Abstract: Foot pain and deformity occur as presenting feature in many of patients with rheumatoid arthritis (RA) and some of them leading to painful callosities. Epidermoid cysts are common benign subcutaneous lesions. These occur from penetration of epidermal cells into underlying dermal tissue. It characterized as these are slow-growing, raised round-oval, firm intradermal cysts. It is commonly seen in hairy regions of body like scalp, face and trunk, can be single or multiple, but rarely can occur in glabrous skin of palm and sole. Epidermal cysts occur from penetration of epidermal cells into underlying dermal tissue. Here, we report a case of 71-year-old woman with RA patient, presented with complaints of swelling in her left fore-sole. A palpable firm lesion was located just below the 1st metatarsophalangeal (MTP) joint of left foot plantar. At first, it was considered as painful callosities, but examined on CT and MRI, not osseous lesion, subcutaneous soft tissue mass was detected. We excised it and sent for histopathological examination which confirmed it as planter epidermoid cyst.
