Extensive Presentation of Penile Carcinoma Cuniculatum a Variant of Squamous Cell Carcinoma With Low Malignant Potential.

Carcinoma cuniculatum is an uncommon variation of squamous cell carcinoma (SCC) has been documented in a few cases at various locations of the body such as penis, foot, jaw, oropharynx and esophagus. In this case, a 79-year-old male presents with a penile mass, which he underwent a total penectomy. Histology of the mass was defined as carcinoma cuniculatum with negative margins and no lymphovascular invasion. This variant of SCC rarely metastasizes. A joint decision was made to observe lymph nodes. It is important to differentiate the different SCC because patient care can be guided based on the pathology.

Malignant ascites and small renal mass: an unusual presentation of advanced renal cell carcinoma.

Metastatic renal cell carcinoma (RCC) presenting with peritoneal involvement or ascites is rare and has been previously described clinically in the setting of large renal mass or other distant metastases. We report an unusual case of RCC presenting with ascites without large mass or other distant metastases. Advances in cytologic diagnosis of metastatic RCC in serous ascitic fluid is discussed, while a potential mechanism of tumor spread is presented.

LaparoEndoscopic Single Site orchidopexy for intra-abdominal testes in the pediatric population with a multichannel single port and flexible tip laparoscope.

PURPOSE: To assess the outcomes of pediatric LaparoEndoscopic Single Site (LESS) orchidopexy using a commercially available multi-channel single port (MCSP) and flexible tip laparoscope (FTL). PATIENTS AND METHODS: A retrospective cohort study was performed of children who underwent LESS orchidopexy by a single surgeon at a pediatric institution. A commercially available MCSP was utilized at the umbilicus. A 5 mm FTL and 3 mm and 5 mm instruments were used for the dissection. Follow-up visits were performed 2-4 weeks and 6-12 months after surgery to assess position and size of the testes. RESULTS: A total of 17 patients were identified. Median age was 11 months (range 3-43). Sixteen patients underwent primary orchidopexy, including two bilateral procedures and five primary Fowler-Stephens (FS) procedures. One patient underwent a staged FS orchidopexy, with the LESS technique utilized during the second stage. Median laparoscopic dissection time for each testis was 35 minutes (range 22-40). There was no blood loss or intraoperative complications. All testes were noted to be in the scrotum without testicular atrophy. CONCLUSIONS: Our initial experience with this technique was favorable with excellent outcomes. LESS orchidopexy is facilitated with a MCSP and FTL.
