Background: The calcifying odontogenic cyst (COC) is a rare example of a developmental odontogenic cyst. COC may clinically be diagnosed as calcifying epithelial odontogenic tumour, adenomatoid odontogenic tumour, ameloblastic fibroodontoma, complex or compound odontoma, dentigerous cyst or as other types of odontogenic cysts. Purpose: The aim is to present an unusual clinical case of COC assoc...

BACKGROUND This study aimed to compare the histological and immunohistochemical characteristics of ameloblastomas (AM) and ameloblastic carcinomas (AC). MATERIAL AND METHODS Fifteen cases of AM and 9 AC were submitted to hematoxilin and eosin (H&E) and immunohistochemical analysis with the following antibodies: cytokeratins 5,7,8,14 and 19, Ki-67, p53, p63 and the cellular adhesion molecules ...

About 6 months ago he experienced a pain in the gum?, followed soon afterwards by a swelling in the left upper jawbone, close to the molar teeth. The swelling gradually enlarged, and at the time of admission extended from the posterior part of the left upper maxillary bone forwards and inwards across the median line, towards the right side, as far as the right canine tooth and upwards to the ma...

BACKGROUND Restenosis of the carotid artery is common following carotid endarterectomy, but analysis of lesion composition has mostly been based on histological study of explanted restenotic lesions. This study investigated the ability of 3T cardiovascular magnetic resonance (CMR) to determine the components of recurrent carotid artery disease and examined whether these differed from primary at...

Cemento-ossifying fibroma (COF) is a rare benign fibro-osseous tumor. The radiographic and clinical features of this lesion are unpredictable and variable. In this report, the pa ent was a 12-year old girl with a painless swelling which demonstrated an opaque lesion with radiolucent zone to involve left posterior portion of the mandible on panoramic radiography. The radiographic manifestation o...

Introduction: To increase breast MRI specificity, [1,2] better assessment of lesion morphology is needed. This is especially true for differential diagnosis of fibro-adenomas, which present with DCE curves similar to those of malignant lesions. Furthermore, the smaller the lesion, the more difficult it is to assess its morphology. Yet, it is these small lesions where high specificity is paramou...

In vertebrates, activation of innate immunity is an early response to injury, implicating it in the regenerative process. However, the mechanisms by which innate signals might regulate stem cell functionality are unknown. Here, we demonstrate that type 2 innate immunity is required for regeneration of skeletal muscle after injury. Muscle damage results in rapid recruitment of eosinophils, which...

Les tumeurs conjonctives cutanées sont des tumeurs dermiques et/ou hypodermiques relativement fréquentes. Elles sont dominées par les tumeurs bénignes. A travers une série de 121 cas, nous avons étudié le profil épidémiologique, anatomopathologique et évolutif de ces tumeurs. C'est une étude rétrospective réalisée au service d'anatomie pathologique du CHU Mohammed VI de Marrakech entre 2004 et ...
