Castleman's disease presenting as a midline neck mass

Area of Science:

• Head and Neck Surgery
• Pediatric Pathology

Background:

• Castleman's disease is a rare lymphoproliferative disorder.
• Hyaline-vascular Castleman's disease is the most common subtype.

Observation:

• A 13-year-old girl presented with a painless submental neck mass.
• The mass was located in the midline of the submental region.

Findings:

• Excision biopsy confirmed the mass as hyaline-vascular Castleman's disease.
• Histopathological examination revealed characteristic features of the hyaline-vascular subtype.

Implications:

• Castleman's disease should be considered in the differential diagnosis of neck masses in children.
• Early diagnosis and surgical management are crucial for favorable outcomes.
