    Benign nevus cell nevi in lymph nodes were studied. Morphologic similarities suggest these are actually glomus cell clusters, not nevus cells, potentially related to glomangiomas.

    Area of Science:

    • Surgical pathology
    • Histopathology
    • Cell biology

    Context:

    • Lymph nodes are critical components of the immune system.
    • Benign nevus cell nevi are typically found in the skin.
    • The presence of unusual cell clusters within lymph nodes requires careful evaluation.

    Purpose:

    • To investigate the nature of cell clusters described as benign nevus cell nevi in lymph nodes.
    • To differentiate these cells from true nevus cells using light and electron microscopy.
    • To determine the potential origin and classification of these enigmatic lymph node findings.

    Summary:

    • Nine lymph nodes with alleged benign nevus cell nevi were examined. Light and electron microscopy revealed cell clusters (35-645 μm) in the capsule or cortex, more common in older patients. Cytologic identification was unclear, with no evidence of nevus cells.

  • The cells exhibited significant morphologic similarity to glomus cells and were often located near blood vessels.
  • The study proposes these clusters are hamartomas associated with glomangiomas, reclassifying them as glomus cell clusters.

    • Impact:

    • This research reclassifies a previously misunderstood lymph node finding.
    • It provides a new perspective on lymph node pathology, distinguishing nevus-like lesions from glomus cell-related hamartomas.
    • The findings contribute to a more accurate diagnosis and understanding of benign vascular-related proliferations within lymph nodes.
