Specimen A and B present with similar microscopic findings- The lesion
consisted of an intradermal nodule composed of clear cells in a
glandular configuration with a prominent vascular stroma. Multiple
erythrocytes were noted (Figure 3 ). Pancytokeratin, vimentin,
and EMA stains were positive (Figure 4 ). CD10 was focally
