Primary extrarenal papillary type II renal cell carcinoma presenting as a pelvic mass: a case report and review of the literature.

We report a case of a 57 years old woman with a solitary mass located in the pelvis diagnosed as an extrarenal papillary renal cell carcinoma, in the absence of a primary renal cancer. The diagnosis was based on cytomorphological features and further confirmed by immunochemistry findings following surgical excision. The hypothesis of a tumor developing in a supernumerary or ectopic kidney was excluded, since no normal renal tissue could be identified in the specimen and in the preoperative computed tomography and MRI images.

Large cystic lymphangioma of the pancreas: unusual finding with differential diagnosis and therapeutic considerations.

Lymphangiomas are rare benign tumours of lymphatic vascular origin. They are more common in the paediatric population and manifest mainly in the neck and axillary region. Retroperitoneal lymphangiomas are <1% and pancreatic origin is even rarer. We present a case of a pancreatic cystic lymphangioma in a 60-year-old woman with chronic diffuse symptoms, diagnosed because of newly onset of diabetes mellitus. She was successfully managed with distal pancreatectomy and spleenectomy en-bloc with the cystic mass without any complications. Cystic lymphangioma of the pancreas is a rare entity presenting with a challenging preoperative diagnosis as imaging modalities may provide ambiguous information. The clinician should be aware of its complicated differential diagnosis and its persistent and subtle symptomatology.

Minimally invasive treatment of pilonidal sinus using the new Infinite Ring Fiber. A case series.

AIM: In this study, we present a small series of patients with pilonidal cyst, which were treated with NeoV1470 Laser System using Infinite Ring Fiber 600 microns (Mm) (NeoLaser, Caesarea, Israel) (Infinite Ring Fiber - IRF). This fiber is characterized by circular 360-degree heat release, an active 4 mm tip with 1470nm emission and up to now it has been used only for vessel surgery. We are investigating its use in the treatment of pilonidal cyst. MATERIAL AND METHODS: It is a case series study (December 2020 - December 2021) consisting of 13 patients. The choice criterion for the study was that the patient should have at least one fistula opening with maximum size of orifice < 5mm. All patients were treated as day clinic. Surgery was performed with intravenous sedation and local anesthesia using lidocaine. The pulse regime we use was (8w, 3sec, 24 J/per pulse). RESULTS: All the patients had successful treatment. None of the patients treated with the particular fiber had any complications or relapsed disease during the follow up period. DISCUSSION: In the international literature have been described various therapeutic options of pilonidal cyst therapy. The use of use of IRF is another one. CONCLUSIONS: The use of NeoV1470 laser system with IRF at pilonidal cyst therapy appears to be a safe and effective option, with less pain and necrotic detriments.
