各論⑤ 耳下腺より前方のほぼ同じ場所に発生し，病理診断がすべて異なった頬部皮下腫瘍の4例

Four Cases of Subcutaneous Facial Tumors with Different Pathdogical Diagnoses Arising from the Anterior Position of the Parotid Gland

はじめに

　顔面部の皮下腫瘍は，形成外科の日常診療で多く遭遇する疾患の1つである。そして，顔面の深部には耳下腺や副耳下腺および顔面神経などの臓器が存在し，それらから皮下腫瘍が生じることも多い。今回われわれは，頬部皮下のほぼ同じ部位に発生し，病理診断がすべて異なった4例を経験した。頬部に生じた皮下腫瘤の診療を行ううえで，それらの腫瘤の診断と鑑別は非常に重要と考えられたので報告する。

　Subcutaneous facial tumors are frequently encountered in plastic surgery practice. There are parotid glands, parotid glands, and facial nerves in the face, and tumors may develop from these. We have treated four patients with subcutaneous facial tumors that occurred at almost the same subcutaneous site of the cheek and were diagnosed differently based on pathology findings. These cases emphasize that it is important to differentiate such findings in the diagnosis and treatment of subcutaneous tumors of the cheek.
