Summary
A rare zygomatic mass in a man with facial trauma was initially thought to be a fracture callus. However, elevated prostate-specific antigen (PSA) levels and biopsy confirmed metastatic prostate adenocarcinoma.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Zygomatic arch masses are uncommon.
- Facial trauma can cause bone changes, mimicking other conditions.
Observation:
- A 52-year-old man presented with a zygomatic arch mass following facial trauma.
- Computed tomography (CT) scans suggested fracture callus formation.
- Elevated prostate-specific antigen (PSA) levels were noted (62.3 ng/mL).
Findings:
- Prostate biopsy revealed adenocarcinoma (Gleason sum, 3 + 4 = 7).
- Discrepancies between clinical presentation, imaging, and laboratory data suggested an alternative diagnosis.
- The zygomatic mass was ultimately identified as a metastasis from prostate cancer.
Implications:
- This case highlights the importance of considering metastatic disease in patients with seemingly benign bone lesions.
- Unexplained laboratory abnormalities, such as elevated PSA, warrant thorough investigation.
- Multidisciplinary evaluation is crucial for accurate diagnosis in complex cases involving bone masses.
