Thyroidectomy for life threatening giant familial goitre

Area of Science:

• Endocrinology
• Genetics
• Surgical Oncology

Background:

• Investigates a family with a high prevalence of non-endemic goitre.
• Focuses on a case requiring urgent thyroidectomy for a giant multinodular goitre causing airway obstruction.

Observation:

• Family screening demonstrated a 100% incidence of nodular goitre in eight first-generation descendants.
• One first-generation descendant presented with hyperthyroidism.
• A euthyroid pattern was observed in 6 first-generation and 5 second-generation descendants.

Findings:

• The study identified a significant familial aggregation of nodular goitre.
• Dyshormonogenesis was ruled out as a cause in two first-generation descendants via the perchlorate discharge test.
• The genetic predisposition to multinodular goitre in this family is strongly suggested.

Implications:

• Highlights the importance of genetic screening in families with a history of goitre.
• Suggests potential genetic factors contributing to non-endemic multinodular goitre.
• Informs clinical management and genetic counseling for affected families.
