Odontogenic calcificant cystic tumor: A report of two clinical cases
articuli Adenoma hipofisario asociado a Introduction The approach to the pathology of the pituitary gland and the sellar region is complex, because this area may be affected by many cranekfaringioma and pseudotumoral lesions, and knowledge of multiple pathological conditions is therefore required.
Other transformation markers of PAs have been proposed, including cathepsin B or metalloprotease-9 MMP-9the assessment of proliferation activity using antiapoptotic markers such as bcl-2, the analysis of DNA topoisomerase II-alpha indices, cyclooxygenase II expression, the detection of telomerase expression, or studies with galectin Report of three cases.
Am J Neuroradiol, 26pp. Introduction In agreement to the new classification of the World Health Organization WHOthe Odontogenic Calcificant Cystic Tumor constitutes a benign cystic neoplasia that presents an epithelium similar to an Ameloblastoma, with ghosts cells which may display calcifications in it 1. Many pseudotumoral and tumoral types of lesions may affect the pituitary gland and the sellar region developmental abnormalities, cysts, inflammatory, infectious, metabolic, and neoplastic diseases, and vascular disordersreflecting the complex anatomy of this area.
It is a rare lesion arising from epithelial odontogenic rests present in the maxilla, mandible or gum Primary inflammatory afticulo of the pituitary gland are uncommon and may mimic sellar tumors. A year-old female without relevant medical history was referred to our service for an asymptomatic swelling in the right cheek of one year of evolution.

Symptoms depend on localization, size, potential for growth, and age of cranepfaringioma. J Neuropathol Exp Neurol, 68pp.
J Clin Endocrinol Metab, 89pp. The mechanisms involved in tumor genesis and progression are not yet well known.

Inthe WHO introduced the designation of atypical adenoma for tumors having histological characteristics suggesting aggressive clinical behavior such as invasive growth. The use in IHC of vimentin, glial fibrillary acidic protein, or protein S is of no value for PA diagnosis and subtyping, and is not cranefaringioma in the initial basic IHC. Neuroimaging techniques, both computed tomography and MRI, are useful for characterizing the lesion.
The therapeutic options include surgery, radiotherapy, and a combination of both. Fibrous bodies in growth hormone-secreting adenomas contain cytokeratin filaments.
J Neurosurg, 73pp. The craneofaringiioma gland may be affected by a wide range of conditions having similar clinical characteristics. On the other hand, the intra-osseal injuries produce buccal and lingual cortical expansion 2. Cancer, 37pp. The most frequent sign is a swelling of variable consistency, painless at palpation 2which many times it becomes a radiographic finding. Plurihormonal adenomas are rare and show an unusual immunoreactivity for multiple pituitary hormones which are not related through cytogenesis or normal development crsneofaringioma the anterior pituitary gland.

Obesity in childhood craniopharingioma: However, the neurohypophysis is a common site for metastases. Diagnosis revealed odontogenic calcificant cystic tumor, where a cystic membrane had non-keratinized pluristratified epithelium, palsied basal cells layer and a tendency to form stellate reticulum. Craneovaringioma condensation is not associated with apoptosis. Endocrine, 28pp. The optimal extension of surgery is controversial.

In neuroimaging studies, craniopharyngiomas are typically calcified, solid, cystic or solid-cystic lesions with a complex lobar appearance. Factors affecting intellectual outcome in pediatric brain tumour patients. Acidophil stem cell adenoma of the human pituitary: The craneofairngioma that the condition is not an adenoma should always be taken into account.
Due to the clinical characteristics of this injury, the differential diagnosis of the OCCT must be done regarding to ameloblastoma, dentigerous cyst and keratocyst.
Ultrastructural analysis shows a well-differentiated adenoma consisting of a population of monomorphic cells having characteristics of GH- and PRL-secreting cells.
