Abstract

Objective:

To report a novel mechanism suggestive of early ovarian failure secondary to the anti-tumor hedgehog-pathway inhibitor vismodegib.

Design:

Case report and literature review.

Setting:

Academic and private dermatology and fertility practices.

Patient(s):

A 34-year-old nulliparous woman with locally advanced basal cell carcinomas who became amenorrheic while receiving oral therapy with vismodegib.

Intervention(s):

Physical examination and endocrine evaluation.

Main Outcome Measure(s):

Elevated follicle-stimulating hormone (FSH) and low estrogen in the setting of a normal anti-Müllerian hormone.

Result(s):

FSH was elevated; estrogen was low. Preantral follicles were detected and anti-Müllerian hormone activity was normal. Menses resumed 5 weeks after cessation of therapy.

Conclusion(s):

Vismodegib, a first-in-class inhibitor of the hedgehog signaling pathway is indicated for advanced basal cell carcinoma and is associated with amenorrhea. The mechanism is unknown; it has some features of ovarian failure but preserves ovarian potential through blockading of FSH-receptor–dependent signal transduction. This effect appears to be rapidly reversible upon cessation of therapy. Vismodegib and related compounds may have potential for a role in intervention for gynecologic and endocrine disorders and in therapy for other issues involving FSH-dependent function.
