Background: Lipoma is a benign neoplasm originated from adipose cells circumscribed by connective tissue. This neoplasm represents about 1% to 4.4% of all oral benign tumors and it is rarely located in the palate area. Objective: This case reports the occurrence of an oral lipoma in the hard palate of a 57-year-old woman and discusses its etiology and treatment. Case Report: The treatment consisted in the total resection of the lesion and laser therapy. The patient is being followed up for forty three months with no signs of recurrence. Conclusion: Lipoma in hard palate is a rare entity that may be associated with endocrine factors and local inflammation.

AbstractIntracranial schwannomas (ICS) unrelated to the cranial nerves are extremely rare; around 70 cases have been reported worldwide. The available literature consists of case reports and small series that present variable characteristics distinguishing these lesions. Brain parenchyma schwannomas are typically benign tumors with currently unknown origins. Diagnosis of intraparenchymal schwannoma is almost never made preoperatively. The management of these tumors usually consists of gross total resection, chemotherapy, and radiotherapy in cases of recurrence. The authors present a case of fractionated Gamma Knife radiosurgical treatment of intracerebral schwannoma following partial microsurgical resection.

AbstractSchwannomas are benign tumors, which arise from the Schwann cells of the central or peripheral nerves. They form 8% of all intracranial tumors and most of the cases arise from vestibular division of the 8th cranial nerve. Rare cases are shown to arise from the olfactory or optic nerve, being devoid of myelin sheath. Up to date and according to our best of knowledge, 66 cases have been reported till now. Here we present a review of the literature and a case report of a 56-year-old male with an accidently discovered anterior cranial fossa schwannoma, following a road traffic accident. Tumor was completely excised, using a right frontal approach. Histopathology revealed Antoni-A cellular pattern. Although rare, but olfactory nerve schwannomas should be included in the differential diagnosis in anterior cranial fossa space occupying lesions, and the approach should be designed taking into consideration, this rare entity.

Initial Symptoms

Abstract Background Ganglioneuromas (GNs) are extremely rare, slowly growing, benign tumors that can arise from Schwann cells, ganglion cells, and neuronal or fibrous tissues. Due to their origin from the sympathetic neural crest, they show neuroendocrine potential; however, most are reported to be hormonally inactive. Nevertheless, complete surgical removal is recommended for symptom control or for the prevention of potential malignant degeneration. Case Report A 30-year-old female was referred to our oncologic center due to a giant retroperitoneal and mediastinal mass detected in computed tomography (CT) scans. The initial symptoms were transient nausea, diarrhea, and crampy abdominal pain. There was a positive family history including 5 first- and second-degree relatives. Presurgical biopsy revealed a benign ganglioneuroma. Total resection (TR) of a 35 × 25 × 25 cm, 2550-g tumor was obtained successfully via laparotomy combined with thoracotomy and partial incision of the diaphragm. Histopathological analysis confirmed the diagnosis. Surgically challenging aspects were the bilateral tumor invasion from the retroperitoneum into the mediastinum through the aortic hiatus with the need of a bilateral 2-cavity procedure, as well as the tumor-related displacement of the abdominal aorta, the mesenteric vessels, and the inferior vena cava. Due to their anatomic course through the tumor mass, the lumbar aortic vessels needed to be partially resected. Postoperative functioning was excellent without any sign of neurologic deficit. Conclusion Here, we present the largest case of a TR of a GN with retroperitoneal and mediastinal expansion. On review of the literature, this is the largest reported GN resected and was performed safely. Additionally, we present the first systematic literature review for large GN (> 10 cm) as well as for resected tumors growing from the abdominal cavity into the thoracic cavity.

We present a case of a 26-year-old right hand dominant male landscaper with a slow growing right ring finger subungual mass. MRI confirmed a 0.9 × 1.5 × 0.9 cm well circumscribed subungual mass believed to be consistent with a glomus tumor, although size and symptoms were not consistent with that diagnosis. The mass was completely excised and diagnosis of schwannoma was confirmed by H&E histology. A literature search was performed utilizing the term “subungual schwannoma.” Four case reports were found describing this diagnosis in the hand as well as a single case report describing it in the foot. In summary, this is a 26-year-old male who presents with a schwannoma in the unusual subungual location. Although rare, based on our case and the existing literature, subungual schwannomas should be included in the differential diagnosis of a slow growing subungual mass, particularly if symptoms and exam are inconsistent with more common etiologies.

Embryonal Tumor

Embryonal tumor with abundant neuropil and true rosettes (ETANTR) is rarely seen in the brainstem, and there are few case reports of brainstem ETANTR in the literature. Accordingly, the characteristics and the role of surgical treatment of this rare entity remain unclear. The authors present a case of brainstem ETANTR involving a 33-month-old boy along with a review of the literature and discuss the role of surgical removal in the treatment of this entity. In the authors’ case, the tumor was surgically treated with subtotal resection, which resulted in improvement of the patient’s preoperative symptoms. Chemotherapy was initiated but did not appear to be effective, radiotherapy was declined, and the boy died 6 months after the operation. Based on their analysis of 10 previously reported cases and their own case, the authors conclude that, with respect to survival, surgery may be beneficial even in cases of ETANTR in the brainstem. They note, however, that further studies with a large number of cases are needed to validate the role of surgical treatment in brainstem ETANTR.

Adenomyomas are benign tumors composed of smooth muscle and endometrial tissue. These tumors usually arise from the myometrium. Extrauterine adenomyomas are rare with only a few case reports available in the literature. Here, we report an unusual case of multiple adenomyomas in a 39-year-old woman six years after hysterectomy for multiple leiomyomata. To the best of our knowledge, this is the first case of extrauterine adenomyoma presenting as an upper abdominal mass.

Abstract Subependymomas are a rare subtype of ependymomas, slow growing WHO grade I tumors that develop either intracranial from the subependymal glial precursor cells layer of the ventricles or intramedullary. These tumors originate in the undifferentiated Subependymal layer of cells that can become either ependymocytes or astrocytes. Most of the subependymomas are located inside the fourth ventricle (50-60%). We reviewed the case of a 40 years old woman with a giant solid cystic fourth ventricle ependymoma. The patient underwent total resection of the tumor through a subociipital transvermian approach. We discussed the characteristics of these benign tumors and reviewed the literature on this subject and concluded that total resection is the treatment of choice for symptomatic Subependymomas localized in posterior fossa.

Choledochal cysts (CDC) are cystic dilatations of the biliary system, which are usually found in children and uncommon in adults, and type VI choledochal cyst which is isolated cystic dilatation of the cystic duct is a very rare occurrence and only single case reports are documented in the literature. We have reported a case of a young girl who was diagnosed as having Type VI CDC on pre-operative MRCP and found to have the same intraoperatively. She was treated with a simple cholecystectomy with cyst excision.

Endosalpingiosis is a benign and rare entity whose pathophysiology remains unknown. It has been described in pelvic organs, the abdomen, or axillar lymph nodes. Its underrecognition has occasionally led to its misinterpretation for an adenocarcinoma. This case reports the treatment and follow-up of vaginal endosalpingiosis, presenting as a vaginal polyp in a premenopausal women with intermenstrual bleeding. To our knowledge this is the first reported case of vaginal endosalpingiosis and the second mucosal localization after bladder endosalpingiosis.
