The complex of myxomas, spotty pigmentation and endocrine overactivity.

We describe a 40-year-old male with acromegaly, multiple and recurrent cutaneous myxomas, spotty cutaneous pigmentation, a mammary myxoma, a large-cell calcifying Sertoli cell tumour of the testis, and an unusual calcifying pigmented neuroectodermal tumour. He presented a combination of clinical and histological features not previously documented within the complex of myxomas, spotty pigmentation and endocrine overactivity, and therefore the findings broaden the spectrum of the syndrome.
