Significance of bizarre cells in cervical screening liquid-based cytology: A prospective study of 15 cases.

Objective: The aim of this study was to assess the significance of bizarre cells (cells of squamous origin with a superficial squamous cell-type cytoplasm and characterised by multinucleation that produces bizarre nuclear shapes) in liquid-based cytology (LBC) Papanicoaou (pap) smears with clinical and histological follow-up correlation.

Methods: Fifteen patients, all with LBC samples containing bizarre cells, were identified in routine ThinPrep LBC workload. HPV testing was performed in each case using residual LBC material.

[Sarcomatous chromophobe cell renal carcinoma. 2 case reports].

Chromophobe cell renal carcinoma is a relatively rare primary tumour of the kidney. We present two cases of sarcomatoid transformation in this type of renal cell carcinoma. Described transformation in chromophobe renal cell carcinoma has been reported previously only in four publications.

[Extensive metastases in the thoracic wall as an unusual manifestation of malignant hepatoma].

In a 53-year-old man an extensive tumour of the thoracic wall was extirpated. It was examined histologically and identified as a secondary of a malignant hepatoma. In the second stage a primary hepatic tumour was removed by extended right-sided lobectomy.

[Segmental mediolytic arteriopathy].

Three cases of segmental mediolytic arteriopathy occurring in abdominal muscular arteries are presented. This unusual arterial lesion is noted for cytoplasmic vacuolar degeneration of the arterial smooth muscle cells, intercellular vacuoles of various sizes, and focal arterial wall defects designated "arterial gaps". This spectrum of histologic changes can progress to formation of aneurysms with rupture of the vascular wall.
