Sm. Hwang et al., Pincer nail deformity and pseudo-Kaposi's sarcoma: complications of an artificial arteriovenous fistula for haemodialysis, BR J DERM, 141(6), 1999, pp. 1129-1132
Pseudo-Kaposi's sarcoma which develops due to arteriovenous fistulae for ha
emodialysis is relatively well known, In contrast, nail changes associated
with pseudo-Kaposi's sarcoma or venous hypertension are rare, We report a n
ovel case of pincer nail deformity associated with pseudo-Kaposi's sarcoma
and venous hypertension, complications of an arteriovenous fistula for haem
odialysis, and review eight similar cases reported in the literature. Most
of the subjects presented with similar findings, having circulatory disturb
ance due to an arteriovenous fistula and/or increased venous pressure, and
swelling, discoloration and papules/nodules of the skin distal to the shunt
. Of the nine patients, three had overcurvature of the nails, in which the
lateral edge of the nail pressed deeply into the lateral nail fold. Pincer
nail deformity associated with pseudo-Kaposi's sarcoma after placement of a
n arteriovenous fistula may be relatively common and should be recognized a
s a specific sign of circulatory disturbance due to the arteriovenous fistu
la.
