GIT Neoplasms
- Squamous cell carcinoma: raised edge
with central ulceration or white plaque
- Oesophagus
- Alcohol, smoking, hot beverages,
nutritional deficiency, HPV
- Middle 1/3 of oesophagus, grey white
plaque in masses or diffuse thicknening
- Insidious onset, 5yr survival 9%
- Dysphagia, odynophagia, obstruction, +/- ulceration
- Alcohol, smoking, hot beverages,
nutritional deficiency, HPV
- Oropharynx
- Anus: HP infection, precursor
= condyloma accuminatum
- Oesophagus
- Adenoma
- Pleomorphic adenoma
of salivary gland
- Oesophagus
- Colon
- Dysplasia: nuclear
hyperchromasia, FAP
- Dysplasia: nuclear
hyperchromasia, FAP
- Appendix
- Pleomorphic adenoma
of salivary gland
- Adenocarcinoma
- Stomach
- Clinical: dyspepsia,
dysphagia, altered bowel
habits, nausea, anaemia
- Intestinal type: bulky & glandular,
Signet ring cell type: diffuse
- Antrum & lesser curvature
- Clinical: dyspepsia,
dysphagia, altered bowel
habits, nausea, anaemia
- Duodenum
- Colon
- Tall columnar cells, variable
differentiation & gland formation
- Insidious development, IDA, occult
bleeding, ab cramps, BM change
- Tall columnar cells, variable
differentiation & gland formation
- Appendix
- Mucocele: benign cyst
- Pseudomyoma peritoneii: slow
tumour, mucus production> ascites
- Obstruction + enlargement
mimics acute appendicitis
- Mucocele: benign cyst
- Stomach
- Lymphoma
- Stomach: lymphocytic
infiltrate in lamina propria
- Cause chronic inflammation:
EBV & H.pylori infection
- Dyspepsia, epigastric pain,
spreads to lymph nodes
- Cause chronic inflammation:
EBV & H.pylori infection
- Small intestine:
Coeliac disease
- Stomach: lymphocytic
infiltrate in lamina propria
- Gastrointestinal
stromal tumour
- Stomach
- Well-circumscribed mass
under mucosa +/- ulceration
- Epitheloid or spindle cell
- Asymptomatic, bleeding, mass effect
- Well-circumscribed mass
under mucosa +/- ulceration
- Stomach
- Carcinoid tumour
- Small intestine
- From endocrine cells, tan polypoid lesions, intramural or
submucosal +/- ulceration, island & trabeculae cell structure
- More common in ileum & jejunum
- Asym, ab pain, metastatic disease, obstruction
- Carcinoid syndrome: ileal tumours release vasoactive substances >
flushing, sweating, bronchospasm, colicky ab pain, diarrhoea
- From endocrine cells, tan polypoid lesions, intramural or
submucosal +/- ulceration, island & trabeculae cell structure
- Appendix
- Small intestine
- Non-neoplastic
- Colon
- Inflammatory polyp: injury
+ regeneration cycles
- Hamartoma: growth of
mature tissues at site where
they normally develop, FAP
- Hyperplastic polyps: decreased
epith turnover in >70yo
- Inflammatory polyp: injury
+ regeneration cycles
- Colon
