Summary
A novel glomangioma variant, the acquired solitary plaque-like telangiectatic glomangioma, is described. This distinctive cutaneous glomus tumor presents as a painful, telangiectatic plaque, confirmed by histopathology and immunohistochemistry.
Area of Science:
- Dermatopathology
- Vascular Tumors
- Oncology
Background:
- Glomangiomas are benign vascular tumors originating from glomus bodies.
- Cutaneous glomus tumors typically present as small, painful red-blue papules or nodules.
- Clinicopathological variants of glomus tumors expand our understanding of their diverse presentations.
Observation:
- A 33-year-old woman presented with a 3-year history of a painful, solitary, telangiectatic plaque on her right shoulder.
- The lesion's clinical appearance was atypical for a common glomus tumor.
- Histopathological examination revealed ectatic vascular lumina within the dermis.
Findings:
- Glomus cells were identified surrounding the ectatic vascular lumina.
- Immunohistochemical and ultrastructural studies confirmed the glomus cell origin.
- The findings support the classification of this entity as a new variant: acquired solitary plaque-like telangiectatic glomangioma.
Implications:
- This case expands the spectrum of glomus tumor presentations.
- Recognition of this variant is crucial for accurate diagnosis and appropriate clinical management.
- Further research may elucidate the specific pathogenesis and behavior of this distinct glomangioma subtype.
