Anaplastic transformation is often reported in primary lesions, but is rarely found in metastatic lesions from Differentiated Thyroid Carcinoma (DTC).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Presentation of case:<\/jats:title>\n                    <jats:p>This case report reports a unique tumor process where a 70-year-old woman had a metastatic lesion in the Mandible from PTC which transformed into ATC with histological features resembling squamous cell carcinoma-type. Immunohistochemical examination was able to prove that the lesion in the Mandible is a type of undifferentiated Thyroid carcinoma (anaplastic) with a squamous pattern originating from PTC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion:<\/jats:title>\n                    <jats:p>This type of tumor with histological variant images that resemble other types of tumors is a challenge for diagnosis and appropriate management, so understanding the variants of this type of ATC is important for better management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Although rare, anaplastic transformation can occur in metastatic sites of PTC.
