Questions |
What is the diagnosis?
Considering the age, gender and typical ivory-white scars, I
think this is a case of Atrophie blanche (AB) or Milian's white
atrophy.
What is the etiopathogenesis? Is it a vasculitis or a vasculopathic
reaction?
"Atrophie blanche is common in large, community-based leg-ulcer
clinics and is clearly related to venous insufficiency…”
(1a)
“Livedo with ulceration (SYN. ATROPHIE BLANCHE) is an
uncommon condition in which ulceration occurs, particularly
in the summer, in association with livedo reticularis of legs..”
(1b)
It seems that there is a controversy about the nature of this
disease. Personally, I think that the original idea of Winkelmann
is still correct about Atrophied Blanche and it is a localized
vasculitis rather than a secondary phenomenon to venous insufficiency.(2)
What about treatment?
Till 6 months ago, the patient was good with conservative therapy
and pentoxyphylline, but recently she developed painful ulcerations
in spite of treatment.
There is a long list of drugs reported to be helpful in this
condition. Nicotinic acid, low-molecular-weight dextran, danazol,
stanazol, heparin, colchicine and antimalarials are among them.
I would like to know which ones are your first and second choices.
Do you approach and manage it as a true vasculitis?

This is a very interesting case. I agree with the diagnosis
of Atrophie Blanche. In my estimation Atrophie Blanche is not
a true vasculitis but a manifestation of a thrombogenic vasculopathy,
being the primary event the formation of hyaline thrombi in
the lumen of small vessels in the upper and mid dermis without
vasculitis. AB appeared to result from a decreased fibrinolytic
activity of the blood (JAAD 1996; 204), platelets shows increased
tendency to aggregate and fibrinopeptide A may be elevated (Clin
Exp Dermatol 1992; 4). Anticardiolipin antibodies and lupus-type
anticoagulant may be present.

Over the years, I have seen a number of these patients and
have not helped most of them. I agree with Cesare. Some of these
patients may have coagulopathies. If so, would they benefit
from anticoagulation; but need to be worked up first. There
are a few experts who can comment on this. I will pass along
their names to Henry who will see if they can comment. With
patient's like this it is important to remember the old saw:
Sometimes, it is more important to treat the patient who has
the disease, than it is to treat the disease the patient has."
Although this is attributed to Osler, I think it is older than
Osler. By the way, the photo of Rasht is beautiful.

This is a valuable teaching case to emphasize several points.
Terminology is a critical component of dermatology clinical
practice and education. A common terminology is important for
effective communication and undertanding a specific disease
process and its treatment, as well as to appreciate and validate
the 'local' or 'teaching center' variability in the use and
interpretation of these clinical terms and associated concepts
.
This case represents a prime example of the evolving usage
and 'migration' of terminologies over time. Milian's atrophie
blanche (early 1900's) bore similarity to livedo reticularis
with summer [winter] ulceration (Feldaker et al Arch Derm 1955
and Circulation 1956) and eventually with the terms livedo/livedoid
vasculitis (Bard, Winkelmann, Arch Derm 1967; Schroeter et al,
Arch Derm 1975). More recently, livedoid vasculopathy (Klein,
Pittelkow Mayo Clin Proc 1992; MaCalmont et al Clin Exp Derm,
1992) has been added to the terminological synonymy. Efforts
are underway to provide an open access, comprehensive dermatology
lexicon, and dermatologists are encouraged to actively participate
in development of the first version of the dermatology lexicon
project (dlp) http://www.futurehealth.rochester.edu/dlp/
or http://www.dermatologylexicon.org
Most cases of livedoid vasculopathy (LV) do not demonstrate
primary, frank necrotizing or lymphocytic vasculitis on biopsy.
Segmental hyalinizing changes and microvascular thrombosis of
vessels are principally observed along with fibrinogen/fibrin
and complement deposition in the vessel, often showing a "donut"
pattern of deposition on immunofluoresence examination.
Not surprisingly,therefore, with the variable terminologies
describing this condition, numerous treatments have been used
as therapy for LV. Nicotinates, aspirin-dypyridamole, pentoxifylline,
danazol or stanozolol, heparin or warfarin, and parenteral fibrinolytic
agents such as alteplase [tissue plasminogen activator] (Klein,
Pittelkow Mayo Clin Proc, 1992) for more severe, recalcitrant
cases have been reported. Most recently, IVIg has been evaluated
as a therapy ( Kreuter et al JAAD, 2004).
LV has been associated with various inflammatory, vascular or
pro-coagulant disease states, including venous incompetence-ulceration,
antiphospholipid syndrome, protein C, S, Factor II (prothrombin
G20210A) and Factor V Leiden-activated protein C resistance,
as well as underlying cutaneous poly(peri)arteritis nodosa.
Even case series of Sneddon Syndrome and scleroderma have been
reported w/ LV or LV-like features (Zelger et al Arch Derm,
1993; Thomas, Winkelmann Arch Derm, 1983).
Other diseases or treatment complications manifest ulcers similar
to LV, including thrombocythemia (Itin, Winkelmann JAAD, 1991)
and prolonged hydroxyurea treatment (Best et al Ann Int Med,
1998) Often heparin or LMW heparin (Jetton, Lazarus JAAD 1983;
Hairston et al, Arch Derm 2003) provides the most consistent
and long term benefit to control more active/chronic LV. Following
fibrinolytic therapy for recalcitrant LV, coumadin/ASA seems
to prevent recurrence of microvascular thrombosis and ulceration.
Various persisting systemic or local vascular inflammatory or
pro-coagulant abnormalities may play significant roles in perpetuating
the underlying pathology causing the chronicity that is typically
observed for LV.
In addition, it is important to have the patient discontinue
all tobacco use and use a high quality elastic compression (30-40
mm Hg) garment to minimize swelling and venous stasis that aggravates
LV.

I agree with the comments that have been made relating to livedoid
vasculopathy (LV). In a young person such as this, there is
likely some hypercoagulable factor responsible for the ulcers,
although often even extensive work-ups don't yield the etiology.
LV is more a vessel plugging phenomenon (vasculopathy) than
a true vascultiis. I agree with the therapeutic suggestions
already made and would echo the benefits of good leg compression,
as with surgical support stockings.
