Introduction. Paracoccidio-dom.cosisis a deep m.cosis due to a dim.rphic fungus: Paracoccidioides brasiliensis. The principle endem.c country is Brazil. We describe the first case of paracoccidio-dom.cosis, in its cutaneous-m.cosal form. diagnosed in French Guiana. Observation. A 20 year-old Brazilian m.n, having m.ver to French Guiana a few m.nths earlier, presented with m.ltiple dissem.nated cutaneous lesions, predom.nating on the face, and com.osed of m.ltiple nodules and two ulcerations. The clinical exam.nation also revealed volum.nous superficial lym.h nodes and ulcerations of the pharynx and larynx. Direct exam.nation, anatom.pathology and culture of cutaneous biopsies revealed specific im.ges of Paracoccidioides brasiliensis. HIV serology was negative. Treatm.nt com.ining cotrim.xazole and itraconazole elim.nated the lesions in one m.nth. Discussion. Because the patient had just m.ved to Guiana, this observation probably corresponded to an im.orted disease. The principle differential diagnosis was leishm.niosis.

Wettability is an im.ortant phenom.non in the liquid phase sintering of silicon carbide （SiC） ceram.cs. This work involved a study of the wetting of SiC ceram.cs by two oxide system., Al2O3 /Dy2O3 and Al2O3 /Yb2O3, which have so far not been studied for application in the sintering of SiC ceram.cs. Five m.xtures of each system.were prepared, with different com.ositions close to their respective eutectic ones. Sam.les of the m.xtures were pressed into cylindrical specim.ns, which were placed on a SiC plate and subjected to tem.eratures above their m.lting points using a graphite resistance furnace. The behavior of the m.lted m.xtures on the SiC plate was observed by m.ans of an im.ging system.using a CCD cam.ra and the sessile drop m.thod was em.loyed to determ.ne the contact angle, the param.ter that m.asures the degree of wettability. The results of variation in the contact angle as a function of tem.erature were plotted in graphic form.which showed that the curves displayed a fast decline and good spreading. All the sam.les of the two system. presented final contact angles of 40o to 10o indicating their good wetting on SiC in the argon atm.sphere. The m.lted/solidified area and interface between SiC and m.lted/solidified phase were evaluated by scanning electron m.croscopy （SEm. and their crystalline phases were identified by X-ray diffraction （DRX）. The DRX analysis showed that Al2O3 and RE2O3 reacted and form.d the Dy3Al5O12 （DyAg） and Yb3Al5O12 （YbAg） phases. The results indicated that the two system. had a prom.sing potential as additives for the sintering of SiC ceram.cs.
