Description

A 60-year-old woman presented with a cutaneous nodule with tenderness on her right heel. She had first noticed it when approximately 30 years old, but left it without treatment. The nodule grew larger, and the tenderness worsened over the three years prior to presentation. At presentation, she had an elastic, hard, partially hyperkeratotic, dome-shaped nodule measuring 26×22×11mm in size on the heel. The nodule was excised under local anesthesia. No recurrence has occurred so far. Histopathology of the nodule showed a clearly demarcated eosinophilic portion comprised of proliferating spindle-shaped cells. The spindle cells were arranged concentrically around the vessels in the nodule and were positive for alpha SMA, and stained in red with Masson's trichrome staining. Small calcified nests surrounded by collagen fiber were scattered within the nodule. Thus the patient was diagnosed with angioleiomyoma involving calcification. Although such tumors are usually painful, calcification over time and a relatively high pain threshold of the heel may have resulted in the present case experiencing no pain.Skin Research, 14: 183-187, 2015
