Renal resistive index correlates with peritubular capillary loss and arteriosclerosis in biopsy tissues from patients with chronic kidney disease.

Background: The renal resistive index (RI) is a Doppler-derived measure that reportedly correlates with renal histological changes and renal disease severity and outcome. The aim of this study was to investigate the factors related to the RI elevation in chronic kidney disease (CKD).

Methods: Using Doppler ultrasonography, RIs were determined in 30 patients with CKD, after which they were correlated with interstitial fibrosis, arteriosclerosis, arteriolosclerosis and peritubular capillary (PTC) density.

Cytological Features of Carcinosarcoma ex Pleomorphic Adenoma of the Parotid Gland: A Case Report.

Background: Carcinosarcoma of the salivary gland is an extremely rare tumor composed of carcinomatous and sarcomatoid components. This report describes the cytological and pathological findings of a case of carcinosarcoma ex pleomorphic adenoma arising in the right parotid gland.

Case: A 47-year-old female visited a hospital with swelling of the right parotid region, slight pain and facial palsy.

Sarcomatoid salivary duct carcinoma of the submandibular gland: a case report.

Background: Sarcomatoid salivary duct carcinoma (sarcomatoid SDC) is a rare subtype of SDC. We encountered 1 case of sarcomatoid SDC that developed from a submandibular gland pleomorphic adenoma, and we herein report our findings.

Case: A 42-year-old female had tumentia and pain in the right submental area, and therefore she underwent a close examination, wherein a right submandibular gland neoplasm was detected.

Collagenous spherulosis associated with adenomyoepithelioma of the breast: a case report.

Background: Collagenous spherulosis (CS) associated with an adenomyoepithelioma (AME) of the breast is rare. This report describes a case of CS associated with an AME of the right breast, including the cytologic and histopathologic findings.

Case: A 51-year-old female presented with a slow-growing left breast mass that had been present for 5 months.

Benign cystic teratoma of the parotid gland: a case report.

Background: Mature cystic teratomas of the major salivary glands are rare. This report describes a case of a mature cystic teratoma of the left parotid gland, including the cytologic and histopathologic findings.

Case: A 17-year-old young woman presented with a slow-growing left parotid mass that had been present for 4 years.

Cytology of pleural effusion associated with disseminated infection caused by varicella-zoster virus in an immunocompromised patient. A case report.

Background: Pleural effusion caused by varicella-zoster virus (VZV) is rare. We report a case of a woman with acute lymphocytic leukemia (ALL) who developed a pleural effusion caused by VZV infection.

Case: A 55-year-old woman with ALL treated with consolidation therapy developed skin vesicles and a pleural effusion.
