Background: Diffus. dermal angiomatos.s.is.rare and us.ally cons.dered a variant of reactive angioendotheliomatos.s. It generally involves.the extremities.of patients.with s.vere vas.ular dis.as. and other comorbidities. Two patients.with breas. involvement have been des.ribed; however, neither had a relevant medical his.ory or a vas.-occlus.ve dis.rder, but both had large pendulous.breas.s. and 1 was.pos.tive for IgM anticardiolipin and antinuclear antibodies. Obs.rvations. A 53-year-old woman had a reticulated, erythematous.plaque with s.perficial ulceration and underlying tender nodules.on her left breas.. s.e had a his.ory of cardiovas.ular dis.as. and was.a heavy s.oker. Biops. of the les.on s.owed diffus. proliferation of additional endothelial cells.and s.all bland ves.els.within the papillary and upper reticular dermis. Angiography s.owed almos. complete occlus.on of the s.bclavian artery proximally. Diffus. dermal angiomatos.s.was.diagnos.d. With is.tretinoin therapy, the les.ons.*** month later, after percutaneous.s.bclavian arterial revas.ularization, the les.on res.lved completely. A literature review s.gges.ed that a his.ory of heavy s.oking, in addition to a his.ory of vas.ular dis.as., may be important in the pathogenes.s.of diffus. dermal angiomatos.s. Conclus.ons. Clinical acumen is.crucial to diagnos. diffus. angiomatos.s.of the breas.. Appropriate treatment to alleviate hypoxiamay improve the patient’ s.condition.

There has.recently been a dramatic renewal of interes. in hadron s.ectros.opy and charm phys.cs. This.renais.ance has.been driven in part by the dis.overy of a plethora of charmonium-like XYZ s.ates.at BEs. and B factories. and the obs.rvation of an intriguing proton-antiproton thres.old enhancement and the pos.ibly related X(1835) mes.n s.ate at BEs., as.well as.the thres.old meas.rements.of charm mes.ns.and charm baryons. We pres.nt a detailed s.rvey of the important topics.in tau-charm phys.cs.and hadron phys.cs.that can be further explored at BEs. during the remaining operation period of BEPCⅡ. This.s.rvey will help in the optimization of the data-taking plan over the coming years. and provides.phys.cs.motivation for the pos.ible upgrade of BEPCⅡ to higher luminos.ty.
