reticulin

 [rĕ-tik´u-lin]
a scleroprotein present in the connective fibers of reticular tissue, closely related to collagen in composition.

re·tic·u·lin

(re-tik'yū-lin),
Name given to the chemical substance of reticular fibers, which were formerly thought to be distinct from collagen by reason of their distinctive structure and staining properties but are now regarded as type III collagen (with its associated proteoglygans and structural glycoproteins).

reticulin

/re·tic·u·lin/ (rĕ-tik´u-lin) a scleroprotein from the connective fibers of reticular tissue.

reticulin

[ritik′yəlin]
Etymology: L, reticulum,
an albuminoid substance found in the connective fibers of reticular tissue.

Data collected included age at presentation, gender, medical history, physical examination, blood and bone marrow investigations done as diagnostic workup for AML patients such as, haemoglobin levels, blood cell count myeloperoxidase (MPO) activity, periodic acid-Schiff (PAS) and reticulin staining as well as the final diagnosis.
Histologically, PXA is characterized by marked cellular pleomorphism including spindle cells, mononuclear or multinucleated giant tumor cells with bizarre nuclei, prominent lipid droplets in cytoplasm, frequent perivascular lymphocytic infiltration, and eosinophilic granular bodies together with a dense reticulin network.
These sections were stained using the Reticulin Method, which enhances basement membranes, and resulted in a black hue of reticulin fibers (modified from Puchtler & Waldrop, 1978; Vidal, 1988).
This was followed by tissue processing, paraffin embedding and sectioning, staining with haematoxylin and eosin (HandE) and reticulin were done routinely.
Reticulin silver impregnation showed an epithelioid-like structure.
In parallel, reticulin staining showed a dense pericellular deposition pattern in mesenchymal regions and was negative in GFAP-positive areas (Figure 4(d)).
In some cases histopathological diagnoses were confirmed using special stains such as: periodic acid-Schiff (PAS), with and without diastase pre-digestion, trichrome and reticulin stains.
The Bone marrow pictures in CML without treatment showing hypercellularity due to excessive proliferation of the granulocytes with myelocytes predominantly and presence of blast cells from <10% to >20% in the bone marrow and peripheral blood according to the world health organization criteria that divide the CML in to chronic, accelerated phases and blast crisis, there is decreased or normal or increased megekayrioposis as well as moderate to marked reticulin fibrosis with presence of small megakaryocyte containing hypolobulated nuclei, sea-blue histiocytes and gaucher cell and these changes are return to the normal state after treatment and the immunohisto-chemistry is used for differentiating the myeloblastic and lymphoblastic crisis of CML [7,8].
Specimens were stained with Masson's trichrome and Sweet's reticulin stain for assessment of fibrosis and structural changes.
