Interobserver variations in reporting of prostatic adenocarcinoma using core biopsy specimens: a retrospective study from a tertiary referral hospital in Saudi Arabia

In recent years, greater numbers of prostate biopsy cores are being submitted for histopathological assessment, with a concomitant increase in workload for the pathologist. This retrospective study aimed to assess the concordance and interobserver variation between histopathologists in reporting prostatic adenocarcinoma using material obtained from prostatic core biopsy specimens. A total of 810 prostatic needle core biopsy specimens obtained from 100 patients with suspected prostatic adenocarcinoma were retrieved from the archival material at King Khalid University Hospital, Riyadh, and classified independently by 3 experienced histopathologists who were blinded to the original diagnosis. There was considerable interobserver agreement between the pathologists, with unweighted kappa scores ranging from 0.69-0.85. We would encourage other hospital pathologists to review periodically the uniformity of diagnoses in an attempt to improve their practices in prostate gland pathology

Solitary arteriovenous hemangioma of the lung without fistula: report of a case and literature review

Arterio-venous hemangiomas [also called vascular malformations] are uncommon lesions in general and very rarely reported as solitary lung tumors with no evidence of fistula formation or clinical evidence of shunting. We report the case of a 49 year old Indian male who presented to our institution with a right hilar lung mass which was histologically proven to be a classical arterio-venous hemangioma [vascular malformation]. The patient did not have clinical or radiological evidence of fistula or shunts formation
