Atypical histiocytic granuloma of the tongue: case report.
Primary malignant lymphomas of the tongue have rarely been described, and reported cases are usually related to the posterior part of the tongue which is rich in lymphoid tissue, forming part of Waldeyer's ring. Making a distinction between pseudolymphoma and malignant lymphoma is important. Pseudolymphoma is a benign lesion not requiring aggressive therapy. Several lesions in the oral cavity, including atypical histiocytic granuloma, angiolymphoid hyperplasia with eosinophilia, and traumatic ulcerative granuloma with stromal eosinophilia have been described as having certain microscopic features similar to those of pseudolymphoma. Atypical histiocytic granuloma is not associated with systemic disease or dissemination and heals spontaneously despite its microscopic appearance.
