Summary
A rare malignant proliferating trichilemmal tumour, initially misdiagnosed as a pilar cyst, was identified in an elderly man. Metastasis to the neck lymph nodes was confirmed, highlighting diagnostic challenges.
Area of Science:
- Dermatopathology
- Oncology
Background:
- Pilar cysts are common benign skin lesions.
- Malignant proliferating trichilemmal tumours (MPTT) are rare adnexal neoplasms.
Observation:
- An 86-year-old male presented with a gradually enlarging, painless mass on the jaw.
- Initial clinical diagnosis was pilar cyst.
- Histopathology revealed MPTT.
Findings:
- The MPTT was initially misdiagnosed.
- Four months post-diagnosis, metastatic MPTT was found in a left jugular lymph node.
Implications:
- MPTT can present insidiously and mimic benign lesions.
- Early detection and diagnosis are crucial for managing MPTT.
- This case underscores the importance of histopathological confirmation for jaw masses.
