[Multiple generalized glomus tumors. Morphologic and biochemical findings].

W C Marsch, T M Ernst, M Artuc

    Zeitschrift Fur Hautkrankheiten
    |June 15, 1986

    Summary

    This study details a patient with numerous glomus tumors and a capillary hemangioma. Painful glomus tumors exhibited increased glomus cells, suggesting a link to adrenergic innervation.

    Area of Science:

    • Dermatology
    • Pathology
    • Vascular Biology

    Background:

    • Glomus tumors are benign neoplasms originating from glomus bodies, typically found in the digits.
    • Multiple glomus tumors can occur systemically, posing diagnostic and therapeutic challenges.
    • Congenital capillary hemangiomas, or "strawberry marks," are common vascular malformations present at birth.

    Observation:

    • A 54-year-old female presented with approximately 150 generalized glomus tumors, developing since age 23.
    • The patient also had a persistent congenital capillary hemangioma.
    • Painful glomus tumors demonstrated a higher density of glomus cells compared to asymptomatic ones.

    Findings:

    • Histological examination confirmed glomus cells within the vessel walls of the tumors.
    • Significant levels of Dopa were detected in the glomus tumor tissue.
    • The presence of Dopa supports the hypothesis of adrenergic efferent nerve innervation in glomus tumors.

    Implications:

    • Understanding the cellular composition and innervation of glomus tumors is crucial for pain management.
    • This case highlights the potential association between glomus tumors and congenital vascular anomalies.
    • Further research into the neuro-vascular interactions in glomus tumors may reveal novel therapeutic targets.
