Summary
This study presents a rare case of a trichilemmal cyst (TC) extensively involving the skull base. Histopathology confirmed it as a typical cutaneous TC, despite its unusual location.
Area of Science:
- Dermatopathology
- Neurosurgery
- Head and Neck Surgery
Background:
- Trichilemmal cysts (TCs) are rare tumors originating from the outer root sheath of hair follicles.
- TCs typically occur on the scalp and have not been previously reported to involve the skull base.
Observation:
- A unique case of a TC extensively involving the skull base, including the temporal-infratemporal fossae, orbit, paranasal sinuses, and clivus, is presented.
- Clinical, radiological, operative, and pathological features of this extensive TC are detailed.
Findings:
- Multilocular cysts filled with keratinized material were identified.
- Histopathological examination revealed features consistent with a typical cutaneous trichilemmal cyst.
Implications:
- This case demonstrates that cutaneous trichilemmal cysts can extensively involve the skull base.
- Understanding the potential for TCs to affect the skull base is crucial for accurate diagnosis and surgical planning.
