==Granulation tissue== | |||
===Microscopic description=== | |||
The section shows edematous, well-vascularized fibrous tissue with abundant plasma cells and abundant neutrophils. At the center of the lesion are hemosiderin-laden macrophages and at the periphery multi-nucleated giant cells. No foreign material was identified with polarization. | |||

Soft tissue, left ear ("left ear keratosis"), excision - keratinaceous debris. | |||
==Cholesteatoma 1== | |||
===Microscopic description=== | |||
The section shows lamellar keratin, abundant reactive histiocytes and multinucleated giant cells. Lymphocytes and plasma cells are present. There is dystrophic calcification. Fragments of bone are seen. | |||

==Cholesteatoma 2== | |||
===Microscopic description=== | |||
The section shows lamellar keratin, a fragment of squamous epithelium and fragments of bone. No significant inflammation is identified. | |||
===Final diagnosis=== | |||
Soft tissue, left ear ("left ear keratosis"), excision - keratinaceous debris, squamous epithelium and bone (consistent with cholesteatoma). | |||
== Stoma == | |||
===Microscopic description=== | |||
The sections show mature squamous epithelium with parakeratosis, and colonic-type mucosa with focal lymphoid hyperplasia and reactive epithelial changes. The colonic-type mucosa has focal paneth cells, crypt dilation, mild crypt distortion and fibromuscular hyperplasia of the lamina propria and submucsoa. Foreign body-type granulomas (suture granulomas) are present in the lamina propria. Normal bowel wall smooth muscle is present. Ganglion cells are present. | |||

===Micro=== | |||
The sections show a paucicellular nail plate, and a thin layer of squamous epithelium with | |||
keratinization and partial retention of the nuclei (parakeratosis). There is also a small | |||
amount of fibrin. No pigmentation is apparent with Prussian blue and Fontana-Masson | |||
staining. No melanocytes are apparent. No nuclear atypia is apparent. No mitotic activity | |||
is identified. No microorganisms are apparent. No significant inflammation is apparent. | |||
