Giant condyloma acuminatum of the scrotum in a man with AIDS: a case report

Abstract Introduction Giant condyloma acuminatum, also called a Buschke-Löwenstein tumor, first described in 1925, is a slow-growing, locally aggressive, destructive tumor of the ano-genital region. Scrotal tumors are rare. Reports on giant condyloma acuminatum lesions in patients with HIV and AIDS are surprisingly even rarer. Case presentation In this report, we present the case of a 42-year-old African man with AIDS who was undergoing anti-retroviral therapy. He was found to have a giant condyloma acuminatum of the scrotum. Wide surgical excision and scrotal reconstruction with a pedicled anterolateral thigh flap was performed, significantly improving his quality of life. Conclusion Decision making regarding the goals of surgical intervention in the terminally ill is a complex process. The options include conservative medical palliation or palliative excision versus a curative excision that has the potential for significant morbidity. Wide surgical excision with local flap reconstruction significantly improved the quality of life of the patient described herein. The challenges presented by emerging or unusual presentations of surgical pathology secondary to HIV and AIDS in patients who are on anti-retroviral therapy provide an opportunity for research and the establishment of guidelines for the use of adjuvant chemotherapy in these patients.</p

T-staging of rectal cancer: accuracy of 3.0 Tesla MRI compared with 1.5 Tesla

OBJECTIVES: Magnetic resonance imaging (MRI) is not accurate in discriminating T1-2 from borderline T3 rectal tumors. Higher resolution on 3 Tesla-(3T)-MRI could improve diagnostic performance for T-staging. The aim of this study was to determine whether 3T-MRI compared with 1.5 Tesla-(1.5T)-MRI improves the accuracy for the discrimination between T1-2 and borderline T3 rectal tumors and to evaluate reproducibility. METHODS: 13 patients with non-locally advanced rectal cancer underwent imaging with both 1.5T and 3T-MRI. Three readers with different expertise evaluated the images and predicted T-stage with a confidence level score. Receiver operator characteristics curves with areas under the curve (AUC) and diagnostic parameters were calculated. Inter- and intra-observer agreements were calculated with quadratic kappa-weighting. Histology was the reference standard. RESULTS: Seven patients had pT1-2 tumors and six had pT3 tumors. AUCs ranged from 0.66 to 0.87 at 1.5T vs. 0.52-0.82 at 3T. Mean overstaging rate was 43% at 1.5T and 57% at 3T (P = 0.23). Inter-observer agreement was kappa 0.50-0.71 at 1.5T vs. 0.15-0.68 at 3T. Intra-observer agreement was kappa 0.71 at 1.5T and 0.76 at 3T. CONCLUSIONS: This is the first study to compare 3T with 1.5T MRI for T-staging of rectal cancer within the same patients. Our results showed no difference between 3T and 1.5T-MRI for the distinction between T1-2 and borderline T3 tumors, regardless of expertise. The higher resolution at 3T-MRI did not aid in the distinction between desmoplasia in T1-2-tumors and tumor stranding in T3-tumors. Larger studies are needed to acknowledge these findings
