    Summary

    This study reports eight cases of glomus tumors in women aged 46-55, presenting with ear symptoms. Histochemical analysis revealed serotonin granules as a potential marker for these rare tumors.

    Area of Science:

    • Otolaryngology
    • Surgical Pathology
    • Oncology

    Context:

    • Glomus tumors, also known as chemodectomas, are rare neuroendocrine neoplasms.
    • These tumors can occur in the head and neck region, including the temporal bone, leading to various symptoms.

    Purpose:

    • To report eight cases of glomus tumors in women presenting with otological symptoms.
    • To investigate the histological and histochemical characteristics of these tumors.
    • To identify potential diagnostic markers for glomus tumors.

    Summary:

    • Eight female patients (46-55 years) with glomus tumors experienced tinnitus, hearing loss, and localized pain.
    • Surgical intervention was performed for all patients, with one requiring reoperation.
    • Histological examination revealed angiomatous structures with fibrosis, and an alveolar variant was noted.
    • Immunoperoxidase staining identified serotonin granules, suggesting they may be an aspecific marker for glomus tumors.

    Impact:

    • Highlights the clinical presentation and diagnostic challenges of glomus tumors in the ear.
    • Provides insights into the histochemical features, particularly the presence of serotonin granules.
    • Contributes to the understanding of glomus tumor pathology and potential diagnostic markers.
