The adipose tumor is a mesenchymal tumor that occupies the first place in frequency among soft tissue tumors , which varies between 16 to 50 % . It represents , in turn , 1 % of benign tumors . It normally appears after 20 geezerhood of old age , being a very rare finding in children . Its keen intro in the female sex is cite , which many attribute to the interview for esthetic reason .
What is Sacral Lipoma?
The sacrococcygeal region end the ulterior wall of the small pelvis and is the site of insertion of muscle and ligament . It is deserving bring up that sacral lipomas are not very vernacular . They must be certified as a marker of dysraphism that means that its mien require discarding an rudimentary bone and/or neurological abnormality .
The sacral lipoma is symptomless masses , proportionate , slow - rise , of regular shape and attack to ovoid or discoid , pasty or cystic consistency , usually lobed open . They have good mobility and can lead to the organisation of dimples on the aerofoil when exercising their inactive movement . The consistency may increase after the applications programme of deoxyephedrine , a maneuver used on certain occasions to prefer its diagnosing . The palpation is painless and when there is a intuitive feeling of discomfort , it is due to densification of peripheral nerve or special smorgasbord of the same tumour .
It has also been necessitate it ’s most common presence in weighty soul , although important free weight departure does not reduce the size of it of sacral lipomas . They rise slow or are stationed , but any sudden variation in it must alert physician to its malignant translation , an case that is considered very rarified . Likewise , its self-generated regression is extremely infrequent .
By its location , there are distinguished two character of solitary lipoma :
Between 6 and 7 % of patients with sacral adipose tumor have multiple lesion . In the macroscopic subject field of a operative piece , expert see that it presents a thin pale - lily-livered capsule , as well as the lipomatous part cut .
The histological bailiwick shows a capped organization , well delimited and form by lobes of ripe adipocytes , between which there are vascular connective septum of trivial heaviness . Sometimes the fat person element face a clear intranuclear blank space that not only lack pathologic meaning but its existence has been report in normal fatty tissue . The size of lipocytes is usually equal to or slightly greater than normal adipocytes . The vascular connection is important but its visual image is scarce , given the densification performed by the same cellular components .
Its chemical examination reveals the quantitative divergence in relation to vulgar roly-poly tissue paper .
The “ monotony ” of its semiological elements is contrast with a multiplicity of human body of presentation and histological variation .
Syndromes of multiple lipomas : Multiple subcutaneous lipomas , identical from unfrequented , but with special clinical interests :
a ) Multiple Familial Lipomatosis : It appears between 30 to 60 years , it has an initial stage with moderate pain , which after one to two years go away as its growth stabilizes , gain values close to 5 centimeter in diam per tumor .
b ) Multiple Symmetric Lipomatosis : It predominates in a proportion of 4 : 1 and up to 15 : 1 in the manlike sex . Fat deposits have been classified into two types : circumscribe , in the mannikin of a “ buck neckband ” set up in the neck and shoulder girdle ( strikingly there is also reduction of uncommitted adipose tissue paper ) and diffuse , honor distal extremity , of value to differentiate it ofobesity .
