- branchial cleft cyst (BCC)

  • The most-common variety of solitary cervical cystic lesion is the branchial cleft cyst (BCC), which can become malignant.

- cervical cystic squamous cell carcinoma

  • The majority of previously suspected BCCCs were actually metastatic cystic lymph nodes; misdiagnosis can occur due to the absence of long-term follow-up.

- solitary metastatic cystic lymph node
- * Thus, solitary metastatic cystic lymph nodes, from carcinomas of the upper aerodigestive tract, are difficult to differentiate from BCCCs, especially in patients more than 40 years of age.

  • The proportion of metastatic cystic SCCs initially diagnosed as BCCs, or BCCCs, ranges between 11% and 21%.
  • Metastatic cystic SCCs in the upper lateral neck are easily mistaken for BCCCs if the primary site of the carcinoma is not detected.
  • The majority of metastatic cervical lymph nodes in head-and-neck squamous cell carcinomas (HNSCCs) are solid masses. However, between 33% and 62% of cases are cystic metastatic squamous cell carcinomas (SCC).
  • The challenge, therefore, is to distinguish BCCC from occult metastatic cystic SCC, and to identify the primary site of metastatic cystic SCC in the head and neck.
