HYSTORY CLINICAL EXAMINATION

LAB.TESTSIMAGISTIC

INVESTIGATIONS

Symptom- what the patient feelsPhysical sign- what the doctor finds at

clinical examination of the patient’s segments.

Symptom is subjectivePhysical sign is objectiveClinical diagnosis = symptoms + signsFinal diagnosis= symptoms + signs +

lab.tests + investigations.

Surface landmarks

Sebaceous cysts

Swelling - cystic mass - cystic tumor - lumpHairy parts of the body- scalpThe mouth of the seb. gland opens into the

hair follicleIf blocked mouth, seb. gland becomes

distended

Seb. Cyst

History- slow growingSymptoms-a lump that gets scratched when

the patient is combing the hairSuch scratches may get infectedIf the cyst becomes infected it enlarges

rapidly and becomes acutely painful

Seb. Cyst- examination-physical signs

Position-hairy parts of the bodyColor- the skin overlying the cyst normal unless it

is infectedTenderness- not tender unless infectedTemperature-normal except when infectedShape- sphericalSize- variable: mm-4-5 cm.Surface- smoothEdge-well definedComposition- hard depending on the pressure in

the cust “cheesy material”

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.

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.

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.

Specimen- 3.2 Kg.

LipomaLipoma - a benign

tumor of adipocyte origin. •The bright yellow color is typical of fat. •Note the lobulated appearance - typical of this lesion. •This particular tumor arose in the subcutaneous fat (note the small strip of skin ).

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.

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.

Lipoma

CT scan of the right thigh was done which revealed a hypodense mass in the posterior compartment of the thigh beneath the hamstring muscles

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 capsule.

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

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.

Most of the lipomas present as small subcutaneous swellings without any specific symptom.

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).

Definitive diagnosis of giant lipoma can be made only by histopathological examination.

LipomaSurgery is the treatment of choice

The dissection of these lipomas is usually easy because of a well defined capsule.

Dead space created because of dissection of the giant lipomas is usually drained with the help of a suction drain to avoid collection.

LIPOMA

Surgical specimen

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

Cavernous hemangioma

HemangiomaCongenital 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.

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.

Hemangiomas can often be removed by cosmetic surgery.

Strawberry hemangiomaIntradermal, subdermal collection of dilated

blood vesselsCongenital lesion- present at birthLooks like a strawberryOften regress spontaneously in months/years

after birthRubbed or knocked they may ulcerate and

bleed

Strawberry hemangioma

Physical examinationPosition- any part of the body- head/neck>Color- bright or dark redShape- protrude from the skin surfaceSize- usually- 1-2 cm.Surface-irregularConsistence- soft, compressible not pulsatileRelations- confined to the skin, freely mobile

over the deep tissues

Port-wine stain-extensive intradermal hemangioma, mostly venous

PORT-WINE STAIN

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

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

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.Under 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.

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

Head injuryThe patient is conscious or semi-consciousPatient with skull fracture – hospital admissionClose observation: PR, BP, RR, pupil size and

reaction/ every ½ h.Signs of neurological deterioration:

Falling pulse rateReduced respiratory rateFalling GCSDilatation of pupilsLoss of light reaction or developing asymmetry

of pupils

Complications of traumatic brain injuryCranial bleedingCerebral hypoxiaInfectionPosttraumatic intracranial bleeding may be:

- extradural - subdural - intracerebralCT of the brain documents the lesionsLocal brain compression- focal neurological effects

- raised intracranial pressure

Types of skull fracturesLiniar fractures - involve the skull vault,

- overlying scalp bruising or swelling

Depressed fractures - caused by blunt injuries,

- the scalp is severely bruised

Fractures of the base of the skull- anterior fossa

- middle fossa

- posterior fossa

Basilar skull fractures

a fracture of the base of the skull - the temporal, occipital, sphenoid and ethmoid bones.

Such fractures can cause tears in the cerebral meninges - leakage of the cerebrospinal (CSF), hematoma formation and meningitis

Physical signs - pathognomonic for basilar skull fracture.

1. Otorrhea – leakage of CSF from the auditory canal2. Leakage of CSF into the nasopharynx via the eustachian

tube, causing a salty taste. 3. Rhinorrhea – leakage of CSF from the nasal passages4. Hematoma presentation surrounding the orbits and ears as

blood is flushed to the surface of the facial tissues.

5. Bleeding from the nose and ears 6. Deafness, nistagmus, vomitus

7. Battle’s sign is bruising over the mastoid sinus and is a delayed physical finding associated with basilar skull fractures.

8. Hemotympanum (blood behind the ear drum) 9. Periorbital bruising “raccoon eyes”

Fracture of the anterior cranial fossa

Periorbital hematomaSubconjunctival hemorrhageCSF or blood running from the nose

Fracture of the middle cranial fossa

CSF running from the ear or blood escaping from the ear

Bruising behind the ear over the mastoid area

Risk of facial paralysis or deafness

Fracture of the posterior cranial fossa

Deep comaBruising on the posterior wall of the pharynx

Raccoon eyes are always bilateral in closed-head trauma and appear in 2-3 daysBlack eyes associated with facial trauma can affect one or both eyes and appear within hours from injury

Raccoon: medium-sized mammal native to North America

Battle signPatients are prone to meningitis due to CSF leakage and meningeal trauma increasing the microbial portal of entry and menigeal integrity.

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.

SKULL VAULT 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 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.
