Sellar glomus tumors, a rare sellar region neoplasm, present challenges in diagnosis. This report details a third case, highlighting its glomangioma characteristics and differential diagnostic considerations.

Area of Science:

  • Neuro-oncology
  • Endocrinology
  • Pathology

Background:

  • Glomus tumors are rare neoplasms typically found in the skin or soft tissues.
  • Sellar region glomus tumors are exceptionally rare, with only two prior cases documented in medical literature.
  • Pituitary adenomas are the most common sellar region tumors, often presenting with similar radiographic and gross appearances.

Observation:

  • A 72-year-old male presented with a sellar region mass.
  • Radiographic and gross examination revealed a lesion mimicking a pituitary adenoma.
  • Microscopic analysis showed a tumor composed of epithelioid cells surrounding vascular channels, with indistinct borders and monotonous nuclei.

Findings:

  • Histological and immunohistochemical analyses confirmed the sellar tumor as a glomangioma.

  • This case represents the third documented instance of a glomus tumor in the sellar region.
  • The findings underscore the importance of considering rare tumor types in the sellar differential diagnosis.

    • Implications:

    • Accurate diagnosis of sellar glomus tumors requires careful histopathological and immunohistochemical evaluation.
    • Recognition of this rare entity is crucial for appropriate clinical management and patient outcomes.
    • Further research into the pathogenesis and behavior of sellar glomus tumors is warranted.
