[Study of the physical-chemical factors in patients with renal lithiasis].

Objectives: Urinary lithiasis has a multifactorial origin with participation of physical, chemical and anatomical factors. Physical-chemical factors of renal-prerenal origin are the consequence of exogenous or endogenous agents, which are integrated under the name of systemic diseases associated with urinary lithiasis. The objective of the urinary metabolic study is to know and to analyze the physical-chemical factors by which each of these diseases or clinical entities participate in the lithogenesis.

[Abdominal stab wound involving a horseshoe kidney].

Abdominal stab wounds represent approximately 7% of abdominal injuries in our environment. However, renal involvement in these cases is relatively uncommon (2% of visceral lesions). We present a case of a stab wound in the anterior abdominal wall.

[Squamous carcinoma of the penis with a rhabdoid phenotype].

Objective: To describe a squamous cell carcinoma of the penis with rhabdoid phenotype. We believe that only three squamous cell carcinomas with rhabdoid cells have been previously published and none of them was located in the penis.

Methods And Results: A 76 year old man presented a tumoral lesión in his penis, which had all the light microscopic and immunohistochemical features of a squamous cell carcinoma with rhabdoid phenotype.

Squamous cell carcinoma of the penis with rhabdoid features.

A 76-year-old man presented with a tumoral lesion in his penis that had all the light microscopic and immunohistochemical features of a squamous cell carcinoma with rhabdoid phenotype. We believe that this is the fourth reported case of squamous cell carcinoma with rhabdoid features and the first one located in the penis. Rhabdoid cells were primarily located in areas with an alveolar pattern, most of them being isolated and intermixed with necrotic cells and necrotic debris.
