Nodular fasciitis is the most common benign mesenchymal tumor that can be mistaken both
clinically and pathologically for soft tissue sarcoma due to its infiltrative growth pattern. It most
commonly appears in the extremities and trunk. However, occurrence in the zygomatic area is
extremely rare. We present a case of 28-year-old man, who was characterized with a firm, tender,
clearly visible mass in his left zygomatic area. We performed a local excision, together with microscopic
and immunohistochemical analysis. The mass was eventually diagnosed as nodular fasciitis
in the zygomatic area. No postoperative oncological treatment was done and the postoperative
follow-up was maintained up to the present time without any tumor recurrence. Nodular fasciitis
should be considered in the differential diagnosis when a rapid growing subcutaneous mass is
detected in this area. Accurate diagnosis, appropriate treatment and follow-up are mandatory to
avoid overly aggressive treatment and limit treatment-related morbidities. Moreover, the disease
itself and its surgical treatment may cause aesthetic compromise and the aesthetic implications have
been discussed. (J Korean Soc Aesthetic Plast Surg 17: 51, 2011)
