Only a few cases of epidermal cysts of the breast have been reported in literature. Epidermal cyst is nonmalignant proliferations of squamous epithelium situated within the dermis. We have discussed in this case report one such case. This case report aims to identify rare in breast such a common lesion otherwise by means of radiological and histopathological investigation and differentiat from other lesion of breast.  Case Report: 40 year female patient with lump in left side of breast since 25 years with gradualy progressive to current size, examination show firm lesion in left side breast outer quadrant not associated with other symptoms. FNAC suggestive of epidermoid cyst with ultrasound shows heterogeneous well define lesion.  Conclusion: An epidermoid cyst presenting in breast as a lump should be differntiated from other bening breast lesion with investigation.
