Results: ZACDs were identified in 15 subjects out of 600, giving an overall prevalence of 2.

Oral histoplasmosis.

Histoplasmosis is a systemic fungal disease that takes various clinical forms, among which oral lesions are rare. The disseminated form of the disease that usually occurs in association with Human Immunodeficiency Virus (HIV) is one of the AIDS-defining diseases. Isolated oral histoplasmosis, without systemic involvement, with underlying immunosuppression due to AIDS is very rare.

Sublingual epidermoid cyst: a case report.

Of all the epidermoid cysts encountered throughout the body, only 7% occurs in the head and neck area, with the oral cavity accounting for only 1.6%. Intraorally this benign slow growing and painless entity is usually located in the submandibular, sublingual and submental region.

Localization of impacted permanent maxillary canine using single panoramic radiograph.

Background And Objectives: The objective in localization is selection of a suitable technique which has minimal radiation dose, cost and maximum details. Panoramic radiograph, being a screening radiograph, can satisfy the above needs. Taking this into consideration, the present study was done to evaluate the reliability of panoramic radiograph in localization of impacted permanent maxillary canines by applying the criteria suggested by Chaushu et al.

Central schwannoma of mandible.

Intraoral schwannomas are uncommon and intraosseous ones are even rarer. The intrabony lesions account for less than 1% of the central neoplasms.According to the literature, there have been reports of 44 cases of intrabony neurilemmomas that occurred in either of the jaws.

White spongy nevus: a nonhereditary presentation.

White spongy nevus (WSN) is a rare hereditary dyskeratotic hyperplasia of the mucous membranes. It is an autosomal dominant disorder with variable penetrance. A few cases of WSN occur due to de novo mutations.

Stature estimation using odontometry and skull anthropometry.

Objective: To investigate the possibility of estimating height from odontometry and anthropometric data of the skull for the positive identification of height in forensic investigations concerned with fragmentary human remains.

Materials And Methods: The study was carried out on 100 Mysorean patients, 50 males, and 50 females. Measurements of mesiodistal widths of the six maxillary anterior teeth, circumference of the skull, and height were made directly on each patient.

Burkitt's lymphoma in an Indian girl: a case report.

Burkitt's lymphoma (BL) is a rare monoclonal proliferation of B-lymphocytes and is classified as a poorly differentiated lymphocytic lymphoma. This tumor was first noted in Africans. The cause of this tumor is debatable, but strong evidence implicates Epstein-Barr virus in its development.

Facial plexiform neurofibroma in a child with neurofibromatosis type I: a case report.

Plexiform neurofibroma is a non-circumscribed, thick and irregular benign tumor of the peripheral nerve sheath. It is a virtually pathognomonic and often disabling feature of neurofibromatosis type I. The diffuse and soft nature of plexiform neurofibroma is often compared to 'a bag of worms' and is difficult to distinguish from a vascular malformation or a lymphangioma, thus necessitating thorough clinical and histopathological examination and imaging of the lesion.

Klestadt's cyst: a rarity.

Klestadt's cyst, more commonly known as the nasolabial cyst is an uncommon, non-odontogenic, soft tissue cyst characterized by its extra osseous location in the nasal alar region. Following its description first by Zukuerkandl in 1882, only 267 cases have been found in English literature. A case of nasolabial cyst in a 30-year-old female patient is presented.

Malignant peripheral nerve sheath tumour: an elusive diagnosis.

Malignant peripheral nerve sheath tumour (MPNST) also termed as spindle cell malignancy of the peripheral nerve Schwann cells or neurogenic sarcoma, represents approximately 10% of all soft tissue sarcomas. This tumour is usually found in the lower extremities and only 10-12% of all lesions occur in the head and neck region, which makes it a rare entity. The diagnosis of MPNST has been described as one of the most difficult and elusive diagnosis in the soft tissue diseases because of its non-specific presentation both clinically and histopathologically.

Extragingival pyogenic granuloma.

Pyogenic granuloma is a well-known localized granulation tissue overgrowth in reaction to mild irritation. Although it is known to show a striking predilection for the gingiva, it can be found extragingivally with varying clinical features that sometimes may mimic more serious lesions such as malignancies. The clinical diagnosis of such an uncommon extragingival pyogenic granulomra can be quite challenging.
