ULTRASOUND GUIDED PERCUTANEOUS SCLEROTHERAPY OF SIMPLE RENAL CYSTS: PRIMARY SUCCESS AND PROCEDURE SAFETY

Svrha: Procijeniti primarni (tehnički) uspjeh i sigurnost procedure perkutane skleroterapije jednostavnih cista bubrega vođene ultrazvučno 96%-tnim etanolom. Bolesnici: 17 bolesnika sa simptomatskim jednostavnim cistama bubrega upućenih od nefrologa ili urologa. Metode: Perkutana punkcija ciste vođena UZ-om s 18 G (gauge) iglom i »pigtail« kateterom debljine 5 F (French), drenaža i inspekcija sadržaja ciste te instilacija etanola. Rezultati: Kod 2 upućena bolesnika punkcija nije učinjena zbog ciste Bosniak II i blizine hilusa bubrega. U 15 bolesnika učinjene su punkcija i drenaža sadržaja ciste. U 4 bolesnika etanol nije instiliran zbog gustog ili krvavog sadržaja ciste, blizine hilusa bubrega i jake boli pri pokušaju instilacije etanola. U 11 bolesnika uspješno je učinjena sklerozacija ciste. Prosječna veličina sklerozirane ciste bila je 8 cm (raspon 6 – 12 cm). Nije bilo znatnijih komplikacija. Zaključak: Perkutana sklerozacija jednostavnih cista bubrega vođena UZ-om lako je izvediva i za bolesnika sigurna metoda, uz prethodnu dobru selekciju cista pogodnih za sklerozaciju.Objective: To evaluate primary (technical) success and procedure safety in ultrasound (US)-guided percu­taneous sclerotherapy of simple renal cysts, using 96% ethanol. Patients: 17 patients with symptomatic simple renal cysts referred by nephrologists or urologists. Methods: US-guided percutaneous puncture of the cyst with an 18G (gauge) needle and a »pigtail« 5F (French) catheter, drainage and inspection of the cyst content, and injection of ethanol. Results: Puncture was rejected in two referred patients because of Bosniak II cyst and renal hilum proximity. 15 patients underwent puncture and drainage of the cyst content. In 4 patients ethanol was not injected because: thick or bloody cyst, proximity of renal hilum and severe pain during injection of ethanol. 11 patients underwent sclerotherapy of the cyst. The average size of sclerosed cyst was 8 cm (range 6–12 cm). There were no significant complications. Conclusion: US-guided percutaneous sclerotherapy of simple renal cysts is easy to perform and safe procedure, with the previous good selection of cysts that are suitable for the sclerotherapy

Myeloid Sarcoma Involving the Breast

Myeloid sarcoma is a tumor mass with extramedullary growth pattern, composed of myeloblasts or immature myeloid cells. The development of myeloid sarcoma may precede or concur with acute or chronic myeloid leukemia (AML or CML) or other myeloproliferative diseases or myelodysplastic syndromes (MDS). Isolated myeloid sarcoma of the breast is very rare. A case is presented of a 25-year-old, previously healthy woman that presented to our department for a palpable node, 5x2 cm in size, in the upper medial quadrant of her left breast. Fine needle aspiration (FNA) produced a sample consisting of medium sized blasts. Additional work-up revealed anemia, thrombocytopenia and leukocytosis, along with atypical blasts detected in peripheral blood and bone marrow smear. Based on the morphology, cytochemical characteristics and immature cell immunophenotype, it was considered a case of acute myeloid leukemia without maturation. In spite of intensive chemotherapy, the patient died within a year of diagnosis. In cases of isolated breast myeloid sarcoma, the diagnosis can be missed if the possibility of myeloid sarcoma is not remembered on differential diagnosis of a breast neoplasm

Hydronephrotic Kidney Previously Treated for Tuberculosis: Rare Primary Squamous Cell Carcinoma of Renal Pelvis Diagnosed by Fine-needle Aspiration Cytology

Primary squamous cell carcinoma (SCC) of the renal pelvis is a very rare tumor often associated with renal calculi and chronic infections. There are only a few articles in literature which report renal pelvis SCC in kidneys treated for renal tuberculosis, diagnosed after nephrectomy. We report the case of SCC in a hydronephrotic kidney previously treated for tuberculosis, diagnosed by ultrasound (US)-guided fine-needle aspiration cytology (FNAC), prior to core biopsy and nephrectomy. Our report highlights the utility of FNAC and the need for a careful search for renal collecting system tumors, in patients previously treated for renal tuberculosis
