Summary
A rare, painful intravenous glomus tumor in a 79-year-old woman
Area of Science:
- Vascular Pathology
- Surgical Oncology
Background:
- Glomus tumors are typically benign neoplasms originating from glomus bodies.
- Intravascular glomus tumors are exceptionally rare, with only a few prior reports.
- This case presents a massive intravenous glomus tumor, a presentation not previously documented.
Observation:
- A 79-year-old female presented with a painful mass in her right forearm.
- A large (14 cm) tumor was found originating from and protruding into a vein lumen.
- Immunohistochemistry revealed vimentin, alpha-smooth-muscle actin, and collagen IV expression.
Findings:
- The tumor was completely excised, with no evidence of recurrence or metastasis.
- Intravascular glomus tumors, though rare, show a predilection for the forearm in adults (average age 61.5).
- Despite its size and intravascular location, the tumor exhibited non-aggressive behavior.
Implications:
- Pathologists should recognize this rare variant to prevent misdiagnosis.
- Awareness of intravenous glomus tumors aids in appropriate surgical management.
- This case expands the understanding of glomus tumor presentation and behavior.
