Oral neurothekeoma or nerve sheath myxoma is a rare benign oral tumour of nerve sheath origin. Historically, this tumour has been subclassified as myxoid (classic), mixed, or the cellular type, depending on the amount of myxoid stroma and cellularity. We present a case of oral neurothekeoma (mixed type) of the buccal mucosa. The tumour was completely excised. No recurrence was detected in the last 3 years after local excision.

Abstract OBJECTIVE AND IMPORTANCE Schwannomas occurring in the neuraxis are very rare. Usually, these tumors are benign. Primary malignant intracerebral nerve sheath tumors are extremely rare, with only five documented cases in the international literature. We report one case of a primary malignant intracerebral nerve sheath tumor occurring in the right cerebral peduncle of a 35-year-old man. CLINICAL PRESENTATION Magnetic resonance imaging revealed a heterogeneous peripherally enhancing mass of the right cerebral peduncle, surrounded by a small edema. INTERVENTION Unlike the five cases previously reported, this is the first time a stereotactic biopsy has been performed, and this is the only patient who responded to cranial radiation therapy for approximately 2 years. When the tumor recurred, a systemic chemotherapy treatment was prescribed. No positive response was seen, and the patient died 29 months after the initial diagnosis. CONCLUSION An accurate diagnosis and planned aggressive treatment seem to be the key elements in the management of the disease.

Necessary and sufficient conditions on weight pairs guaranteeing the two-weight inequalities for the potential operators(Iαf)(x)=∫0∞(f(t)/|x−t|1−α)dtand(ℐα1,α2f)(x,y)=∫0∞∫0∞(f(t,τ)/|x−t|1−α1|y−τ|1−α2)dtdτon the cone of nonincreasing functions are derived. In the case ofℐα1,α2, we assume that the right-hand side weight is of product type. The same problem for other mixed-type double potential operators is also studied. Exponents of the Lebesgue spaces are assumed to be between 1 and ∞.

Carcinoma Buccal Mucosa

Adenoid cystic carcinoma is a malignant neoplasm most commonly originating in the minor salivary glands of head and neck region. Among intra oral adenoid cystic carcinoma, buccal mucosa is one of the rarer sites. Here, we report a case of recurrent adenoid cystic carcinoma of the right buccal mucosa in a 33 year old female. As this is an uncommon site for adenoid cystic carcinoma, it should be considered as a differential diagnosis of mass of buccal mucosa. It is imperative that we identify such cases and plan for early surgical excision with adequate margins.

Introduction. Liposarcoma is a rare pathological entity. By far it is the most common histological subtype of genitourinary sarcomas in adults. Approximately two hundred cases were reported in the literature. We are hereby presenting a case with a typical clinical scenario of paratesticular liposarcoma.Case report. A 75-year-old gentleman presented with a painless right hemiscrotal swelling that was progressively increasing in size over the last 6 years. Testicular tumour markers were negative. Imaging showed a heterogenous mass with fat component. Subsequently he underwent wide local excision that included the paratesticular mass along with the right testicle and all right inguinal canal contents up to the deep inguinal ring with the sparing of right illioinguinal nerve. Histopathological examination showed a well differentiated liposarcoma of the spermatic cord. He remained recurrence-free so far after 18 months of followup.Conclusion. Radical orchidectomy with wide local excision comprises the cornerstone of treatment of paratesticular liposarcoma. Due to the rarity of the disease there is no definite universal consensus of opinion as regards the role of radiotherapy and chemotherapy.

Primary malignant peripheral nerve sheath tumors (MPNSTs) are extremely rare in patients without a history of neurofibromatosis; only 18 cases have been reported in the English-language literature to this point. The authors report their experience with 1 new case of a primary MPNST. A 33-year-old woman presented with low-back pain radiating to the right calf that progressed over 1 year. Magnetic resonance imaging of the spine revealed an intradural extramedullary lesion at the T12–L1 level. The patient was diagnosed with primary MPNST, underwent two surgical excisions and radiation therapy, and developed leptomeningeal metastases as well as brain metastases. The patient revisited the emergency room with sudden loss of consciousness. A brain CT scan displayed bilateral lateral ventricle enlargement, for which a ventriculoperitoneal shunt was inserted. These symptoms have not been described in any previous report. Primary spinal MPNST is an exceedingly rare entity, and the overall prognosis is very poor. To the authors' knowledge, no standard of care for primary spinal MPNSTs has yet been established. All 19 cases of primary spinal MPNSTs are reviewed, and the authors discuss their clinical, radiological, and therapeutic features and outcomes.

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.
