Primary Metastatic Squamous Cell Carcinoma of the Male Urethra Presenting with Scrotal Abscess and Subsequent Development of Fournier's Gangrene

Fournier's gangrene complicated by lower limb necrotising fasciitis and pelvic bone osteomyelitis: A case report with literature review

INTRODUCTION AND IMPORTANCE

Fournier's gangrene is a urological emergency associated with high mortality and morbidity. Severe gangrene resulting in pelvic bone and lower limb involvement are extremely rare.

CASE PRESENTATION

We report a rare case of Fournier's gangrene that is complicated by necrotising fasciitis of the lower limb and osteomyelitis of the pelvic bone, in a patient with previous prostatic adenocarcinoma. The patient was promptly resuscitated, started on broad spectrum antibiotics and then underwent an emergent surgical debridement, followed by multiple relook debridement and definitive reconstruction. Throughout the patient's hospitalisation, he was managed in a multidisciplinary team involving surgeons from different specialities, physicians and allied health staff.

CLINICAL DISCUSSION

Extension of Fournier's gangrene into distant structures is rare but serious complications. To date, there is only one other case reported in literature. The relationship between prior prostatic malignancy and Fournier's gangrene can be explored in subsequent studies.

CONCLUSION

We present a rare case of Fournier's gangrene with pelvic and distal limb involvement. We highlight the possible yet devastating complications of this disease and discuss treatment options available for the holistic management of patients with Fournier's gangrene.

Male Perineal Carcinoma: Experience in 4 Cases and Literature Review

Perineal carcinoma of unknown origin is a rare and aggressive disease, so an early diagnosis and adequate treatment are essential to prevent its progression. We report the first series of cases of perineal carcinoma of unknown origin: (I) a 62-year-old male patient being followed up for a urethral stricture treated with periodic dilations with subsequent development of perineal abscesses and perineal carcinoma; (II) a 67-year-old male patient who consults for urinary discomfort associated with a perineal abscess. Recurrence of the abscess in the first month revealed the presence of an underlying perineal carcinoma; (III) a 78-year-old male patient that underwent urethroplasty with graft with subsequent regimen of periodical dilations. Recurrent formation of perianal abscesses revealed the presence of an underlying perineal carcinoma; and (IV) a 78-year-old male patient with history of in situ penile carcinoma treated by glans resurfacing. He consulted for penile pain, and imaging tests revealed a perineal abscess adjacent to the left corpus cavernosum. The core needle biopsy revealed a squamous cell carcinoma. Penile exploration and negative glans biopsy ruled out possible recurrence of penile carcinoma. The form of presentation of the disease has been very similar in all patients, demonstrating the presence of perineal abscess in all cases. Two patients had inguinal lymph node disease at diagnosis. All patients were treated by surgery, and three of them required adjuvant systemic treatment. Surgery combined with systemic treatment is probably the best option if the patient’s conditions allow it.

Non-mucinous adenocarcinomas and squamous cell carcinomas of the anal region masquerading as abscess or fistula: a retrospective analysis and systematic review of literature

PURPOSE

Abscess or fistula of the anal region is an uncommon presentation of malignancy. Under the assumption of a benign condition, diagnostics is often delayed, resulting in advanced tumour stages at first diagnosis. Due to the case rarity, treatment guidelines for cancers of anorectal region masquerading as abscess or fistula are missing.

METHODS

We analysed all patients presenting with an abscess or fistula of the anal region in our department between January 2004 and August 2020. The malignancies were included to our study to acquire data on clinical presentation, treatment and outcome. Furthermore, a systematic review to present adenocarcinomas and squamous cell carcinomas associated to an abscess or fistula was performed.

RESULTS

0.5% of the patients treated for an abscess or fistula of the anal region met the selection criteria. Mean time from the onset of symptoms to diagnosis of malignancy was 100 days. Histology revealed adenocarcinoma and squamous cell carcinoma each in two patients. All patients had locally advanced tumours without distant metastases, in two cases with regional lymph-node metastases. Neoadjuvant chemoradiation was applied in two patients. All patients underwent abdomino-perineal resection of the rectum. The overall outcome reveals a recurrence-free survival of 4.5 and 3 years for two patients. Further two patients died within 5 months after the primary resection.

CONCLUSION

Advanced carcinomas of the anorectal region may masquerade as abscess or fistula, cause diagnostic problems and delay oncologic treatment. However, even in these very advanced situations, surgical therapy with curative intent should be attempted.

Fournier's Gangrene in the Setting of Underlying Carcinoma: A Case Report and Review of the Literature

Most case series of Fournier's gangrene (FG) do not list malignancy as a cause; however, isolated cases with underlying malignancy of the soft tissue, genitourinary, and gastrointestinal systems have been described. After a review of recently published literature, 20 case reports and 15 case series or review articles included relevant information and were included in this literature review.

Malignancy is overlooked in 10% (2/20) of patients, resulting in a delayed diagnosis and initiation of cancer treatment. All patients with FG should have a thorough cancer history, digital rectal examination, appropriate local and systemic imaging, as well as tissue biopsies, to reduce the likelihood of a missed cancer diagnosis. Delay in management of the local malignancy may lead to persistence or recurrence of the infection and significantly worsens overall outcome and survival.

[Rare causes of acute purulent-inflammatory lesions of pararectal tissue and Fournier's gangrene]

National and foreign literature devoted to acute non-cryptogenic suppurations of pararectal tissue was analyzed. Own clinical observations are given. The unsolved questions of terminology and treatment strategy for this rare disease are discussed.

Primary male urethral squamous cell carcinoma presenting with a genital abscess

Introduction

Primary urethral cancer is a rare disease accounting for <1% of all urological cancer cases. We encountered a patient with urethral squamous cell carcinoma diagnosed during treatment of a genital abscess.

Case presentation

A 69‐year‐old male was referred to our hospital for recurrent urethritis and swelling of the scrotum. The genital skin was atrophic with a purulent discharge. A diagnosis of epididymitis‐induced genital abscess was made, and conservative treatment was administered. However, local infection recurred and the infected tissue was resected 4 months after the first examination. The pathological diagnosis was squamous cell carcinoma. Subsequently, radical surgery was performed, but the patient died 17 months postoperatively.

Conclusion

Four patients with primary urethral squamous cell carcinoma presenting as genital abscess have been reported. Careful examination is necessary while considering a malignant tumor as an underlying disease.

First report of urethroscrotal fistula in patients under 5 years of age presenting as recurrent scrotal swelling

Urethroscrotal fistula is a very rare pathology and is divided into congenital and acquired types. Herein we report a 4.5-year-old child with recurrent scrotal swelling and final diagnosis of urethroscrotal fistula. Clinicians should be aware and consider this disease in the differential diagnosis of any scrotal swelling, especially recurrent type. As far as we are aware, this is the first report of urethroscrotal fistula in patients under 5 years of age.
