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 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...

Calcifying fibrous pseudotumor is a rare, benign, hypocellular tumor-like lesion that is characterized by the presence of dense hyalinized collagenous tissue interspersed with small spindle cells, dystrophic calcifications, or psammomatous and variable lymphoplasmacytic infiltrations. We report the case of a 37-year-old woman with a posterior mediastinal mass, in close contact with the distal t...

Corticosteroid injections are a common nonsurgical treatment of intersection syndrome, flexor carpi radialis tendonitis, flexor carpi ulnaris tendonitis, and medial epicondylitis. The benefits of corticosteroid injections for these conditions have been well studied and documented in the medical literature. Patients with less common upper extremity complaints usually first present to their prima...

Ultrasonography (US) has proved to be a useful diagnostic tool in patients with shoulder pain and/or limited range of motion. It allows careful assessment of a wide range of changes involving many different anatomic structures of the shoulder girdle, such as the rotator cuff tendons (tendonitis, tendon tears and calcific deposits), the long head of the biceps tendon (tenosynovitis, tendonitis, ...
