C, A defining feature is the presence of xanthomatous
(foam) cells in the dermal papillae (hematoxylin-eosin, original magnifications X40 [A], X200 [B], and X400 [C]).
Atypical multiple, papilliform, xanthomatous
, cutaneous neoplasia in a goose (Anser anser).
Therefore, inflammatory reactions are thought to be important in the pathogenesis of this disease.12 Unlike other types of xanthomatous
disorders, patients with XD usually show normal lipid profiles.
Caption: (B) Medium magnification (100x) micrograph showing prostatic glands lined by cells with abundant xanthomatous
cytoplasm with a distinct foamy appearance and uniform nuclei.
In animals from the PTC group, liver presented with lower presence of fat and xanthomatous
macrophages but with intense lymphocytic infiltrate.
On microscopy, the cellular infiltrate is constituted by macrophage-like mononuclear cells, epithelioid histiocyte-like cells, osteoclast-like giant cells, and xanthomatous
The ECD is characterized by xanthomatous
or xanthogranulomatous infiltration of tissues by foamy histiocytes, "lipid-laden" macrophages, or histiocytes, surrounded by fibrosis  (Figure 3A).
Hemosiderin deposition and clusters of xanthomatous
cells were also identified (Figures 3(b) and 3(c)).
This lesion is also known as a plasma cell granuloma, myofibroblastoma, inflammatory myofibroblastic tumor, and xanthomatous
pseudotumor, and it occurs as the result of an inflammatory myofibroblastic proliferation and a pseudosarcomatous fibroinflammatory process.

Microscopically, prominent giant cells and xanthomatous
