Congenital hairy polyp associated with cleft palate-a rare entity

Hairy polyps are common congenital benign lesions of oroand nasopharynx containing elements of both ectodermal and mesodermal origin. However, their occurrence in palate is quite rare. Here we present a case of hairy polyp associated with palatal cleft in an eight months old female infant. We discuss the clinicopathological features, etiology, proposed theories related to its formation and its significance.

Compounds used for 'injection lipolysis' destroy adipocytes and other cells found in adipose tissue

BACKGROUND

A widely applied technique to reduce subcutaneous fat pad size involves subcutaneous injection of a phosphatidylcholine preparation ('injection lipolysis'). As the mode of action is mostly unknown, we planned to study cellular effects of the particular drug used in Germany (Lipostabil(R)).

METHODS

Human preadipocytes, adipocytes, vascular and skeletal muscle cells as well as renal epithelial cells were incubated in the compound, morphological changes were described, and cell vitality was measured.

RESULTS

A strong cytolytic effect of the compound was signified by lipid release and acridine orange staining of dying adipocyte nuclei. When the undiluted compound was used, more than 90% of cell death occurred after 90 s in preadipocytes, after 6 min in vascular smooth muscle cells, skeletal myotubes and renal epithelial cells, and after 15 min in adipocytes. Dilution slowed down cytolysis, but still >50% of the cells disappeared during 30 min incubation. Neither osmotic effects nor differences in medium acidity were responsible for cell death.

CONCLUSION

Injection lipolysis with phosphatidylcholine as the major injected compound reduces subcutaneous fat pad size through cell and tissue destruction. Beside the lack of a clear risk-benefit analysis, applying this technique represents off-label drug use and application of a drug by a contraindicated route.

Hemosiderotic fibrohistiocytic lipomatous lesion: case report and review of the literature

CONTEXT

Lesions of the adipose tissue are the most common type of soft-tissue lesion among adults.

CASE REPORT

We describe the case of a 33-year-old female patient with a soft-tissue lesion in her left knee that was diagnosed as a hemosiderotic fibrohistiocytic lipomatous lesion. This type of lesion, which was described for the first time in 2000, preferentially affects the ankle region of middle-aged women with a history of previous local trauma. Lesion recurrence is common, caused by incomplete resection, although there have not yet been any reports of metastases. After a review of the literature, we describe the clinical, radiological, morphological and immunohistochemical characteristics, along with their main differential diagnoses.

Ileocecal valve lipoma with refractory hemorrhage

BACKGROUND

Lipomas are the most common benign mesenchymal tumors of the gastrointestinal tract, with the colon being the most prevalent site. Intestinal lipomas are usually asymptomatic. Tumors >2 cm in diameter may occasionally cause nonspecific symptoms, including change in bowel habits, abdominal pain, or rectal bleeding, but with resection the prognosis is excellent. Herein, we describe the case of an elderly male who presented with painless hematochezia.

METHODS

Both colonoscopy and computed tomography of the abdomen and pelvis confirmed the presence of a mass near the ileocecal valve. Because of continuing bleeding, the patient required laparoscopic-assisted right hemicolectomy to resect the mass.

RESULTS

Both gross and microscopic pathology were consistent with lipoma at the ileocecal valve.

CONCLUSION

Previous cases of ileocecal valve lipomas have been reported in the English literature, with the majority presenting as intussusception or volvulus. We present a rare case of an ulcerated ileocecal valve lipoma presenting as lower gastrointestinal bleeding that was treated successfully with laparoscopic resection.

Jejunal lipoma with intermittent intussusception revealed by partial obstructive syndrome

Jejunojejunal intussusceptions are not very common in adults, and unlike in children, a lead point is usually found. The clinical presentations in adults tend to be more chronic or intermittent, and they include obstructive syndrome, abdominal cramps, gastrointestinal bleeding, or palpable abdominal mass at physical examination. These unspecific symptoms often lead to late diagnosis after many investigations or even only after an inappropriately extensive surgery. We report the rare case of a 37-year-old female with intermittent bowel obstruction due to jejunojejunal intussusception secondary to the lipoma. The main clinical signs of this uncommon pathology are presented together with the necessary paraclinical investigations that enable surgical treatment.

Large vulvar lipoma in an adolescent: a case report

Lipomas are the most common benign tumors of soft tissues. However, conventional lipomas have been reported only rarely as presenting in the vulva. We present a case of vulvar lipoma in a 17-yr-old woman, possibly caused by chronic intermittent irritation.

Endoscopic resection of forehead lipoma: A subperiosteal single-portal approach

Forehead lumps which are commonly excised for cosmetic reasons, are done through a traditional open excision technique. In the Asian population, open excision commonly results in a pigmented scar which tends not to fade with time and this can be a concern to some patients. The aims of this paper are to describe an endoscopically assisted technique of surgery, with emphasis on the subperiosteal, single-portal approach; to review the outcome of the surgery, and to define the indications for its use.

Post-traumatic lipoma of the parotid gland: case report

The incidence of lipoma among parotid tumours ranges from 0.6% to 4.4%, with most series reporting an incidence of 1%. The most common origin of these tumours, in the parotid gland, is from the superficial lobe and, only rarely, from the deep lobe. Lipomas, upon clinical history, are found to be most frequently related to an episode of trauma. Computed Tomography scan and Magnetic Resonance Imaging can lead to a pre-operative diagnosis of lipoma. The case is described of lipoma of the superficial lobe of the parotid gland.

Tethered spinal cord with double spinal lipomas

Although lumbosacral lipoma is reported to occur in 4-8 of 100,000 patients, and 66% of lipomyelomeningoceles in young patients are accompanied by hypertrophic filum terminale, it is very rare to find two isolated spinal lipomas simultaneously. A 3 month-old baby girl was admitted to the hospital for a protruding, non-tender, soft, subcutaneous 2.5 cm mass of the lumbosacral area that had been present since birth. Simple radiography showed a spinal posterior arch defect from L3 to L5, and magnetic resonance imaging (MRI) demonstrated two isolated spinal lipomas, a transitional type from L3 to L5, and a terminal type below S1 without dural defect. The cornus medullaris was severely tethered descending to the S1, but there was no cerebellar or brain stem herniation on the MRI. We suggest that the presence of a combined spinal lipoma should be a point for careful differentiation in an infant with spinal lipoma.

Laparoscopic management of colonic lipomas: a case report and review of the literature

Colonic lipomas are infrequent lesions, yet they are the second most common benign lesions of the colon after benign adenomatous polyps. Their treatment ranges from observation to segmental colectomy and has been a matter of debate since Bauer first reported them in 1757. With the advent of new technologies, therapeutic options now include observation, endoscopic removal, laparoscopic removal, and traditional open surgery. We present a case of colonic lipoma presenting with indeterminate symptomatology, its workup, treatment outcome, and a review of the current literature.

Parapharyngeal space lipoma

I ipomas of the Para-pharyngeal space are rare lesions Very few cases of such tumors have be en reported in the literature Definitive diagnosis and decision regarding the surgical approach Here difficult in the pre CT scan era This was further compounded by the complex anatomy of the Para pharyngeal space A case of Para pharyngeal lipoma is being presented because of its ratity and characteristic radiological features After confirmation of the diagnosis the tumor was excised via a transcertical approach.

The expression of MDM2/CDK4 gene product in the differential diagnosis of well differentiated liposarcoma and large deep-seated lipoma

Ordinary lipomas are cytogenetically characterized by a variety of balanced rearrangements involving chromosome segment 12q13-15, whereas well differentiated liposarcomas (WDL) show supernumerary ring and giant marker chromosomes, known to contain amplified 12q sequences. The tight correlation between the presence of ring chromosomes and both amplification and overexpression of MDM2 and CDK4 genes suggests the exploration of the possibility that immunocytochemistry (ICC) might assist in the differential diagnosis of lipoma-like well differentiated liposarcomas (LL-WDL) and large deep-seated lipomas (LDSL). For this purpose, 21 cases of the former and 19 cases of the latter tumours were analysed by ICC and, according to the availability of material, by molecular and cytogenetic approaches. All lipomas displayed a null MDM2/CDK4 phenotype, whereas all LL-WDL showed MDM2/CDK4 or CDK4 phenotypes. Southern blot analysis performed on 16 suitable cases, complemented by fluorescence in situ hybridization and classical cytogenetic analysis in 11 cases, was consistent with, and further supported the immunophenotyping data. In conclusion, MDM2/CDK4 product-based immunophenotyping appears to represent a valuable method for the categorization of arguable LDSL.

Expression of sialylparagloboside in a case of liposarcoma: aberrant glycosylation in tumors arising in adipose tissues

Gangliosides of liposarcoma, lipoma and lipids from omental tissues were analyzed. By immunostaining after thin layer chromatography, gangliosides of liposarcoma were identified as GM3, sialylparagloboside and GD3, whereas those of lipoma were GM3 and GD3, and those of fat in omental tissues were GM3, GD1a, GD3 and some unknown ones. Expression of sialylparagloboside is thought to be very rare.
