[Psammomatous melanotic schwannoma as indicator of a Carney complex].

Within a few months a 31-year-old female patient was diagnosed with a psammomatous melanotic schwannoma, an atrial myxoma and microfollicular adenomas in both thyroid lobes. Therefore, sufficient diagnostic criteria of a Carney complex were fulfilled. The Carney complex is an inherited autosomal dominant disorder with highly variable phenotypes, which was initially described by Carney in 1985 as a complex of myxomas, spotty skin pigmentation and endocrine overactivity. Pathologists should consider this differential diagnosis in reports when confronted with a psammomatous melanotic schwannoma.
