Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin composed of odontogenic epithelium in a variety of histoarchitectural patterns. Most cases are in females and have a striking tendency to occur in the anterior maxilla. However, AOT of the maxillary antrum is extremely rare. A 25-year-old female presented with a large radiolucent(More)
Leiomyosarcoma (LMS) is a malignant neoplasm composed of cells showing distinct smooth muscle features. Majority of the tumors are located in the retroperitoneum, including the pelvis and the uterus but are rare in the oral and pharyngeal region. Intraorally, they are present as painless, lobulated, fixed masses of the submucosal tissues in middle-aged or(More)
Cellular automata are a simple structure which lends itself to some remarkable ideas. They are simple to construct but have the complex behaviour. They can be studied in physics, mathematics, computer science, biology to study the natural process like self-reproduction. In this paper, we are going to show that how Pascal's triangle can be created using(More)
Fungal infection of the paranasal sinuses is an increasingly recognized entity, both in normal and immunocompromised individuals. The recent increase in mycotic nasal and paranasal infections is due to both improved diagnostic research and an increase in the conditions that favor fungal infection. Although fungal infections of the paranasal sinus are(More)
The classical features of superior orbital fissure syndrome arise due to compression of all or some anatomical structures passing through the fissure. A conservative approach is advocated in this condition unless there is a bony impingement of the neuronal structure and/or simultaneous compression of optic nerve leading to blindness or diminished vision.(More)
Pleomorphic adenoma (PA) is the most common tumor of the benign salivary gland neoplasms, and the most common gland to be involved is the parotid gland. Its occurrence in the submandibular or the sublingual gland is uncommon. We present a case of a histologically proven PA involving the submandiblular gland.
