Subacute Urinary Retention due to a Subpubic Cartilaginous Cyst Treated with Surgical Resection and Internal Fixation: A Case Report and Review of the Literature

Rare case of retropubic parasymphyseal cyst in a male patient

INTRODUCTION

Retropubic parasymphyseal cysta are rare, and few cases have been reported in men.

CASE PRESENTATION

A 65-year-old male patient presented with a 6-month history of pelvic and perineal pain. Magnetic resonance imaging revealed a high-intensity, irregular-shaped mass extending from the pubic symphysis to the bladder. Contrast enhancement revealed no uptake in the central part of the mass, indicating a cystic component. Computed tomography showed erosion of the pubic symphysis and pubic osteophytes. Pathological findings of biopsy specimens revealed inflammatory fibrous tissue but no malignancy. The definitive diagnosis was retropubic parasymphyseal cyst associated with inflammation. The patient was treated with cefazolin from 1 day before surgery until postsurgical day 7. Oral antibiotic therapy was then prescribed for 1 month to maximize treatment. After 2 months, the patient's symptoms resolved.

CONCLUSION

Retropubic parasymphyseal cysts with inflammation and smaller asymptomatic cysts can be managed effectively with conservative or minimally invasive treatment.

An unusual case of vaginal mass - subpubic cartilaginous cyst

Subpubic cartilaginous cyst is a rare form of ganglion cyst that arises on the inferior surface of the pubis symphysis. The pathophysiology is poorly understood but has been hypothesised to be secondary to mucinous degeneration of the pubic supporting ligaments with cartilaginous metaplasia. We report a case of subpubic cartilaginous cyst in a 58-year-old woman who presented with an unusual symptomatic vaginal mass, that she described as ‘growing a penis’. The patient proceeded to surgical excision of the lesion and is symptom and recurrence free following 2.5 years of follow up.

Three female patients with a periurethral mass: from various complaints to rare pathology

In this case report, we will discuss three cases of women diagnosed with a periurethral mass. The specific diagnosis of a periurethral mass can vary and includes rare diseases. Therefore, they provide a challenge to medical professionals. All patients underwent diagnostic evaluation with cystoscopy and pelvic MRI followed by surgical removal. Based on the MRI and pathology report, different diagnoses were made for each patient. The three diagnoses will be discussed: subpubic cartilaginous cyst, leiomyoma and clear cell adenocarcinoma of the urethra. Our case report is useful for other medical professionals, and they can evaluate how to optimal approach a periurethral mass.
