Tuberculosis of the Penis: A Review of the Literature

Tuberculous Ulcerative Skin Lesion of the Penis: A Case Report

Genitourinary tuberculosis (GUTB), especially penile tuberculosis (PTB), is a disease often overlooked by urological specialists, especially in Europe, where the pathology is less frequent. In this report, we described a case of penile tuberculosis (PTB) characterized by ulcers on the penis. After the patient was administered three months of anti-tuberculosis treatment (isoniazid 0.3 g/qd, rifampicin 0.6 g/qw, and ethambutol 0.75 g/qd), the ulcer disappeared. The patient was followed up for seven months and showed no recurrence.

Why do we miss isolated male genital tuberculosis diagnosis?

Tuberculosis remains a worldwide health problem. It can affect the entire genitourinary tract. Tuberculosis of male genital tract still presents a diagnostic dilemma because of its varied presentations and the unavailability of sensitive and specific investigations. "Urogenital tuberculosis" is the most common term used in the literature. Male genital tuberculosis (MGTB) is usually reviewed together with urinary tract tuberculosis because often both sites are involved simultaneously; however, this is not always the case and current terminology may need to be modified. Until now, little importance has been given to isolated MGTB diagnosis. The current methods used for diagnosis are not adequate and the optimal strategy warrants further studies with a special attention on the evaluation of sperm investigations. In this review, we aim to establish a summary on the type of tuberculosis affecting only the male genital tract. We recommend that the diagnosis of MGTB should be made taking into consideration the epidemiological data, the clinical presentation, and performance of latest molecular or immunological tools from urine, sperm, blood, other fluids or tissue specimens.

Genitourinary Tuberculosis: A Comprehensive Review of a Neglected Manifestation in Low-Endemic Countries

Genitourinary tuberculosis (GUTB) represents a disease often underestimated by urological specialists, particularly in settings such as the European one, where the pathology is less frequent. Similar to other uncommon diseases at these latitudes, GUTB is a neglected clinical problem. In this light, the aim of this review is to give a comprehensive overview of GUTB in order to provide a useful tool for urologists who seldomly manage this disease. A non-systematic review of genitourinary tuberculosis was performed on relevant articles published from January 1990 to July 2021 using PubMed, Scopus, and the Cochrane Central Register of Controlled Trials. GUTB represents up to a quarter of extrapulmonary tuberculosis (EPTB) cases. Diagnostic, therapeutic and surgical work-up have been deeply reviewed and summarized. The mass migration of refugees to Europe as well as the ease of international travel is gradually leading to an upsurge in urological diseases such as GUTB, which were previously only rarely encountered in some European countries. The poor TB knowledge of European urologists should be improved through medical education courses, webinars or telematic means.

Primary tuberculosis of the glans penis: A rare presentation and review of literature

Tuberculosis poses a real public health problem inTunisia.We report an 80-year old patient, immunocompetent, who has initial presentation of a painless ulcerative lesions of the glans penis. A history of pulmonary tuberculosis was not present.The physical examination revealed an indurated glans penis covered with blackish crusts and small ulcerations. A biopsy of the lesion was undertaken and histological examination was confirmed the diagnosis of tuberculosis of glans.Others investigations was performed without finding any abnormalities He responded well to anti-tubercular treatment with complete resolution of lesions in six months.

Necrotising granulomatous mass of the foreskin with inguinal lymphadenopathy: a rare presentation of syphilis

We report the case of a 24-year-old man who presented with a 5-week history of painful right inguinal lymphadenopathy, weight loss and non-ulcerative foreskin mass. The patient’s symptoms progressed despite initial antibiotic therapy. The foreskin mass was clinically suspicious for squamous cell carcinoma; however, histopathology of both the foreskin mass and inguinal lymph node showed necrotising granulomatous inflammation. Extensive immunohistochemistry testing was inconclusive and could not identify a causative microorganism. Ultimately, serology was positive for Treponema pallidum and he was treated with intramuscular benzathine penicillin. This is an unusual case, which highlights the importance of extensive investigation for differential diagnoses of penile mass and exemplifies the resurgence of syphilis in developed countries.

Urological infections in the developing world: an increasing problem in developed countries

PURPOSE

Infectious diseases that often follow geographical distribution patterns are increasingly crossing such boundaries, aided by human travel and commerce. These pose a new challenge to physicians who are required to diagnose previously unseen conditions and address drug-resistant organisms. We review some such common infections.

METHODS

A literature review was performed for six common urological infections and a narrative review based on recent publications on these infections was compiled.

RESULTS

In Urology, some infections that are now crossing geographical boundaries include Brucellosis, Schistosomiasis, Tuberculosis, Filariasis, Hydatidosis and emphysematous pyelonephritis. Brucellosis, a zoonotic infection, is common in the Mediterranean areas, Asia, South America and Africa. Infection can involve all parts of the genitourinary tract. Schistosomiasis, a parasitic disease, is particularly common in Sub-Saharan Africa and may have bacterial superinfection. Voiding symptoms are common and bladder carcinoma may develop. Tuberculosis affects almost every organ in the body and in the male genital system, often presents with abscesses, nodules, ulcers and infertility that is difficult to manage. Filariasis is caused by two species of worms and is transmitted through a bite from a mosquito carrying larvae of the worm. It causes lymphatic obstruction leading to scrotal edema, hydrocoele to elephantiasis of scrotum. Emphysematous pyelonephritis is a life-threatening suppurative necrotizing infection of the renal parenchyma. While not being geographically limited, it is more common in developing areas with poor health care access. Genitourinary hydatidosis is a rare disease that is associated mainly with renal involvement in the genitourinary tract. Large cysts with destruction of renal parenchyma may be found.

CONCLUSIONS

Although uncommon, these urological infections are associated with significant morbidity and mortality and awareness in all healthcare settings is now an essential requirement.

Extensive Primary Male Genital Tuberculosis

Genital tuberculosis (GTB) is uncommon, and the most common genital sites of tuberculous infection are epididymis and prostate; isolated testicular TB is extremely rare, comprising only 3% of GTB. The usual modes of genital involvement include descending infection from the kidneys, intracanalicular or direct extension from neighboring foci in the genital tract, and hematogenous dissemination. Ultrasonography (USG) and USG-guided fine-needle aspiration cytology of testicular swelling may confirm the diagnosis of GTB. Anti-TB chemotherapy is the mainstay of treatment to ensure the complete resolution of the lesion. Infertility in GTB is a result of obstruction at the terminal portion of the ejaculatory duct, resulting in dilatation of the proximal ductal system including the vas deferens preventing seminal vesicle secretions from reaching the ejaculate. Seminal vesicle secretions make up the bulk of the ejaculate, contain fructose, and alkalinize the ejaculate, and with obstruction, patients present with azoospermia or aspermia. Here, we present a rare case of extensive primary GTB in a 36-year-old male.

Urogenital tuberculosis - epidemiology, pathogenesis and clinical features

Tuberculosis (TB) is the most common cause of death from infectious disease worldwide. A substantial proportion of patients presenting with extrapulmonary TB have urogenital TB (UG-TB), which can easily be overlooked owing to non-specific symptoms, chronic and cryptic protean clinical manifestations, and lack of clinician awareness of the possibility of TB. Delay in diagnosis results in disease progression, irreversible tissue and organ damage and chronic renal failure. UG-TB can manifest with acute or chronic inflammation of the urinary or genital tract, abdominal pain, abdominal mass, obstructive uropathy, infertility, menstrual irregularities and abnormal renal function tests. Advanced UG-TB can cause renal scarring, distortion of renal calyces and pelvic, ureteric strictures, stenosis, urinary outflow tract obstruction, hydroureter, hydronephrosis, renal failure and reduced bladder capacity. The specific diagnosis of UG-TB is achieved by culturing Mycobacterium tuberculosis from an appropriate clinical sample or by DNA identification. Imaging can aid in localizing site, extent and effect of the disease, obtaining tissue samples for diagnosis, planning medical or surgical management, and monitoring response to treatment. Drug-sensitive TB requires 6-9 months of WHO-recommended standard treatment regimens. Drug-resistant TB requires 12-24 months of therapy with toxic drugs with close monitoring. Surgical intervention as an adjunct to medical drug treatment is required in certain circumstances. Current challenges in UG-TB management include making an early diagnosis, raising clinical awareness, developing rapid and sensitive TB diagnostics tests, and improving treatment outcomes.

[Dermato-urology: Male genital lesions urologist should know]

This article aimed to gather male genital dermatoses that may lead to consult a urologist, except pre-neoplastic or neoplastic lesion.

METHOD

This review is based on a research on Pubmed and EM-consult database, in English and in French, using the following key terms "male genital dermatoses", "male genital lesions", "balanitis", "balanoposthitis", "dermatoses des organes génitaux externes masculines", "lésions des organes génitaux externes de l'homme", "balanoposthites".

RESULTS

It highlights normal morphological aspects, acute balanoposthitis (nonspecific, infectious, allergic, irritative and traumatic), common skin disease localized to male genital and male genital specific dermatoses.

CONCLUSION

Any suspicious, fixed, must lead to a skin biopsy.

Tuberculosis of the glans penis: an important differential diagnosis of genital ulcer disease

We report a 45-year-old, apparently healthy sero-negative man, presenting with multiple ulcers on the glans penis for a duration of three months. There was no significant inguinal lymphadenopathy. He showed no improvement on systemic antibiotics and acyclovir. Histopathology revealed the diagnosis of genital tuberculosis (TB), and polymerase chain reaction for Mycobacterium tuberculosis tested positive. The patient responded well to category I anti-tubercular treatment with complete resolution of lesions in six months. It is important to consider a differential diagnosis of penile TB in patients with non-healing genital ulcers.

Genital tuberculosis: current status of diagnosis and management

Genitourinary Tuberculosis (GUTB) is the second most common extra-pulmonary manifestation of tuberculosis (Tb) and an isolated involvement of genital organs is reported in 5–30% of the cases. Genital involvement results from primary reactivation of latent bacilli either in the epididymis or the prostate or by secondary spread from the already infected urinary organs. The epididymis are the commonest involved organs affected primarily by a hematogenous mode of spread. Tb is characterized by extensive destruction and fibrosis, thus an early diagnosis may prevent function and organ loss. The gold standard for diagnosis is the isolation and culture of mycobacterium tuberculosis bacilli and in the cases of suspected GUTB, it is commonly looked for in the urinary samples. All body fluid specimens from possible sites of infection and aspirates from nodules must also be subjected to examination. Radiologic investigations including ultrasonography and contrast imaging may provide supportive evidence. Anti-tubercular chemotherapy is the first line of management for all forms of genital Tb and a 6 months course is the standard of care. Most patients with tubercular epididymo-orchitis respond to antitubercular therapy but may require open or percutaneous drainage. Infertility resulting from the tubercular affliction of the genitalia is multifactorial in origin and may persist even after successful chemotherapy. Multiple organ involvement with obstruction at several sites is characteristic and most of these cases are not amenable to surgical reconstruction. Thus, assisted reproduction is usually required. Post treatment, regular annual follow up is recommended even though, with the current multi drug therapy, the chances of relapse are low.

Case series of genital tuberculosis

Genital tuberculosis (TB) is a rare, comprising <0.5% cases of extrapulmonary TB. Among cases of genitourinary TB, glandular TB is even rarer. Its a diagnosis of exclusion. Most patients present later in the course of disease due to the associated stigma in view of site of involvement and the hesitancy on the patients's part. We saw two such cases of nonhealing genital ulcers in immunocompetent males.

Necrotizing granulomatous inflammation of the glans penis

We describe the case of a 73-year-old man who presented with a 10-month history of an ulcerating lesion on the glans penis. Initially this was thought to be an invasive squamous cell carcinoma but a biopsy showed histological features consistent with necrotizing granulomatous inflammation. Extensive serological, immunological and microbiological tests only showed a positive antinuclear and perinuclear antineutrophil cytoplasmic antibodies indicating a possible autoimmune aetiology but an underlying systemic cause was not identified. Treatment with oral corticosteroids limited the inflammatory process but due to the gross destruction of the glans penis, he still required a glansectomy and split-skin graft reconstruction from which he recovered well. Although this patient ultimately required surgery for this rare presentation, this case highlights the differential diagnosis of penile ulceration (that transcends neoplasia) and the importance of performing and interpreting penile biopsies before undertaking potentially mutilating definitive surgery.
