Malignant branchioma--a further insight

Area of Science:

• Head and Neck Oncology
• Surgical Pathology
• Branchial Cleft Anomalies

Background:

• Branchial cleft cysts are common congenital neck masses, but malignant transformation is exceedingly rare.
• Malignant branchioma, a carcinoma arising from a branchial cleft cyst, presents diagnostic and therapeutic challenges.

Observation:

• Two cases of solitary cystic neck masses, initially suspected as typical branchial cysts, were histologically confirmed as malignant branchioma.
• Both patients underwent pre-operative radiotherapy and ipsilateral radical neck dissection.

Findings:

• The first patient developed tonsillar carcinoma and died 3.5 years post-diagnosis.
• The second patient remains disease-free 4 years after diagnosis, with prophylactic oropharyngeal irradiation.
• Treatment strategies and the nature of malignant branchioma are discussed.

Implications:

• This report highlights the importance of thorough histological examination for suspected branchial cysts.
• Aggressive multimodal treatment may improve survival rates for malignant branchioma.
• Further research is needed to elucidate the pathogenesis and optimize management protocols for this rare malignancy.
