A wide variety of tissues derived from the three germ layers are seen in ovarian teratomas. Microscopically, the most commonly seen tissues are epidermis, skin adnexa, and neural tissues. Thyroid tissue is present in 10% of ovarian mature cystic teratomas. In this case, report, we present a rare case of papillary microcarcinoma derived in the ovarian teratoma and Hashimoto's thyroiditis with the normal level of serum thyroid hormones, which is normal but positive serum antithyroid peroxidase antibodies.
Granular cell tumors (GCTs) are extremely rare neoplasms of the bladder. In the literature, there are only a few reported cases. We present a GCT case with clinical, radiological, histomorphological, immünohisto-chemical findings and its differential diagnosis.
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.
