“…Metastases of primary tumours located below the clavicle are reported to make up 10-20% of all parotid metastases. As also seen in our patient group, where 13% were metastases of tumours below the clavicle, primary tumours are mostly located in the lung, breast and kidney, and more rarely seen in the gastrointestinal tract, prostate and infraclavicular skin 24 - 30 .…”

“…1,9 Small cell carcinomas in the parotid glands rarely originate locally, 10 and are more often metastatic tumours from other organs such as the lung. 11 Distant metastasis to the parotid gland is a very rare clinical event. To the best of our knowledge, only six cases have been reported (Table 1).…”

“…On morphology, the differential diagnosis may include solid variant of adenoid cystic carcinoma, 4,6,13,17 highgrade mucoepidermoid carcinoma, 6,13,17 high-grade adenocarcinoma, 4,6,13,17 Merkel-cell carcinoma, 5,17 lymphoma, 5,13,17 and extrasalivary metastasis of small-cell carcinoma. 5,[21][22][23][24][25][26] Immunohistochemically, small-cell carcinoma of the salivary glands usually expresses at least one neuroendocrine marker 9 such as Leu 7, synaptophysin, chromogranin, or neuron-specific enolase, and shows cytokeratin staining, 9,10 often in a punctate or globular paranuclear pattern. 9,10 Staining with epithelial membane antigen 9 and vimentin 9 has also been reported.…”
