The nodule had a plexiform architecture (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>B) and did not make contact with the epidermis. Some cells had an epithelioid appearance with abundant eosinophilic cytoplasm, blurred cell borders, vesicular nuclei, and inconspicuous nucleoli. Other cells were delicate and spindle-shaped, with hyperchromatic nuclei. No pleomorphism, mitoses, or necrosis were observed. The stroma was myxoid with areas of collagen appearance (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a><span class="elsevierStyleHsp" style=""></span>C).

MiTF1, S100A6, and PGP9.5 have been strongly positive in those cases in which they were studied.
