Two Neandertal specimens from El Sidrón, northern Spain, show evidence of retained left mandibular deciduous canines. These individuals share the same mitochondrial (mtDNA) haplotype indicating they are maternally related and suggesting a potential heritable basis for these dental anomalies. Radiographs and medical CT scans provide evidence of further more extensive dental pathology in one of t...

Introduction A ganglion cyst can induce symptoms around the knee and should be considered as an intra-articular mass in differential diagnosis. Case Presentation A 22-year-old female presented with a persistent medial knee joint pain in her left knee for 2 years. There was soft tissue swelling on the anteromedial aspect of the infrapatellar region on her left knee. Lachman and McMurray tests ...

Median raphe cyst is a rare lesion located on the median raphe. The cyst wall is lined by cuboidal to columnar cells, transitional (urothelial) cells, stratified squamous cells or a mixture of these. The normal urethral mucosa and the median raphe cyst usually lack melanocytes and/or melanin pigment. However, albeit extremely rare, the presence of melanin pigment and/or melanocytes in median ra...

Introduction: Dentigerous cyst is an asymptomatic, slow growing swelling commonly associated with the impacted third molars and is a true developmental pathology. The distinction between dentigerous cyst and a hyperplastic follicle is unclear on the routine radiographs and poses a diagnostic enigma. Case report: This report describes a case of an incidentally discovered dentigerous cyst associa...

Dentigerous cyst in maxillary sinus, especially in children, is uncommon in Malaysia. Few cases of dentigerous cyst in maxillary sinus in children have been reported in the medical literature. According to Tay AB et al, dentigerous cyst was accounted for 2.3% of the 20 most common diagnosed oral tumors in Singapore form year 1993--1997. This report illustrates a case of the dentigerous cyst in ...

A 32-year-old woman with a choledochal cyst (Todani type I) developed recurrent acute pancreatitis leading to calcific chronic pancreatitis. She had previously been treated with two cyst drainage procedures and subtotal cyst excision. This association between choledochal cyst and chronic pancreatitis has not been previously reported. Severe continuing symptoms led to pylorus-preserving proximal...

A dentigerous cyst or follicular cyst is an odontogenic cyst thought to be of developmental origin associated with the crown of an unerupted tooth. Such cyst remain initially asymptomatic unless infected. The purpose of this case report is to describe the diagnosis and management of dentigerous cyst in a 7.5 year-old boy. The chosen treatment was marsupialization which responded well with erupt...

STUDY DESIGN A cadaveric study OBJECTIVE.: The aim of this study was to analyze the in situ macro- and microscopic configuration of the type II cyst and its anatomic relationship with surrounding structures. SUMMARY OF BACKGROUND DATA The lack of consensus of surgical strategy to manage symptomatic type II meningeal cysts (Tarlov cysts) is because our knowledge of type II cyst anatomy remains...

Glandular odontogenic cyst (GOC) is an uncommon developmental cyst. It accounts for 0.012% to 1.3% of all the jaw cysts; its prevalence is 0.17%. It was described by Gardner et al. in 1988 as a distinct entity. GOC has a slight predilection for mandible and affect more commonly in the middle-aged patients. Radiographic and clinical features of this cyst are not pathognomonic or specific. Only t...

Hydatid pulmonary embolism is an uncommon condition resulting from the rupture of a hydatid heart cyst or the opening of a visceral hydatid cyst (often in the liver) into the venous circulation. We report a case of hydatid pulmonary embolism following rupture of a hydatic cyst in the right ventricle. Pulmonary angiography showed right pulmonary occlusion. Echocardiography, computed tomography s...
