Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia, abbreviated DIPNECH, is an uncommon lung pathology that is considered pre-neoplastic by the WHO.[1]
General
- Rare - less than 50 reported based on a 2010 paper.[2]
- Usually women (15 of 19 cases[3]).
- Typically non-smokers (16 of 19 cases[3]).
Clinical:[4]
- Typical patient in 60s.
- Cough.
Treatment:
- Somatostatin analogs[4] - improves cough.
Criteria
Marchevsky and Walts criteria - both 1 & 2 are required:[5]
- Three or more separate small airways pulmonary neuroendocrine cell clusters.
- Each cluster should have five or more pulmonary neuroendocrine cells.
- Three or more carcinoid tumourlets.
Notes:
- The Marchevsky and Walts definition is not universally accepted.
- WHO definition is vague.
Gross
- Multiple small pulmonary nodules.[1]
