Adult cystic nephroma masquerading urothelial carcinoma of a calyceal diverticulum.

We report a complex cystic renal lesion in a 34-year-old man who presented with haematuria. It was managed by laparoscopic radical nephroureterectomy as it mimicked urothelial carcinoma.

A Study of Arginase Expression in Chronic Non-healing Wounds.

Arginase expression has been recently shown to increase in numerous disease states like neurodegeneration, inflammation, and malignancies. Although it has been found to be functionally important in various disease pathologies, little is known about its role in wound healing. Here, we look at the expression of arginase and its isoforms in chronic non-healing wounds and also study the expression of nitric oxide synthase (NOS) and oxidative stress enzymes in them.

Laparoscopic resection of a large mixed epithelial-stromal tumour of the seminal vesicle: a rare entity and review of the current literature.

Mixed epithelial-stromal tumours (MESTs) of the seminal vesicle (SV) are a rare neoplasm, with biological behaviour ranging from benign to malignant. Due to their rarity, there are no established guidelines for their treatment. We report a 37-year-old man with a large MEST of the SV which was successfully resected by laparoscopic transperitoneal approach.
