Lipoma-case report
A 59-year-old woman was admitted with a 10 years' history of a painless swelling at the right thigh. The lesion became ulcerative over the past few months with mild pain.
She had no significant medical and surgical history.
Examination revealed normal vital signs, chest, heart, abdominal and rectal examinations.
![Page 14: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/14.jpg)
LipomaOn local examination, a large mass
occupying the posterior aspect of the lower two thirds of the right thigh was confirmed.
There was an ulcerative lesion at the posteromedial aspect of the mass.
The right popliteal artery was difficult to palpate, but the posterior tibial and dorsalis pedis were normal.
There was no neuronal abnormality.
![Page 15: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/15.jpg)
Lipoma- case reportBlood tests showed normal blood count, liver
function, urea and electrolytes as well as ESR. She had a normal chest and abdominal X-ray.
The X-ray of the right thigh showed a soft tissue shadow and normal bone.
Surgical excision was performed and the findings were consistent with a giant lipoma.
The wound was closed easily as there was redundant skin because of the size of the mass.
The weight of the specimen was 3.2kg.

Lipoma- case report
The patient had an uneventful recovery and was discharged home with a very good condition.
Histology of the specimen reported benign lipoma.

LipomaThis is the external
surface of a lipoma, a benign tumor of adipocyte origin. •The bright yellow color is typical of fat. •Note the lobulated appearance. This is also typical of this lesion. •This particular tumor arose in the subcutaneous fat (note the small strip of skin denoted by the black arrows).

Case Report-lipoma
A 60 year old male presented in out patient clinic with history of progressively increasing swelling in right thigh, which he noticed 3½ years back. Swelling was otherwise asymptomatic except that he had to wear loose fitting trousers.
On examination, right thigh girth was grossly increased as compared to the left thigh.
![Page 22: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/22.jpg)
Lipoma
There were erythema ab agni over the medial aspect of both thighs (as is usual in Kashmiri people because of Kangri – “the fire pot”).
The swelling was firm, non-tender and free from underlying structures.

CT scan of the right thigh was done which revealed a hypodense mass in the posterior compartment of the thigh beneath the hamstring muscles
![Page 25: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/25.jpg)
Lipoma- case reportFNAC of the swelling revealed mature fat cells, suggestive
of lipoma.
The patient was operated on under general anaesthesia, in prone position and the tumour was found beneath the hamstring muscles and was dissected out easily because of the pseudocapsule.
Wound was closed in layers, leaving a suction drain inside the cavity. Healing progressed uneventfully.
Histopathological examination revealed features consistent with lipoma. The tumour removed measured 21x17x14cm in size and weighed 2,95 Kg.

Specimen.Six months after surgery, the patient is symptom free and has no signs of recurrence
![Page 27: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/27.jpg)
LipomaLipoma is one of the commonest benign mesenchymal
tumour in the body composed of mature adipose cells.
It is found in almost all the organs of the body where normally fat exists that is why it is also known as ubiquitous tumour or universal tumour.
Most of the lipomas present as small subcutaneous swellings without any specific symptom.
![Page 28: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/28.jpg)
LipomaGiant lipomas, though rare, can present in thigh,
shoulder or trunk. Clinical features of these giant lipomas are mainly because of their size which includes pain because of stretching of adjacent nerves,(restriction in movements of the part involved or social embarrassment because of mere size of the swelling).
Although definitive diagnosis of giant lipoma can be made only by histopathological examination, but once suspected, other investigations can provide additional information about the tumour.
![Page 29: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/29.jpg)
Lipoma
The characteristics of benign lipoms on ultrasonography, CT and MRI have been well established and even Tc99 DTPA scan have been used to confirm the diagnosis.
![Page 30: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/30.jpg)
LipomaSurgery is the treatment of choice of these giant swellings
due to their tendency to recur and their potential hazard of malignant transformation, other option for treatment of these giant swelling is liposuction.
The dissection of these lipomas is usually easy because of continuous pressure on the surrounding tissue, a well defined pseudocapsule is formed.
Dead space created because of dissection of the giant lipomas is usually drained with the help of a suction drain to avoid collection.
As already mentioned, these tumours have tendency to recur and can have malignant transformation, therefore, should be followed meticulously.

Hemangioma Benign skin lesion consisting of dense, usually
elevated masses of dilated blood vessel. Benign neoplasm characterized by blood vascular
channels. A cavernous hemangioma consists of large vascular
spaces. A capillary hemangioma consists of many small
blood vessels. A collection of dilated small vessels, 3 types: strawberry nevus, port-wine stains, spider nevus

Hemangioma Congenital benign tumour made of blood vessels in the skin. Capillary hemangioma , an abnormal mass of capillaries on the
head, neck, or face, is pink to dark bluish-red and even with the skin. Size and shape vary. It becomes less noticeable or disappears with age.
Immature hemangioma (hemangioma simplex, strawberry mark), a reddish nub of dilated small blood vessels, enlarges in the first six months and may become ulcerated but usually recedes after the first year.
Cavernous hemangioma, a rare, red-blue, raised mass of larger blood vessels, can occur in skin or in mucous membranes, the brain, or the viscera. Fully developed at birth, it is rarely malignant. Hemangiomas can often be removed by cosmetic surgery.

Meningocele
Meningocele (MM):Protrusion of the membranes that cover the spine and part of the spinal cord through a bone defect in the vertebral column.
MM is due to failure of closure during embryonic life of bottom end of the neural tube.
The term spina bifida refers specifically to the bony defect in the vertebral column through which the meningeal membrane and cord may protrude (spina bifida cystica) or may not protrude so that the defect remains hidden, covered by skin (spina bifida occulta).
The risk of MM (and all neural tube defects) can be decreased by the mother eating ample folic acid during pregnancy.

A birth defect involving an abnormal opening in the spinal bones (vertebrae) is called spina bifida. The spinal vertebrae have not formed and joined normally, leaving an opening
![Page 44: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/44.jpg)
A defect which also includes a small, moist sac (cyst) protruding through the spinal defect, containing a portion of the spinal cord membrane (meninges), spinal fluid, and a portion of spinal cord and nerves is called a meningocele, myelomeningocele, or meningomyelocele
![Page 45: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/45.jpg)
Surgical treatment is needed to repair the defect and is usually done within 12 to 24 hours after birth to prevent infection, swelling, and further damage.While the baby is deep asleep and pain-free (using general anesthesia), an incision is made in the sac and some of the excess fluid is drained off. The spinal cord is covered with the membranes (meninges) and the skin is closed over the protruding meninges, spinal cord, and nerves.
![Page 46: Physical signs Symptom- what the patient feels Physical sign- what the doctor finds at clinical examination of the patient’s segments. Symptom is subjective.](https://reader038.fdocuments.us/reader038/viewer/2022103023/56649dd95503460f94acf3d3/html5/thumbnails/46.jpg)
The long-term result depends on the condition of the spinal cord and nerves. Outcomes range from normal development to paralysis (paraplegia).Infants may require about 2 weeks in the hospital after surgery.

Physical signs in head injuryExamination of a case of recent head injuryThe patient is unconscious
Examine the scalp for a wound or local bruising or hematoma
Examine the nostrils and ears for evidence of blood diluted with CSF
Compare the size of the pupils and test their reaction to light
Make a general survey of the body for other injuriesSearch for paralysisPalpate and percuss the hypogastrium for evidence of an
overfull bladderTemperature, pulse rate, RR-charted every half-hour

Head injuryRadiographs of the skull should be taken at
the first opportunity compatible with safety
Brain injury is more likely in the presence of a skull fracture BUT skull fracture of itself does not indicate brain injury

COMA
Coma is a state of absolute unconsciousness in which the patient does not respond to any stimulus
Reflexes are absent, including the corneal and swallowing reflexes.
Semi-coma- the patient responds only to painful stimuli and reflexes are present

SKULL FRACTURESLinear skull fractures, the most common type of skull
fracture, occur in 69% of patients with severe head injury. Usually caused by widely distributed forces.
In rare cases, a linear fracture can develop and lengthen as the brain swells, in what is called a growing fracture.
Diastatic fractures are linear fractures that cause the bones of the skull to separate at the skull sutures in young children whose skull bones have not yet fused. They are usually caused by impact with a wide area such as a wall.

SKULL FRACTURESComminuted skull fractures, those in which a bone is
shattered into many pieces, can result in bits of bone being driven into the brain, lacerating it.
Depressed skull fractures, a very serious type of trauma occurring in 11% of severe head injuries, are comminuted fractures in which broken bones are displaced inward.
This type of fracture carries a high risk of increasing pressure on the brain, crushing the delicate tissue. Complex depressed fractures are those in which the dura mater is torn. Depressed skull fractures may require surgery to lift the bones off the brain if they are causing pressure on it.

Basilar skull fractureBasilar skull fractures, breaks in bones at the base of the
skull, require more force to cause than cranial vault fractures.
Thus they are rare, occurring as the only fracture in only 4% of severe head injury patients.
Basilar fractures have characteristic signs: blood in the sinuses; a clear fluid called cerebrospinal fluid (CSF) leaking from the nose or ears; raccoon eyes (bruising of the orbits of the eyes that result from blood collecting there as it leaks from the fracture site); and Battle's sign (caused when blood collects behind the ears and causes bruising).
