Abstract:
Introduction: Chronic expanding haematoma (CEH) is a slowgrowing
reactive lesion that can mimic soft tissue sarcoma (STS)
and that is associated with trauma or surgery in man. CEH has
been reported in dogs following injection or trauma.
Materials and Methods: Six cases of canine CEH were examined.
Anamnesis and follow-up were collected. Tissues were processed
routinely and stained. Microscopical findings in canine CEH were
evaluated and compared with three cases of injection-type panniculitis
(ITP).
Results: CEHs were located on the ischial tuberosity (2/6), flank (2/
6), neck and shoulder and ranged from 3 to 20 cm in diameter. Histology
revealed a central cavity, containing fibrin and erythrocytes,
surrounded by a multilayered capsule composed of an internal
band of immature granulation tissue, an intermediate layer of
perpendicularly oriented vessels and an external fibrous layer infiltrating
adjacent tissues. After surgery, three cases recurred and three
had delayed healing. Three cases of ITP lacked prominent layering,
had a thinner capsule and mild inflammation.
Conclusions: CEH may represent an uncommon evolution of necrotizing
panniculitis that can undergo post-surgical complications and,
because of the infiltrative growth, may need to be differentiated from
STS.
