7.4 Specialised histopathology services / Referrals
Histopathology Unit provides specialized histopathology services
in areas as listed above.
Referrals or cases for expert or second opinion are welcome.
i. For consultation :
The client (pathologist or clinician) can communicate directly
with the Pathologist specialized in the respective field.
ii. Referral for expert or second opinion:
For HKL patients that need expert or second opinion, the
requesting doctor
(clinician) is required to fill up the request form as routine
cases and submit it to
Histopathology Laboratory together with the specimen (paraffin
embedded tissue,
stained and/or unstained slides). Paraffin embedded tissue is
preferred if the cases
need further ancillary studies or staining.
For outside cases, the material together with referral letter
should be sent to
Histopathology Laboratory. The request should be directed or
addressed to the
specific Pathologist depending on the specialty. The report will
be emailed to the
respective department.
The general referral cases or cases other than the above listed
subspecialties will
be reported by the pathologist on call on that particular
day.
If the case has been reported elsewhere, report should be viewed
from system LIS.
-
8. SPECIMEN COLLECTION AND CONTAINERS
All specimens for routine histological examination are to be
fixed in 10% neutral buffered formalin
(NBF) in a suitable clean leak-proof container.
The containers should have wide opening and if possible with
screw cap to prevent leakage.
The volume of formalin used must be at least 10 times the volume
of specimen to be fixed. Do
not put large specimen in small containers as this would prevent
proper fixation of the tissue and
also distort the specimen.
All specimen containers should have the same identification
details as that written on the request
forms.
Multiple small specimens such as gastrointestinal biopsies
should ideally be mounted on a piece
of filter paper and immediately put in formalin.
Specimens from different anatomical sites should be sent in
separate containers, properly labelled
and must be clearly itemized in the request form.
For cases that require confirmation of the adequacy of surgical
excision, the margins of the
specimen must be marked or tagged accordingly by sutures or by
diagrammatic representation
of the excised specimen.
Specimen for frozen sections should be sent in a clean container
without fixative.
Specimen for enzyme histochemistry (acetyl cholinesterase)
studies is to be sent fresh
immediately without fixative in closed containers and moistened
with normal saline to prevent
drying.
8.1 Muscle biopsy
All requests for muscle biopsy must have prior arrangement with
the pathologist concerned or
Medical Lab Technologist (MLT) at extension 5605 at least one
day before the procedure.
(Usually the biceps or quadriceps muscle would suffice in most
cases)
Important information to be included in the request form
are:
Creatine kinase level
LDH
Contact no. of treating clinician relevant hospital fax number x
Family history of
similar problems.
For open biopsy:
Remove at least one good cylinder of muscle measuring
1.0x0.5x0.5 cm, the
smaller diameter being the cross-section of the muscle.
For optimal processing muscle specimen must be wrapped with
aluminum foil
and sent fresh in an air tight, dry and clean container.
-
The specimen should be transported in a container containing ice
or gel ice.
(Never use dry ice).
Do not tie the muscle to stretch it and do not put tissue on
gauze.
The laboratory will accept fresh muscle biopsy specimen up to 4
hours upon removal but
please remember that optimal result requires the specimen to be
as fresh as possible.
8.2 Renal biopsy
Prior arrangement with the Pathologist concerned is preferred
for very urgent requests.
Two specimens are recommended for each case for proper
histopathological evaluation, i.e
formalin fixed tissue for ordinary light microscopy examination
and fresh tissue for
immunofluorescent staining.
Renal biopsy tissue for immunofluorescence:
Take at least 5 mm core of fresh tissue.
The specimen should be sent fresh in a clean air tight
container.
If the specimen cannot reach the laboratory immediately, the
fresh tissue should be put in phosphate buffer, properly
packed and transported in ice or gel ice.
Do not put fresh tissue specimen on gauze.
9. DESPATCH AND TRANSPORTATION OF HISTOPATHOLOGY SPECIMEN
Specimens for routine histopathological examination should be
sent in formalin to counter no. 5,
common receiving area (CRA) of Pathology Department.
Fresh tissue specimen for frozen section, immunofluorescent
staining and enzyme histochemistry
such as muscle biopsy should be sent immediately to
Histopathology Laboratory.
Fresh tissue should be properly packed and transported in ice or
dry ice if the specimen cannot
reach the laboratory immediately (especially specimen from other
hospitals).
For frozen section, the specimen should be sent immediately upon
removal to Histophatology
laboratory (Pintu 6). by a doctor who will wait for the
report.
Muscle biopsy specimen should be sent to Histopathology
Laboratory (Pintu 6).
-
10. HISTOPATHOLOGY REPORTS
