Incidental Fine Needle Aspiration Cytology (FNAC) diagnosis of primary Hydatid cyst in Axillary region - A rare case report in unusual location

Fine Needle Aspiration Cytology (FNAC) diagnosis of primary Hydatid cyst

Abstract

Hydatid cysts develop most frequently in the liver and lungs, but are occasionally found in other organs. Solitary subcutaneous hydatid cyst is uncommon and the only symptom is generally a silent growing mass. Primary hydatid cysts in the axillary region are extremely rare even in areas where the disease is endemic, with only eighteen cases reported in the literature.(1,9) We have reported a case of asymptomatic subcutaneous axillary swelling in a young female incidentally diagnosed on FNAC. This case report emphasises that the possibility of hydatid cysts should be considered as cause for palpable lesions in axillary region especially in endemic locations.
