“…The lesions of KD tend to infiltrate into surrounding fat tissue [4,6], therefore, diffuse loss of T1-weighted normal hyperintensities of fat suggests that the lesions grow and infiltrate as if they replace the normal fat tissue. Malignant tumors in this area such as mu-coepidermoid carcinoma of accessory parotid gland tend to break SMAS and grow into deep space of the face [15]. In our cases, no interruption of SMAS was found.…”

Background and Purpose: Kimura's Disease (KD) is a rare benign chronic eosinophlic inflammatory disorder, characterized by angiolymphoid proliferation with peripheral eosinophilia and elevated serum immunoglobulin E. Most lesions occur in the head and neck regions. To the best of our knowledge, the relationship between subcutaneous cheek lesion of KD and the surrounding structures including superficial musculoaponeurotic systems (SMAS) has never been reported. The purpose of this study was to describe MR imaging findings of cheek subcutaneous lesion of KD and adjacent SMAS. Materials and Methods: Seven cheek subcutaneous lesions of 5 patients histopathologically proved KD were evaluated. We retrospectively evaluated the MR imaging findings of subcutaneous lesions for signal intensity in each imaging sequence, the border of the lesions, and appearance of SMAS. Results: All cheek lesions were displacing normal fat tissue. These lesions showed ill-defined border (7/7), slightly high signal intensity on T1-weighted images (7/7), and intermediate (1/7) or high signal intensity (6/7) on T2-weighted images. Cheek lesions were enhanced by intravenous injection of gadolinium to signal intensity close to that of fat tissue (3/4), and in one case, the avid enhancement of the mass was seen (1/4). All lesions attached to the outer surface of SMAS, however, only one out of 7 lesions distributed below the SMAS without tearing of the layers. SMAS below the lesion showed high signal intensity on T2-weighted images in two lesions (2/7). Conclusion: KD should be included in the differential diagnosis when a cheek mass presents with non-specific signal intensities and irregular border, which attaches to but does not interrupt SMAS on MR imaging.

Introduction. We are presenting a rare case of a patient who developed simultaneous tumors in the main parotid gland (MPG) and an accessory parotid gland (APG). The APG tumor was not recognized when the more prominent MPG tumor was excised. We will discuss the clinical features of this case. Case presentation. A 66-year-old woman was referred to our department with a painless right cheek mass. Her past medical history was notable for a right MPG tumor excision at the age of 62. A retrospective review of the original MRI films revealed that a small APG tumor was present prior to the removal of the MPG tumor. Conclusion. Although the coincidental presence of the MPG and APG tumors is quite rare, this case shows the importance of identifying the smaller and potentially more sinister lesion involving the APG when it is present while preparing for the MPG tumor excision.

Tumors of the Accessory Lobe of the Parotid Gland: A 10‐Year Experience

Abstract: Neoplasms of the accessory parotid gland are rare. Management of these tumors include a high index of suspicion, good understanding of the anatomy, and meticulous surgical approach.
