Primary Intraosseous Squamous Cell Carcinoma Arising from Parakeratinized Kerato - Cystic Odontogenic Tumor Associated with Impacted Mandibular Canine: A Rare Entity.

Primary intraosseous carcinoma (PIOC) that arises from the epithelial lining of odontogenic cyst is a rare entity that represents about 1-2% of all oral and maxillofacial carcinoma. In particular, PIOC arising from keratocystic odontogenic tumor (KCOT) is rare when compared with such occurrence in other odontogenic cysts such as radicular cyst, residual cyst, and dentigerous cyst. Th e following case report discusses a case of squamous cell carcinoma arising from parakeratinized KCOT associated with impacted mandibular canine in a 43-year-old male patient with a complaint of painful swelling in the mandible. A review of reported cases from 1981 of PIOC arising from KCOT alone is also included.

Nonsurgical management of vascular malformation of masseter.

Intramuscular vascular anomalies are rare congenital hamartomatous lesions. Less than 1% of these occur in skeletal muscle out of which 15% arise in head and neck musculature. In the head and neck region, masseter muscle is the most common site. It accounts for about 5% of intramuscular vascular malformations. They are present from birth but are clinically apparent during infancy and childhood and occasionally during adulthood. Due to its location it is often mistaken for a parotid swelling. The usual treatment of choice is surgical excision with a margin. This is associated with loss of motor function, hemorrhage, nerve damage. Intralesional sclerotherapy, embolization are nonsurgical alternatives for treatment of slow flow venous malformations. Sclerotherapy can be used solely in multiple sittings or as an adjunct to surgery. This article presents a case report of a 28‑year‑old male with recurrent intramuscular vascular malformation in the masseter muscle, which was successfully treated by ethanol sclerotherapy.

PICA.

"PICA" means perverted appetite for substances not fit as food or of no nutritional value such as, bricks, clay, soil, ice, laundry starch, etc. The word ''PICA'' is derived from Latin word for Magpie, a species of bird that feeds on whatever it encounters. ''PICA'' has been observed in ethnic groups worldwide in primitive and modern cultures, in both sexes and in all age groups. The case presented here reports a 30 year old female patient who had craving for ingestion of gravel and brick fragments since the age of 13 years. Iron deficiency anemia was found after complete blood count and iron studies. The diagnosis of "PICA" requires that the patient is persistently eating non-food substances for at least 1 month and such behavior is appropriate for the child's stage of development.

Autosomal-dominant osteopetrosis: An incidental finding.

Osteopetrosis is a descriptive term that refers to a group of rare, heritable disorders of the skeleton. Osteopetrotic conditions vary greatly in their presentation and severity, from just as an incidental finding on radiographs to causing life-threatening complications such as bone marrow suppression. It is caused by failure of osteoclast development and function. Osteopetrosis can be inherited as autosomal-recessive, autosomal-dominant or as X-linked traits, with the most severe forms being the autosomal-recessive ones. The severity of the disease is mild to moderate in the autosomal-dominant forms, with normal life expectancy. Diagnosis is largely based on clinical and radiographic evaluation. The present paper reports a case of autosomal-dominant osteopetrosis complicated by osteomyelitis with a short review of the condition.
