The paper by Saderne & Wahl addresses an interesting question of how calcifying and non-calcifying epibionts respond to ocean acidification (OA) and results are interesting as they show divergent responses to OA. However, the manuscript needs some major revisions and re-shaping is needed that should be more to the point of what can really be addressed and answered with the experiments and the a...

Calcifying epithelial odontogenic tumor is a rare lesion. We report the imaging features of a calcifying epithelial odontogenic tumor. The imaging including conventional radiograph, CT and MR imaging revealed a well-defined lesion in the alveolar bone of the left maxilla, which contained an impacted tooth and some small radiopacities. CT and MR imaging demonstrated a contrast enhancement mainly...

Calcifying epithelial odontogenic tumour (Pindborg tumour) is a rare benign neoplasm with a poorly understood histogenesis. This report describes a single case of a maxillary calcifying epithelial odontogenic tumour including immunohistochemical analysis. The vast majority of tumour cells were positive for CK5/6 and p63. Furthermore, basal cells also displayed moderate reaction for vimentin and...

OBJECTIVES The stroma-rich variant of hyaline-vascular type of Castleman's disease (SR-HVCD) should be differentiated from vascular or follicular dendritic reticulum cell neoplasms. In this paper, we present a rare case of HVCD. We also suspect a possible association between SR-HVCD and calcifying fibrous pseudotumor. METHODS A 34-year-old man was found an abdominal mass by computed tomograph...

Calcifying cystic odontogenic tumor (CCOT) previously known as calcifying odontogenic cyst (COC) is a relatively rare lesion. It was first reported as a separate pathologic entity by Gorlin et al in 1962 as a likely analog of the cutaneous calcifying epithelioma of Malherbe or pilomatricoma. Because of the diverse clinicohistologic features and the various neoplastic potential, there have been ...

Calcifying nanoparticles (CNPs, previously called nanobacteria) are self-propagating, cultivable macromolecular complexes. Their extraordinary characteristic is that they can aggregate carbonate apatite on their envelope from soluble calcium and phosphorus at physiologic concentrations and display cytotoxic effects on murine and human fibroblast cell lines. The question arises whether CNPs cont...

Calcifying epithelioma, a benign tumor derived from the hair apparatus and consisted of hair matrix cells, is relatively prevalent in females. We report a case of right preauricular calcifying epithelioma that was incidentally detected at the examination of multiple facial fractures and became an old lesion without symptoms for 40 years. The patient who was a 42-year-old male visited our depart...

the term calcifying odontogenic cyst (coc) was first introduced by gorlin in 1962. coc occurs mainly as an intra-osseous lesion in mandible or maxilla but the peripheral variation of coc has also been reported. the confusion about coc nature as cyst or tumor has not been resolved and a vast diversity has been shown in clinicopathologic aspects of coc. the purpose of this study was the review an...

Enlarged follicles associated with multiple unerupted teeth always comprise an area of considerable interest for oral and maxillofacial surgeons. The condition of multiple calcifying hyperplastic dental follicles is extremely rare and is characterized by multiple unerupted teeth with abundant calcifications and odontogenic epithelial rests in the enlarged dental follicles. We report an interest...
