It is one of the fastest growing cancer types with over 20,000 new cases a year. Papillary thyroid cancer, which is the most common type of thyroid cancer, makes up about 80% of all cases of thyroid cancer. The RAI is absorbed through digestion and circulated throughout the body in the bloodstream. Surgical excision is a golden standard in the treatment of papillary lesions and is recommended if the core needle biopsy shows atypia or invasion and in the presence of imaging-histological discordance. As a result, pathological and clinical evaluation is somewhat problematic. There are no evidence-based guidelines for the treatment of EPC. These tumors lack the myoepithelial cell layer (MCL) within the papillae or at the periphery of the tumor with areas showing stromal invasion or invasion into lymphovascular spaces. 1490 CASE SERIES Encapsulated papillary carcinoma (EPC) of breast: A clinical, pathological and immunohistochemical analysis of eight cases Naima Tariq, Nadira Mamoon, Mariam Usman, Zafar Ali, Imran Nazir Abstract but the demonstration of lack of myoepithelial layer at the Encapsulated papillary carcinoma (EPC) is a rare low grade lesion's periphery and the report of lung metastasis in .

Inflammatory breast cancer (IBC) is a rare type of breast cancer often starts in the soft tissues of the breast and causes the lymph vessels in the skin of the breast to become blocked. Encapsulated papillary carcinoma (EPC) is an interesting subgroup of breast papillary tumours. The size of the tumor ranges from 1-10 cm [16]. Treatment after surgery depends on the stage of the cancer: Radioactive iodine (RAI) treatment is sometimes used after thyroidectomy for early stage cancers (T1 or T2), but the cure rate with surgery alone is excellent.

Myoepithelial cells are present neither in the papillae of IPC nor at the periphery, in contrast to papillary ductal carcinoma in situ (DCIS), in which there are MECs at the periphery of involved spaces. Encapsulated papillary carcinoma (EPC) was described for the first time in 1969 as a papillary entity arising from the ductal-lobular system, developing in a cyst, and surrounded by a fibrous capsule. Displaying low-grade monomorphic nuclei at 40x. WHO describes "frank invasive carcinoma" for this histology as "neoplastic epithelial elements infiltrate beyond the fibrous capsule of encapsulated papillary carcinomas."
