Ewing sarcoma of the adrenal gland: a case report and review of the literature.

Background: Ewing sarcoma/primitive neuroectodermal tumor is a family of highly malignant proliferation of neuroectodermal origin, most often skeletal, adrenal localization is extremely rare. Only few cases have been reported in the literature. Classical management includes radical surgery with adjuvant chemotherapy or radiotherapy or both.

[Tympanic paraganglioma mimicking cholesteatoma: about a case].

Tympanic paragangliomas are common benign tumors of the middle ear, made up of neuroendocrine cells dispersed along the major vascular axes of the head, the neck and the vertebral column. The revealing symptoms are hearing loss and a pulsatile tinnitus. Otoscopy often shows pulsatile retrotympanic reddish mass.

[Adrenal myelolipoma: about a case].

Adrenal myelolipoma is a rare benign non secreting tumor. It is often unexpectedly detected. Pathophysiologically, it is adrenal cortex cell metaplasia into reticuloendothelial cells, resulting from infection, chronic stress or adrenal gland degeneration.

[Epidermoid cyst in the sella turcica: about a case].

Epidermoid cyst (EC) or cholesteatoma is a benign tumor, often of congenital origin, occurring in the sub-arachnoidian spaces. Its treatment is based on surgery. We report the case of a 38 year-old patient presenting with progressive intracranial hypertension syndrome associated with anterior pituitary insufficiency signs of the corticotropic, thyrotropic, gonadotropic axis occurring 1 year before.
