Other lesions of salivary glands

Haemangioma of the infants

It is usually a congenital, large and painless lesion. The aspirate contains a large amount of blood in which proliferative endothelial cells are seen. Since it is usually only followed up without surgery, the correct diagnosis in this early age is very important.

Congenital lesion, following puberty it disappears. Still it may become very large ( up to 3 – 5 cm! ) hence in some cases it should be removed. The differential diagnosis is very simple: we usually get only peripheral blood. In some smears ( like in this one ) vulnerable, malignant looking endothelial cells may be present. Cave: the lesion is almost always benign!

All these images are showing the typical structure of a benign peripheral nerve sheet tumor, even the Verocay body ( V ) is visible. The cells of this lesion are more fibroblastoid, elongated than epithelioid.

Lymphangioma

There is only yellowish slightly bloody fluid in the aspirate which hardly contains any cellular material. The cystic lesion refills usually in a couple of minutes after the aspiration.

Peripheral nerve sheet tumor

The tumor is connected to the facial nerve in the parotid region, which results in the fact that the aspiration procedure is painless. The cytological pattern resembles the histologic one, even Verocay body like structures are found. The cells are arranged in sheets; they are elongated, benign-looking mesenchymal cells.
