MULTIFOCAL NATURE OF ADENOLYMPHOMA OF THE PAROTID

The multifocal nature of adenolymphoma of the parotid salivary gland w as studied in 24 patients who underwent parotidectomy. Twenty-six rese cted specimens were examined by a step-serial whole-organ sectioning t echnique; multiple adenolymphoma was found in 13. The maximum number o f synchronous tumours in any gland was four. Salivary epithelial eleme nts were found embedded within lymph nodes in nine resected specimens. Synchronous or metachronous bilateral tumours were found in eight pat ients. The multifocal nature of adenolymphoma of the parotid gland is demonstrated.
