A pleomorphic adenoma or mixed tumor is a heterogeneous benign tumor of the salivary glands. The most frequent site is the parotid gland. It is rare in the accessory salivary glands, preferably located in the oral mucosa (roof of the mouth, floor of the mouth, cheeks, and lips). The diagnosis of pleomorphic adenoma of the palate can only be made on a biopsy while remaining vigilant about the possible existence of other neoplastic foci within it. Definitive anatomopathology after excision is mandatory. Here, we present a clinical case of pleomorphic adenoma of the palate. We propose to specify the epidemiological, diagnostic, and therapeutic particularities of these tumors as well as their evolutionary characteristics.

The sphenoethmoidal meningocele is a herniation of the meninges through a communication of the skull base with an aeric cavity. It means the presence of an osteomeningeal breach, which is manifested by cerebrospinal rhinorrhea and nasal obstruction. iIs diagnosis is based on a very specific radiological assessment and biology allows the dosage of certain substances to confirm the nature of the cerebrospinal fluid, such as beta-2-transferrin, Once the breach has been found, the endoscopic route exclusively allows the pathology to be treated and the defect to be reconstructed using different materials before the occurrence of serious complications such as meningitis.
