R. Soloeta et al., MULTIPLE CLUSTERED DERMATOFIBROMAS - A CA SE-REPORT AND IMMUNOHISTOCHEMICAL STUDY, Annales de dermatologie et de venereologie, 121(6-7), 1994, pp. 482-484
Multiple clustered dermatofibromas constitute an uncommon entity, of w
hich we have collected seven cases in the literature. We observed the
case of a 4-year-old girl, who had dermatofibromas confluent in a cent
ral plaque of fibrous aspect, located in the lumbar region. The immuno
histochemical study showed positive staining for Factor XIIIa antibody
, confirming its origin in the dermal dendrocyte.
