The cellular findings in a pathologic brain bleed include erythrophages and siderophages. See Figure 1.
(d) The internodular tissue consisted of dense fibrous tissue with myxoid areas with siderophages and scattered plump myofibroblasts, plasma cells, and lymphocytes.
Histopathology of the biopsy specimen revealed fatty and connective tissue infiltrated by focal clusters of siderophages and mononuclear cells together with endometrial glands surrounded by endometrial stroma, which confirmed the diagnosis of endometriosis.
In addition, as the tumours are usually infiltrated by large numbers of siderophages and histiocytes, and display cellular degenerative changes, including nuclear atypia and pleomorphism, along with a tendency to nuclear palisading [1], malignancy may be erroneously diagnosed [4].
On the cytocentrifuge slide, several erythrophages and siderophages are seen.
Alveolar hemorrhage is diagnosed most easily when there are alveolar siderophages indicative of past bleeding into the alveoli with subsequent macrophage processing of the red blood cells.
Some small foci of siderophages and very few microcalcifications were present (Figure 5, D).
This neoplasm also has a more heterogeneous cell population than AFH (often containing giant cells and siderophages), lacks a surrounding lymphoplasmacytic infiltrate, and is desmin negative.
The myocardium demonstrated a transmural subacute infarct characterized by fibrovascular granulation tissue with siderophages and scattered plasma cells.
There are numerous red blood cells, and the intervening stroma is fibrosclerotic or myxoid, with scattered myofibroblasts, siderophages, and inflammatory cell infiltrates.
