Benign tumors of adipose tissue are classified as lipoblastomas , constituted by immature fat cellular telephone ; hibernomas , consisting of mature chocolate-brown fatness cells and lipomas , form by matured white fatness cellular telephone .
Lipomas are the most frequent fatty tissue tumor and likely also the most frequent flaccid tissue paper tumour . They can be observed in any age group , although they are more vulgar in unseasoned adult . They come about more frequently in women because of the slap-up symmetry of consistence adipose tissue paper they gift . These character of benign tumors are diagnose more often in the 5th and 6th 10 of life and are rare in the childhood .
Are Lipomas Genetic?
Its etiology is unknown . Various theories have been purpose without any having been fully accepted : sporadic , transmitted , hormone / metabolic and traumatic . of late , certain genetic mutations have been studied in these tumors , especially at the stage of 12q13 - 15 and 6p13q .
The causal agency of lipomas is unknown . Lipomas are usually hereditary ; therefore , there may be genetic factors involved in their establishment .
They are usually solitary tumors , but there are 3 types of multiple lipomatosis syndrome : Dercum ’s disease ( also known as adiposis dolorosa ) , multiple genetic lipomatosis , and symmetrical benign lipomatosis ( also call Madelung ’s or Buschke ’s disease ) .
Lipomas can be locate anywhere in the body . They are usually located in the subcutaneous plane and are symptomless ( which means they do not generate any symptom ) ; they are rarely locate in deep planes : intramuscular , intermuscular , periosteal or intraosseous , being able to produce compression of the adjacent nerves .
The clinical aspect varies depending on the positioning . In general , they manifest as well - delimited , nomadic peel neoformations with a soft ( rubbery ) and elastic body . Its growth is dumb until it reaches a unchanging size ( on fair , two to 10 centimeter ) and , generally , they do not get symptomatology . Some develop considerably and they are tie in with a big variety of symptoms that can dissemble the patient ’s daily activities .
Its usual topography is the body and the proximal part of the upper limbs . localisation principle in script is uncommon : it represent only the 5 % of benignant tumor .
At the hand level , the most common location is in the antebrachial , thenar and hypothenar region . Those that involve phalanges ( fingers ) are very rare , with an approximative relative incidence of 1 % . The localization in this region have a decrease in the mapping and mobility of the hand and/or articulatio radiocarpea , characterized by an paradigm of “ induction finger ” , alteration in flexion and pair of pincers function .
patient may also attest neurological symptom by condensation in the peripheral nerves of the hand ( alteration in sensitivity , pain , carpal burrow syndrome , etc . ) .
Regarding the diagnosing of this pathology , the clinical chronicle , and physical examination are sufficient in most display case . In deep lipoma the documentation of imaging tests is necessary ; mere skiagraphy bring out a radiolucent masses , sonography help to notice and name space - occupying lesions and differentiate a solid mass from a cystic and the MRI ( magnetic resonance imaging ) , asunder from the diagnostic orientation course , locate exactly the tumor and indicates its human relationship with adjacent structures , such as nerves , while also helping the doctors with surgical planning .
The histologic subject area shows that these lesions are constituted by adipose tissue paper that resembles normal .
When it is completely take out , one can mention a abridgement beleaguer the aggregate of adipocytes . A group of lipomas is the so - called hibernomas , be by lipoblasts . Depending on the associated part , we can utter of angiolipoma , fibrolipoma , angiofibrolipoma or polymorphic lipoma . The differential diagnoses admit hibernomas , lipoblastomas , angiolipomas , and neurofibromas .
The treatment of choice is surgical resection . The indications for performing this procedure are the presence of pain and concretion of neurocutaneous social organization , which occurs more frequently when located in narrow space such as the helping hand . The result after operating theater is generally good ; however , because extensive dissection must be perform , with the mobilisation of neurovascular bundle , loss of part or sensitiveness may occur .
Conclusion
A lipoma is not cancer and is commonly inoffensive . seldom , a lipoma becomes a serious condition . However , if you note a lump or well anywhere on the body , have it checked by a doctor .
