title: [A rare case of concurrent follicular and columnar cell variants of papillary thyroid carcinoma].
abstract: The paper describes a rare case of concurrent two different histological (follicular and columnar cell) variants of papillary carcinoma in one thyroid with columnar cell metastases to the lymph nodes and femoral bone. There are morphological features of and differences in BRAF status in the cells of two variants of papillary thyroid carcinoma.
