title: Bilateral Gigantomastia, Multiple Synchronous Nodular Pseudoangiomatous Stromal Hyperplasia Involving Breast and Bilateral Axillary Accessory Breast Tissue, and Perianal Mammary-Type Hamartoma of Anogenital Mammary-Like Glands: A Case Report.
abstract: Mammary-type fibroepithelial lesions involving ectopic breast and anogenital region are rare and usually coexist with normal orthotopic breast. We present what we believe to be a unique case of synchronous bilateral gestational gigantomastia resembling fibrous mastopathy, synchronous rapidly growing pregnancy-associated nodular pseudoangiomatous stromal hyperplasia involving right breast and bilateral axillary ectopic breast tissue, and metachronous perianal mammary-type hamartoma involving anogenital mammary-like glands occurring in a 34-year-old patient with facioscapulohumeral muscular dystrophy. Also, we review the literature concerning these lesions.
