Abstract

Plantar vein thrombosis, rarely-reported disease, is usually accompanied by pain and tenderness in the plantar region and should be differentiated from other dermatological conditions causing plantar pain, such as hemorrhagic corn/callus, plantar epidermal cyst, verruca, or plantar fibromatosis. A 52-year-old man presented with a violaceous tender subcutaneous nodule overlying a hyperkeratotic plaque on his sole. Initially, he thought it was a corn and applied keratolytic agents, which failed to work. Sonography revealed a well-demarcated mass with increased peripheral vascularity. His pain was relieved after a complete wide excision, which confirmed the mass to be plantar vein thrombosis after histopathological examination.
