Microscopic (histologic) description
  • Single cells, linear arrangements or aggregates of small, round / oval nevus cells with moderate pale / clear cytoplasm, round nuclei with fine chromatin, no prominent nucleoli or pleomorphism, usually within fibrous capsule and trabeculae, but also within nodal parenchyma (Am J Surg Pathol 2003;27:673) or surrounding a small vessel (Am J Surg Pathol 1996;20:834)

Differential diagnosis
  • Blue nevus: also spindled / dendritic cells with heavy pigmentation
  • Metastatic carcinoma or melanoma: usually not confined to capsule, atypia, mitotic figures, different immunostaining
  • Spitz nevus: larger cells with abundant eosinophilic cytoplasm, vesicular nuclei with prominent nucleoli
