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
- Bands of Ladd.
- Cholesteatoma.
Orthopaedic
Gastrointestinal
Hernia sac
General
- Hernia repair.
- Pathologic findings are very usual and if present known to the surgeon.
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:
- One is looking for malignancy (e.g. colorectal carcinoma), especially if that is in the history.
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]
Microscopic
Features:[7]
- Keratinaceous debris - key feature.
- Squamous epithelium.
- Macrophages +/- giant cell (containing keratinceous debris).
- Chronic inflammation (lymphocytes).
Genitourinary pathology
Foreskin
General
Considerations:
- Squamous cell carcinoma.
- Lichen sclerosis.
- Lichen planus.
- Infection.
Microscopic
Features:
- Usu. fibrotic dermis.
- +/-Inflammation.
