Robot-Assisted Laparoscopic Renal Schwannoma Excision

Renal Schwannoma: A Rare Case Report and Literature Review

Schwannomas originating in the kidney are extremely rare with very few cases documented in the literature. It is difficult to distinguish them from other common renal masses based on clinical symptoms and imaging characteristics alone, as both are non-specific for this pathology. Thus, the final diagnosis of schwannoma is typically made only after surgical resection and histologic examination. We present the case of a 66-year-old female who was initially evaluated for flank pain and referred to us after a renal mass was found on CT imaging. A partial nephrectomy was performed, and subsequent pathological examination confirmed the diagnosis of renal schwannoma.

Renal schwannoma: A case report and literature review of a rare and benign entity mimicking an invasive renal neoplasm

Schwannomas of the kidney are rare with only a handful of cases reported in literature. We present a case of a large Schwannoma of the right kidney causing mass effect with imaging characteristics thought to represent renal cell carcinoma. On imaging, these masses present similarly to solid renal masses and are therefore indistinguishable without tissue diagnosis. Thus, surgical resection is the definitive treatment for renal schwannomas.

•

Schwannoma of the kidney is a rare entity.

•

Schwannoma of the kidney presents similarly to renal cell carcinoma on imaging.

•

Schwannoma of the kidney can present as large renal masses exerting mass effect.

•

Surgical resection is indicated to confirm diagnosis of Schwannoma of the kidney or renal cell carcinoma.

Retroperitoneal robot-assisted resection of a lower posterior mediastinal benign schwannoma using a transdiaphragmatic approach: A case report

INTRODUCTION

Neurogenic tumors are the most frequent neoplasms of the lower posterior mediastinum. Traditionally, lower posterior mediastinal tumors are excised by video-assisted thoracic surgery. However, the available robotic treatment for the lower posterior mediastinum tumors to date are rare. Herein, we report a case of a right lower posterior mediastinal tumors successfully treated with retroperitoneal robot-assisted surgery using a transdiaphragmatic approach.

PATIENT CONCERNS

A 54-year-old male patient without any symptoms was admitted into our department with a right lower posterior mediastinal paravertebral tumor that was detected during a medical check-up.

DIAGNOSIS

A right lower posterior mediastinal paravertebral tumor.

INTERVENTIONS

Retroperitoneal robot-assisted resection using a transdiaphragmatic approach was performed.

OUTCOMES

The patient was treated with retroperitoneal robot-assisted surgery using a transdiaphragmatic approach and remained disease-free throughout a 6-month follow-up. His postoperative course was uneventful. Histopathological examination revealed a benign schwannoma.

CONCLUSION

Our initial experience showed that retroperitoneal robot-assisted resection of a lower posterior mediastinal tumor using a transdiaphragmatic approach is technically feasible and can be considered a potential alternative for either video-assisted thoracic surgery or a thoracotomy.

Benign renal schwannoma: Case report and literature review

Renal schwannoma is a very infrequent tumor. It is usually benign and it does not have any specific symptoms or imaging characteristics. Its final diagnosis is usually made after surgery. We present a 66 year-old-man that was referred to our center after the casual finding of a renal mass. With a suspected diagnosis of a renal cell carcinoma, a partial nephrectomy was performed. The histological study revealed the final diagnosis of a benign renal schwannoma.
