Occult invasion of sternothyroid muscle occurred in 16% of DTC in this series. Excision of the muscle en bloc with thyroidectomy, particularly in larger tumors, may confer benefit in accurately staging the disease, encompassing occult ETE and achieving clear microscopic margins.
We present a case of a rare liver neoplasm – Ossifyimg malignant mixed epithelial and stromal tumor. This entity has well-delineated morphological and immunohistochemical features, and so can be easily diagnosed, even with core biopsy tissue. Our patient was a middle-aged male, which is unheard of in the literature of this disease. He had a bad recurrence of the disease after surgical removal of the tumor, unlike the previously reported cases with the same diagnosis, where the patients lived for almost a decade after surgery without recurrence. This neoplasticdisease can thus take a destructive course, and a change in treatment methods such as neoadjuvant or adjuvant chemotherapy should be thought of, to make it more beneficial and effective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
