From: An unusual case of uterine cotyledonoid dissecting leiomyoma with adenomyosis
Macroscopic and histopathological features of the tumor. a The intrauterine mass contains multiple nodules. b Both extra- and intrauterine components parts consist of numerous ill-defined tumorous nodules, which dissect myometrium in the intrauterine part. All nodules show sparsely distributed swirls of benign smooth muscle cells, with marked hyalinized degeneration, and hydropic change (hematoxylin-eosin staining; object lens magnification, ×1.25). c The neoplastic smooth muscle cells are uniform, with spindle shaped nuclei and eosinophilic cytoplasm (hematoxylin-eosin staining; object lens magnification, ×10). d Masson trichrome staining reveals abundant hyalinized collagen fibers admixed with neoplastic myocyte fascicles in all nodules (object lens magnification, ×10)
