Summary
A symptomatic Rathke cleft cyst in a 35-year-old woman contained xanthomatous cells. Its lining epithelium resembled third ventricle colloid cysts, with minor pituitary cell presence.
Area of Science:
- Neuropathology
- Endocrinology
- Neurosurgery
Background:
- Rathke cleft cysts (RCCs) are common suprasellar嚢胞.
- Symptomatic RCCs can cause mass effect and hormonal dysfunction.
- Xanthomatous changes in RCCs are rare but documented.
Observation:
- A 35-year-old woman presented with symptoms attributed to a suprasellar Rathke cleft cyst.
- Histopathological examination revealed extensive xanthomatous cells within the cyst wall and contents.
- Immunohistochemical and ultrastructural analysis showed the cyst lining epithelium was largely indistinguishable from colloid cysts of the third ventricle.
Findings:
- The Rathke cleft cyst demonstrated significant xanthomatous infiltration.
- The epithelial lining shared key features with third ventricle colloid cysts.
- A small population of pituitary hormone-positive cells was noted within the cyst lining.
Implications:
- This case highlights the diverse histopathological presentations of Rathke cleft cysts.
- Understanding the cellular composition is crucial for accurate diagnosis and management of suprasellar lesions.
- The findings suggest a potential shared developmental or cellular origin pathway between RCCs and colloid cysts, warranting further investigation.
