Summary
Giant cell angiofibroma (GCA), a rare tumor, typically occurs in the orbit. This report details an unusual GCA case presenting as a solitary scalp nodule, highlighting its diverse potential locations.
Area of Science:
- Dermatopathology
- Surgical Pathology
- Oncology
Background:
- Giant cell angiofibroma (GCA) is a rare mesenchymal neoplasm.
- Initially described in the orbit, GCA can occur in extratumoral locations.
- Recognizing GCA's varied presentations is crucial for accurate diagnosis.
Observation:
- A 32-year-old female presented with a painless, solitary nodule on the occipital scalp.
- The lesion exhibited a patternless proliferation of spindle cells with pseudovascular spaces.
- Distinctive floret-like multinucleated giant cells were a key morphological feature.
Findings:
- Histopathological examination confirmed the diagnosis of giant cell angiofibroma.
- The occipital scalp represents an extremely rare site for GCA.
- The tumor displayed characteristic vascularity and cellular morphology.
Implications:
- This case expands the known anatomical distribution of giant cell angiofibroma.
- It underscores the importance of considering GCA in the differential diagnosis of scalp nodules.
- Further research may elucidate GCA's behavior in extratumoral sites.
