Squamous Cell Differentiation in Metastatic Papillary Thyroid Carcinoma: Metaplastic
Squamous cell differentiation (SCD) may occur in papillary thyroid carcinoma (PTC) only at metastatic sites. We have studied cytokeratin CK5/6 and P63 along with TTF1 (thyroid transcription factor 1) and B-Raf (V-Raf murine sarcoma viral oncogene homolog B1) immunohistochemical expression in neck lymph node metastases of thyroid PTC showing SCD. The patient (21-years) presented wit...

متن کاملAtypical lipomatous tumor with unusual extensive metaplastic ossification
The presence of metaplastic ossification within atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS) is a rare occurrence. When present, bone formation is most often found in association with a dedifferentiated component arising within the primary tumor. It is important for the radiologist not only to recognize the differential diagnosis of a calcified or ossified soft tissue m...
متن کاملPrimary non-gestational uterine cervical choriocarcinoma with metaplastic transformation from squamous cells.
BACKGROUND Primary non-gestational uterine cervical choriocarcinoma is very unusual and although it has been hypothesized that it can arise by metaplastic transformation of cervical epithelium, solid evidence has been lacking. CASE Primary non-gestational uterine cervical choriocarcinoma was diagnosed in a 47-year-old, woman undergoing tubal resection 17 years previously. A histologically- an...
متن کامل"atypical squamous cells of undetermined significance: a cytohistologic study"
