During the last few years, in our veterinary
practice, we have made interesting observations con-
cerning the homeopathic treatment of a chronic skin
syndrome in cats known as eosinophilic granuloma
complex (EGC).
EGC includes three clinical entities characterized by
various lesions affecting the skin and oral cavity of the
Linear granuloma or eosinophilic granuloma is a skin
condition occurring mainly in young cats and present-
ing as erythematous, alopecic, well-circumscribed,
linear lesions found mainly over the caudal thighs
and in a nodular pattern in the oral cavity. Other sites
include the bridge of the nose, chin, lips and paws.
Eosinophilic Plaque is a well-circumscribed, raised,
exudative lesion that is very pruritic and generally
found over the abdomen or groin. Eosinophilic Rodent
Ulcer is a well-circumscribed, ulcerated lesion most
commonly found on the upper lip of the cat and is
generally non-painful and non-pruritic.
Any combination of lesions, symptoms and loca-
tions can be observed in individual cases. Suspected
aetiologies for EGC are numerous and varied. Under-
lying causes or predisposing factors include al-
lergies (mainly to food, biting insects and inhaled
substances, but also to parasites), infectious diseases,
genetic predisposition and immune-mediated diseases,
and in quite a few cases the cause is unknown.
Diagnosis of EGC is based on history, physical
symptoms, blood tests and histological findings. Full
blood count may reveal peripheral eosinophilia asso-
ciated with parasitic and allergic disorders. Skin biopsy
is the most important diagnostic test, often confirming
a suspected clinical finding. Specific histological
patterns have been associated with the three clinical
entities, all presenting tissue eosinophilia as a constant
finding.
Conventional treatment is mainly symptomatic,
aiming at controlling the suspected underlying infec-
tious or parasitic agent or minimizing the allergic
reaction with corticosteroid, antihistamine or hypo-
sensitization therapies. These treatments do not
usually cure the cat and may have undesirable side
effects. Symptoms often recur if therapy is interrupted.
Avoidance of allergenic factors is problematic too,
since most of them exist naturally in the cat’s
environment. A chronic condition with a significant
incidence in cats, EGC is a pathology that can cause
major discomfort to the cat and upset their owners.
Homeopathic treatment of EGC in cats is usually
based, as in other chronic conditions, on repertoriza-
tion and individual case taking leading to a specific
matching remedy. In some cases, symptomatic reme-
dies are also used.
