Role of Fine Needle Aspiration Cytology in Diagnosis of Epidermal Inclusion Cysts of Breast: A Clinical & Radiological Dilemma
Keywords:
Benign breast lesion, Fine Needle Aspiration Cytology, Epidermal Inclusion Cyst.Abstract
Background  An epidermal inclusion cyst is a common benign lesion which can occur anywhere in the body. However, EIC occurring in the breast (EICB) is very rare. This study is aimed to analyze the incidence, clinical factors, cytomorphology with the differential diagnosis and cytohistopathological correlation with diagnostic & treatment options of this lesion & to evaluate the role of Fine Needle Aspiration in its diagnosis.
Methods:Â This is retrospective study for a span of 4 years was done in Department of Pathology at Tertiary Teaching Hospital. In this study, patients with firm breast lump with diagnosis of EICB on FNAC were included. Smears from these cases were re-evaluated by two cytopathologists and clinico-radiological and cyto-histopathological correlation was done.
Result This study included 4 female and 1 male patients with age ranging from 26-58 years. Patients presented with firm breast lump measuring from 0.5 to 2.0 cm in periaerolar region. Radiological findings were suggestive of benign breast lesion in three cases and one infective lesion in female. FNAC was performed & cytodiagnosis of EICB was made. Cytohistopathological correlation was available in four cases.
Conclusion EIC of breast is a rare entity & these lesions are often mistaken as benign or malignant tumours both clinically & radiologically. However, FNAC plays a pivotal role in providing accurate pre-operative diagnosis.
