MR imaging of the penis: What a radiologist needs to know!

Magnetic resonance imaging (MRI) plays an important role in imaging of penile pathologies due to its excellent soft tissue resolution and multiplanar imaging capabilities. This imaging review describes the MRI protocols and anatomical considerations in penile pathologies. MRI not only serves as a complementary tool to ultrasound in evaluation of trauma, infections, inflammatory diseases, and malignancies, but is also used as the definitive imaging modality for evaluation of penile prosthesis and complex cases.

Clinicopathological Findings and Comprehensive Review of Buschke-Lowenstein Tumors Based on a Case Study

The Buschke-Löwenstein tumor (BLT), also known as giant condyloma acuminatum, is a rare, exophytic tumor, arising from pre-existing warty lesions associated with human papillomavirus (HPV) infection, particularly strains 6 and 11, which are considered to have low oncogenic potential. BLT presents as a large, cauliflower-like growth typically affecting the penis, vulva, vagina, perineum, scrotum, anus, and perianal area. Despite being a benign lesion, BLT is locally aggressive with a high recurrence rate, and can potentially undergo malignant transformation into squamous cell carcinoma, contributing to an overall mortality rate of 20-30%. The primary treatment is complete surgical excision with wide margins, frequently requiring complex reconstructive techniques for defect coverage. We report on a 68-year-old patient, with multiple comorbidities, who presented with a two-year history of a large exophytic tumor in the genital region, affecting the penis, along with progressive erectile dysfunction and urinary problems. The tumor was surgically excised with oncological safety margins, and reconstruction was performed using advancement and rotation flaps from the scrotum and intact penile skin. Histopathological examination confirmed the diagnosis of Giant Condyloma (Buschke-Löwenstein tumor), showing acanthosis, papillomatosis, parakeratosis, and koilocytic cell collections, with positive immunohistochemical staining for p16, p63, and ki67. Postoperatively, the patient had a good clinical outcome and a complete surgical cure. This case highlights the critical need for timely intervention and comprehensive management strategies in treating giant condyloma, given its potential for local invasion and substantial impacts on patient quality of life. Early diagnosis and thorough surgical excision are crucial for effective management and to reduce the high recurrence, morbidity and malignant transformation risk associated with this condition.

Buschke-Lowenstein tumor in the penis and anorectal region: case report

The Buschke-Lowenstein Tumor is a giant condyloma acuminatum caused by human papillomavirus, most commonly types 6 or 11. It is a rare condition with an estimated frequency of 0.1% in the general population. Transmission primarily occurs through sexual contact. It particularly affects men, predominantly appearing on the penis, characterized by its deep-seated growth, potential for degeneration, and tendency to recur after treatment. Surgery is the preferred treatment. We present the case of a50-year-old patient with a history of recurrent urethritis and multiple sexual partners. The patient sought medical attention for a swelling on the penis that had been progressively developing over the past 10 years. An MRI was performed for a locoregional study, revealing a perineal and penile mass with polylobed contours resembling a cauliflower, along with a sizable perineal mass Histological examination of a biopsy sample from the penis confirmed the diagnosis. Unfortunately, due to the tumor's characteristics and the patient's condition, surgery was contraindicated.

Buschke-Löwenstein tumour: a rare and challenging entity

Buschke-Löwenstein tumour (BLT) is rare and locally aggressive, and malignant transformation is a possibility. Because there is no consensus on the best treatment approach, the authors present a treatment algorithm based on several case reports. A 57-year-old male patient resorted to surgical consultation with a giant perianal cauliflower-like mass. A BLT was diagnosed. Due to the involvement of the anal sphincter, a wide local excision saving the rectum failed. Abdominoperineal resection was performed. Malignant transformation was diagnosed, and adjuvant radiotherapy was delivered. Clinical evolution was uneventful. Aggressive behaviour despite the absence of malignancy is the hallmark of BLT. The common presentation is an anal mass with a cauliflower-like appearance. Anal verrucous carcinoma and squamous cell carcinoma are the major differential diagnoses. BLT treatment is challenging. Surgery is the first-line treatment, raging from wide local excision to abdominoperineal resection. To improve outcomes, chemoradiation can be used in combination with surgery. Long-term follow-up is mandatory.

Structure, Genome, Infection Cycle and Clinical Manifestations Associated with Human Papillomavirus

A small, non-enveloped, obligatory parasite, Human papillomavirus (HPV) is known to be the cause of a range of malignancies. These entail benign infections like genital warts as well as malignant, life-threatening conditions such as cervical cancer. Since a very high mortality rate is associated with HPV caused cancers (cervical cancer is a 2nd leading cause of death caused due to cancer among women globally), there is an escalating need to understand and search for ways to combat such medical conditions. Under the same light, the given article provides an insight into the world of this versatile pathogen. Distinct aspects related to HPV have been discussed here. Emphasis has been laid upon the composition, function and assembly of capsid proteins (structural studies) and various genetic elements and their gene products (genomic studies). The essence of the mechanism behind the development of persistent infection and modes responsible for the transmission of the infectious particles has been briefly covered. Finally, the review outlines various infections and diseases caused by HPV with a major focus on their clinical and histological manifestations.

Buschke–Löwenstein tumor of the penis

Background

The Buschke–Löwenstein tumor comes from the confluence of multiple condyloma acuminata and is clinically manifested by warty, exophytic, ulcerated lesions, with aggressive behavior, rapid growth, invasion and destruction of adjacent structures.

Case presentation

A 57-year-old man with type II diabetes mellitus, high blood pressure and a history of high-risk sexual behavior with multiple partners was evaluated in the urology department for multiple penile lesions of verrucous appearance and fetid odor of 10 months of evolution. Biopsy of the lesion was performed revealing a giant condyloma acuminatum.

Conclusions

Radical surgical excision with wide surgical margins remains the first line of treatment. Close follow-up of these patients is crucial given the complexity and tumor recurrence.

Successful nonsurgical treatment of penile Buschke-Löwenstein tumor with 12 weeks of 5% imiquimod alone

Anogenital warts, also known as condylomata acuminata caused by human papillomavirus constitute the most common sexually transmitted infection. Rarely, the disease may evolve into a huge cauliflower-like growth called giant condyloma acuminatum or Buschke–Löwenstein tumor (BLT). In contrast with normal anogenital warts, BLT displays local invasion, lack of spontaneous resolution, posttreatment recurrence, and potential for malignant transformation. Although radical excision with split-thickness skin grafting is considered its first-line treatment, it is not always feasible. While many other treatments have shown variable success and recurrence rates, topical imiquimod 5%, a popular evidence-based therapy for warts has also been reported as an efficacious treatment for BLT. We present a case of penile BLT where the patient refused surgery but recovered completely with no recurrence at five years following 16 weeks’ therapy with topical 5% imiquimod. Excepting a single reported case, this might be another case where BLT resolved with imiquimod as a standalone therapy. We also present a succinct review of past cases of BLT treated with imiquimod.

Malign Differentiation of a Large Buschke Loewenstein Tumor in Penis

Buschke-Loewenstein tumor (BLT) is a giant condyloma acuminatum which is very rare and commonly affects the anogenital region. The malignant transformation and localization in penis is very rare. This article aims to present a case with BLT with malignant transformation in penis. A 59-year-old male patient was referred, who has have been suffering from a cauliflower-like lesion in the penis for 8 years. Biopsies revealed a BLT with malignant transformation. The lesion was excised largely and reconstructed with local flaps and skin grafts. Defined by Buschke and Loewenstein in 1925, giant condyloma acuminatum is a rare and important disorder because of the sexually transmitting capability.

A case of penile Buschke-Lowenstein tumor in a developing country

Buschke-Löwenstein tumor is a rare manifestation of a sexually transmitted human papilloma virus infection that affects the anogenital area. Wide local excision of the lesion is the mainstay of treatment. Malignancy though must be excluded.

Ano-Genital Warts and HIV Status- A Clinical Study

INTRODUCTION

Ano-Genital Warts (AGW) like other Sexually Transmitted Diseases (STD) is associated with Human Immunodeficiency Virus (HIV) infection. This study of AGW was done in HIV positive and HIV negative patients.

AIM

To study the risk factors and clinical presentations of ano-genital warts in HIV positive and negative patients.

MATERIALS AND METHODS

A comparative, cross-sectional, descriptive study of 25 HIV positive and 25 HIV negative (n=50) AGW patients between 15-60 years of both sex was conducted in Dr. D. Y. Patil Hospital and Research Centre from July 2014 to July 2016.

RESULTS

Significant association of HIV positivity (p<0.05) was observed between age group of 15-30 years and HIV negative status (p<0.05) in age group of 31-45 years. HIV positive status significantly higher in patients with self-admitted multiple sexual partners (p<0.01), homosexuality (p<0.05) and presentation with anal warts (p<0.01). HIV negative status correlated significantly with single sexual partner admission (p<0.01) and hetero-sexuality (p<0.05). Gender did not show significant association with number of sexual partners or HIV positivity. Extra-genital or only genital warts had no association with HIV status. Co-STDs though more in number in ser-positive group, did not show any significant association with HIV positivity (p>0.05). No patient presented with changes of malignancy. Four were adolescents below 19 years. Two patients had atypical presentations of giant condylomata i.e., Buschke-Lowenstein Tumour (BLT).

CONCLUSION

HIV positivity was significantly associated with the risk factors of age below 30 years, homo sexuality and multiple sexual partners. Anal warts were significantly common in HIV positive patients. Four adolescents with AGW underline the need for high risk behaviour counselling. No patient had malignant ano-genital warts. Follow up of these patients with Human Papilloma Virus (HPV) sub-typing is necessary.

Invasive squamous cell carcinoma originating from a giant penile condyloma

In this case study, we present an unusual case with squamous cell carcinoma originating from a giant condyloma acuminata completely surrounding the penis. A 57-year-old circumcised heterosexual male patient presented with a penile lesion existing for 20 years. Incisional biopsy revealed acanthosis of the squamous epithelium. The patient was operated on under spinal anaesthesia. The lesion was resected circumferentially with macroscopic clearance, resulting in complete degloving of the penile shaft. Neurovascular bundles were preserved. The penile skin was constructed with a split thickness skin graft. Histopathological analysis of the lesion revealed an invasive and well-differentiated squamous cell carcinoma arising on a condyloma, and the surgical margins were free from tumour. The patient was staged as G2 T1 N0 M0 and was followed for one year. He did not have any erectile dysfunction and could engage in intercourse. Pelvic tomographic and physical examination findings did not reveal any episode of recurrence or metastasis. When encountering patients with giant condyloma acuminata, it should not be forgotten that it may be accompanied by squamous cell carcinoma. In addition, tissue excision should be as extensive as possible while keeping in mind the importance of the function. This is the first case of a penile-degloving surgery for giant penile condyloma, supporting conservative and preserving penile surgery for such tumours.

Buschke-Löwenstein Tumour: Successful Treatment with Minimally Invasive Techniques

We report a case of an 80-year-old female who presented with a four-year history of a growing mass in the perianal area with pain and bleeding during defaecation. Clinical examination revealed a locally destructive, cauliflower-like, verrucous mass measuring 10 × 12 cm in diameter. Histologic findings revealed a moderate degree of dysplasia of the epithelium with koilocytosis atypia, acanthosis, and parakeratosis, features that are consistent with Buschke-Löwenstein tumour. Polymerase-chain-reaction assay for human papillomavirus (HPV) showed an infection with HPV type 11. Full-thickness excision of involved skin was undertaken by cryotherapy and electrocautery over five months. The entire wound was left open to heal by secondary intention. After 3 years of follow-up, the patient has not experienced a recurrence, with excellent functional results, but the cosmetic results were satisfactory. These minimally invasive techniques can be safer and more cost-effective than surgery and the General Practitioner can play a key role in diagnosis.

Electrocautery resection, shaving with a scalpel, and podophyllin: a combination therapy for giant condyloma acuminatum

Giant condyloma acuminatum (also known as Buschke-Löwenstein tumor) is a rare disease, for which the treatment of choice is still controversial. In the case described in this report, we used a combination of electrocautery and a surgical scalpel to resect a huge genital wart, followed by long-term local treatment with podophyllin. This procedure was relatively fast, easy to perform, involved minimal bleeding, and did not result in any complications. Moreover, combination therapy enabled us to avoid deep resection of the lesion and consequently, sexual function was preserved completely.
