[Abdominal stab wound involving a horseshoe kidney]. / Traumatismo abdominal por arma blanca con afectación de riñón en herradura.

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. In addition to intestinal lesions, the injury produced a lesion in a horseshoe kidney, a relatively uncommon malformation of the urinary system (1/400 individuals). Despite the rarity of this occurrence, when dealing with an emergency affecting a malformed kidney, knowledge of the inherent peculiarities of these defects is essential for the appropriate management of these patients.

Traumatismo abdominal por arma blanca con afectación de riñón en herradura / Abdominal stab wound involving a horseshoe kidney

La herida abdominal por arma blanca supone aproximadamente el 7% de los traumatismos abdominales en nuestro medio; sin embargo, la afectación renal es relativamente infrecuente en estos casos (2% de las lesiones viscerales). Se presenta un caso clínico en que una herida por arma blanca en la pared abdominal anterior produjo, además de lesiones intestinales, una lesión renal que afectaba a un riñón en herradura, malformación del sistema urinario relativamente infrecuente (1/400 individuos). A pesar de la rareza de esta eventualidad, ante una urgencia que comprometa a un riñón malformado puede ser de capital importancia conocer las peculiaridades inherentes a estas malformaciones, lo que sin duda va a permitir un correcto manejo de estos pacientes (AU)

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. We suggest that the rhabdoid phenotype could represent a type of degeneration, or a preliminary stage before apoptosis or cell necrosis, instead of a specific differentiation. In extrarenal tumors with rhabdoid features, stage and histologic types of tumors where rhabdoid changes occur are the most important prognostic factors.
