Peutz-Jeghers syndrome
Peutz-Jeghers syndrome, abbreviated PJS, is a constellation of findings inherited with an autosomal dominant pattern due to a defect in the STK11 gene.[1]
Clinical
Features:[2]
- Melanocytic macules.
- Lips, buccal mucosa, and digits.
- Multiple Peutz-Jeghers polyps.
Increased risk of various neoplasms - primarily:
- Breast and gastrointestinal cancer.[3]
- Others tumours:[4]
- Granulosa cell tumour.
- Sertoli cell tumour - esp. with calcification.
Reported associations:
- Associated with (ovarian) sex cord tumour with annular tubules (SCTAT).[5]
Microscopic
- Frond-like polyp with all three components of mucosa:
- Muscosal epithelium (melanotic mucosa, goblet cells).
- Lamina propria.
- M. mucosae.
