Epidermoid cysts are common benign subcutaneous lesion also termed as epidermal cysts. Epidermoid cyst are commonly seen in hairy regions of body like scalp, face and scrotum, can be single or multiple, but rarely can occur in glabrous skin of palm and sole. They are known to result from progressive cystic ectasia of the infundibular portion of hair follicle but the pathogenesis in palmo-plantar epidermoid cyst differs that is traumatic sequestration of epidermal elements into dermis. Here, we report a case of 30-year-old female presented with complaints of swelling in her left sole. On examination a palpable firm swelling was noted just below the 2 web space left foot plantar region, on X-ray foot no osseous lesion or foreign body was detected. Swelling was excised and sent for histopathological examination which confirmed it as epidermoid cyst.
