Thyroid cancer is the most frequent endocrine neoplasm in the general population. Common risk factors include gender, radiation exposure, and genetic backgrounds. The association of papillary thyroid cancer and celiac disease has frequently been reported in the literature; however, the association of papillary thyroid cancer and thalassemia trait is rare. Likewise, the association of thalassemia major and celiac disease is also rare. We hereby report a unique case of papillary thyroid cancer in a patient with celiac disease and thalassemia trait.
We report the case of a 57-year-old woman who presented with local invasion of the anal canal by mucinous adenocarcinoma, the malignant transformation of a long-term preexisting retrorectal tailgut cyst. This progression is infrequent and justifies preemptive surgical treatment of retrorectal cysts.
