Nodular Fasciitis – Fine Needle Aspiration Cytology Diagnosis and Its Pitfalls, with Review of Literature

Background and objective: nodular fasciitis (nf) is a self-limiting, transient neoplasm composed of fibroblasts and myofibroblasts. since it regresses spontaneously, diagnosis by fine needle aspiration (fna) cytology plays a major role in its management. methods: we present a series of 8 cases with either fna or biopsy diagnosis of nf, and study the major cytological features with a review of literature on diagnostic criteria and its pitfalls. results and conclusion: the 8 cases occurred in patients between the age of 14 to 72 years, with equal sex distribution. fna diagnosis concurred in 4 cases. causes of wrong diagnosis included lack of clinical information and paucicellular smear. fna cytology is an important tool in the diagnosis of nodular fasciitis, in appropriate clinico-radiological setting.
