Small cell carcinoma is a type of carcinoma. It is mostly commonly from the lung; 95% of cases are from the lung.[1]
It may be abbreviated SCC, leading to confusion with squamous cell carcinoma.
Overview
Grouping
May be grouped as:[1]
- Pulmonary.
- Gastrointestinal.
- Genitourinary.
- Small cell carcinoma of the prostate gland - most common small cell carcinoma outside of the lung.[2]
- Ovarian small cell carcinoma of the hypercalcemic type.
- Head & neck.
- Breast.
- Other.
Sites other than lung
General
Classic tumour with paraneoplastic syndromes - may be associated with:[5]
- Syndrome of inappropriate antidiuretic hormone secretion (SIADH).
- Clinical: hyponatremia.
- Paraneoplastic cerebellar degeneration.
- Lambert-Eaton myasthenic syndrome.
Microscopic
Features:
- Small cells -- typically 15-20 micrometers ~ 2x the size of RBC.
- Scant cytoplasm.
- Stippled chromatin +/- smudging of the chromatin.
- +/-Nuclear moulding.
