Conclusion

Although many of the salivary gland tumors are benign, in this case the irregular contour, the irregular vascularity and the presence of an enlarged lymphe node, we found the mass very suspicious for a malignant tumor with a lymphe node metastasis. We performed an ultrasound guided biopsy of the mass and the enlarged lymphe node. The conclusion of the pathologist was: Malignant parotid gland tumor acinic type with lymphe node metastasis.
