Autopsy case of aortic dissection after transcatheter aortic valve implantation (TAVI).

Aortic dissection is one of the severe but rare vascular complications arising from transcatheter aortic valve implantation (TAVI). This paper presents an autopsy case of an 81-year-old male patient with delayed aortic dissection with underlying haemorrhages and acute inflammation 3 years after TAVI.

Detection of ALK-positive non-small-cell lung cancers on cytological specimens: high accuracy of immunocytochemistry with the 5A4 clone.

Introduction: Lung cancer is often diagnosed by cytology, necessitating predictive molecular marker analyses on cytological specimens. The gold standard for detection of predictive anaplastic lymphoma kinase (ALK)-rearrangements is fluorescence in situ hybridization (FISH), but FISH is both expensive and often challenging to interpret. The aim of our study was to investigate the accuracy of ALK immunocytochemistry (ICC) on cytological specimens of non-small-cell lung cancers (NSCLCs).

A cavernous hemangioma of the thyroid gland: First documentation by ultrasound of a rare pathology.

Hemangioma of the thyroid gland is an extremely rare condition. We report a case of a primary cavernous hemangioma in the left lobe of the thyroid gland in an 84-year-old woman. Ultrasound examination of the lesion showed an inhomogeneous and hypoechoic nodule that was well demarcated from the rest of the left lobe and hypovascular on color Doppler ultrasound.

[Ultrasound and cytology: ultrasound-controlled fine needle puncture].

Ultrasound guided fine needle aspiration biopsy has shown to be a safe and cost-effective method for diagnostic assessment in complex and nonpalpable lesions. Experience in aspiration technique, smearing and fixation of the sampled probe are prerequisites for a good diagnostic yield.
