Follicular dendritic cell sarcoma associated with Castelmans disease presenting in the oral cavity

Follicular dendritic cell sarcoma (FDCS) is a rare intermediate grade malignant neoplasm of reticular dendritic origin. Castleman’s disease (CD) represents a non-neoplastic lymphoproliferative disorder with various clinical and morphological features. FDCS has been reported to be associated with CD. In this article, we describe the first case of follicular dendritic cell sarcoma associated with Castleman’s disease presenting in the oral cavity. Copyright © 2005 Elsevier Ltd All rights reserved.

Oral granular cell tumour of the lip in an adult patient

Oral granular cell tumour is a rare soft tissue tumour of mesenchymal origin. The most frequently affected site in the oral cavity is the tongue, followed by the floor of mouth, and buccal mucosa. In paediatric patients, 25% of cases have been reported to occur in the lip, but this presentation in adults is extremely rare. We report a case of oral granular cell tumour in a 35 year-old female, located in the lower lip. Histopathological examination revealed eosinophilic granular cells which stained positively for S-100 protein; a finding supportive of a neural origin. A history of trauma was elicited in this case, and the lesion was treated with surgical excision.
