The sensitivity of endocervical curettage (ECC) can be suboptimal because of limited epithelial tissue. The false-negative rate for ECC in patients with cervical intraepithelial neoplasia involving the endocervical canal has been reported to be 45%. ECC samples are transported to pathology in formalin- or saline-filled containers; this fluid is discarded ...

Vascular anomalies can be subdivided into vascular tumours and vascular malformations (VMs). While most VMs are present at birth and do not exhibit significant postnatal growth, vascular tumours are characterized by their dynamics of growth and (sometimes) spontaneous regression. This review focuses on benign vascular tumours other than infantile haemangiomas ...

The classification system for vascular anomalies now used by experts worldwide comprises two distinct disease entities that differ in their biologic and pathologic features: vascular tumors and vascular malformations. Vascular tumors include infantile and congenital hemangiomas, tufted angiomas, and kaposiform hemangioendotheliomas. Infantile hemangiomas, the most common vascular anomaly, generally have ...

Thyroid nodules that exhibit focal uptake of fluorine-18 ((18)F)-fluorodeoxyglucose (FDG) are relatively frequent. Although the clinical features and associated mechanisms of FDG-avid lesions in both thyroid cancer and cytologically indeterminate nodules have been extensively studied, not much information is available on benign nodules. Therefore, in this retrospective study, the clinical, ...

Sciatic nerve mass-like enlargement caused by peripheral nerve sheath tumors or neurocutaneous syndromes such as neurofibromatosis or schwannomatosis has been widely reported. Other causes of enlargement, such as from perineuroma, fibromatosis, neurolymphoma, amyloidosis, endometriosis, intraneural ganglion cyst, Charcot-Marie-Tooth disease, and chronic inflammatory demyelinating polyneuropathy are relatively rare. High-resolution magnetic resonance ...

Extradural spinal meningiomas are rare. Our understanding of purely extradural spinal meningiomas is incomplete because most reports rarely differentiate purely extradural meningiomas from extradural meningiomas with an intradural component. Occasionally, reports have described involvement of the adjacent nerve root, but there has never been a description of an extradural meningioma ...
