most often cervical region , unilateral mostly
asymmetrical, discrete
painless, non-tender
elastic character on palpation ( rubbery)
not adherent to skin
fluctuate in size
Cervical/Supraclavicular (60-80%),Axillary (10-20%) and Inguinal (6-12%)
Lymph node involvement is contiguous. Nodal distribution is centripetal.

Peripheral lymph nodes:
In left supraclavicular LAP is more commonly associated with
abdominal involvement ( splenic involvement) then right side.
Thorax
Anterior mediastinum prime location for NS .
Lung involvement may occur by direct contiguity with direct
involvement or by hematogenous involvement, involvement in form
of nodules and irregular interstitial infiltration.
May presents with pleural effusion due to mediastinal compression
of vascular-lymphatic compression and direct pleural involvement.
SVC syndrome is rarely seen in HL.
![Page 9: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/9.jpg)
Spleen, Liver and Upper abdomen
Spleen, splenic hilar nodes and celiac nodes are earliest
abdominal sites of involvement in infradiaphragmatic HL.
25% spleen not clinically enlarged even harbor occult HL
and half of spleen enlarged to be on physical examination
or on imaging assessment are histologically normal.
Liver involvement is uncommon and always associated
with infiltration of spleen.
Retroperitoneal lymph node
Involvement early in course of inguinal presentation of
HL while relativly late in course of supradiaphragmatic
HL.
![Page 10: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/10.jpg)
Bone marrow
is rarely involved at the time of diagnosis.
Patients with advanced stage disease, systemic
symptoms and MC or LD histology have a
higher risk of bone marrow involvement.
Bone: osseous involvement of HL produces
osteoblastic reaction.
Liver, skin and CNS are rarely involved in HL.
![Page 11: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/11.jpg)
Alcohol-induced pain : Rarely, patients with Hodgkin’slymphoma complain of severe pain following alcoholingestion. The pain typically occurs within a few minutes afterthe ingestion of even a small amount of alcohol. Themechanism is unknown.
Abdominal pain : may be due to splenomegaly, Boweldysfunction due to adenopathy or bowel involvement orhydronephrosis.
Bone pain: in the area of bone destruction or invasion or diffuse marrow infiltration.
Neurogenic pain : by spinal cord compression,plexopathies, nerve root infiltration, meningeal involvement and complicating by varicella zoster.
![Page 12: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/12.jpg)
Symptoms related to mass:
1. Mediastinal mass:
retrosternal chest pain, cough, or shortness of
breath.
2. Retroperitoneal lymphadenopathy
discomfort and pain in the paravertebral or
loin regions, particularly in the supine
position. often with psoas muscle invasion.
![Page 13: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/13.jpg)
CNS involvement rare <1 % .
Bone marrow involvement uncommon (<10 %)
, in HL bone marrow involvement adversely
affects the prognosis.
Pel Ebstein fever is periodic and uncommon
but characteristic of HL.

Patients in developing countries have more ofadvanced disease (>50%) bulky disease (50%) and 'B'symptoms (40-50%) at-initial presentation.
In Western countries, three fourth of newly diagnosedchildren have early disease at presentation (stage I-II)and only one fourth of the patients have advanced(stage III-IV) disease.
The cause for such differences remains unknown.
It might be related to a delay in reporting tothe hospital, or to a more aggressive nature of thedisease, or to an altered host immune responseresulting in more aggressive clinical features.

Stage is the term used to describe the extent of tumor that has spread through the body( I and II are localized where as III and IV are advanced.
Each stage is then divided into categories A, B, and E
A: No systemic symptoms
B: Systemic Symptoms such as fever, night sweats and weight loss
E: Spreading of disease from lymph node to another organ

Diagnosis-Lymphoma
![Page 32: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/32.jpg)
History- a careful history of pt. should be taken,
including especially emphasis on presence of
B- symptoms these –
Unexplained fever
Drenching night sweats
Wt.loss greater than 10% of body wt in last 6
months
![Page 33: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/33.jpg)
Other symptoms- should be noted these-
alcohol intolerance- pain in area of nodal
involvement after taking alcohol occur in about
8% of case of HL
Pruritis
Fatigue
Respiratory problem like- SOB, Dyspnoea etc.
![Page 34: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/34.jpg)
Physical examination- should note-
-Palpable node ( number, size, location, shape,
consistency-(Indian rubbery) , mobility )
-Palpable viscera
![Page 35: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/35.jpg)
CBC, PBF, RFT, LFT, ESR, S.LDH, ALP, S.protein
Hematologic evaluation may reveal-
Anemia
Leucopenia /Leucocytosis
Lymphopenia
Thrombocytopenia-may be indicative BM
involvement
![Page 36: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/36.jpg)
Thrombocytosis- often PNS effect
Anemia,leucocytosis, lymphopenia,
hypoalbumenia,
elevated LDH -adverse prognostic factor
especially if pt. in advanced stage 3-4)
![Page 37: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/37.jpg)
S.ALP level- may be non specific marker of tumor
activity, hepatic& bone marrow involvement and
bone disease
ESR- may correlate with response to treament &
subsequent disease activity & a prognostic factor
for limited disease (stage 1-2)
Other marker- S.Ca+, LDH, beta2 microglobulin
HBV-for chemo.-Rituximab
![Page 38: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/38.jpg)
Chest radiograph – PA & Lateral view
Mediastinal adenopathy may be assess by -
measurement of maximum width of mediastinal
mass divided by maximum intra-thoracic
diameter near the level of diaphragm on
standing PA chest radiograph
When this ratio exceeds 1:3,disease defined as
Bulky
![Page 39: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/39.jpg)
Other definition of bulky mediastinal
adenopathy
A nodal mass > 10 cm & a ratio of mediastinal
mass to chest diameter at T5-6 exceeding 0.35
this employed in EORTC (European
organization for reaserch & treatment of cancer
)
![Page 40: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/40.jpg)
Abdominal & pelvic CT scan- indicated to note the presence of enlarge LN in retro-peritoneal area, hepatospleno-megaly, or focal nodules in spleen & liver.
LN usually enlarged on CT if their short axis measurement exceeds 1 cm
-LN inv. if LA >1.5 cm
or LA >1.1 & SA >1.0 cm
-LN uninv. if both axis <1.0 cm
2-D echocardiography for anthracycline CT.
![Page 41: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/41.jpg)
Usually splenomegaly & hepatomegaly alone
can not represent involvement by HL
Often enlarged spleen not involved at the time
of presentation
But presence of focal nodules usually indicative
of involvement by HL
![Page 42: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/42.jpg)
Overall accuracy rate for detection of HL in
spleen is 58% by CT scan
Sensitivity, specificity, & overall accuracy rate
of CT in identifying nodal disease is -65% ,
92%, & 87%
A CT scan of neck may be indicated if
irradiation to cervical node given, --
to identify their precise location for treatment
planning
![Page 43: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/43.jpg)
Gallium-67 isotope
Affinity for lymphomas
Good sensitivity/specificity
If treatment makes Ga scan negative, good
chance at lasting remission
May find occult disease
![Page 44: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/44.jpg)

PET – positron emission tomography
FDG – 18-fluoro deoxy-glucose
Taken by actively metabolic cells
Good sensitivity/specificity
![Page 46: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/46.jpg)
FDG-PET scan used in initially staging in HL &
largely replaced Gallium imaging for that
purpose
More sensitive than CT & Gallium imaging &
more convenient than Gallium because shorter
duration between injection & scanning ( 1hr.
Vs. 48to72hr )
Useful as follow-up study to evaluate residual
detected by CT scan
![Page 47: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/47.jpg)

MRI– it main value in staging evaluation of
women during pregnency
Bx. a needle bx. of posterior iliac crest bone
marrow may be indicated in pt. with B-symptom
or clinical evidence of sub-diaphragmtic
disease.
Overall incidence of BM involvement by HL
only 5-10%.
![Page 49: Lymphoma clinical feature & dx-Dr.Rajesh](https://reader034.vdocuments.us/reader034/viewer/2022042817/55a73c1c1a28abd0258b4711/html5/thumbnails/49.jpg)

Definition:
Fine needle = 22 gauge or smaller
Useful for :
Reactive conditions e.g. infectious disease
Metastatic tumors
High grade lymphomas

Core needle biopsy is adequate for the
diagnosis of metastatic carcinoma , but for
primary lymphoid disorders so far not
recommended.
Incisional biopsy is also not preferable in
primary lymphoid disorders.
Exicional biopsy of (whole) node with intact
capsule by sharp dissection is highly useful for
demonstration of nodal architecture, therefore
most favorable.

I. Follicular hyperplasia:
Caused by stimulation that activate humoral immunity
Increased and enlargement of large B cell rich germinal centres(secondary follicles) covered by a layer of resting B cell (the mantle zone)
Follicular center cells comprising the large proliferating lymphocytes (centroblasts), smaller cells having cleaved nuclear contour (so-called cleaved cells or centrocytes) and phagocyticmacrophages (cells with pale staining cytoplasm and tingiblebodies), some T cells and others. Eg. rheumatoid arthritis, toxoplasmosis, and the early stages of HIV infection.
It can be confused morphologically with follicular lymphomas . Findings that favor a diagnosis of follicular hyperplasia are
(1) the preservation of the lymph node architecture, with normal lymphoid tissue between germinal centers;
(2) variation in the shape and size of the lymphoid nodules;
(3) a mixed population of lymphocytes at various stages of differentiation; and
(4) prominent phagocytic and mitotic activity in germinal centers.

II. Paracortical (lymphoid) hyperplasia:
Caused by stimulation of cellular immunity
Widening of T cell regions of the node
Paracortical or interfollicular areas containing activated T cells (immunoblasts) and others. viral infections (such as EBV), following certain vaccinations (e.g., smallpox), and in immune reactions induced by certain drugsespecially phenytoin, hydralazine, allopurinol.
III. Sinus histiocytosis or Reticular hyperplasia:
Histiocytes = tissue cells, in this meaning includes macrophages and dendritic cells (Langerhans cells) along the sinusoidsSinus histiocytosis is often encountered in lymph nodes draining cancers and may represent an immune response to the tumor or its products..

Diffuse Large Cell Lymphoma –40- 50% of NHL
Most of B cell origin
Dual age peak: twenties and sixties
Rapidly enlarging, symptomatic mass at a single site
Commonly extranodal: GI, skin, bone, brain – although
liver, spleen and marrow not often involved at
presentation
Requires intensive therapy and CNS prophylaxis.
Express B cell markers-CD19, CD20, CD22, CD79a.
Types-
a. germinal center B cell
b. activated B cell sub-type
c. primary mediastinal

Follicular Lymphomas – 20-40% of adult NHLGenerally low grade
Usually age > 50 years
Characteristic t(14;18) in 90% of cases
Generalized, painless, lymphadenopathy. Spleen and marrow often involved at time of diagnosis (75%).
Long natural history (6-8 years) – but not affected by treatment
Treatment options: watchful waiting, purinenucleoside analogues, monoclonal antibodies to CD20
Becomes aggressive if progress to diffuse lymphoma – but still not treatable .
