We report the case of a patient who presented with cystic lymphoid hyperplasia of the right parotid gland as the index diagnosis of HIV infection. Histological examination of the excised parotid gland revealed a solid-cystic lymphoepithelial lesion with a non-keratinous squamous epithelium, which grew into the lymphoid component via anastomosing cords and islands. These anastomosing cords and islands contained variably abundant B cells, several subepithelial multinucleated histiocytes, salivary ducts infiltrated by small lymphocytes, and a dense lymphoid infiltrate containing lymphoid follicles with enlarged, irregular germinal centres.

Nasal metastases from colorectal cancer is rare. The presentation of nasal metastases is often very similar to primary nasal sinus adenocarcinoma. A high index of suspicion is required, especially in patients who have had a previous history of colorectal carcinoma. Histology is ultimately required for diagnosis. We describe 2 cases of nasal metastases from colorectal carcinoma, and discuss the presentation, diagnosis and management of the case. Such metastatic disease ultimately represents end-stage malignancy, and patients should be palliated.
