This article collects ditzels, which are, in the context of pathology, little specimens that are typically one or two slides and usually of little interest.[1]

Ditzels

Gastrointestinal

Neuropathology

  • Vertebral disc - see spine.

Pediatric

Orthopaedic

Gastrointestinal

Hernia sac

General

  • Hernia repair.
  • Pathologic findings are very usual and if present known to the surgeon.
    • Thus, it has been advocated that one ought not examine 'em.[2][3]

Microscopic

Features:

  • Fibrous tissue.
  • +/-Adipose tissue.
  • +/-Mesothelial cells.

Notes:

  • One should not see vas deferens.
  • Things worthy of some comment: granulation tissue, inflammation.

Stoma

See: Colon and Small intestine.

General

  • Reversal of ileostomy or colostomy.

Microscopic

Features:

  • Colonic-type or small intestinal-type bowel wall.
    • Lymphoid hyperplasia (abundant lymphocytes) - very common.
    • +/-Fibromuscular hyperplasia of the lamina propria and submucosa.
  • Skin.

Notes:

Pediatric

Bands of Ladd

General

  • Associated with intestinal malrotation.
  • Removed by Ladd's procedure.

Microscopic

Features:

  • Benign fibrous tissue.

Cholesteatoma

General

  • Squamous epithelium in the middle ear - leading to accumulation of keratinaceous debris.[4]
    • Keratosis obturans - accumulation in the external ear canal - is considered to be a different process;[5] though some consider it a synonym.[6]

Microscopic

Features:[7]

  • Keratinaceous debris - key feature.
  • Squamous epithelium.
  • Macrophages +/- giant cell (containing keratinceous debris).
  • Chronic inflammation (lymphocytes).
