Endoscopic Diagnosis of Intestinal Lipomas

Abstract:A retrospective endoscopic study of 11 patients with intestinal lipomas was conducted. The patients included 2 with duodenal—, 2 with small intestinal—, and 7 with large intestinal lipomas. Endoscopically, in addition to features common to all submucosal tumors, lipomas often present characteristic findings including a yellowish surface color and softness of the tumor. The yellowish color was noticed in the 6 patients whose tumors were 10 mm and more in size. In the 2 patients with lipomas in the small intestine, the yellowish color was diminished by hemorrhages, inflammation and fibromusculosis in the lamina propria mucosa due to mechanical irritations such as peristalsis and intussusception. Thus, the appearance of the yellow color was related to the size of the tumors and the histological changes in the overlying mucosa. Endoscopic palpation with biopsy forceps aids in making a diagnosis of lipomas; and the cushion sign was noticed in 3 of 4 patients who underwent the palpation. The naked fat sign is pathognornonic but was observed in only 1 patient with a duodenal lipoma, in which the fat tissue was exposed by denuding the mucosa with the biopsy forceps. Scopic biopsies revealed lipomas in 3 patients. Careful observation of the color and palpation during the endoscopic examination are important for making a correct diagnosis and avoiding the unnecessary resection of lesions.

Laparoscopic removal of a large colonic lipoma

A 72-year-old white male was found to have a 6-cm submucosal mass at 35 cm on screening sigmoidoscopy. The lesion had all the characteristics of a submucosal lipoma. Instead of performing a laparotomy with its potential morbidity, the lesion was removed laparoscopically in its entirety without untoward operative sequelae. Laparoscopic techniques have had a profound impact on the treatment of patients with surgical disorders. This new technology can be applied to selected patients with colorectal diseases.

The Treatment of Atypical Lipoma with Liposuction

Large lipomas may best be treated with liposuction. Once a lipoma enlarges to 4 cm or more, liposuction has several advantages over conventional surgery. A well-demarcated lipoma 15 cm in diameter and deep to muscle was treated by liposuction. Biopsy showed an atypical lipoma. Because the entire tumor was removed by liposuction, we feel that the prognosis is excellent. The cosmesis and morbidity results were far superior to those anticipated with conventional excisional surgery. Small superficial lipomas may be treated by suction lipectomy and the surrounding area can be contoured symmetrically at the same time, whereas large ones can be liposuctioned completely without extensive surgical extirpation and morbidity. Because such big lesions may represent atypical lipomas or liposarcomas, care must be taken to remove the entire tumor.

Hypopharyngeal Lipoma as a Cause for Sudden Asphyxial Death

Lipomas of the hypopharynx are uncommon tumors that are rarely life threatening. When positioned in the hypopharynx, asphyxia may be the result of the tumor size or sudden displacement into the oropharynx. We present a case of a large hypopharyngeal lipoma, review the literature, and discuss mechanisms by which these lesions may cause sudden asphyxial death.

Abdominal wall lipoma—CT and MRI appearance

Although soft tissue lipomata are common tumours, a large lipoma arising from the deep layers of the abdominal wall would appear to be excessively rare and the site of origin may be difficult to determine. The CT and MRI appearances of such a tumour are described.

Aneurysmal jugular vein and a large myxoid lipoma: unusual etiology for an enlarging cervical mass in a child

Internal jugular venous aneurysms are extremely rare in the pediatric population. The evaluation and surgical treatment of a myxoid lipoma and a jugular venous aneurysm presenting as an enlarging cervical mass in a child is described. Although neck masses commonly present in childhood, accurate diagnosis of unusual or atypical lesions can now be readily established by noninvasive imaging techniques. Surgical excision of jugular venous aneurysms is safe and effective. Only a few patients require operation and treatment options should be individualized.

Endoscopic correction of intussusception and removal of a colonic lipoma

Colonic lipomas are rare, but are the most common benign tumors except for adenomatous polyps.l Lipomas usually arise from the submucosa and range in size from a few millimeters to several centimeters. There is a similarity between the clinical presentation of some lipomas and other tumors. If the lesion can be confirmed to be benign and if the diameter of the base of the tumor is less than that of the lesion, endoscopic polypectomy can be an effective management. We report endoscopic polypectomy of a large lipoma in the colon following endoscopic correction of an intussusception.

Case report of a boy with penoscrotal transposition, double urethra, pseudodiphallia, and ectopic scrotum

The paper describes a 14 year old Saudi boy with penoscrotal transposition and double urethra placed side by side in the penis. Ectopic scrotal skin and a pseudopenis were seen over the right ischial tuberosity. The patient had a large lumbosacral lipoma, which probably caused paralysis and atrophy of the right leg through an intraspinal extension.

A large epicardial lipoma — an insight into the surgical anatomy of the interatrial septum

A large epicardial lipoma was successfully resected. Consideration of the origin of this tumour gives an insight into the surgical anatomy of the interatrial septum.

Large intramuscular spindle‐cell lipoma

A case of a large spindle-cell lipoma in an intramuscular (subfascial) localization is reported. The tumour occurred in a 58-year-old male patient and was localized subfascially in his left deltoid muscle. The tumour measured 20 X 8 X 8 cm; its weight was 780 grams. After initial biopsy, the tumour was extirpated. Microscopically, the tumour tissue consisted of mature fat cells and spindle-cell areas in varying amounts, constituting a typical appearance of a spindle-cell lipoma. There were no histological signs of malignancy. Especially, no areas of liposarcoma differentiation were detected. The patient is well, with no signs of recurrence, one and a half years after the operation. We have reviewed the literature on spindle-cell lipoma, and we believe this is the first example of this neoplasm to be reported in an intramuscular (subfascial) localization.

Computed tomographic myelography in the investigation of childhood scoliosis and spinal dysraphism

The combined investigations of positive contrast myelography and computed tomographic (CT) myelography were performed on 53 consecutive children. Thirty-eight (72%) of these investigations were performed as a routine pre-operative procedure to identify occult spinal dysraphism in patients with childhood scoliosis; the remainder were because of the "orthopaedic syndrome", cervical radiculopathy, back pain and patients with clinical findings to suggest spinal dysraphism. In the 20 patients (38%) with idiopathic scoliosis, there was no case of spinal dysraphism and CT myelography provided no additional information to the myelogram. In the seven patients with spinal dysraphism the plain radiographic abnormalities identified were lumbar vertebral abnormalities (five), thoracic vertebral abnormalities (one), and sacral agenesis (one). Diastematomyelia was found in four patients, a low tethered cord and lipoma in two patients and a large lipoma in one patient. In all of these cases the myelogram indicated the intraspinal abnormalities; however, CT myelography provided more precise anatomical detail. We conclude that CT myelography is not indicated in the initial preoperative assessment of idiopathic scoliosis but should be reserved for patients with congenital or complicated scoliosis where the association with dysraphism is well recognised.

頚部に発生した脂肪腫の１例と臨床統計的観察

A case of relatively large lipoma of the right neck is reported and thirty-three cases of lipomas treated in our department from 1965 to 1986 are reviewed.A 64-year-old man was admitted to our department complaining of a right neck swelling. The preoperative diagnosis was lipoma based on clinical findings as well as the image findings of CT scan and echogram. The tumor was excised through a cervical skin incision under general anesthesia. It lied between the platysma and the superficial layer of the cervical facia. The enucleated yellow and soft specimen was 12×7×6.5cm in size, and covered with a thin fibrous capsule. The histopathological diagnosis was lipoma. The prognosis has been good for about one year. From our statistical study the distribution by site of 33 lipomas is as follows: eleven cases in the check, five in the lower lip, five in the tongue, three in the submandibular region, two in the gingiva, the floor of the mouth, the soft palate, the preauricular portion each other and one in the neck.Males are more affected than females.76% of the patients are over 40 years of age.

Computed tomography of lipoma of corpus callosum and choroid plexus lipoma: Report of two cases

Lipoma of corpus callosum and choroid plexus lipoma are rare developmental anomalies arising as a result of maldifferentiation of primitive meningeal tissue. Two cases are reported along with a brief review of literature. The first case presented with chronic, headache, and a large lipoma of corpus callosum associated with choroid plexus lipoma was discovered. The second case had no symptoms before the discovery of corpus callosal lipoma on computed tomography, which was done for a head injury. None of the lipomas showed any calcification.

Intrathoracic Lipomas in Children

An asymptomatic 8-year-old boy had had a large intrathoracic tumor for five years. When noninvasive technics proved fruitless in establishing a diagnosis, surgical removal was elected. A large posterior mediastinal lipoma was discovered. This is the 15th intrathoracic lipoma reported in the pediatric age group.

Chondroma of the Spine in a Newborn Infant

We report a newborn infant with a chondroma of the spine covered by a large lipoma. The child had no neurological deficit. Presenting as a tumor of the back, the chondroma was successfully excised. A review of the pertinent literature emphasizes the rarity of this lesion.

THE TRAUMATIC PSEUDOLIPOMA

A contour deformity, clinically reminiscent of a large lipoma, can develop after a severe shearing-type injury to the upper thigh, hip, or sacrum, particularly in young women. As the injury is rarely dealt with in the first weeks, it usually presents after a deep scar has contracted. At this stage active surgical intervention seriously increases the aesthetic problem. Conservative treatment with massage, pressure, and possibly injection of steroids is more effective. To the best of our knowledge, this condition has not previously been described.

舌下部に発現した巨大な脂肪腫の一例

A lipoma is a soft tissue tumor consist of adipose tissue. However, although lipoma of the oral cavity are uncommon, the frequent location of the tumor are the cheek, the tongue, the lip and the floor of the mouth. A case of large sublingual lipoma clinically suggestive of epidermoid cyst has been reported. The histo-pathologic feature seen in this tumor was lipoma.

Lipoma of the colon: report of three cases.

Summary Three cases of lipoma of the colon and rectum are reported. In the patient with a rectal lesion, prolapse of the rectal mucosa was the presenting symptom; the second patient had a lipoma of the sigmoid colon, and the third had a large lipoma of the transverse colon with intussusception and almost complete bowel obstruction. Excision of the lipoma was done in two cases; partial colectomy with end-to-end anastomosis was performed in the third. All the patients made good recoveries and became free of symptoms. The literature on the subject is reviewed.
