Thyroglossal duct cyst
Microscopic description
The sections show a large cystic structure filled with bland hyaline material that is lined by a squamoid epithelium. Focally, a smaller, microscopic, cyst has respiratory epithelium with cilia. Surrounding the cysts are normal fibro-adipose tissue, fragments of skeletal muscle, normal thyroid tissue and sebaceous glands. There is focal granulomatous inflammation associated with the wall of the large cyst. There is normal bone with unremarkable bone marrow, that has all three main lineages and scant adipose tissue. One small benign lymph node is present.
Final diagnosis
Bone and soft tissue, neck, excision - Thyroglossal duct cyst.
Branchial cleft remnant
Microscopic
The sections show normal skin and benign cartilage, skeletal muscle, white adipose tissue and brown adipose tissue. No cystic space is identified. There is no evidence of inflammation and no evidence of malignancy.
Final diagnosis
Soft tissue, left neck, excision - consistent with branchial cleft remnant
