title: Anaplastic thyroid carcinoma with diffuse thoracic skin metastasis: A case report.
abstract: Anaplastic thyroid carcinoma is a significantly fatal endocrine neoplasm, with an average survival time of 4-12 months following diagnosis. The present study reports the case of a 57-year-old male patient who presented to the Bağcılar Training and Research Hospital (Istanbul, Turkey) due to swelling in the neck and difficulty swallowing. The jugular mass biopsy results were consistent with a diagnosis of anaplastic thyroid cancer. The patient was regarded to have advanced-stage subcarinal, paratracheal, aortopulmonary, trancheobronchial and mediastinal lymphadenopathies and exhibited a good prognosis following chemotherapy. However, the patient succumbed one month later due to the emergence of diffuse skin lesions. The histopathological and immunohistochemical assessment of the skin biopsy displayed the characteristics of the underlying thyroid carcinoma.
