    Management of extramammary Paget’s disease with a staged, modified Mohs technique

    Anant Shukla1, Matthew Stringer2, Pansy Uberoi2, Steven Hudak2, George Kallingal2

    Canadian Journal of Urology, Vol.23, No.4, pp. 8382-8384, 2016

    Abstract Extramammary Paget’s disease (EMPD) is a rare intraepithelial adenocarcinoma arising from apocrine glands. We describe an innovative surgical technique to manage extensive cutaneous malignancies in a notoriously challenging location. The patient is a 78-year-old male who presented with “jock itch” on his left groin refractory to topical treatment. A shave biopsy of the lesion demonstrated non-invasive EMPD which yielded a urology consult. Rather than the standard wide local excision (WLE), which can lead to positive margins, progression, and recurrence, we used a modified the Mohs technique and staged the procedure, providing excellent oncologic and cosmetic More >

    Magnetic resonance imaging for intratesticular and extratesticular scrotal lesions

    Jeffrey M. Woldrich, Ronald D. Im, Fiona M. Hughes-Cassidy, Lejla Aganovic, Kyoko Sakamoto

    Canadian Journal of Urology, Vol.20, No.4, pp. 6855-6859, 2013

    Abstract Introduction: To evaluate magnetic resonance imaging (MRI) utility in intratesticular and extratesticular scrotal diseases.
    Materials and methods: Two radiologists retrospectively reviewed images of patients who underwent ultrasound followed by MRI, categorizing them as intratesticular or extratesticular and malignant, benign, indeterminate, or inadequate study. For patients who underwent surgical excision, pathologic results were also correlated to the presurgical ultrasound and MRI diagnoses.
    Results: Of 69 cases, 38 were intratesticular lesions and 31 were extratesticular lesions. MRI and ultrasound diagnoses were discordant in 21 (55.32%) intratesticular and 19 (61.3%) extratesticular lesions. MRI diagnosis was malignant after an indeterminate ultrasound in… More >

    CASE REPORT

    Intravesical condylomata accuminata in HIV positive patient

    John Lazarus, Lisa Kaestner

    Canadian Journal of Urology, Vol.18, No.2, pp. 5663-5665, 2011

    Abstract A 48-year-old HIV positive woman presented with urgency, frequency, recurrent cystitis and episodic macroscopic hematuria. Cystoscopy revealed papillary lesions involving most of the bladder. Histology of bladder biopsies revealed human papilloma virus (HPV) associated condyloma acuminata. We discuss the treatment of this rare lesion and review the literature. More >

    A rare presentation of nephrogenic adenoma: multiple upper tract lesions in a female patient

    Dock Winston1, Jennifer K. Yates2, Ravi Munver1,2, Debra Fromer1,2

    Canadian Journal of Urology, Vol.18, No.6, pp. 6064-6065, 2011

    Abstract Nephrogenic adenomas are rare benign lesions of the urinary tract occurring most frequently in the bladder of male patients. We report the case of a female patient presenting with gross hematuria, which lateralized to the left ureter on cystoscopy. At the time of ureteroscopy, two polypoid lesions were identified in an upper and lower pole calyx, which were found on biopsy to be nephrogenic adenomas. In addition to reporting this case, we review the literature for the pathophysiology of nephrogenic adenomas. More >

    Semi-automatic Segmentation of Multiple Sclerosis Lesion Based Active Contours Model and Variational Dirichlet Process

    Foued Derraz1, Laurent Peyrodie2, Antonio PINTI3, Abdelmalik Taleb-Ahmed3, Azzeddine Chikh4, Patrick Hautecoeur5

    CMES-Computer Modeling in Engineering & Sciences, Vol.67, No.2, pp. 95-118, 2010, DOI:10.3970/cmes.2010.067.095

    Abstract We propose a new semi-automatic segmentation based Active Contour Model and statistic prior knowledge of Multiple Sclerosis (MS) Lesions in Regions Of Interest (RIO) within brain Magnetic Resonance Images(MRI). Reliable segmentation of MS lesion is important for at least three types of practical applications: pharmaceutical trails, making decision for drug treatment, patient follow-up. Manual segmentation of the MS lesions in brain MRI by well qualified experts is usually preferred. However, manual segmentation is hard to reproduce and can be highly cost and time consuming in the presence of large volume of MRI data. In other… More >

    Urethral carcinosarcoma from bladder carcinosarcomatous lesions: analysis of clinicopathological features

    Trinity J. Bivalacqua1, Herman S. Bagga1, Kaustubha Patil1, Ahmed Magheli1, Janis M. Taube2, Thomas J. Guzzo1, Mark L. Gonzalgo1

    Canadian Journal of Urology, Vol.16, No.1, pp. 4512-4515, 2009

    Abstract Carcinosarcoma (CS) of the bladder is a rare malignancy of the genitourinary tract that is highly aggressive with unfavorable prognoses. Data regarding the epidemiological and clinicopathological characteristics of CS of the urinary bladder have been limited due to the low reported incidence of the tumor. In particular, there is little evidence on recurrence patterns and surveillance after definitive surgical therapy. In this case report, we describe a urethral recurrence of CS after radical cystoprostatectomy for CS of the bladder. The goal of this case report is to review our current understanding of the pathological and More >

    Cutaneous BCG of the penis after intravesical therapy for bladder cancer: a case report in a 66-year-old male

    Shahab Hillyer , Frederick A. Gulmi

    Canadian Journal of Urology, Vol.16, No.5, pp. 4866-4869, 2009

    Abstract Objective: Transitional cell carcinoma of the bladder is commonly treated with intravesical BCG. We report a cutaneous complication of BCG after therapy in 66-year-old male 4 years after initiating treatment.
    Materials and methods: A case review including pathological slides, laboratory data, and radiographic findings.
    Results: Biopsy findings showed an ill defined granulomatous process with chronic inflammation and necrosis.
    Conclusion: The patient was managed on antituberculous therapy for a period of 6 months with resolution of symptoms. More >

    Rectal gastrointestinal stromal tumor mimicking a primary prostatic lesion

    Brendan C. Dickson1, John R. Srigley2, Aaron F. Pollett3, Martin E. Blackstein4, John D. Honey5, Jonathan W. Juco6

    Canadian Journal of Urology, Vol.15, No.3, pp. 4112-4114, 2008

    Abstract The interstitial cells of Cajal have been identifi ed in locations beyond the gastrointestinal tract, including the prostate, uterus and bladder. Indeed, there are reports of primary gastrointestinal stromal tumor (GIST) arising from each of these sites. We report the case of a 72-year-old male who presented with benign prostatic hypertrophy and was diagnosed on retropubic prostatectomy as having a GIST. While the initial clinical and radiologic impression was that of a primary prostatic GIST, subsequent imaging ultimately revealed a small rectal extension as the source of the lesion. The purpose of our report is More >

    Non-palpable testicular lesion: the case for testicular preservation

    George J. Assaf

    Canadian Journal of Urology, Vol.13, No.2, pp. 3034-3038, 2006

    Abstract Objectives: To report our experience in the management of patients with non-palpable lesions of the testis with a review of published studies. Even though radical orchiectomy remains the golden standard treatment for solid testicular masses there is an increasing role for testes-sparing surgery in a select group of patients with non-palpable tumors.
    Patients and methods: Between April 2000 and October 2004, a non-palpable testicular lesion was discovered on ultrasonography in six patients. Ultrasonography was performed for infertility in two patients, for testicular pain in three patients, and in one case for previous history of seminoma in the More >
