Summary
Cervical malignant teratomas can mimic other conditions like hematomas, especially in young adults. Early consideration of teratoma is crucial for accurate diagnosis and timely treatment of this rare neck mass.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Post-pubertal teratomas are rare and can present as metastatic disease.
- Malignant teratomas may be overlooked due to varied presentations.
Observation:
- A 24-year-old male presented with a persistent neck mass initially suspected as a hematoma.
- Imaging revealed a large mass occluding the left internal jugular vein.
Findings:
- Surgical biopsy confirmed an immature testicular teratoma.
- Metastatic disease was identified in the inguinal region, lymph nodes, and abdomen.
Implications:
- Cervical teratoma should be considered in the differential diagnosis of neck masses in young adults.
- Prompt diagnosis and multimodal treatment, including chemotherapy, are essential for managing metastatic teratoma.
