Introduction There are several congenital cystic conditions affecting the liver and bile ducts. The first group includes the intrahepatic cysts, which may be solitary or multiple, and their precursors, the von Meyenburg complexes. These are microscopic areas of duct ectasia which may enlarge gradually to form macroscopic cysts. The second group includes those lesions affecting the biliary drain...

BACKGROUND Pigmented intraosseous odontogenic lesions are rare with only 47 reported cases in the English literature. Among them, pigmented calcifying cystic odontogenic tumor, formerly known as calcifying odontogenic cyst, is the most common lesion with 20 reported cases. METHODS A case of pigmented calcifying cystic odontogenic tumor associated with odontoma occurring at the mandibular cani...

Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...

Calcifying cystic odontogenic tumor is an uncommon odontogenic neoplasm which is included in the heterogenous group of lesions under a broader description of Ghost cell odontogenic tumors. All these lesions have the presence of ghost cells as a common feature. Calcifying cystic odontogenic tumor is a unique lesion with variable biologic behaviour and found to occur with other odontogenic tumour...

Evaluation of enlarged follicles with unerupted teeth is always important because some changes may occur. One of the ex-tremely rare conditions seen in dental follicles is multiple calcifying hyperplastic dental follicle. We report a case of multi-ple calcifying hyperplastic dental follicle. Radiographs showed that mandibular third molars had a pericoronal radiolucent zone delineated by a well-...

The calcifying odontogenic cyst was first reported by Gorlin et al. in 1962. At that time, it was classified as a cyst related to the odontogenic apparatus, although it was later renamed as a calcifying cystic odontogenic tumor by the WHO calcification in 2005 due to its histological complexity, morphological diversity and aggressive proliferation [2]. Here, we describe a case of a calcifying c...
