Abstract
Background
Nodular fasciitis (NF) is a rapidly growing, self-limiting, subcutaneous nodular cytologic exuberant fibroblastic/myofibroblastic proliferation prone to cytological misdiagnosis.
Aims
This study aimed at finding out the utility of fine needle aspiration cytology (FNAC) from NF patients and to validate the diagnostic features.
Materials and Methods
The study group comprised 11 cases diagnosed as NF on cytology or subsequent histology.
Results
Out of 11 cases, 9 were cytologically diagnosed as NF. Two cases were misdiagnosed as sarcoma as proven histologically. Of the 9 cases of NF, spontaneous resolution occurred in 7 cases in 2-16 weeks; excisional biopsy was undertaken in the other 2 cases.
Conclusion
On cytology, NF reveals hypercellular, polymorphic, dispersed cell population, which is most commonly misdiagnosed as sarcoma. For this reason, FNAC has to be correlated with clinical data and followed up for the anticipated spontaneous regression.
