Thyroid gland papillary carcinoma with fibromatosis-like stroma: Case report

Papillary carcinoma of the thyroid may show a variable degree of fibrosis o f the stroma, but proliferation of the stromal fibroblasts mimicking fibrom atosis is rare. There appears to be a new variant of papillary carcinoma of the thyroid associated with exuberant proliferation of the fibroblasts res embling fibromatosis. We present one such case in a 50 year old woman and s uccinctly reviewed the relevant literature of this rare variant. The necess ity of a diligent search for a papillary carcinoma in thyroid gland which s hows a proliferative fibrous lesion is stressed.
