Background
Solitary fibrous tumors (SFTs) are very rare spindle cell neoplasms of mesenchymal origin with largely benign course of disease. Genital SFT’s can be managed providing excellent functional and psychological outcomes by timely intervention.
Case presentation
We report the largest and possibly the second only reported case of penile SFT in a 34 year male presenting with a gradually increasing perineal mass with clinically normal appearing phallus. MRI revealed a 9.8 × 3.2 cm soft tissue mass arising from left corpora cavernosae, the mass was excised en-bloc via a perineal approach under spinal anaesthesia. Histopathology revealed spindle cell tumor embedded in myxohyaline stroma along with hyalinized vascular channels demonstrating IHC positivity for CD34 and STAT6. The patient is disease free post 2 years of resection with no sexual or urinary dysfunctions.
Conclusion
Genital SFTs, although rare, should be considered in the differential diagnosis of well-circumscribed, painless, slow growing solid masses and histopathologists must be vigilant of its malignant characteristics.
Introduction: Dorsal onlay urethroplasty with Buccal Mucosal Graft (BMG) is the single stage procedure and is most commonly used to treat long segment anterior urethral strictures. Unilateral mobilisation of the urethra prevents both chordee and ischaemia. Aim: To evaluate the feasibility, medium-term and long-term outcomes of dorsal onlay BMGs when used to treat long anterior segment penile urethral stricture with unilateral mobilisation of the urethra. Materials and Methods: A retrospective study was conducted in Kasturba Hospital, Manipal, Karnataka, India, from January 2008-December 2018. A total of 56 patients with long anterior segment penile urethral strictures underwent BMG substitution for urethroplasty, with a follow-up period ranging from 1.2-10 years. The outcome of the procedure was assessed through clinical history and physical examination, uroflowmetry, retrograde and voiding cystourethrography and urethroscopy {6 French gauge (Fr)}. Statistical analysis was performed using the mean and median. Results: The mean age of 56 patients was 51.8±9.9 years, with a mean±Standard Deviation (SD) Maximum Flow Rate (MFR) of 20.1±5.3 mL at one month and 18.1±4.3 mL at three and 18.7±3.7 mL six months, 17.3±5.1 mL, 19.3±4.3 mL and 18.6±3.7 mL at one year, 2-5 years and 10 years postoperative respectively. Postvoid Residual urine (PVR) volume was higher till one year follow-up (i.e., 1st month it was 38.6±23.6 mL in 47 patients, 3rd month it was 45.8±22.4 mL in 12 patients, 6th month it was 49.0±28.8 mL in 14 patients and one year follow-up it was 43.9±30.8 mL in 24 patients). Minimal complications were noted over 5-10 years follow-up. Conclusion: For long segment anterior penile urethral strictures, unilateral mobilisation in BMG urethroplasty had shown success over both medium and long-term periods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
