THREE CASES OF NODULAR FASCIITIS: PRIMARY DIAGNOSES BY FINE NEEDLE ASPIRATION CYTOLOGY

Dear Editor Fine needle aspiration cytology (FNAC) has been used increasingly in the diagnosis of soft tissue tumours. Pseudosarcomatous lesions, including nodular fasciitis (NF), are important in di€erential diagnosis of sarcoma. NF is considered to be a self-limiting reactive process rather than a true neoplasm. The head and neck region is the most common location in infants and children, in contrast to adults in whom upper extremity, chest and back are more common sites. Practically all lesions are solitary, nodular, non-encapsulated mass and usually measure 2 cm in greatest diameter. Although the lesion resolves spontaneously in a few months without surgery, it is usually diagnosed by excisional biopsy. Reports on the cytologic features of NF are limited. Below we describe the features of aspiration cytology of three cases of NF in which spontaneous complete resolution occurred following diagnosis by FNAC.
