Case series have not assessed prevalence of CD34 reactivity among cutaneous examples of MFS.

Endocrine disrupting compounds (EDCs), especially those that are estrogenic, are an issue of growing concern because they may ultimately adversely affect wildlife survival. 17-beta-Estradiol and its synthetic counterpart, 17-alpha-ethinylestradiol, two common EDCs, are associated with intersex conditions and impaired male reproductive behavior in fish. Male and female Japanese medaka (Oryzias latipes) were exposed to 10 ng/l ethinylestradiol for 6 months.
