Sporotrichosis is a subacute or chronic dis-
ease that affects animals and humans caused
by the dimorphic fungus Sporothrix schen-
kii.1 An epidemic of sporotrichosis has been
noticed in the city of Rio de Janeiro from
1998 onwards and having the cat as the
main link in the epidemiological chain.2 We
have missed a large proportion of these pa-
tients and adjuvant cryosurgery with liquid
nitrogen3,4 has been performed in patients
that persisted with one or two active lesions
whereas the other healed after 2-3 months
of treatment. This study aims at evaluat-
ing the role of adjuvant treatment in these
patients. Methods: 9 patients (7 women/2
men, mean age 45.8 years-old) with cuta-
neous-lymphatic and fixed sporotrichosis
were selected (Figures 1 and 2). All patients

had isolated Sporothrix schenckii in culture (Figure 3).
Results: Patients underwent monthly sessions of cryosur-
gery with liquid nitrogen with two cycles of 15 seconds
and halo of 5 mm (Figures 4 and 5) with an average of
2.2 sessions (range 1-4 sessions). Five patients had exclu-
sive use of itraconazole for a mean period of 28.8 weeks
(range 4-56 weeks) and after the introduction of adjuvant
therapy were discharged after a mean period of 12 weeks
(range 4-36 weeks). The patient who made use of potassi-
um iodide was discharged after two adjuvant therapy ses-
sions, totaling 12 weeks of treatment. The three patients
who used itraconazole and terbinane, itraconazole used
primarily by an average of 21.2 weeks and due to lack of
response initiated terbinane, which when combined with
adjuvant therapy were discharged aer a mean period of 16
weeks (range 4-28 weeks). In conclusion, cryosurgery with
liquid nitrogen4 used in patients with slower response to
systemic antifungal agents in a few sessions reduces treat-
ment time and thus reducing cost and side eects.
