Overview
Extranodal
Extranodal means that the primary area of presentation of the
lymphoma is not in the lymph nodes.
Extranodal can be further categorized as primary or
secondary,
with "primary" indicating that the lymphoma first presented
itself in an extranodal site.
Some kinds of extranodal lymphomas are: bone, breast,
eye, oral, skin, etc.

Extranodal
lymphomas: "Lymphomas
do not only only arise in lymph nodes. Many arise [or present] in non-lymphoid
sites such as the skin and gastrointestinal tract. The
gastrointestinal tract is the most common extra-nodal site for
follicular lymphomas, the most common nodal based type of
lymphoma." thedoctorsdoctor.com
What is lymphoma?
Briefly, lymphomas result when DNA
damage or changes occurs to an immune cell (a lymphocyte) that
alters the behavior of the cells. The damage to DNA results in the
abnormal production of proteins that prevents the cells from dying when
they should, or causes sustained rapid cell division that produces
more of its kind. These malignant cells
then may accumulate to form tumors that may enlarge the lymph nodes or
spread to other areas of the lymphatic
system, such as the spleen or
bone marrow. Lymphoma can also spread or first appear outside the
lymphatic system -- and is called extranodal
disease.
The underlying pathology (the type of cell, it's stage of
maturation, it's genetic characteristics, etc.) further classifies the
extranodal lymphoma. These properties may be more relevant to the the
likely behavior of the lymphoma and the best types of treatments.

The low incidence of t(14;18) and favourable outcome encountered in
Extranodal Follicular Lymphoma ( ENFL) in this study is similar to that previously found for primary cutaneous FL.
These results support the concept of a subtype of FL lacking t(14;18) involving the major breakpoint cluster region, and with a propensity to arise at extranodal sites. Despite a high relapse rate, patients with ENFL are more likely to achieve complete remission and may ultimately have a more favourable long-term prognosis than those with equivalent nodal disease.

NCCN: Cutaneous B-Cell Lymphoma Guidelines Debut medpagetoday.com/
Primary cutaneous B-cell lymphoma is unlikely to
reduce a person's life expectancy, but even with definitive
therapy, the disease is likely to recur, doctors said in unveiling
new guidelines for treatment of the disease.
About 1,000 to 1,500 cases of cutaneous B-cell lymphoma occur each
year in the U.S., said Steven M. Horwitz, M.D., of Memorial-Sloan
Kettering Cancer Center in New York and a member of the guideline
panel. But because the disease is rarely fatal, there are tens of
thousands of people living with it.

"Depending on the site of involvement,
ocular lymphoma can be
either intraocular or orbital and adnexal."
Important: Ocular and orbital lymphomas
can be effectively treated. However, how either is best treated can
vary significantly by the area effected, the grade, and the type.
Since ocular lymphoma are uncommon, we feel it's very important to
consult an expert experienced in these neoplasms
for a second opinion at diagnosis and certainly prior to receiving
therapy.

occurring in the conjunctiva, lacrimal gland, eyelid and ocular
musculature.
Primary non-Hodgkin's lymphoma of the orbit is a rare presentation,
representing 8-10% of extranodal NHL and only 1% of all NHL. Generally,
it has an indolent course.
Orbital lymphoma in contrast to ocular
lymphoma is rarely associated with primary central nervous lymphoma."

Regarding new involvement in bone: "A lot of
times when follicular lymphoma involves bone, it does so locally, and
it's an extension of lymph nodes growing into bone.
On the other hand, bone involvement in follicular
lymphoma is generally uncommon, particularly if it's diffusely in many
bones. I've got to watch those terms. Under those circumstances I
always have a healthy suspicion about transformation, but I have seen
patients with follicular lymphoma with multiple bone sites who did not
transform. So you really have to try to get a biopsy that tells you
the answer." Dr.
