Prostate tuberculosis mimicking prostate cancer: Case report and literature review.

RATIONALE: Prostate tuberculosis (PTB) has no specific symptoms, or insidious presentation in male reproductive system tuberculosis, and is difficult to detect in the early stage. When PTB develops to the late stage, it leads to disease progression and irreversible organ and tissue damage. At present, the imaging manifestations of prostate tuberculosis vary and are not well known to imaging physicians and urologists. DIAGNOSES AND INTERVENTIONS: This case was a PTB patient, whose main manifestation was elevated serum prostate-specific antigen and the diagnosis was confirmed by ultrasound-guided prostate biopsy. We analyzed the imaging performance of various imaging techniques, and summarized and explored the imaging characteristics reported in the previous literature, with the aim of improving the early detection rate and providing evidence-based practice for early regular antituberculosis treatment in PTB. OUTCOMES: The multiparametric transrectal ultrasound performance of PTB is characteristic, and can be used for the differential diagnosis of prostate cancer causing elevated prostate-specific antigen levels in aged men.

[Tuberculosis of the male genital organs].

INTRODUCTION: Tuberculosis of the genitourinary system is still of importance. The observed decrease in the incidence of urogenital tuberculosis is largely due to the inaccuracies of registering this disease. MATERIALS AND METHODS: A retrospective cohort comparative non-interventional study of the structure of urogenital tuberculosis in the Siberian and Far Eastern federal districts was carried out. We analyzed statistical reports from 2003 to 2015, which included data for a total of 456 patients, as well as extended questionnaires compiled specifically for this study. In addition, outpatient records of 95 patients with urogenital tuberculosis who were registered at the Novosibirsk Regional Tuberculosis Dispensary by 01/01/2022 were evaluated. RESULTS: An analysis of the structure of urogenital tuberculosis from 2003 to 2015 showed that urinary system was affected in the most of cases (n=314, 68.8%). Tuberculosis of male and female genital organs took the second place (n=101, 22.2%) patients. Generalized urogenital tuberculosis was diagnosed in 41 (9%) patients. From 2003 to 2008, the proportion of renal tuberculosis increased by 12.6%, but then a significant decrease in its proportion was found (82.2% in 2008 vs. 48.6% in 2015 [2 =12.71; =0.0004]). On the contrary, in 2003 the proportion of genital tuberculosis was 18% (n=18) compared to 29.1% (n=3) in 2015 (2 =3.46; p=0.06). In 2015, generalized forms of urogenital tuberculosis were diagnosed in 23 (22.3%) patients, which is approximately 2.5 times more than in 2003 (n=9; 9%) and 2008 (n=7; 6.6%) (2> 6.46; p<0.01). The proportion of prostate tuberculosis ranged from 0 in 2003 and 7.1% in 2008 to 54.2% in 2013. In 2003, tuberculosis of the scrotum was diagnosed in 100% of men with genital tuberculosis, while in 2013 and 2015 its proportion was 25%. In total, scrotal tuberculosis during whole follow-up was diagnosed in 26 patients, which accounted for 41.9% of all male genital tuberculosis. The combination of tuberculosis of the scrotum and prostate also varied significantly from 17.3 to 35.7%. Generalized urogenital tuberculosis was diagnosed with a minimum proportion (1.4%) in 2008, then there was an upward trend with a maximum rate in 2015 (22.3%, 2 =29.38; <0.0001). Among 95 patients with tuberculosis of the urinary and male reproductive system, who were followed by the phthisiourologist of Novosibirsk Regional Tuberculosis Dispensary, 34 (35.8%) had a diagnosis of kidney tuberculosis, 42 (44.2%) had isolated tuberculosis of the male genital organs, and the remaining 19 (20.0%) men had generalized urogenital tuberculosis. In total, HIV infection was detected in 23 (24.2%) patients with urogenital tuberculosis, and among patients with kidney tuberculosis, it was diagnosed in 7 (20.6%) cases compared to 9 (21.4%) cases in those with male sexual tuberculosis. In patients with generalized urogenital tuberculosis, HIV infection was detected almost 2 times more often, namely in 7 (36.8%) cases. CONCLUSION: Patients with urogenital tuberculosis are under follow-up of urologists for a long time with erroneous diagnoses, and only when the disease becomes irreversible and requires surgical intervention, the pathomorphological study of the surgical material will allow to make a proper diagnosis.

Surgical management of tuberculous epididymo-orchitis: a retrospective study of 81 cases with long-term follow-up.

BACKGROUND: Nowadays, most studies of tuberculous epididymo-orchitis (TBEO) are case reports or small sample cohort series. Our study is aimed to present the largest series of TBEO with our management experiences and long-term follow-up outcomes. METHODS: Patients diagnosed with TBEO after surgical procedures at Department of Urology, West China Hospital from 2008 to 2019 were included. All clinical features, auxiliary examination results, treatment and histopathological findings were extracted if available. RESULTS: Eighty-one patients (mean age 50.77 ± 16.1 years) were included. Scrotal swelling (N = 47, 58.0%) and pain (N = 29, 35.8%) were the most common presenting complaint. Pyuria and microscopic hematuria were observed in twenty-two (27.2%) and eight patients (9.9%), respectively. Urine acid fast bacilli cultures were available in 16 patients and all were negative. The mean duration between the onset of symptoms and the definite diagnosis was 6.42 ± 7.0 months. TBEO was considered in 30 (37.0%), tumors in 28 (34.6%) and nonspecific bacterial epididymo-orchitis in 23 (28.4%) patients. All patients received triple therapy of chemotherapy-surgery-pharmacotherapy and definite diagnosis was confirmed through histopathology of surgical specimens. Fifty-five patients were followed up regularly (mean follow-up 82.35 ± 36.6 months). One patient (1.2%) died from liver cirrhosis and no recurrence was observed. Postoperative complications included erectile dysfunction in 4 patients (4.9%), premature ejaculation in 5 patients (6.2%) and sterility in 7 patients (8.6%). CONCLUSIONS: We recommend patients with advanced TBEO to receive triple therapy of chemotherapy-surgery-pharmacotherapy. Physicians should pay more attention to patients' sexual function and fertility during follow up after treatment completed.

Unusual presentations of cutaneous tuberculosis.

Cutaneous tuberculosis occurs in 1-2% of world cases of tuberculosis and more common in tropical countries. It presents with different clinical forms. Unusual clinical presentations are not uncommon and awareness of these will help in suspecting and managing these patients successfully. Lupus pernio like lupus vulgaris, tuberculosis of glans penis and lichen scrofulosorum on the distal parts of limbs are presented here because of their unusual clinical presentation.

An isolated testicular tuberculosis mimicking testicular cancer in north-central Nigeria.

Testicular tuberculosis (TB) is a rare presentation of extrapulmonary TB. A 46-year-old man presented to our Urology clinic with a painless swelling of the right testis. Examination revealed a hard, non-tender swelling on the inferior pole of the testis that measured 3 x 2 cm. Scrotal ultrasound scan showed a complex mass with multiple hypoechoic lesions at the inferior pole of the right testis with dimension 2.4 x 1.7cm. Laboratory data showed elevated alpha fetoprotein and beta hcG and lymphocytosis. A diagnosis of right testicular cancer was made and the patient had a right transinguinal radical orchidectomy. Histopathology result showed tuberculous granulomata with caseous necrosis surrounded by multinucleated giant cells (Langerhan`s type). The patient subsequently had anti-TB medications. The rarity of this condition makes these findings important to report.

Tuberculous prostatitis: a condition not confined to the immunocompromised.

SUMMARY: Tuberculous (TB) prostatitis is rare; usually occurring in immunocompromised men. It can mimic benign prostatic hyperplasia (BPH), chronic prostatitis or prostate cancer. This report in an immunocompetent 72-year-old man adds to the clinical spectrum of the five prior reported cases. A low threshold for prostatic biopsy led to a histological evaluation and subsequent microbiological confirmation of TB. This attests to the value of such an approach in arriving at the correct diagnosis and the institution of appropriate anti-tuberculous therapy even amongst immune-competent men.

Multicentre evaluation of Xpert MTB/RIF assay in detecting urinary tract tuberculosis with urine samples.

Genitourinary tuberculosis (GUTB) accounts for up to 40% of extrapulmonary tuberculosis cases. Rapid tests for GUTB are urgently needed because it is often associated with delayed health-care seeking, leading to serious consequences. This study evaluated the performance of the Xpert MTB/RIF assay in the rapid diagnosis of urinary tract tuberculosis (UTB) and rifampicin-resistant tuberculosis with urine specimens. In all, 302 patients were included from four hospitals in China. Suspected UTB patients were tested with Xpert, smear, and MGIT 960 culture. Drug susceptibility testing (DST) was conducted for culture-positive cases. The performance of the assays was evaluated against MGIT 960 culture and a composite reference standard (CRS). Among all participants, 150 (49.7%) had CRS-positive UTB, of whom 36 (24.0%) were culture-confirmed. Against culture, Xpert and smear achieved a sensitivity of 94.4% (95% CI: 81.3-99.3%) and 22.2% (95% CI: 10.1-39.2%), respectively. Against CRS, the sensitivity of Xpert, smear and culture was 41.3% (95% CI: 33.4-49.7%), 7.3% (95% CI: 3.7-12.7%), and 24.0% (95% CI: 17.4-31.6%). Xpert had better performance than smear and culture in detecting UTB from urine samples and could be considered for the diagnosis of UTB. Moreover, Xpert showed better performance than MGIT 960-based DST using urine culture.

Vas deferens sonographic appearances of tuberculosis lesions of 19 cases of male genital systemic tuberculosis.

To investigate the sonographic findings of the vas deferens in male genital tuberculosis.The ultrasonographic findings of the vas deferens of 19 cases of genital tuberculosis were retrospectively analyzed.According to the pathological and ultrasound findings, the ultrasonographic appearances of the vas deferens tuberculosis could be divided into 4 groups, 1 of normal sonograms, 3 of abnormal sonograms. The abnormal ultrasonographic appearances of the vas deferens tuberculosis were considered 3 categories as follows: diffusely thickening of vas deferens, nodular thickening of vas deferens, and space-occupying lesions adjacent to the vas deferens.The ultrasound manifestations of vas deferens in tuberculosis of the male genital system have certain characteristics. Combination of clinical manifestations, history of tuberculosis, experimental antituberculosis treatment, and ultrasound examination of vas deferens can suggest tuberculosis of vas deferens. Furthermore, it can provide objective basis for the comprehensive and noninvasive evaluation of the impact of genital tuberculosis on the reproductive ability for further treatments.

Pulmonary and testicular tuberculosis in one patient caused by Mycobacterium tuberculosis with different genotypes.

Extrapulmonary tuberculosis (EPTB) accounted for 14% of 6.4 million cases of TB that were reported to WHO in 2017, and genitourinary TB (GUTB) is the second most common type of EPTB. The most common site of GUTB is the kidneys and testicular TB is relatively rare. The case of one patient with pulmonary and testicular TB caused separately by two different genotypes of Mycobacterium tuberculosis (Mtb) is further rare. Here, we present an unusual case of TB in which pulmonary TB (PTB) and testicular TB were caused by Mtb isolates with two different genotypes in a 91-year-old male patient from Zunyi, Guizhou Province of China. A better understanding of the mechanism by which a small number of tubercle bacilli are spread from the primary site of PTB to more distant parts/organs of the body, and what factors determine the potential EPTB site will provide us with new ways to prevent and control EPTB infections.

Primary cutaneous 'ulcerative' tuberculosis of the scrotum: a rare occurrence.

Tuberculosis (TB) is a global disease and if not adequately treated can lead to morbidity and mortality. Though genitourinary TB is common and only next to pulmonary TB, cutaneous 'ulcerative' tuberculosis of the scrotum is not reported so far in the literature. We present a 32-year-old man with a non-healing scrotal ulcer and underwent excision. Histopathology was consistent with TB. Antitubercular therapy was given and at the end of a year's follow-up, there has been no recurrence. TB of the scrotum should be considered in the differential diagnosis of scrotal ulcers. Proper diagnosis and adequate treatment will offer a cure to such patients.

Two unusual reports of urogenital tuberculosis: One 'putty' kidney and another in association with benign prostatic hyperplasia.

In India urogenital tuberculosis is the second commonest form of extra-pulmonary tuberculosis. Kidney is the highest and prostate is the least affected urogenital organ. But the extreme stage of renal tuberculosis named as 'putty' kidney is a rare manifestation. In general most cases of urogenital tuberculosis are quasi-symptomatic, and therefore an uttermost apprehension is needed from physicians to intercept such cases at the earliest. In this presentation we describe a case of 'putty' kidney, and another incidental association of prostate tuberculosis with benign prostatic hyperplasia.

Scrotal skin nodule: sebaceous cyst or tuberculosis? A lesson learnt!

Tuberculosis (TB) is a great mimic of many diseases and may present a dilemma in diagnosis. Sebaceous cyst is the commonest swelling that occurs in the scrotal skin. We present a 23-year-old patient who presented with a painful hard scrotal skin nodule, clinically diagnosed to be an infected calcified sebaceous cyst, excised and reported to be due to TB. Nodular scrotal skin TB is extremely rare but should nonetheless be considered as a differential diagnosis in regions where it is prevalent. Thus, excision of any suspicious nodule is indicated.

Incidentally detected tuberculous prostatitis with microabscess

ABSTRACT Tuberculous prostatitis is a rare and often overlooked entity that may mimic prostatic adenocarcinoma on imaging exams, especially multiparametric magnetic resonance imaging (MRI) of the prostate. Detection of a prostatic abscess is a clue to the correct diagnosis.

Quantitative polymerase chain reaction analysis of serpiginous choroiditis with biopsy-proven testicular tuberculosis.

We report a case of a 47-year-old male patient presenting with diminution of vision in the left eye. The left eye fundus showed yellowish lesions with indistinct geographical margin extending over the posterior pole just abutting the macula, suggestive of diffuse choroiditis. The patient gave a history of testicular swelling for the past 2 years. Aqueous tap for polymerase chain reaction analysis was positive for IS6110 mycobacterial tuberculosis (TB) genome, and a biopsy of testicular sac was suggestive of tubercular epididymitis. A diagnosis of TB-multifocal serpiginoid choroiditis was established and was managed with anti-tubercular therapy and systemic steroids.
