“…Since hemangiopericytoma was first described in 1942 and solitary fibrous tumor in 1931; differentiation and classification of these two tumor types have been controversial. [7] Microscopically, presence of dilated and branching vessels and gene fusion between NAB2-STAT6, which results in overexpression of STAT6 protein, are common findings in both tumor types. [8] In 2013, World Health Organization (WHO) banned using the term hemangiopericytoma and hemangiopericytomas were classified as a part of extrapleural solitary fibrous tumors.…”

“…Authors suggest close follow up for at least five years for patients who had received a treatment for SFT-HMP in oral cavity, deep extremity, female genital tract, but a standard follow-up proposal is not available. [3,[7][8][9] Individual follow-up strategies usually include radiological studies and physical examination. At postoperative first year, we performed an abdominopelvic MRI and no local recurrence was detected.…”

Solitary fibrous tumor/hemangiopericytoma (SFT-HMP) is a rare spindle-cell mesenchymal tumor, thought to be of myofibroblastic origin. Penile SFT-HMP was mentioned in the literature in two separate case reports which were published in 2015 and 2017. We present the first case of SFT-HMP which is localized on corpus cavernosum of the penis. A 55-year-old man presented to our clinic with a small and gradually growing lesion on his penis for the past year, which recently caused difficulties during sexual intercourse. On physical examination; a well-shaped, nodular non-fluctuant, solid, painless mass, measuring 4x4 cm was palpated. Magnetic resonance imaging showed 5x5 cm mass located on the right corpus cavernosa. Under spinal anesthesia, surgical excision was performed. Pathologically, the tumor had an irregular architecture patterns and was characterized by hypercellular areas separated by thin-walled, branching vessels, lined with a single layer of flattened endothelial cells. SFT-HMP rarely occurs in genital tract and penile presentation is among the rarest. It should be classified and considered under penile masses, especially if the mass is well circumscribed, painless and slowly growing in nature. After differential diagnosis, surgical excision is mandatory.

“…Recurrence rates for SFT are substantial, with one meta-analysis demonstrating a range of 3%-22% recurrence for pleural SFT after surgical resection [ 12 ]. In head and neck SFT, wide margins can be difficult to achieve, and incomplete resection is associated with higher rates of recurrence and malignant transformation [ 13 ]. One site reported that no patients among a cohort of 14 with recurrent SFT were cured, despite complete salvage surgery of the first local recurrence; the researchers posited that local relapse is inevitably accompanied by dissemination [ 14 ].…”

Solitary fibrous tumors (SFTs) are rare soft tissue tumors that can arise in the abdomen, pleura, and central nervous system, among other sites. Surgical resection is the mainstay of management, although recurrence rates remain substantial. This case describes a 73-year-old male treated surgically for both a recurrent SFT and small bowel obstruction (SBO) secondary to adhesions. The patient had undergone numerous intra-abdominal operations for malignant SFT since 1994, highlighting the importance of meticulous resection at the initial presentation of local disease.

“…The unpredictable natural course of the disease coupled with rarity in its occurrence have dampened the development of standard management protocols, and thus, long term follow-up of patients being treated is essential in identifying key features and potential targets for surgical and systemic therapy respectively. Dilated and branching blood vessels, STAT6 protein overexpression and NAB2-STAT6 gene fusion are common to both hemangiopericytoma and SFT accounting for difficulties in differentiation and classification of these two entities [ 18 , 19 ]. Thus the World Health Organization (WHO), in 2013, discontinued the term heamangiopericytoma and reclassified it as part of extra-pleural solitary fibrous tumors [ 20 ] and in 2016 introduced the term SFT-HMP [ 21 ].…”

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.
