There has been no individual ultrasound feature of having high accuracy for diagnosis of thyroid malignancy. In this study, we aimed to establish feature-oriented criteria to characterize benign thyroid nodules that do not require ultrasound (US)-guided fine needle aspiration (FNA). We reviewed 374 patients with thyroid nodules who had undergone ...

Early diagnosis and rapid surgical excision are essential for improving the prognosis of melanoma patients. Reflectance confocal microscopy has been validated as a feasible procedure for in vivo diagnosis of melanoma but cannot be used to measure tumour thickness. However, ultrasonography and optical coherence tomography may allow melanoma thickness to ...

Abstract Conclusion: The accuracy and sensitivity of fine-needle aspiration cytology (FNAC) in this analysis were not satisfactory, and the false-negative rate seemed to be higher than for parotid tumours. The possibility of low-grade malignancy should be considered in the surgical treatment of accessory parotid gland (APG) tumours, even if the ...

Collection of abdominal subcutaneous adipose tissue (SAT) for research testing is traditionally performed using punch biopsy or needle-aspiration techniques, yielding small amounts of very superficial SAT (100-500 milligrams). Although liposuction techniques can be used to obtain large amounts of SAT, these approaches can compromise the integrity of the adipose tissue. ...

Clinical differentiation between a nodular basal cell carcinoma (nBCC) and a benign intradermal nevus can be difficult. Even with additional dermoscopic evaluation, a correct diagnosis may be difficult. Currently, histopathological examination of a biopsy is the gold standard to differentiate between these lesions. However, this is an invasive technique and ...

Urine cytology is routinely used for early diagnosis and monitoring of patients with hematuria or a history of urothelial carcinoma, but its clinical utility is greatly diminished by a high frequency of "atypical" specimens, reportedly around 20% in the literature. We compared our results with double-stained urine cytology specimens (papanicolaou ...

Despite the classic tetrad of clinical features that typify it, narcolepsy remains much under-diagnosed, in part, because of the wide spectrum of clinical phenotypes, but also because of its insidious onset, usually in a young person. The median time to diagnosis from first symptoms remains very long, around 10 years in ...

Although partial epilepsy with structural lesions on MRI (lesional epilepsy) is less favorably responsive to antiepileptics than those without structural lesions on MRI, the response to antiepileptics in lesional epilepsy is a heterogeneous condition. There is growing evidence that the extent of epileptic network beyond the visible lesion on MRI ...

Dysplasia represents a pre-neoplastic status in multi-step colon carcinogenesis. Whereas laborious preparation of thin sections is required for its diagnosis, we here show that newly defined aberrant crypt foci (ACF) simply mark the majority of the dysplasia on the whole colon. Specifically, de-coloring of the azoxymethane-treated rat colon after scoring ...

The WHO categorizes pituitary tumours as typical adenomas, atypical adenomas and pituitary carcinomas, with typical adenomas constituting the major class. However, the WHO classification does not provide an accurate correlation between histopathological findings and clinical behaviour. Tumours lacking typical histological features are classified as atypical, but not all are clinically ...

Lipomatous tumours are rare in the head and neck region. Their biological behaviour varies greatly, from absolutely benign to histologically benign but locally infiltrative and, finally, invasive with metastatic potential. Each lipomatous tumour has to be treated accordingly. It is of paramount importance before eventual surgery is planned to perform ...
