Malignant granuloma

Malignant granuloma

Malignant granuloma, also known as lethal midline granuloma or necrotizing granuloma, is a rare granulomatous disease of unknown etiology characterized by progressive necrotizing ulcers. This disease often begins in the nose and gradually extends to the hard and soft palate, nasopharynx, and upper lip. The affected areas rapidly develop erosions and ulcers. In later stages, metastasis may occur, ultimately leading to death from systemic failure, with a very poor prognosis.

Salivary gland tumors

Salivary gland tumors

Salivary glands, also known as salivary glands, mainly include three pairs of large glands (parotid gland, submandibular gland, and sublingual gland) and numerous small salivary glands mainly distributed in the oral mucosa. Tumors originating from all these glandular tissues are collectively referred to as salivary gland tumors. Salivary gland tumors include both benign and malignant types and are more common in middle-aged women.
