Solitary fibrous tumor/hemangiopericytoma of the penis

Large Solitary Fibrous Tumor (SFT) of the penis- a case report and review of literature

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.

Malignant solitary fibrous tumor of the penis: A case report of rare malignancy

Malignant Solitary fibrous tumor (SFT) is a rare mesenchymal tumor that consists of spindle cell components. The occurrence of SFT in the genitourinary tract is extremely rare. So, there is no clear algorithm for the management of this case. We report A 33-year-old male who complained of recurrent penile swelling in the last 7 months after underwent surgery 3 months earlier. The tumor re-enlarged from the surgical wound's previous sutures. Total penectomy was performed followed by bilateral inguinal lymphadenectomy. Perineostomy was performed for urinary diversion. Long-term follow-up after surgery is suggested due to the risk of recurrences and metastasis.

A Rare Case of Solitary Fibrous Tumour of the Pelvis in an 18-Year-Old Young Man: CT and MRI Features with Pathologic Correlations

Solitary fibrous tumors (SFTs) are mesenchymal neoplasms of fibroblastic origin, even if commonly seen in the pleura, they can occur anywhere in the body. SFT presents as a slow growing, often asymptomatic mass, generally affecting middle-aged adults regardless of the sex. We report a rare case of an 18-year-old man referred to our institution to perform computed tomography (CT) and magnetic resonance imaging (MRI), to investigate a pelvic mass incidentally discovered at abdominal ultrasound examination. A well circumscribed, heterogenous and hypervascular lesion was described at imaging, with absence of calcifications, hemorrhage, necrosis nor cystic degeneration. The mass removal was performed via the Da Vinci-assisted robotic surgery. Histopathological evaluation confirmed the diagnosis of SFT. CT and MRI can aid the identification of SFT, providing useful information which needs to be supported by histopathological analysis.
