摘　　要：BACKGROUND Nodular fasciitis(NF)is a benign disease originating from fascial tissue and most commonly occurs in the extremities,followed by the trunk,head,and neck.NF of the head and neck occurs mainly in the face and neck,and it has not been reported in the occipital region.CASE SUMMARY A 30-year-old man was admitted because of a mass in the left occipital region.Imaging examination revealed a soft tissue nodule in the left occipital area.An enhanced magnetic resonance imaging scan showed characteristic inverted target and fascial tail signs.Histopathological analysis showed a large amount of spindle cell proliferation,and immunohistochemistry showed positive expression of SMA in the spindle cells in the lesion.Finally,nodular fasciitis was diagnosed.CONCLUSION NF of the head and neck is rare,but the possibility of NF should be considered when nodules or masses with rapid subcutaneous growth are found and tenderness in the head and neck is present.Imaging examination,in combination with clinical manifestations and histopathological examination,can improve the diagnostic accuracy for the disease.After diagnosis,local surgical resection is the first choice of treatment.
