Florid osseous dysplasia a rare benign fibro-osseous multiquadrant dysplastic lesion confined to the alveolar process of jaws, generally asymptomatic and usually detected incidentally during radiologic examination and requires no treatment unless symptomatic or cosmetically concerning. In this article, we present two rare cases of florid osseous dysplasia in Indian women with their clinical, radiographic and histologic findings and a brief review of literature is discussed. The first case was asymptomatic and the lesion was detected during routine radiographic examination and required no treatment whereas, the second case presented with features of osteomyelitis. Based on the clinical findings, the case was diagnosed as chronic suppurative osteomyelitis, but, after radiologic examination, diagnosis of florid osseous dysplasia with secondary osteomyelitis was made. Besides diagnostic challenge, management of the lesion is difficult due to poor vascularity. In our case, antibiotic prophylaxis along with surgical debridement and sequestrectomy was done with regular recall visits. © 2017, Journal of Clinical and Diagnostic Research. All rights reserved.

Osteopetrosis is a rare genetic bone disorder arising due to a defect in the differentiation or function of osteoclast which results in a generalized increase in bone mass. Osteomyelitis is one of the most common complications because of decreased bone marrow function and compromised blood supply. Radiologist plays a vital role in diagnosing osteopetrosis. Here, we present two cases of autosomal dominant osteopetrosis Type II (ADO II) with secondary osteomyelitis changes which were reported to our department. One of these two cases presented with secondary osteomyelitis in both maxilla and mandible and features of rickets, which is very rarely seen in ADO II. To the best of our knowledge, the presentation of rickets with ADO is the first of its kind to be reported. In this paper, we describe the clinical and radiological features leading to the diagnosis of ADO in these two patients. Further, a review of the literature regarding ADO is discussed. © 2017 Indian Journal of Dental Research | Published by Wolters Kluwer-Medknow.

Every treatment in the dental specialty has its own set of complications, Orthodontic therapy being no exception. Such a problem during the course of treatment puts the specialist in a dilemma as to whether to continue or stop the treatment. One such case in which during headgear therapy, a rare complication such as alopecia was encountered has been dealt with in this paper. This case report shows its effective management while still continuing treatment, thus leading to the desired result. It emphasizes on the importance of maintaining a balance between the benefits and risks of a treatment. Clinical relevance: The use of headgear can lead to the rare complication of alopecia and the clinician should be aware of it. Objective: The reader should understand the psychological implications of alopecia and also to carry out the treatment after assessing the risk/benefit ratio.

Unicystic ameloblastoma (UCA) is a clinical subtype of ameloblastoma that is considered prognostically different. The purpose of this report is to present a case of UCA showing dual radiographic pattern in a child. A detailed study of the lesion was carried out in an 8 year old female child who presented to our department of oral and maxillofacial pathology. Clinical, radiological and histopathological findings were recorded. In March 2005, a painless swelling in the left side of the mandible was noted, which on radiographic examination showed a unilocular radioluceny enclosing the crown of mandibular left permanent second molar, extending between the left first permanent molar and anterior margin of the ramus. Histopathologic diagnosis was UCA. The lesion was treated by enucleation. The patient returned with recurrence in 2009, at this time the lesion radiographically presented as a multilocular radiolucency with a soap bubble appearance, extending between the anterior border of the ramus and second premolar. Histopathologic diagnosis was UCA. The lesion was treated by segmental resection with immediate reconstruction. Although a number of treatment modalities are available to treat UCA, many factors need to be taken into consideration in the treatment of UCA in children.

Objective: This hospital-based study was designed to provide demographic data on odontogenic tumors from the southern Indian population in the state of Tamil Nadu for comparison with pertinent series from other geographic regions. Study design: A total of 489 cases of odontogenic tumors registered over a period of 38 years (February 1970-March 2008) in the Department of Oral and Maxillofacial Pathology of Tamil Nadu Government Dental College and Hospital, Chennai, India, were retrieved from the files of histopathology registers and were retrospectively analyzed. Results: Odontogenic tumors in the present study constituted 4.13% of all the 11,843 registered biopsies. The mandible was the most commonly affected anatomic location, with 362 cases (74.02%). Ameloblastoma with a predilection for posterior mandible was the most frequent odontogenic tumor (67.69%), followed by adenomatoid odontogenic tumor (9%), odontoma (7.77%), and calcifying odontogenic cyst (5.52%). The patients were affected over a wide age range of 5-75 years with a mean age of 32.64 years and peak occurrence in the second and third decades of life. Among the 489 cases, only 15 (3.07%) were malignant. Conclusion: The relative frequency of 4.13% of odontogenic tumors observed in this study, which is the largest series from this part of the world. Ameloblastoma formed the single most common tumor of all odontogenic tumors. This study observed both regional and geographic variations in the frequency and distribution of odontogenic tumors. © 2010 Mosby, Inc. All rights reserved.

Background: Fibro-osseous lesion are a group histologically similar lesions but with characteristic clinical and radiographic features. The definitive diagnosis of these lesions requires integration of clinical, radiological, histological, and gross surgical features. Ossifying fibroma is an encapsulated lesion that is often found in the mandible of middle-aged females. Case report: We report a case of ossifying fibroma in a 25-year-old female with associated non-specific cystic changes and mimicking simple bone cyst. Conclusion: The case reported here is diagnostically challenging and requires proper integration of clinical, radiological, histological, and gross surgical features to reach definitive diagnosis. © 2011 Springer-Verlag.

Extramedullary plasmactyoma is the solitary, soft tissue form of plasma cell neoplasm but lack the defining features of medullary or multiple myeloma. The diagnosis is difficult to make in routine practice setting due to the morphological and immunohistochemical overlap with plasmablastic lymphoma. We report a case of plasmablastic extramedullary plasmacytoma in a 52-year-old in the mandibular lingual gingiva and discuss its differential from plasmablastic lymphoma. The gingival mass regressed with primary radiotherapy.

Lichen planus, a chronic autoimmune disease, affects the skin and mucous membrane. It is characterized by alternating periods of symptomatic remission and exacerbation. Different treatment modalities have been tried with limited success. Presently, treatment of lichen planus aimed at alleviating symptoms during periods of exacerbation and to prolonge the duration of remission. A regular follow-up of patients is required as there is high risk of malignant transformation in few types of oral lichen planus.

There have been a number of papers that have addressed the issue of plagiarism. Nevertheless, the charges of plagiarism usually merit little attention with experts, because it is still not clear what sort of copying actually constitutes plagiarism. Another problem that eludes consensus is whether plagiarism was committed with or without intention. This paper discusses certain issues relating to plagiarism and differentiates between intentional and unintentional forms of plagiarism. © 2011 Blackwell Publishing Asia Pty Ltd.

Objectives. Data are not available regarding distribution of minor salivary gland tumors from the specialist pathology setting in India. The purpose of this study was to determine the relative frequency and distribution of minor salivary gland tumors and to compare the data with pertinent studies. Study design. The records and archival samples of the Department of Oral and Maxillofacial Pathology, Tamil Nadu Government Dental College and Hospital, Chennai, India, served as source material for this retrospective study. All cases with a diagnosis of minor salivary gland tumors recorded between 1971 and August 2008 were retrieved and reviewed. Results. A total of 185 minor salivary gland tumors were identified with reference to the latest World Health Organization classification, representing a relative frequency of 1.52% over the study period of 37 years (1971-2008) from 12,147 biopsy samples. Malignant tumors (75%) predominated over benign tumors (25%). The age range was 12-82 years with a mean of 46 years. Mucoepidermoid carcinoma was the most frequent tumor (34%), followed by pleomorphic adenoma (22%), adenoid cystic carcinoma (15%), and polymorphous low-grade adenocarcinoma (10%). The overall gender distribution was almost equal. Palate was the most frequent involved site, followed by alveolar mucosa and floor of the mouth. Conclusions. The present study shows a higher proportion of malignant tumors and a tendency toward male predilection during the past decades. The overall data are consistent with hospital-based studies from Asia and series from other geographic regions. © 2011 Mosby, Inc.
