in 1991, handlers and colleagues described the central odontogenic fibroma (cof) as a distinct entity which is a rare benign odontogenic tumour and up to the present, only 78 cases of it have been published. cof usually occurs in an adult patient and has a predilection for the anterior region of the jaws. a 2.8:1 female to mail ratio is typically noted. this article presents a case of cof in a ...

Catecholamine-producing tumors may arise in the adrenal medulla (pheochromocytomas) or in extraadrenal chromaffin cells (secreting paragangliomas). Their prevalence is about 0.1% in patients with hypertension and 4% in patients with a fortuitously discovered adrenal mass. An increase in the production of catecholamines causes symptoms (mainly headaches, palpitations and excess sweating) and sig...

Cutaneous metastases (CM) from solid organ tumors have a reported incidence of 0.5% to 10%. They most often occur in breast, lung and kidney primaries. Often regarded as the ‘first sign silent visceral metastases,’ they are associated with poor prognosis. The concurrent has not been studied detail. A better understanding CM could mechanistic management implications. aim our study was determine ...

Fine needle aspiration cytology (FNAC) has established itself as a diagnostic modality in various visceral and soft tissue lesions. However its usage in the diagnosis of different bony lesions has not received much attention. Open surgical biopsy is considered as the procedure of choice for obtaining diagnostic tissue sampling of bone tumors (Kreicbergs et al., 1996). Apart from being an inpati...
