Progression of Intravesical Condyloma Acuminata to Locally Advanced Poorly Differentiated Squamous Cell Carcinoma

[Development of a squamous cell carcinoma of the urinary bladder after intravesical condylomas]

BACKGROUND

The occurrence of intravesical condylomata acuminata has been described as a fairly uncommon, benign epithelial lesion. Reports on progression into a muscle-invasive carcinoma of the bladder are rare.

CASE

We present the case of a 68-year-old man who had a history of intravesical condylomata acuminata over several years and developed a muscle-invasive squamous cell carcinoma of the bladder. Having undergone several transurethral resections, but failed to receive intravesical instillation therapy or continuous follow-up examinations, the patient visited our department. After being diagnosed with ichthyosis vesicae, the patient had a rapid disease progress and developed a muscle-invasive squamous cell carcinoma of the urinary bladder within 3 months. He underwent radical cystectomy.

SUMMARY

The carcinogenic potency of the human papilloma virus is well known for carcinomas of the male and female genitals. The occurrence of intravesical condylomata is rare. They are commonly perceived as benign lesions and, therefore, mainly treated symptomatically. Our case shows that progression to a highly aggressive muscle-invasive squamous cell carcinoma is possible.

CONCLUSION

The diagnosis of intravesical condylomata acuminata requires stringent urologic follow-up examinations including biopsy of suspicious lesions and stage-appropriate surgical management in the case of an invasive carcinoma.

Intravesical ichthyosis: a rare case report

BACKGROUND

Ichthyosis is a rare skin disorder, in which the shedding of squamous cells is altered. Intravesical ichthyosis is an extremely rare condition. There is evidence for an association with intravesical condylomata accuminata, caused by urogenital infections of the human papilloma virus. These lesions are generally benign but known to be of a carcinogenic potential and therefore should be treated immediately and followed-up closely.

CASE PRESENTATION

We present the case of a 39-year-old woman who presented with recurrent urinary tract infections. During cystoscopy diffuse black pigmented flat bladder tumours were visualized. After transurethral resection the pathological report diagnosed an ichthyosis vesicae.

CONCLUSION

We recommend a complete resection with frequent clinical and cystoscopic follow-up. Furthermore, testing for the human papilloma virus should be performed and a vaccination should be offered to the patient. As ichthyosis vesicae is a rare phenomenon, there is an evident lack of clinical data regarding therapy, prognosis and follow-up. With our report, we want to emphasize the need for further research.

Intravesical Condyloma Acuminata Progressing to Squamous Cell Carcinoma of the Bladder: An Unusual Presentation

Squamous cell carcinoma (SCC) of the bladder resulting from condyloma acuminata (CA) is uncommon. Most cases of SCC are asymptomatic until an advanced stage making the diagnosis difficult. Most patients present with urinary symptoms. We present the case of a 31-year-old African American male who presented to the emergency department with right lower extremity deep vein thrombosis. His past medical history was significant for recurrent bladder and urethral CA with high-grade dysplasia. A computed tomography (CT) gave the incidental findings of pelvic and bladder masses. The masses were studied and came back concerning for malignancy. The patient will undergo surgical removal soon. This manuscript illustrates an unusual presentation of CA progressing to SCC, including the diagnostic approach and treatment. We hope to increase awareness of the clinical presentation and regular follow-up in patients with risk factors.
