An Unusual Clinical Presentation of Kimura Disease Manifesting with a Typical Cephalocervical Lesion and an Atypical Subcutaneous Hip Mass Lesion

Abstract

Kimura's disease (KD) is a rare lymphoproliferative inflammatory disorder, typically presenting as firm, painless or pruritic single or multiple subcutaneous lesions in the head and neck, especially in the parotid and submandibular regions. We herein report a case of a 39-year-old Japanese man presenting with a typical cephalocervical KD lesion around the salivary glands with a rare association with a distant subcutaneous mass at the hip. We also emphasize the radiologically and clinically important features in the differential diagnosis and management. To the best of our knowledge, this case is the first report of KD manifesting with a typical cephalocervical lesion and an atypical subcutaneous hip mass lesion.
