Robot-assisted partial nephrectomy in younger versus older adults with renal cell carcinoma: a propensity score-matched analysis.

Purpose: Our study aimed to compare the surgical outcomes of robot-assisted partial nephrectomy (RAPN) between younger and older patients after adjusting for their background differences. We particularly assessed RAPN outcomes and safety in older patients.

Methods: We retrospectively evaluated 559 patients clinically diagnosed with T1 renal cell carcinoma (RCC) and treated with RAPN between 2013 and 2022 at five institutions in Japan.

Fibroepithelial urethral polyp with minor prostatic glands in an older man.

We describe a man in his 60s with an incidentally detected urethral polyp located in the middle section of his penile shaft. The patient had been suffering from urinary retention for 9 years due to benign prostatic hyperplasia. He was initiated on clean intermittent catheterisation to drain urine 1 year before the detection of the urethral polyp.

Adrenal Schwannoma in an Elderly Man: A Case Report and Literature Review.

Schwannoma is a common mesenchymal neoplasm; however, adrenal schwannoma is rare, and it is frequently misdiagnosed as adrenal cortical adenoma. We herein report a 91-year-old Japanese man with right adrenal schwannoma that was pathologically diagnosed after adrenalectomy. To our knowledge, this is the first case of adrenal schwannoma in the oldest patient and with the longest follow-up period reported, including radiological images from 10 years earlier.

Penile warty mucoepidermoid carcinoma with features of stratified mucin-producing intra-epithelial lesion and invasive stratified mucin-producing carcinoma.

Aims: Stratified mucin-producing intra-epithelial lesion (SMILE) and invasive stratified mucin-producing carcinoma (ISMC) are recently described cervical and penile lesions. We report an unusual case of mixed variant of penile squamous cell carcinomas with warty, usual and mucoepidermoid SMILE/ISMC features.

Methods And Results: A 62-year-old Japanese man had a glans penis lesion of one-and-a-half years' duration, suggesting malignancy.

Acquired cystic disease-associated renal cell carcinoma: a clinicopathological study of seven cases.

The disease entity of acquired cystic disease (ACD)-associated renal cell carcinoma (RCC) has been recently incorporated into the international renal tumor classification. However, there are a few descriptions on clinicopathologic features. We performed a clinicopathologic study of seven cases with ACD-RCC.
