BACKGROUND: Nocardia is an ubiquitous soil organism. As an opportunistic pathogen, inhalation and skin inoculation are the most common routes of infection. Lungs and skin are the most frequent sites of nocardiosis. Testis is a highly unusual location for nocardiosis.
METHODS: We report the case of an immunocompromised 75-year-old-man admitted for fever of unknown origin. He presented with skin lesions after gardening and was first suspected of Mediterranean spotted fever, but he did not respond to doxycycline. Then, physical examination revealed new left scrotal swelling that was compatible with a diagnosis of epididymo-orchitis. The patient\'s condition did not improve despite empirical antibiotic treatment with the onset of necrotic scrotal abscesses requiring surgery. Nocardia brasiliensis yielded from the removed testis culture. High-dose trimethoprim-sulfamethoxazole and ceftriaxone were started. Multiple micro-abscesses were found in the brain and spinal cord on imaging studies. After 6 weeks of dual antibiotic therapy for disseminated nocardiosis, slight regression of the brain abscesses was observed. The patient was discharged after a 6-month course of antibiotics and remained relapse-free at that time of writing these lines. Trimethoprim-sulfamethoxazole alone is meant to be pursued for 6 months thereafter. We undertook a literature review on previously reported cases of genitourinary and urological nocardiosis; to date, only 36 cases have been published with predominately involvement of kidney, prostate and testis.
CONCLUSIONS: To the best of our knowledge, this is the first case of Nocardia brasiliensis simultaneously infecting skin, testis, brain and spinal cord in an immunocompromised patient. Knowledge on uncommon forms of nocardiosis remains scarce. This case report highlights the difficulty of diagnosing atypical nocardiosis and the importance of prompt bacteriological sampling in case of empirical antibiotics failure.

Blastomyces dermatitidis is an environmental fungus endemic to parts of Eastern North America that notably causes pulmonary infection in humans and other animals with the potential for extrapulmonary spread, particularly in immunocompromised hosts. However, it rarely presents with genitourinary (GU) tract involvement. Herein, we present a unique case of a 37-year-old immunocompetent male with genitourinary blastomycosis with the initial presentation of a scrotal abscess.

BACKGROUND: The incidence of mucinous appendiceal adenocarcinomas (MAA) has increased over the past three decades. Advanced stage tumor diagnosis is likely attributable to non-specific findings. Here we describe advanced stage appendiceal MAA presenting as inguinal ulcers, scrotal abscesses, and other nonspecific symptoms. To our knowledge, this is the first report of MAA presenting as inguinal pain with inflamed phlegmonous tissue and scrotal abscess.
METHODS: A 67-year-old male presented to a rural facility complaining of weight-loss, fatigue, hematuria, dysuria, painful right inguinal ulceration, and right scrotal abscess drainage. Computed tomography of the abdomen and pelvis revealed a distended appendix (> 1.3 cm) and a fistula between the appendix, urinary bladder, right scrotum, and right groin. Laparoscopic appendectomy was performed and diagnosed as MAA. After a right hemicolectomy, the MAA was staged as pT3b pN0 M0 G2.
CONCLUSIONS: This case highlights a unique presentation of late stage appendiceal MAA. Due to the increased incidence of appendiceal MAAs, reports of unique clinical features are needed to facilitate early diagnosis and intervention, especially in rural settings with limited access to specialists.

Penile cancer is a very rare malignancy and it is usually identified as a nodule or an ulceration. We report a case of locally advanced penile cancer presented as a urethral stricture and recurrent scrotal abscess. The patient had been treating for obstructive voiding symptoms and septic condition for 5 months. Because of persistent symptoms, a drainage of the abscess was performed and the histopathological examination showed infiltrating moderately differentiated squamous cell carcinoma of penis. He underwent a surgical Emasculation followed by the administration of a combination of chemotherapy (paclitaxel, ifosfamide, and cisplatin). We highlight the importance of including penile cancer in the differential diagnosis of scrotal abscess and urethral stricture. A multimodal approach is an effective strategy to manage the disease.

Bulbourethral syringocele is an uncommon and under-diagnosed condition most commonly seen in the paediatric population, although there is increasing recognition in adults. Due to the difficulty in diagnosis, we report our experience of urethral syringocele in a quaternary paediatric hospital, with differing presentations, diagnosis and treatment.
This is a retrospective review of seven cases of children over a period of 14 years, including their presentations, diagnosis, treatment and follow-up. A review of the current literature is presented.
The median age of these seven cases at presentation was 11 years (6 days to 16 years). Clinical features varied with age, with obstructive uropathy in a neonate, urinary tract infection in an infant, scrotal abscess in two children and lower urinary tract obstructive symptoms in three teenagers. Diagnostic voiding cystogram diagnosed the majority of syringoceles and two were seen on magnetic resonance imaging. Five boys underwent endoscopic transurethral deroofing and two children required transperineal marsupialization. Long-term follow-up showed all had complete resolution of symptoms.
Urethral syringocele presents from the neonatal period to late adolescence, with the presenting features reflective of age. Surgical management can be performed endoscopically or by open approach. Awareness of this condition and inclusion in the differential diagnosis, particularly in the setting of an atypical or recurrent scrotal abscess, could avoid a prolonged therapeutic course.

Syphilis is notorious and a great imitator of all diseases. It is a chronic bacterial infection, caused by the sexually transmitted spirochete, Treponema pallidum. Though it has drastically reduced in prevalence, its recent resurgence (especially with HIV disease) is worrying. Without treatment, the disease can progress over years through a series of clinical stages and lead to irreversible neurological or cardiovascular complications. The disease may occur in any organ, including the testis, and is commonly mistaken for malignancy. We report a case of scrotal abscess consequent on epididymo-orchitis, confirmed by histopathological examination to be syphilitic in origin, in an immunocompromised HIV-positive patient.

OBJECTIVE: To report a series of scrotal abscess, a rare problem, their etiology, and management.
METHODS: A retrospective study of children who presented with scrotal abscess between January 2010 and March 2015, analyzed with respect to clinical features, pathophysiology of spread and management.
RESULTS: Eight infants and a 3-year-old phenotypically male child presented with scrotal abscess as a result of abdominal pathologies which included mixed gonadal dysgenesis (MGD) [1]; three anorectal malformations with ectopic ureter [1], urethral stricture [1], and neurogenic bladder [1]; meconium peritonitis with meconium periorchitis [2], ileal atresia [1], and intra-abdominal abscess [1]; posturethroplasty for Y urethral duplication with metal stenosis [1] and idiopathic pyocele [1]. Transmission of the organism had varied routes include fallopian tube [1], urethra ejaculatory reflux [4], hematogenous [2], and the patent process of vaginalis [2]. Two of the nine required extensive evaluation for further management. Treating the predisposing pathology resolved scrotal abscesses in eight of nine patients, one of whom, required vasectomy additionally. Idiopathic pyocele responded to needle aspiration and antibiotics.
CONCLUSIONS: Scrotal abscess needs a high index of suspicion for predisposing pathology, especially in infants. Laparoscopy is safe and effective in the management of the MGD and ectopic ureter.

Epididymo-orchitis (EO) is a rare but important cause of scrotal swelling in pediatric patients. EO is caused by bacteremia leading to hematogenous seeding or ascending infection of the urinary tract. EO can be associated with abscess, bacteremia, and other serious infections, and must be distinguished from other causes of scrotal swelling such as testicular torsion. We present a case of a 16-day-old male with EO, scrotal abscess, and bacteremia from Escherichia coli.
