The live and let live pseudo-cyst: A Classic Rare Case of the Simple Bone Cyst.

Background and Setting: In 1992, WHO proposed the term "solitary bone cyst" (SBC) for lesions first stated by Lucas in 1929 and by Blum in 1932. Hemorrhagic cyst, traumatic cyst, pseudocyst, simple bone cyst, extravasation cyst and idiopathic bone cavity are other synonyms for this lesion. SBC represents approximately 1% of all jaw cysts. They are especially common in the long bones (90%), mainly the humerus and femur, in proximity to the epiphyseal plate, and very few (10%) cases occur in the jaws. The mandible is more commonly affected than maxilla; the area most prone being the body of the mandible between canine and third molar. The lesion is common in young males, especially during the second decade of life. The simple bone cyst is a pseudocyst devoid of an epithelial lining and is usually empty or contains blood or straw-colored fluid. The present case reviews a solitary/ simple bone cyst in the mandible, of an 18year-old otherwise healthy male; who had a trauma. The lesion was asymptomatic and was discovered on routine radiographic examination. Surgical curettage of the lesion was done, following which the patient has recovered well, and has been on regular follow-up
