Ulcerated oral lichen planus of the lower lip, common disease with the uncommon presentation: A case series.

Dermatologic diseases are often associated with oral manifestations and sometimes the oral lesions are the sole presenting features of the disease. Diagnosing a dermatologic disease based on its oral manifestations is a challenge, especially in the absence of associated cutaneous lesions. Lichen planus is a common dermatologic disease that affects the oral mucosa in the adult population. While some patients have concomitant oral and cutaneous lesions, the oral lesions are persistent and seen for years together even after the cutaneous lesions have healed. Herein, we present two cases of oral lichen planus seen as an ulcerated lesion on the lower lip which is an uncommon manifestation of this otherwise common disease.

Paget disease of bone: A classic case report.

Paget disease of bone (PDB) is a chronic progressive disease of the bone of uncertain etiology, characterized initially by an increase in bone resorption, followed by a disorganized and excessive formation of bone, leading to pain, fractures, and deformities. It can manifest as a monostotic or polyostotic disease. The prevalence of PDB is common in the Anglo-Saxon population, but relatively rare in India. The disease is often asymptomatic and commonly seen in an aging population. The diagnosis of the disease is mostly based on radiological examination and on biochemical markers of bone turnover. Markedly elevated serum alkaline phosphatase (SAP) is a constant feature while calcium and phosphate levels are typically within normal limits. It is being successfully treated by biphosphonates, a group of anti-resorptive drugs, thereby decreasing the morbidity and mortality associated with the disease. We report a classic case of PDB with craniofacial involvement resulting in Leontiasis Ossea (lion like face), cotton wool appearance of the skull and elevated SAP.

Oral presentation in dengue hemorrhagic fever: A rare entity.

One of the major health hazards which is prevalent and dangerous is the dengue fever which causes the death of many people. This may be associated with a variety of mucocutaneous manifestations which may be of help in early diagnosis. Many biochemical assays and hematological investigations may aid in the further diagnosis and treatment of the fatal disease. Oral lesions are rare to occur and if present, are often mistaken for platelet abnormality. This case report highlights the importance of oral lesions and it is the first of its kind to be reported as dengue hemorrhagic fever.

Talon cusp in fused teeth: A rare concomitant occurrence.

Talon cusp and fusion of teeth are two separate developmental dental anomalies affecting both primary and permanent dentitions. While the former is more common in permanent maxillary incisors, the latter occurs more commonly in deciduous maxillary anterior teeth. This paper describes a rare case of talon cusp in fused teeth affecting the permanent mandibular incisors. A note on the etiopathogenesis of these two anomalies and a possible hypothesis on their concurrent occurrence are mentioned. The importance of awareness and understanding of these lesions and the prophylactic measures to prevent complications is also discussed.

Imaging in the diagnosis of cemento-ossifying fibroma: a case series.

Cemento-ossifying fibroma is a benign fibro-osseous lesion belonging to the same category as fibrous dysplasia and cementifying dysplasia. These are slow-growing lesions that are seen in the third and fourth decades of life. Both the ossifying fibroma and cemento-ossifying fibroma represent two extremes of the same disease process since histologically both contain bone and cementum. However, the term cemento-ossifying fibroma is justified on the basis of clinical and radiological correlation. Radiographs have become an essential tool in the diagnosis of lesions in the jaw, where the anatomy is complex. Nowadays, CT provides information for diagnosis as well as treatment planning. In this case series, we report three cases of cemento-ossifying fibroma that were histologically confirmed and discuss the imaging findings.

Adenoid cystic carcinoma of the mobile tongue: A rare case.

Adenoid cystic carcinoma (ACC) occurs more commonly in the minor salivary glands of the palate on than the tongue. ACC is a malignant neoplasm that accounts for 1-2% of all head and neck malignancies and 10-15% of all salivary gland malignancies. ACC affects the exocrine glands at any site, but the parotid gland is the most common site in the head and neck region. Many factors should be taken into account in the prognosis of ACC, including the histological and clinical stages of the disease. The most striking feature of ACC is that it is locally aggressive, with a high recurrence level, perineural invasion and distant metastases, especially to the lungs and bones. The most common presentation histologically is the presence of cribriform appearance (Swiss cheese pattern). The present case is a rare one present on the tongue.

Adenomatoid odontogenic tumor - a report of two cases with histopathology correlation.

Adenomatoid odontogenic tumor (AOT) is an uncommon, hamartomatous, benign, epithelial lesion of odontogenic origin that was first described by Driebaldt in 1907, as a pseudo-adenoameloblastoma. The current World Health Organisation (WHO) classification of odontogenic tumors defines AOT as being composed of the odontogenic epithelium in a variety of histoarchitectural patterns, embedded in mature connective tissue stroma, and characterized by slow, but progressive growth. The current article reports two cases with different presentations; first in a young female patient and the second in a middle-aged male patient. The importance of biopsy, which is the gold standard for diagnosis, and its use in planning of the treatment is discussed.
