Summary
Adenoid cystic carcinoma, a rare head and neck tumor, can present on the skin. This case highlights a late lymphatic metastasis, emphasizing the need for further research into optimal treatments.
Area of Science:
- Oncology
- Dermatology
- Head and Neck Surgery
Background:
- Adenoid cystic carcinoma (ACC) is an uncommon malignancy primarily affecting salivary glands but can occur in the skin.
- While metastases are rare, ACC has a significant recurrence rate, with 50% of cases relapsing.
Observation:
- A 65-year-old male presented with an upper lip lesion diagnosed as ACC.
- Following initial resection and radiotherapy, a lymphatic metastasis was detected in the neck 10 years later.
Findings:
- Primary cutaneous adenoid cystic carcinoma is rare.
- Treatment involves extensive local excision with clear margins.
- Radiotherapy is not curative and is best suited for palliative care.
Implications:
- This case underscores the potential for late lymphatic metastasis in cutaneous ACC.
- Multicenter, prospective studies are crucial to establish optimal treatment protocols, particularly adjuvant therapies.
- Further research is needed to improve outcomes for this rare cancer.
