Intraosseous malignant peripheral nerve sheath tumor of maxilla: A case report with review of the literature.

Malignant peripheral nerve sheath tumor (MPNST), the principle malignancy of peripheral nerve origin, though rare in the general population, occurs with excessive frequency among patients with neurofibromatosis. This tumor always arises in soft-tissues, 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 primary intraosseous MPNST is rare and has been reported most frequently in the mandible. This article discusses a case report of MPNST of the left maxilla without a history of benign nerve tissue tumor and the diagnostic difficulties associated with MPNST.

Chronic invasive aspergillosis of paranasal sinuses: A case report with review of literature.

Aspergillosis of the nasal and paranasal sinuses is recognized as being second to candidiasis, among opportunistic fungal infections in immunocompromised patients. However, invasive variant in normal and mildly immunocompromised hosts is a very rare occurrence. We report one such case of aspergillosis involving paranasal sinuses in mildly immunocompromised patient.

Oral myiasis.

Myiasis is a relatively rare condition arising from the invasion of body tissues or cavities of living animals or humans by maggots or larvae of certain species of flies. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions; alcoholism and senility. Its diagnosis is made basically by the presence of larvae. The present article reports a case of oral myiasis involving 20 larvae in a patient with neurological deficiency.
