A clinical case of papillary thyroid cancer associated with a PTEN gene defect

Abstract
The incidence of malignant neoplasms associated with solitary thyroid nodules is higher in children than in adults. The diagnosis of nodular thyroid pathology in pediatric practice clearly requires particular attention. Clinical history should include an assessment of risk factors for malignant tumors and a family history. Thyroid tumors are observed in certain syndromes, such as Carney complex, familial adenomatous polyposis, and Cowden, DICER1, Werner, McCune–Albright, and Li–Fraumeni syndromes. This article presents a case of a highly differentiated thyroid tumor diagnosed in a 15-year-old boy. The distinct morphological features of the postoperative tissue indicated the need for molecular genetic testing in this patient. Genetic analysis revealed a mutation in a gene responsible for regulating cellular apoptosis, suggesting a diagnosis of Cowden syndrome in the patient. Cowden syndrome is a rare disorder associated with a mutation in the PTEN gene, characterized by multiple hamartomas in various organs. PTEN gene mutations lead to lesions in the skin, mucous membranes, thyroid gland, and fibrocystic mastopathy.
