This study describes epithelioid glomus tumors, a rare variant with distinct cell morphology. These tumors, while appearing atypical, share characteristics with conventional glomus tumors and are successfully treated with surgical excision.

Area of Science:

  • Pathology
  • Oncology
  • Dermatology

Background:

  • Glomus tumors are typically composed of small, uniform cells.
  • An unusual histological variant, epithelioid glomus tumor, is presented.
  • This variant exhibits distinct cellular morphology compared to conventional glomus tumors.

Observation:

  • Epithelioid glomus tumors consist of large polygonal to spindle-shaped cells with abundant eosinophilic cytoplasm and irregular nuclei.
  • These cells possess both epithelioid and myoid qualities.
  • Cytological atypicality in epithelioid areas is attributed to degeneration or senescence, not neoplastic progression.

Findings:

  • Immunohistochemical and ultrastructural studies confirm smooth muscle derivation, identical to conventional glomus tumors.

  • The differential diagnosis for epithelioid glomus tumors includes benign and malignant epithelial and spindle-cell lesions.
  • Simple surgical excision was curative in all reported cases with follow-up.

    • Implications:

    • Recognition of epithelioid glomus tumors is crucial to avoid misdiagnosis with other neoplastic lesions.
    • Understanding the benign nature of cellular atypia aids in accurate diagnosis and patient management.
    • This report highlights a previously undescribed variant of glomus tumor, expanding diagnostic knowledge.
