Summary
Amygdaloid cysts, a common second branchial cleft anomaly, present as neck swellings. Surgical excision is the standard treatment for these benign tumors.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Developmental Biology
Background:
- Amygdaloid cysts are benign dysembryological tumors arising from persistent cervical sinus remnants.
- They constitute a significant portion of second branchial cleft anomalies, ranging from 6.1% to 85.2%.
Observation:
- These cysts manifest as laterocervical swellings, typically located anterior to the sternocleidomastoid muscle.
- Imaging modalities like ultrasound and CT confirm their cystic nature.
- A case report details a 33-year-old male with a large, asymptomatic right laterocervical swelling.
Findings:
- Histopathological examination confirmed the diagnosis of an amygdaloid cyst, with no evidence of malignancy.
- The cyst was a huge, right laterocervical swelling evolving over 16 months.
Implications:
- Understanding the anatomo-clinical features is crucial for accurate diagnosis and management.
- Surgical excision remains the primary therapeutic approach for amygdaloid cysts.
- This case highlights the importance of considering branchial anomalies in the differential diagnosis of neck masses.

324
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
