1/56. Maxillofacial hydatid cysts.We report 2 cases of hydatid cysts occurring in the submandibular gland and buccal submucosa, respectively. Our first case occurred in the submandibular salivary gland of a 20-year-old woman and the second involved the buccal submucosa of a 6-year-old boy. Both diagnoses were made after the excision of the lesions. Both patients were evaluated after surgery, and both were followed up, but no other organs were involved.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
2/56. Bacillary angiomatosis affecting the oral cavity. Report of two cases and review.Bacillary angiomatosis (BA) is an infectious disease characterized by proliferative vascular lesions; it mainly affects hiv-positive patients. Multiple cutaneous nodular lesions together with fever, chills, malaise, anorexia, vomiting and headache are the most important clinical manifestations. It may also involve the heart, liver, spleen, bones, lung, muscles, lymph nodes, central nervous system and other organs. erythromycin, 500 mg four times a day, is the drug of choice. The importance of this lesion lies in its clinical and histological similarity with other diseases. Cutaneous and oral lesions of BA clinically resemble Kaposi's sarcoma (KS). Histopathologically, BA may be confused with angiosarcoma, pyogenic granuloma and epithelioid hemangioma. We report two hiv-positive men with BA lesions in the oral mucosa. diagnosis was confirmed by biopsy and Warthin-Starry silver staining.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
3/56. Lower lip numbness due to peri-radicular dental infection.Lower lip numbness has always been a sinister symptom. Much has been written about it being the sole symptom of pathological lesions and metastatic tumours in the mandible. It may also be a symptom of manifestations of certain systemic disorders. A case of lower lip numbness resulting from the compression of the mental nerve by a peri-radicular abscess is presented because of the unusual nature of this spread of infection.- - - - - - - - - - ranking = 0.075567956818925keywords = nerve (Clic here for more details about this article) |
4/56. Acute porphyric disorders.Acute porphyrias are classified into 3 distinct groups of rare genetic disorders of metabolic enzyme biosynthesis. Acute porphyrias can significantly impact multiple organ systems, which often provides a challenge to the dentist presented with such a patient. A case of hereditary coproporphyria is reported in a patient with many of the classical signs and symptoms. The patient also had complex dental needs that required special medical and pharmacotherapeutic modifications. The acute porphyrias are reviewed by the authors with presentation of this challenging case. Recommendations for other dental health care professionals encountering these patients are then presented.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
5/56. Langerhans' cell histiocytosis restricted to the oral mucosa.Langerhans' cell histiocytosis comprises a group of disorders with Langerhans' cell proliferation as a common feature. The clinical presentation might be highly varied. Typically, there is bone involvement and, less frequently, lesions might be found in other organs, particularly the lungs, liver, lymph nodes, skin, and mucosae. Lesions limited to the oral mucosa are rare. We describe two patients with unifocal eosinophilic granuloma exclusively limited to the oral mucosa. triamcinolone acetonide infiltration of a palatal lesion yielded a good result in one patient. Six months later, a similar lesion developed in the mandibular gingival mucosa, but it responded to the same treatment. The lesion in the other patient responded to local radiotherapy.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
6/56. Pigment in the lining of nasopalatine duct cysts: report of two cases.In a review of 20 nasopalatine duct cysts, two cases were encountered with a pigmented epithelial lining. In the literature we have found one similar case only. The pigment in our cases was shown to be melanin. The authors suggest that the melanin-containing epithelial cells are derived from Jacobson's organs and, therefore, most likely should be considered olfactory epithelium.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
7/56. Orofacial paraesthesia: an unusual presentation of acoustic neuroma.patients with acoustic neuromas commonly present with unilateral hearing loss, tinnitus and unsteadiness. An uncommon initial feature is involvement of the trigeminal nerve. The unusual feature in the case reported here was orofacial paraesthesia, which preceded hearing loss by 3-4 years. diagnosis was made following a referral by the patient's dentist.- - - - - - - - - - ranking = 0.075567956818925keywords = nerve (Clic here for more details about this article) |
8/56. tuberous sclerosis: presentation of a clinical case with oral manifestations.tuberous sclerosis (TS) is a genetic disorder affecting multiple body systems, and resulting from alterations in cell differentiation and proliferation. The disease is characterized by the development of benign hamartomatous tumors: neurofibromas and angiofibromas, located in the skin, central nervous system, mucosas and other organs. Abnormal neural cell migration plays an important role in the neurological dysfunctions found in TS, the predominant features being mental retardation, seizures and behavioral disorders. The condition is produced by mutations in genes TSC1 of chromosome 9q34 and TSC2 of chromosome 16p13.3, and exhibits a dominant autosomal hereditary trait--though 60-70% of cases are sporadic and represent new mutations. The phenotype is highly variable. The prevalence of TS varies between 1/6000 and 1/10,000 live births. The present study reports the case of a 21-year-old male with TS and oral manifestations of the disease. The clinical characteristics are described, along with the diagnostic criteria and the management strategies, with a review of the literature on the disease.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
9/56. Tumour of the juxtaoral organ.The juxtaoral organ is a normal and constant structure of the oral cavity. It consists of benign epithelial nests. We describe an intraoral tumour of the juxtaoral organ in a child. The tumour was not diagnosed after clinical and radiological examinations because it is extremely rare. A histological examination revealed a tumour of the juxtaoral organ, presumed to be neuroid hamartoma. This is only the second time that a tumour of the juxtaoral organ has been described in a child. We also describe the location, the embryology, the histology and the function of this organ. This is important because this structure can be confused with carcinomas of the oral cavity when examining frozen sections.- - - - - - - - - - ranking = 9keywords = organ (Clic here for more details about this article) |
10/56. Sebaceous adenoma of oral cavity: report of case and comparative proliferation study with sebaceous gland hyperplasia and Fordyce's granules.Sebaceous adenoma (SA) is a rare solitary tumour with a predilection for the forehead and scalp. In the English literature, less than 10 cases of SA have been described in the oral cavity. The objective of this study was to examine the clinicopathologic features and evaluate the expression of epidermal growth factor and its receptor, estrogen receptor and androgen receptor in SA and in its differential diagnoses including sebaceous gland hyperplasia (SGH) and Fordyce's granules (FG). Additionally, we analysed the proliferative potential of sebaceous cells from SA, SGH and FG by measuring proliferating cell nuclear antigen (PCNA) expression and quantification of argyrophilic nuclear organizer regions (AgNORs). The SA showed many clinicopathologic similarities to cases previously reported including the biphasic population of cells, in the periphery of lobules undifferentiated basaloid cells whereas the central area was formed by mature sebocytes. SA was composed of 198 lobules of sebaceous cells, whereas SGH and FG showed a mean of 21 /- 7.81 and 5.84 /- 2.83, respectively. The AgNOR and PCNA indices were similar in SA, SGH and FG. These data suggest that lobule counts may be used as additional criteria in distinguishing SA of the oral cavity from other intraoral sebaceous gland lesions.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
