Part 1:
Classification of leprosy: Borderline
Leprosy (BB)
In a
proportion of patients the clinical signs suggesting
borderline tuberculoid leprosy and borderline lepromatous
leprosy are so well balanced that it is difficult to decide if
the patient is at tuberculoid side or lepromatous side.
Borderline
leprosy tends to be unstable. With time an evolvution towards
borderline tuberculoid or borderline lepromatous side may be
seen.
In active
stage the lesions with not so well defined margins, are always
moderately strongly positive on skin smear examination, even
if without globi (big clusters of bacilli).
The lesions
are many and may be extensive with some tendency towards
symmetrical distribution.
