Recurrent paratesticular liposarcoma: a case report

Introduction and importance

Paratesticular liposarcoma (PTL) is a rare condition, with fewer than 200 cases reported worldwide. It is a malignant tumor that originates from fat tissue with high risk of recurrence. Herein, the authors present a contralateral recurrence of a treated PTL. To the best of the authors' knowledge, in the current literature, there are few cases reported with recurrent PTL.

Case presentation

The authors report the case of a 62-year-old man who presented with a rapidly growing painless right hemiscrotal swelling. Clinical and radiographic evidence suggested the presence of two paratesticular tumors. The patient underwent a radical orchidectomy with resection of the two tumors through an inguinal approach. The histologic examination revealed a sclerosing, well-differentiated liposarcoma. The decision of the multidisciplinary consultation meeting was not to do adjuvant treatment. A follow-up of 12 months showed recurrence of the contralateral scrotum revealed by an FDG-PET/scan.

Clinical discussion

PTL, a rare spermatic cord tumor, affects adults aged 50-60, often presenting with scrotal swelling. Diagnosis involves ultrasound, computed tomography, and magnetic resonance imaging. Surgical intervention, including radical orchiectomy and adjuvant radiotherapy, is common for management, while the role of chemotherapy is inconclusive. High-grade subtypes carry a higher recurrence risk.

Conclusion

PTL is often misdiagnosed preoperatively. It is typically managed through radical orchidectomy, which includes wide excision and high ligation to ensure free surgical margins and avoid recurrence. The role of adjuvant therapy remains debatable. Despite a generally favorable prognosis, long-term follow-up is crucial because of the elevated risk of recurrence.

Fournier's gangrene revealing an acute arterial occlusion: A case report

INTRODUCTION AND IMPORTANCE

Fournier gangrene (FG) is a rare form of necrotizing fasciitis that affects both the deep and superficial layers of the perineal genital region. When left untreated, Fournier gangrene can rapidly advance, leading to substantial morbidity and mortality. Herein, we present a case of Fournier's gangrene, which revealed acute arterial occlusion. To the best of our knowledge, few cases of Fournier's gangrene secondary to arterial occlusion have been reported.

CASE PRESENTATION

We report the case of a 37-year-old man with no known medical history who presented with fever and painful swelling of the scrotum. Physical examination revealed a large black spot on the scrotum surrounded by erythema, suggestive of Fournier's gangrene. We performed an extended debridement of the scrotal area. Three days later, the patient complained of severe pain in the left foot accompanied by numbness. Lower limb computed tomographic angiography (CTA) revealed multiple arterial occlusions. Thrombectomy and anticoagulation therapy were crucial in managing the vascular thrombosis and preventing the further extension of the gangrene.

CLINICAL DISCUSSION

This case underscores the importance of recognizing diverse etiologies of Fournier's gangrene, including vascular involvement, and emphasizes the need for a multidisciplinary approach. Early identification, aggressive surgical debridement, and broad-spectrum antibiotics remain the cornerstone of management, with the added consideration of anticoagulation in cases involving vascular thrombosis.

CONCLUSION

FG is a rare yet potentially life-threatening condition. Its multifaceted etiologies, including vascular factors, underscore the complexity of its presentation and challenges for timely diagnosis. The recognition of vascular involvement as a potential etiology of FG warrants further in-depth exploration.
