Abstract Background: Schwannoma is a rare benign tumor of peripheral nerves arising from Schwann cells of the ubiquitous nerve sheath. Objective: To describe the operative steps and technical aspects of robotic laparoscopic resection of pelvic schwannoma. Methods: We describe 2 patients with pelvic schwannoma: a 34-year-old woman with schwannoma of the right lumbosacral trunk and a 58-year-old woman with schwannoma of a left S1 nerve. Pain was the main symptom in both patients. The diagnosis was confirmed by magnetic resonance imaging and nerve biopsies. Both patients were operated on by robotic laparoscopy. Results: Lesions were totally enucleated after incising the epineurium. After dissection of the schwannoma, the vascular pedicle and nerve fascicles involved were identified, coagulated, and then sectioned. The remaining fascicles of the nerve were preserved. The postoperative course was uneventful in both patients. With follow-up of 9 and 13 months, both patients obtained complete pain relief with no neurological sequelae. Conclusion: Robotic laparoscopic resection of pelvic nerve tumors such as schwannomas is technically feasible.

Background: PRMC is a very rare benign tumor of the abdominal cavity that usually occurs in women, and PRMC demonstrate no specific findings on CT. There are many reports on the differential diagnosis and discussion of PRMC imaging, but there are few reports on the treatment of dedifferentiated PRMC using laparoscopic resection and postoperative follow-up.

Atypical Presentations

Orbital schwannoma is a rare benign tumor, originating from the Schwann cells of the orbital peripheral nerve sheath. Orbital schwannoma is easily misdiagnosed if the patient shows atypical presentations and atypical appearance on MRI imaging. A 56-year-old male experienced hyposmia for 1 year and was misdiagnosed with cavernous hemangioma pre-operation. This case was treated by surgery through the endoscopic trans-nasal approach. After operation, the patient had no recurrence or complications. Preoperative diagnosis for these cases remains difficult. Combined imaging modalities including computed tomography (CT) and magnetic resonance imaging (MRI) can help in differential diagnosis. Surgery is the main treatment modality for treating orbital schwannoma. Outcomes in most cases are favorable without complications or recurrence.

Pseudotumoral calcinosis is a rare benign tumor, characterized by deep calcium deposition in peri-articular soft tissues. A numerous list of calcium deposit diseases exists making the calcinosis diagnosis very challenging. There are three principal forms or etiologies; primary or idiopathic forms followed by secondary forms due to chronic renal failure or hyperparathyroidism, then genetic forms such as Hyperphosphatemic Familial Tumoral Calcinosis (HFTC). We report a case of 14-year-old boy with primary tumoral calcinosis of the right hip. Total mass resection was performed without any recurrence at one-year follow-up.

Background: Hemolymphangioma is a rare benign tumor. To the best of our knowledge, there were only 10 reports of this tumor of the pancreas until March 2018. Case Report: Here, we reported a large invasive hemolymphangioma of the pancreas in a young woman with a complaint of abdominal distension and an epigastric mass about 3 weeks. She was found to have a huge multilocular cystic tumor at the neck and body of pancreas on computed tomography. She was eventually diagnosed with hemolymphangioma of the pancreas after operation. After 2 years of follow-up, there was no signs of recurrence. Conclusion: From our case and literature, we can conclude that hemolymphangioma of the pancreas is uncommon benign tumor, and it is hard to make an accurate diagnosis preoperatively. Radical surgical resection should be performed whenever possible. The prognosis of this disease seems good.

Benign phyllodes tumour (BPT) of the prostate is a very rare neoplasm. It is composed of hyperplastic and neoplastic glandular stromal proliferation. Patients with BPT of the prostate generally present with lower urinary tract symptoms and hematuria. BPT of the prostate can potentially cause recurrent obstructive symptoms. Complete transurethral resection (TUR) and close postoperative follow-up is recommended. A 59-year-old man presented with dysuria and obstructive urinary symptoms. Flexible cystoscopy revealed prostatic hyperplasia and a polypoidal lesion originating from the right lateral lobe of the prostate. Magnetic resonance imaging revealed a 3 × 2.5-cm mass lesion in the right lateral lobe of the prostate. TUR of the prostate was performed and the pathological examination revealed benign prostatic hyperplasia and benign phyllodes tumour of the prostate.

Eccrine syringofibroadenoma is a rare, benign tumor of eccrine ductal differentiation, typically presenting in the extremities. Herein we report a case of a 77-year-old man with pain in the lateral midfoot and the presence of an eccrine syringofibroadenoma lesion in the lateral heel. On surgical excision of the lesion, the foot pain promptly resolved, and at the most recent follow-up visit, the patient remained pain free.

A lipoma is a benign tumor, where the parenchyma is composed of adipose tissue. Lipomas comprise 0.1%–5% of all benign tumors in the oral cavity. A 43-year-old man, with a known masticatory disorder, visited the Department of Oral Surgery at our hospital because of a facial swelling. The swelling, which had worsened over 15 years, was not painful, but the patient had discomfort while eating and talking. A detailed examination revealed a smooth, elastic, soft, circular, and yellowish pink pedunculated tumor-like lesion, with a diameter of approximately 40 mm, on the right buccal mucosa. An oval-shaped neoplastic lesion with a well-defined border of 40   mm × 20   mm was noted on MRI. Based on these results, the lesion was characterized as being a benign lipoma. The tumor was resected under local anesthesia. The pedunculated tumor was excised with an electric knife, and the wound was sutured. No trismus or paresthesia was noted on the postoperative follow-up.

✓ The authors present the clinical, radiological, and pathological features of a malignant intracerebral nerve sheath tumor that occurred in the right parietooccipital lobe of a 4-year-old girl. Computerized tomography scanning and magnetic resonance imaging demonstrated a 5 × 5 × 4—cm multiloculated mass with considerable enhancement of the irregularly shaped septa and clearly calcified areas within the mass. Among five cases reported in the literature, this patient is the youngest and represents the first case in which there is radiological evidence of intratumoral calcification.
