Overview
Due to different phenotypes cowden syndrome is likely to be an underdiagnosed condition. Pharmacologic medical therapy is recommended among patients with cutaneous manifestations in cowden syndrome.
Medical Therapy
- Pharmacologic medical therapy is recommended among patients with cutaneous manifestations in cowden syndrome patients.[1]
- Preferred regimen (1): Acitretin 30 mg/day for cutaneous manifestations.[2][3][4]
- Acitretin should be discontinued once the recurrence of skin lesions are noted.
- Preferred regimen (2): Sirolimus/ rapamycin Oral: Initial loading dose: 5 mg once, followed by a maintenance dose of 3 mg once daily[5][6][7]
- MOA: Inhibiting cell proliferation by inhibiting mTOR
- Sirolimus helps in decreasing mucocutaneous lesions and helps in decreasing the occurrence of mucocutaneous lesions.
- Screening for multiple cancers should be effectively done in the patients with cowden syndrome.
