We studied the pathologic features and whether clinical features could predict pathologic outcomes in small renal masses. The study included all adult patients with solitary, nonmetastatic renal masses 4 cm or smaller confirmed by nephrectomy or needle biopsy between 2004 and 2006. Tumor size, histologic type, Fuhrman nuclear grade, and stage were obtained(More)

Transmural inflammation shown by imaging and histology has been considered a hallmark of Crohn’s disease (CD).

This study aimed to evaluate the clinical utility of transmural inflammation in patients with ileal pouch–anal anastomosis (IPAA) using in vivo(More)
CONTEXT Immunohistochemical stains for androgen receptor (AR), HER-2/neu, and p53 are used as diagnostic markers associated with malignancy in several histologic types of salivary gland tumors. These markers may be useful in differentiating pleomorphic adenoma with cytologic atypia from intracapsular carcinoma ex pleomorphic adenoma (CXPA), as these tumors(More)
Carcinoma cuniculatum, a unique variant of well-differentiated squamous cell carcinoma, has been only rarely reported in the esophagus. We report 9 cases of esophageal carcinoma cuniculatum diagnosed on esophagectomy specimens in 7 men and 2 women during a 20-year period. All but 1 of the patients presented with persistent or progressive dysphagia. All(More)
