Renal mycetoma presenting with features suggesting renal malignancy: A case report.

INTRODUCTION AND IMPORTANCE: Neoplasms of the Kidney are rarely caused by actinomycetoma or other mycetoma species. Actinomycetoma is a neglected tropical disease which is not uncommon in Sudan. Usually, it is presented as skin and subcutaneous tissue lesions or mass and can affect the bone and other soft tissue. Sites of the lesion are found in lower limbs, upper limbs, head and neck and torso. CASE PRESENTATION: A 55-year-old female presented incidental left renal mass on ultrasound examination from the internal medical department. It is presented as a renal mass mimicking renal cell carcinoma with coexistence with another actinomycetoma brain mass. The histopathology report after nephrectomy confirmed the diagnosis. Patients commenced on anti-actinomycetoma treatment after nephrectomy. CLINICAL DISCUSSION: This is the first reported case in our facility which was diagnosed as a renal actinomycetoma. It was treated by surgical excision and received antibacterial treatments. CONCLUSION: This case demonstrates that renal actinomycetoma can occur in an endemic area even without cutaneous or subcutaneous lesions.

Migrating foreign body into the urinary bladder of children postperineal trauma.

Foreign body (FB) in the urinary bladder (UB) is uncommon and rarely reported in pediatric patients. FB migration into the UB is an extremely rare and unpredictable condition that needs a high index of suspicion with meticulous history taking and clinical reasoning, so diagnosis may be challenging. In this study, we report two cases of male pediatric patients from Sudan with FB in the UB, with a history of penetrating perineal trauma, both were presented with irritative lower urinary tract symptoms, history of penetrating perineal trauma, and unremarkable clinical examination. Both were diagnosed by abdominal Ultrasound study (USS) and confirmed by cystoscopy. One child was treated by endoscopic extraction, while the other was treated by open surgical extraction. The outcome of treatment of both the cases was satisfactory.

Prostate cancer clinical characteristics and outcomes in Central Sudan.

BACKGROUND: Prostate cancer is the most common cancer among Sudanese men and most patients present at a late stage. Although the incidence of prostate cancer in Sudan is low compared to other African countries, studies on prostate cancer in Sudan are limited. This study addresses the clinical characteristics and outcomes of prostate cancer in Central Sudan and its prognostic factors. METHODOLOGY: This study was conducted prospectively at the Gezira Hospital for Renal Disease and Surgery and at the National Cancer Institute at the University of Gezira, Sudan, for an 11-year period. RESULTS: During the study period, 543 patients participated in the study. Each one underwent a clinical examination, digital rectal examination and radiological staging using magnetic resonance imaging or computed tomography and provided blood samples for prostate-specific antigen (PSA) testing. The mean (SD) age of patients was 72.6 (9.9) years. At diagnosis, the majority of patients experienced lower urinary tract symptoms (LUTS; 54%), bladder outlet obstructions (OU) without (18%) or with urine retention (14%), PSA median was 100 ng/mL and the mean was 269 ng/mL, locally advanced disease (45%) or distant metastasis (46%). The age-adjusted hazard ratio (HR) of mortality was twofold, comparing patients presented with OU to patients with LUTS. Patients diagnosed with locally advanced and castration resistance prostate cancer had five times the HR compared to patients diagnosed with organ-confined prostate. On the contrary, the HR increased sevenfold for patients with distant metastasis. Gleason score did not show a significant association with survival (p = 0.249). Similarly, there was no apparent dose-response association between the PSA levels at diagnosis (p = 0.460). CONCLUSION: The findings suggest that Sudanese men who are living in Central Sudan present at diagnosis with large tumours at late stages, and high PSA levels and Gleason scores. Improving awareness and building up the treatment capacity are key to achieving better outcomes.

Renal tuberculosis mimicking renal malignancy in Sudanese adolescence.

INTRODUCTION: Renal tuberculosis (RTB) has no specific presentation and symptoms can be absent in up to 8% of cases in developing countries. Most patients present with symptoms like fever, burning micturition, pyuria, weight loss, and loin pain. In very rare occasions RTB can present as a renal mass mimicking renal cell carcinoma RCC. CASE REPORT: We report a case that was initially diagnosed as renal cell carcinoma and histopathology revealed renal tuberculosis. DISCUSSION: Tuberculosis is more common than renal cell carcinoma, the WHO states that 1 in every three individuals have TB worldwide, but something to keep in mind is that the incidence of RCC is increasing by the rate of 1% since the year 2006. Hence uncommon presentations of common diseases are more common than common presentations of uncommon diseases, then when doctors encounter a patient who is presenting with renal mass especially in countries that are endemic with TB a probability of uncommon presentation of UGTB should be considered to avoid missing the chance of treating a medically curable condition. Most of the reported cases in the literature about pseudo tumor presentation of UGTB indicate that most of the cases presented with unilateral mass mimicking RCC and TB is detected after radical nephrectomy. CONCLUSION: RTB can mimics RCC clinically and radiologically, which creates a diagnostic challenge. The chance of diagnosing renal TB in a patient presenting with renal mass is extremely lower than the chance of missing it for RCC, this because of the lack of evidence-based diagnostic approaches.
