dental follicles associated with impacted third molars without radiographic signs of pathosis. one hundred and five specimens of dental follicles associated with impacted third molars with incomplete rhizogenesis (between nolla's stage 6 and 9) were surgically removed from 56 patients. epithelial cell proliferation was determined by using immunohistochemical labeling. statistical analysis was performed using fisher exact test and a level of significance of 5%. of the 105 dental follicles collected, 3 were ptch-positive. the specimens with squamous metaplasia and epithelial hyperplasia had higher rates of positivity for ptch, as well as those with active remnants of odontogenic epithelium. this study suggests that the odontogenic cells of the dental follicle might be proliferating during the rhizogenesis, while the squamous metaplasia and hyperplasia of the epithelial lining and proliferative odontogenic epithelial rests show the differentiation potential of dental follicles.

El granuloma piógeno oral es una lesión hiperplásica inflamatoria asociada a la presencia de irritación local o trauma. Las mujeres son más afectadas que los hombres, probablemente debido a los efectos vasculares de las hormonas que se producen durante la pubertad, el embarazo y la menopausia. En el embarazo, las lesiones se conocen como "tumor del embarazo" y tienden a ocurrir con más frecuencia durante el segundo y tercer trimestres. En la cavidad oral, el examen histopatológico es necesario para el diagnóstico, ya que la lesión es clínicamente indistinguible de otras lesiones reactivas y, por lo general, no hay evidencia de afectación ósea. Los autores divulgan un caso raro de granuloma piógeno con la destrucción del hueso alveolar simulando un tumor maligno en una mujer de 20 a os de edad, en la semana 19 de embarazo.
