Adult intussusception is rare, and the majority of cases has an underlying cause that requires surgical resection. We report a case of a 39 yr-old man with ileo-ileo-colic intussusception caused by ileal lipoma that was successfully managed by a laparoscopic-assisted surgical maneuver. Using a three-cannula technique, ileo-colic intussusception was reduced laparoscopically. Then, through a 4-cm transverse incision in the right lower quadrant abdomen, ileo-ileal intussusception was reduced manually, and a resection of the tumor-bearing ileal segment and end-to-end anastomosis was performed extracorporeally. Although the role of laparoscopy in managing intussusception is not clearly defined, laparoscopy may be an alternative approach to the surgical treatment of adult intussusception in selected cases.

One type of soft tissue lesions of the oral cavity is lipoma, which is a kind of benign tumor composed of mature lipid cells. Although the lipoma presents as one of the most common mesenchymal neoplasms, most tend to develop on the trunk and proximal portions of the extremities. However, lipomas in the oral and maxillofacial region are much less frequent. Here we present a case of an intraoral lipoma in a six year-old child.

A 12-year-old boy was admitted for complaint of progressive urination disorder for over 2 years. Physical examination found dysesthesia in the perineal region and disappearance of anal reflex with anal relaxation and a spinal cleft in the sacrococcygeal region. Lumbosacral magnetic resonance imaging MRI showed a low-set of the spinal cord, tethered cord, spina bifida of sacral vertebrae, and meningocele combined with lipoma inside and outside of the spinal canal. Ultrasonography displayed a significantly increased residual urine volume. The diagnosis of tethered-cord syndrome resulting from mixed lipoma was thus established. During the microsurgery, the adhesions between the spinal cord, coccygeal nerve and lipoma were released with a laser scalpel, and the lipoma inside and outside of the spinal canal was excised, after which the dural defect was repaired. The patient recovered smoothly, and the urinary function was normal at the follow-up 6 months after the surgery. Spinal cord lipoma can be classified into 2 types based on the integrity of the dura mater, and in this case, a combined dural defect was found. A definite diagnosis can be derived from the clinical manifestations and MRI findings. Microsurgery remains the currently only effective treatment, and a favorable prognosis can be expected after an early surgical intervention, especially before the functional lesion of the spinal cord. The integrity of the local dura mater considerably affects the outcome of the treatment, and dural defect often leads to surgical difficulty and poor results. The key to a successful operation lies in a full release of the adhesion and avoidance of injury to the conus medullaris and cauda equina. A reoperation in case of recurrence should be carefully evaluated for its benefits.

OBJECTIVETo study the nature of the residue hard tissue after liposuction in lipoma and its role in lipoma recurrence.

METHODSThe residue hard tissue after liposuction was collected for histologic study, including HE-staining and immunohistochemistry with antibody of stem cell marker (CD29 and CD44). The average density and area of positive cells were analyzed statistically.

RESULTSThe residue hard tissue had a medium hardness. The center tissue was light yellow surrounding by soft, loose, irregular and cord-like tissue. The normal fat tissue is light yellow with a soft and unanimous texture. HE-staining showed abundant stromas in residue hard tissue, with lots of fibroblast-like cells locating among adipocytes. The cytoplasm was less with large and blue-staining nucleus. In normal fat tissue, the fat cells were uniform which were round or polygon. The stromas was less and the fibroblast-like cells were comparatively less. The slices were stained with antibody (CD29, CD44) of stem cell marker. The density and area of positive cells were much more in residue hard tissue than those in normal adipose tissue. Two Independence Samples T test were as follows: (t'CD29 = 9.931, P = 0.000; (t'CD44 =10.171, P = 0.000 for density; and (t'CD29 = 7.761, P = 0.000; tt'CDRR = 6.639, P = 0.000 for area. The difference was significant.

CONCLUSIONSAbundant fibroblast-like cells that are signed by the marker of stem cells exist in residue hard tissue. Those cells are proven to be lipoma derived stem cells (LDSCs) which may play an role in lipoma recurrence after lipoma liposuction.

We reported a case of children's OSAHS caused by the huge fibrolipoma in pharynx nasalis. The patient was a 10-years-old child who went to the hospital with the chief complaint of "Snoring and mouth breathing during sleep for 10 years". Imaging tests found one huge tumor in pharynx nasalis before the operation. The tumor was resected totally. The postoperative pathological diagnosis was fibrolipoma. No recurrence was noted during the follow-up visit one year postoperatively. The clinical features, diagnosis, treatment, pathology and prognosis were reviewed herein.
