A case of lymphangiomatosis is described affecting the right pelvic li
mb of an 18-month-old, female Maltese dog. A progressive swelling arou
nd the stifle had developed subsequent to a routine tibial crest trans
position. The swollen area eventually progressed to involve the entire
limb circumferentially, to end abruptly in the mid-metatarsal region.
The skin of the affected area was deep red in colour, devoid of hair,
and had numerous large, thin-walled vesicles that were easily rupture
d and from which a serosanguineous fluid exuded. The swelling pitted o
n digital pressure and showed fluctuant mobility. The microscopic appe
arance of biopsied and post mortem material mimicked that of lymphangi
oma. However, the signalment, clinical presentation and histological f
eatures are consistent with a diagnosis of the recently reported varia
nt of human lymphangiomatosis, lymphangiomatosis of the limb.
