A 45-year-old woman, controlled diabetic and hypertensive, presented with a complaint of a painless nodule on her left shin for the last three months which had gradually increased in size since she noticed it. There was no history of exposure to sunlight, itching, or trauma. Her garments had always covered her thighs and legs. On examination, there was a single, 3.8 × 2.9 × 1.4 cm, non-tender, purplish-pink, nonulcerative, nodular lesion over the pretibial region of the middle one-third of the left leg. There was a rim of 4–6 mm skin discoloration all around [Figure 1]. The lesion was freely mobile over the underlying bone. There were no satellite lesions and no lymphadenopathy in the popliteal fossa and groin. The rest of the leg appeared normal with no functional or distal neurovascular deficit. Routine blood test results were within normal range while radiologic investigations revealed no signs suggestive of bony invasion.
