Nodular Fasciitis of the Zygomatic Area: A Case Report and Its Aesthetic Considerations

ABSTRACT

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.
