Summary
This case report details a rare splenic hamartoma, a complex vascular spleen lesion. The findings suggest it may represent Sclerosing Angiomatoid Nodular Transformation (SANT) of the spleen.
Area of Science:
- Pathology
- Vascular Lesions
- Spleen Imaging
Background:
- Splenic hamartomas are rare, complex vascular lesions with ongoing classification debates.
- Recent reinterpretations highlight confusion regarding definition and histogenesis.
Observation:
- A young woman presented with an incidentally discovered splenic nodule on ultrasound.
- Pathological examination revealed a large, well-demarcated splenic mass (10 cm).
- Histology showed an angiomatoid lobular-nodular pattern with fibrosclerotic stroma and calcification.
Findings:
- Immunohistochemistry identified diverse vascular structures: capillaries, splenic venous sinuses, and small veins.
- The complex vascular profile supports a diagnosis of splenic hamartoma with a lobular-nodular pattern.
- This presentation aligns with Sclerosing Angiomatoid Nodular Transformation (SANT) of the spleen.
Implications:
- Understanding the varied morphology of splenic hamartomas is crucial for accurate diagnosis.
- Distinguishing splenic hamartoma from other splenic lesions like hemangiomas and inflammatory pseudotumors is important.
- This case contributes to the spectrum of splenic vascular lesions and their classification.
