Pleomorphic Adenoma Originating from Heterotopic Salivary Tissue of the Upper Neck: A Diagnostic Pitfall

Figure 3

(a) Macroscopic aspect of the level IIA mass after surgical excision: well-delineated white solid lesion with tumor margin smaller than 0.1 cm (red stars). (b) Histopathology (original magnification, ×25; HE stain) revealing that the well-delineated tumor (lower part of the picture) is surrounded by a normal serous salivary gland (arrowheads), thus suggesting the diagnosis of pleomorphic adenoma of an ectopic minor salivary gland.
