[Clinical analysis of nodular fasciitis in the head and neck]

Objective: To analyze the clinical features, diagnosis, treatment and prognosis of nodular fasciitis (NF) in the head and neck. Methods: Seven cases of primary NF in the head and neck admitted to Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from 1990 to 2022 were retrospectively analyzed, including 3 males and 4 females, aged from 2 to 67 years, and the location, course of disease, clinical manifestations, imaging findings, and treatment results of the disease were summarized. Results: Of the 7 patients, the primary sites were respectively nasal vestibule, paranasal sinus, nasal dorsum, sella turcica and clivus, neck, subglottis, and tonsil. Three cases presented with rapidly growing subcutaneous painless masses within 2 months, 1 case presented with hemoptysis, hoarseness and asthma for 28 days, 1 case presented with blood in the nasal discharge for 2 months, 1 case presented with headache for 1 month, and 1 case was found to have tonsillar neoplasms on physical examination for 3 days. CT was performed in 5 patients and the lesions showed soft tissue density shadows, and MRI was also performed in 2 of them, which showed T1 isointensity or T2 slightly long abnormal signal shadows. All patients underwent simple surgical resection of the mass. The patients were followed up for 13 months to 10 years, and none had recurrence. Conclusion: Primary NF in the head and neck is rare, with atypical clinical symptoms and imaging findings. Surgery is the mainstay of treatment for NF with good results.
