Angiolipoma in the region of the hypopharynx-esophageal introitus is a rare occurrence. Surgical treatment was performed in the few cases reported in the literature. Endoscopic submucosal dissection (ESD) is a minimally invasive treatment for hypopharyngeal and esophageal lesions. Our objective was to evaluate the feasibility, safety, and efficacy of ESD for treatment of angiolipoma at the hypopharynx-esophageal introitus. The patients with submucosal tumors at the hypopharynx-esophageal introitus were diagnosed as angiolipoma by preoperative evaluation with endoscopy, endoscopic ultrasonography, and computed tomography (CT). The patients who were diagnosed with angiolipoma agreed to undergo endoscopic submucosal dissection. Under general anesthesia and endotracheal intubation, ESD was used to remove the lesions. Preoperative, intraoperative, and postoperative data were collected and analyzed to evaluate the feasibility, safety, and effectiveness of endoscopic submucosal dissection. From January 2013 to December 2018, 6 cases of angiolipoma were treated with ESD with a success rate of 100%. The average operation time was 107.0 ± 69.4 minutes. Intraoperative blood loss is the main risk. Endoscopic thermocoagulation successfully stopped bleeding in all cases. Pharyngeal pain and painful swallowing were the main clinical signs. There was no stricture at the hypopharynx-esophageal introitus after the operation. ESD treatment of angiolipoma at hypopharynx-esophageal introitus is feasible, safe, and effective.

BACKGROUND
Angiolipomas are benign mesenchymal tumors that infrequently affect the head-and-neck region and can appear with infiltrating and non-infiltrating forms. Surgical excision is the treatment of choice; however, there are other alternatives to manage this condition whose consideration is quite useful to evaluate per each particular case.
CASE DESCRIPTION
An 11-year-old girl was diagnosed with non-infiltrating angiolipoma in the subtemporal region, the zygomatic, and pterygomaxillary fossa; she had a history of having undergone surgery on two previous occasions with a failed resection attempt due to the high vascularization of the injury and significant transoperative bleeding. The condition was managed with minimally invasive techniques through microwave ablation, requiring two sessions, achieving very satisfactory results both esthetically and in the final size of the lesion.
CONCLUSION
The microwave ablation technique may turn out to be a very useful tool for the management of lesions with high vascularization such as angiolipoma. This technique offers a new possibility for initial management, both independent of and complementary to other management techniques for other lesions at the base of the skull and/or facial massif regions.

BACKGROUND
Albeit rarely, different spinal pathologies may require surgical treatment during pregnancy. The management of such cases poses a series of challenges, starting with adequate body positioning.
OBJECTIVE
To illustrate limits and indications of the different surgical positioning strategies for pregnant women undergoing spine surgery.
METHODS
We performed a systematic review of literature about the described surgical positioning strategies used for spinal surgery during pregnancy, discussing advantages, indications, and limits. We also describe of a novel three-quarters prone positioning for dorsal pathology.
RESULTS
The surgical strategy may vary according to several factors, such as the location and the nature of the underlying pathology, the stage of the pregnancy, and the clinical condition of mother and fetus. During the second trimester, the habitus begins to raise issues about both the abdominal and the aortocaval compressions. The third trimester implies neonatal and ethical challenges: both fetal monitoring and the possibility of urgently proceeding to delivery should be guaranteed. The prone position is feasible during the second trimester provided an adequate frame is supplied. The lateral or three-quarters prone positioning may offer the safest option in the last stages of pregnancy, whereas both supine and sitting positionings are anecdotal.
CONCLUSIONS
Gestational age, surgical comfort and maternofetal safety should be balanced by a multidisciplinary team to tailor an adequate positioning plan for each individual case. The early third trimester is the more limiting period because of the womb hindrance favoring lateral or three-quarters positionings.

Angiolipomas are slow-growing, soft tissue tumors consisting of mature adipocytes and thin-walled blood vessels. While most angiolipomas are subcutaneous lesions in the trunk and upper extremities, intraosseous angiolipomas are rare at cranial site. We present the case of a 61-year-old female with an enlarging lesion in the left frontoparietal skull following minor head trauma. Radiography confirmed an expansile, enhancing, spiculated bony lesion in the left frontoparietal calvarium with extension outside the cortex into the soft tissues. She underwent a craniectomy for complete resection of the calvarial mass, which was histologically composed of mature adipocytes and disorganized blood vessels highlighted by an immunophenotype positive for S100 and CD34, respectively, consistent with a cranial intraosseous angiolipoma. The review of the literature that reported five cases of cranial intraosseous angiolipoma with our case representing the sixth case is discussed.

Review
Spinal angiolipomas are benign uncommon neoplasm composed of mature lipocytes admixed with abnormal blood vessels. They account for only 0.04-1.2% of all spinal tumors. We report two cases of lumbar extradural angiolipoma and review previously reported cases. We found 118 cases of spinal epidural angiolipoma (70 females and 48 males; age range 1.5-85 years, mean 44.03) spanning from 1890 to 2006. Prior to diagnosis 40.6% of the patients had weakness of the lower limbs. The interval between the initial symptoms and tumor diagnosis ranged from 1 day to 17 years (mean 20.2 months). Except for four cases diagnosed at autopsy, 109 patients underwent surgery and gross-total resection was performed in 79 cases (72.4%). Spinal angiolipomas are tumors containing angiomatous and lipomatous tissue, predominantly located in the mid-thoracic region. All angiolipomas show iso- or hyperintensity on T1-weighted images and hyperintensity on T2-weighted images and most lesions enhance with gadolinium administration. The treatment for spinal extradural angiolipomas is total surgical resection and no adjuvant therapy should be administered.

BACKGROUND/AIM
Angiolipoma is a rare benign soft tissue tumor composed of mature adipocytes and blood vessels. Genetic information on angiolipomas is scarce. With the single exception of one tumor which carried a t(X;2)(p22;p12), all angiolipomas hitherto investigated cytogenetically had normal karyotypes.
MATERIALS AND METHODS
G-banding chromosome analysis was performed on three short-term cultured angiolipomas. Fluorescence in situ hybridization (FISH) analysis using a commercially available RB1 deletion probe was also done.
RESULTS
All three angiolipomas had abnormal karyotypes with loss or structural rearrangement of chromosome 13. The first tumor had the karyotype 46,XY,-6,del(13)(q14),+mar[cp5], the second had 44~45,XY,t(1;10;15)(p21~22;q24;q24),-13[cp5], and the third karyotype was 43,XX,t(13;22;17) (q12;q13; q22~23)[14]. FISH analysis showed heterozygous and homozygous deletion of the RB1 probe in case 2 and 3, respectively. FISH analysis failed in case 1.
CONCLUSION
Chromosome 13 was consistently involved in all three angiolipomas.

Angiolipoma has been reported in many cases, which often occurring subcutaneously in the trunk and limbs. However, angiolipoma rarely occurs in the scrotum. In order to better understand its biological characteristics, clinical features and prognosis, in this case, a 41-year-old male with painful angiolipoma in the scrotum was reported.

Epidural angiolipoma is a rare benign tumor consisting of mature adipocytes, blood sinuses, capillaries, and small blood vessels. It constitutes about 0.04%-1.2% of spinal axis tumors and about 2%-3% of extradural spinal tumors. We report a case of thoracic epidural angiolipoma and review the literature. We describe a 42-year-old woman who had weakness and numbness in her lower extremities prior to diagnosis and had an onset of approximately 10 months. The patient was misdiagnosed as schwannoma on preoperative imaging, possibly because neurogenous tumor is the most common intramedullary subdural tumor, and the lesion grew into bilateral intervertebral foramina. However, the lesion demonstrated high signal on the T2-weighted and T2 fat suppression sequences, and the linear low signal at the lesion edge was ignored, leading to misdiagnosis. The patient underwent posterior thoracic 4-6 laminectomy, pathectomy, and spinal decompression/vertebroplasty under general anesthesia. The final pathologic diagnosis was intradural epidural angiolipoma of the thoracic vertebra. Spinal epidural angiolipoma is a rare benign tumor that occurs frequently in middle-aged women and is mostly located on the dorsal side of the thoracic spinal canal. Magnetic resonance imaging findings of spinal epidural angiolipoma depend on the ratio of fat to blood vessels. Most angiolipomas show equal or high signal on T1-weighted images and high intensity on T2-weighted images, with significant enhancement after injection of gadolinium. The treatment of spinal epidural angiolipoma is complete surgical resection with good prognosis.
