Primary tumours of the heart are uncommon. Various authors estimated their frequency at autopsy as follows: Rand and Sachs (1943), o.5 per cent.; Straus and Merliss (I945), 0.0017 per cent.; Lymburner (1934), o.6I per cent. About three-quarters are benign and about half of the benign tumours are the so-called myxomas. Approximately 70 per cent. of these myxomas arise in the left auricle in the ...

As a general rule, superficial myxoid lesions are benign and deep ones are often malignant, with the important exceptions that intramuscular myxoma is deep and myxofibrosarcoma (also called myxoid malignant fibrous histiocytoma) is classically superficial. These latter two lesions are covered in Chapter 21 and are likely to be sampled on needle biopsies, whereas superficial lesions are typicall...

Vulvar aggressive angiomyxoma (AA) is a rare mesenchymal tumor of the vulva. Due to its slow-growing nature, it is often overlooked and misdiagnosed by primary care providers (PCPs). We describe a case report of vulvar AA in a 38-year-old woman who underwent complete surgical excision of the neoplasm with no evidence of recurrence on a 5-year followup. A literature review follows to provide PCP...
