ABSTRACT
Cupping is one of the oldest natural
healing therapies worldwide and is well known as a complementary treatment and
remains in use for many ailments, including dermatological conditions. Cupping
involves applying a heated cup to generate a partial vacuum that mobilizes the
blood flow and promotes effective healing. I report a case who presented with
an interestingly allergic skin reaction post cupping on her back. Using search
words of "cupping," "complication," and "skin
allergy", did not yield any reports were found on PubMed. Therapeutic
efficacy was claimed but not scientifically documented in these reports due to
poor clinical evidence. I am reporting this case report for its exceptional
presentation.

Introduction
Cupping is a form of complementary
and alternative medicine (CAM) that is used in the Muslim world, as well as in
North Africa, the Far and Middle East, Eastern Europe and Latin America. It is
proposed to be used initially by the ancient Egyptians, Greeks and Chinese and
it is dated back to nearly 200 AD.
The technique involves the
application of ignited alcohol-soaked cotton in a glass cup or jar. The
container is then applied to the skin over the area of interest. The area of
skin can either be left as is (dry cupping) or it may be scratched and
otherwise incised with a sharp object, such as a knife (wet cupping).
The cup is left over the site and on
cooling, generates a partial vacuum. This is said to draw “spoiled stagnant
blood and toxins” and other “contaminants” as well as eliminating sluggish flow
which manifest in the skin surface as a bruise. Moreover, cupping is performed
over acupuncture spots in the belief that this stimulates the body's vital
energy.
Clinical
presentation
A healthy Libyan lady in her 30s
presented with acute itchy red beefy, non scaly, non oozing skin lesions over
her back, mainly over both shoulders girdles and lower mid back for the last
three days (Figure 1, 2, and 3). She gave a history of wet cupping performed by
a pious woman in a medical clinic, and was not her first time to have it done
for a pain she has on her lower back. She claimed that the skin allergy
developed straight away after the session and the only thing her medic applied
was an olive oil as a moisturizer after the cupping session. She did not follow
up on treatment though the call centre of the hospital called her many times to
come for a follow-up, but never replied back and thus dropped out.
She was reporting bad backache and
seeking complementary treatment (Figure 1), which resulted in multiple red,
well-defined, rounded red skin lesions over the shoulders and lower mid back.
She never came back for a follow up as instructed.
On examination, there are multiple
red, blanchable erythematous, well-defined, rounded none oozing red skin
lesions over both shoulders girdle and the lower mid back at the exact places
where the cupping was applied. A punch 4 mm was taken and sent for
histopathology which revealed findings coincides with sub-acute spongiotic
dermatitis.
Discussion
Cupping or Hijamaah is a term given
('Hijama' in Arabic is derived from 'hajm' which means 'sucking'), and is old
modality of complementary treatment which is usually carried out by non medical
individuals, such as village elders and “pious” men, who have learnt the
technique from their ancestors, eventually passing it on to the next
generation. Some claimed it is like the Chinese acupuncture where certain
points should be triggered. It has been as well recommended by prophet Mohamed
for its vast benefits.
Cupping therapy as a curative skill
has been developed and applied throughout history and believed to be not an
irritant to the skin. This therapy is considered to be relatively safe with no
systemic reviews documenting negative side effects.
Cupping has a distinctive physical
appearance: round areas of erythema which may become oedematous and ecchymotic
due to capillary leak. In order to cover a larger surface area, the cup can be
moved around over lubricated skin: this creates the effect of linear purpuric
streaks. If the physician is not aware of this practice, these benign lesions
can be mistaken for injuries seemingly inflicted through abuse.
Cupping can cause significant
dermatological issues. The practice has been purported to induce Köebner
phenomenon, commonly seen in cases of psoriasis[1], as well as keloid formation
at cupping sites[2]. Cupping may also exacerbate eczematous areas[3], and may
trigger post inflammatory hyperpigmentation[4], and skin burns locally[5].
Additionally cupping found to lessen post-herpetic neuralgia through its
influences on substance P[6].
When cupping was utilized for
non-specific neck and back pain, it was found to improve symptoms
significantly. There is no definitive conclusion due to high dropout rates[7].
Most of the RCTs in the existing
literature demonstrated no serious adverse effects[8].
This unique case cannot further
explored or investigating due to lack of controlled studies on such cases, plus
what the lady stated could be a mix up about her story and the application of
the olive oil after that.
In the present case, this acute
reaction could be explained as secondary to the cupping maneuver carried out
itself (vigorous suction), breakage up of the skin capillary, an unexplained
body immunological reaction toward the cupping, Olive oil and possibly other
oils associated application ways, skin cutting technique, or simply due to the
repeated cupping and trauma. Although no immunological tests were performed as
no similar history of the incident was reported before in the existing
literature, thus the exact cause remains mystery.
Searching however the existing
literature did not yield a single case report about such a similar incident.
Olive oil is well-known to be therapeutic for many ailments as prophet Mohamed
said and as stated as well in the Holy Quran, and known to be safe on skin. So
how this encountered incident happened remains a mystery to resolve. To the
best of my knowledge, this is the first Libyan lady to be reported of such
incident post wet cupping.
The argument here is that cupping
can be used for treating eczema, atopy and contact dermatitis and what had
happened in this case is contact dermatitis post cupping which mandate a
careful consideration when such cases seeking such a therapy.
In conclusion, evidence based
foundation is lacking and needs a robust research and controlled studies to
affirm the claim. Also the benefits of cupping are difficult to analyse and
interpret as there are no randomized control trials which prove or disprove its
efficacy[9].
Clinicians should also be attentive
of diverse alternative treatment modalities and be prepared to offer
evidence-based advice to the patients when needed in order to not miss such
cases.
