Familial florid osseous dysplasia: a report with review of the literature.

There are three types of osseous dysplasia: periapical cemental dysplasia (PCD), focal cemento-osseous dysplasia (FCD) and florid osseous dysplasia (FOD). While PCD is often observed in mandibular anterior teeth, FCD mainly affects mandibular posterior teeth. FOD, on the other hand, commonly involves both jaws. FOD is a type of sclerosing disease that is characterised by intense opaque masses and many areas with different densities. Genetic heritance of FOD is unusual, with only a few reported cases. We describe a case of FOD that affected three family members, discuss its clinical, radiological and histological characteristics, and review the literature.

Pilonidal sinus of the chin: mistreated as a dental fistula.

Pilonidal sinus is a chronic inflammatory condition associated with penetration of hair particles into the skin. It is rare in the chin area and, to our knowledge, there is only one such reported case. A 56-year-old man was previously admitted to a private clinic, with a hard mass on his anterior buccal sulcus. Three of the patient's teeth were extracted as the swelling was thought to be associated with a dental infection. Because the fistula did not resolve, the patient was referred to our department. Following radiological and clinical examinations, the hard mass was reached intraorally and hair shafts were seen inside it. The area was closed primarily after cleaning the inflammatory tissues and the hairs. The recovery period was uneventful. In this case report, we present a pilonidal sinus encountered in the chin area, the wrong treatment initially given to the patient and the subsequent treatment carried out by us.
