Epidermodysplasia verruciformis and HPV in ImmunocompromisedDrYusraShabbir
A brief description of a very common Genetic disease caused by Human Papilloma Virus (HPV). Also discussion about HPV in AIDs patients, cancer and renal transplant patients. Useful information, research and treatment options regarding warts for dermatologists and MD students, FCPS, MCPS and nurses. Helpful for exams.
Erythema Multiforme Majus (EM) is an acute eruptive syndrome, rare in children, and almost non-existent in infants. It can be disabling when associated with severe mucosal involvement. It has a favorable prognosis, but with a signifi cant risk of recurrence. EM is probably an immune response induced by various agents, the most common being Herpes Simplex Virus 1 (HSV1). Other infectious diseases may be involved, in particular Mycoplasma Pneumoniae. We describe the case of a 6-year-old girl who was hospitalised for generalised skin rash comprising lesions in rings, associated with bullous lesions, essentially oral without genital involvement. The serology of Mycoplasma pneumoniae was positive for IgM at 3191U/ l,
IgG at 885U/ l, and the serology of HSV was positive for IgM at 120U/l and IgG at 84.3U/ l. The evolution was favorable in a few days following administration of symptomatic treatment (rehydration, mouthwash) and etiological treatment (acyclovir: 500 mg / m² / day and erythromycin 50mg / kg/ day).
The diagnosis of EM secondary to dual infection with Mycoplasma pneumoniae and HSV has never been reported in the literature.

Eosinophilic Ulcer of the Oral Cavity, Approach, and Differential Diagnosissemualkaira
Benign ulcerations of the oral mucosa may have a similar appearance to malignant lesions [1, 2]. There are several conditions, both local and systemic, that can manifest as oral ulcers, and that can correspond, on many occasions, to both infectious and autoimmune causes. Probable etiology can often be determined by a complete medical history and a careful physical examination. However, on several occasions, an exhaustive diagnostic study will be necessary, counting on a range of diagnostic suspicions

Introduction: malignant syphilis is an uncommon form of secondary syphilis.This presentation usually occurs in immunocompromised patients, especially in those ones infected by human immunodeficiency virus (HIV). However, it is known that it might exceptionally affect individuals with normal immune response.
Case report: in this manuscript, we report a case with ocular involvement in a male immunocompetent patient. He had extended skin lesions and conjunctival hyperemia on the right eye. After the laboratorial investigation we confirmed syphilis and excluded human immunodeficiency virus (HIV) infection. Considering he had uveitis, the case was conducted as neurosyphilis.and the treatment was made with Ceftriaxone, followed by excellent clinical response.
Conclusion: given the increasing number of cases of syphilis, in patients with polymorphic skin lesions associated with systemic
symptoms, it is important to exclude immunosuppression and even in immunocompetent.subjects this condition should always be a differential diagnosis.

3. The Abstract
Kaposi Sarcoma (KS) is a multifocal angioproliferative
neoplasm characterized by inflammation and edema.
The pathogenesis of human immunodeficiency virus
(HIV)-associated KS (HIV-KS) is multifactorial.
HHV-8 is an essential factor but not in itself sufficient to
cause HIV-KS, the development of which is influenced by
HIV, by increased production of cytokines and by growth
factors.
4. Oedema of the face, legs and hands is a prominent feature of
HIV-KS and is probably caused by lymphoedema related to the
HIV-KS lesions.
The cases of two HIV-seropositive subjects with KS-associated
facial lymphoedema are reported.
Extensive oral HIV-KS in association with facial oedema in the
absence of anti-retroviral treatment appears to be an indication
of a poor prognosis.
5. Introduction
Kaposi sarcoma (KS) is an endothelial tumor of lymphatic
endothelial origin that affects mucocutanous sites, but may also
involve internal organs.
Human immunodeficiency virus (HIV)-associated KS (HIV-KS) is
the most common tumor in HIV infection and it may occur at any
6. The natural course of HIV-KS is unpredictable. It may be either a mild
or a life-threatening disease but the overall prognosis without
treatment is poor.
Aggressive HIV-KS is associated with extensive intraoral exophytic
lesions, sometimes with oedema and sometimes as in the case of
aggressive HIV-KS at any site, with pulmonary involvement (Related to
lungs)
Lymphoedema associated with HIV-KS commonly affects the face, the
neck, the external genitalia and the lower extremities.
7. Oral HIV-KS lesions are single or multifocal, initially present as macules
(A patch of skin that is discoloured) that may progress to papulo-
nodular (A small inflamed elevation of skin) lesions and eventually
become confluent to form large masses.
The lesions are bluish-purple or red, may be indolent or may be locally
aggressive.
Oral HIV-KS most frequently affects the hard palate (upper surface of
the mouth), the gingivae and the dorsum (posterior part) of the
tongue, and in advanced cases the tumor may progress into the
underlying bone.
8. The Aim
The aim of this presentation is to report that the onset of facial
lymphoedema in two subjects with extensive HIV-KS of the
mouth of some duration who had not received antiretroviral
treatment was rapidly followed by death.
9. Case presentation
Case no. 1
A 28-year-old black male with an unremarkable medical history
presented with numerous nodules on the face, and with
multifocal, purple-red, maculo-papular lesions on the gingivae ,
14. KS was provisionally diagnosed.
Serological tests confirmed HIV infection, and microscopic
examination of a biopsy specimen from the palate showed
pronounced vascular and spindle cell proliferation, slit-like
vascular spaces with extravasated red blood cells.
These findings provided confirmation of the provisional
diagnosis of KS.
The patient refused anti-retroviral treatment and systemic
cytotoxic chemotherapy, and was temporarily lost to follow-up
but returned for the treatment
15. He now presented with severe oedema of the face, an increase
in number of the facial KS lesions, and extensive enlargement of
the oral KS lesions affecting the maxillary and mandibular
gingivae and the hard palate.
The patient was in severe pain, could not eat, and had difficulty
speaking. He again refused any investigations and treatment,
returned home and died two weeks later, the cause of death
being undetermined.
16. Photograph of the face three months after the initial
presentation. Note the oedema of the face, in particular of the
17. Photograph showing the worsening of the palatal lesions (three
months after the initial examination)
18. Case No. 2
A 55-year old HIV-seropositive man with a CD4+ T cell count of 12 × 106/l and
a percentage of total lymphocytes of 2.11%, had extensive cutaneous and
oral lesions as well as pronounced oedema of the face , and the lower
extremities.
Oedema of the face. Note the pronounced periorbital oedema
19. The patient was wasted, had been treated for tuberculosis but
had chronic obstructive lung disease, pulmonary hypertension
with right ventricular enlargement, and intractable
gastroenteritis.
He had developed several cutaneous Kaposi Sarcomata two
months prior to examination.
The patient reported that the facial oedema and the oral lesions
had been rapidly getting worse over the last three weeks.
The oral lesions were exophytic, red lobulated masses affecting
the palate, maxillary gingivae and the dorsum of the tongue.
Microscopic examination of a biopsy specimen from the tongue
showed features consistent with those of KS.
20. Intraoral view showing extensive KS lesions on the hard palate, the
soft palate and the dorsum of the tongue.
22. Lymphoedema can be categorized as primary and secondary.
Primary lymphoedema is rare and is associated with agenesis,
hypoplasia or ectasia of lymphatic channels.
Secondary lymphoedema usually occurs due to damage to, or
obstruction of normal lymphatic channels interfering with
lymphatic flow.
Common causes of secondary lymphoedema include infections
that lead to obliteration of lymphatic Lumina (cavity), extensive
surgical excision of lymph nodes, post surgical scars,
malignancies that start in, or spread to lymph nodes, and
radiation treatment that causes fibrosis, blocking the lymphatics.
23. The development of lymphoedema may be attributed to the
high interstitial protein concentration with increased osmotic
pressure that causes retention of fluid in the connective tissue.
24. Lymphoedema associated with HIV-KS
Lymphoedema may precede the development of HIV-KS; may be
present at the time of diagnosis of HIV-KS; or may develop later
in parallel with the progression of HIV-KS disease.
25. HHV-8 infection of lymphatic endothelial cells and of cells
resident in lymph nodes may cause both damage to lymphatic
channels and enlargement of lymph nodes, with blocks
lymphatic drainage and consequent lymphoedema.
HHV-8 is a necessary factor but not in its own sufficient to cause
KS: but chronic lymphoedema together with HHV-8 may initiate
the development of in-situ KS that with time progresses to
become clinically apparent KS.
26. Our first subject refused hospitalization or any further
investigations or treatment at all, therefore we can only state
that the facial oedema was present but not whether it may have
had a non-HIV/KS related cause.
The second subject was in hospital in the care of physicians who
recorded none of the other possible causes of facial
lymphoedema than HIV-KS.
27. Treatment of HIV-KS associated lymphoedema
Treatment of lymphoedema associated with HIV-KS focuses on
treatment of both the HIV-KS and the lymphoedema.
28. Commentators’ Comments
According to the AIDS clinical trial group staging
classification for AIDS-associated Kaposi sarcoma,
lymphoedema and exophytic HIV-KS oral lesions are
independently associated with poor prognosis.
29. In sub-Saharan Africa, the natural course of HIV-KS in the
absence of HAART is characterized by rapid disease progression
associated with high HHV-8 burden and short life expectancy.
In this geographic region, HIV-KS has reached epidemic
proportions.
HIV-KS in the mouth is common, and subjects with extensive
exophytic oral lesions and tumor-associated oedema have
higher death rates than HIV-seropositive subjects having
exclusively cutaneous lesions.
30. Since there is no cure for HIV-KS, conventionally its treatment
focused on control of tumor growth and palliation.
HAART should always be instituted in HAART-naïve HIV-
seropositive subjects with KS, since it promotes regression of KS
lesions.
However, in about 6.5% of these subjects HIV-KS may flare up
shortly after the introduction of HAART as an immune
reconstitution inflammatory syndrome (IRIS)
31. In light of the cases presented here, it might be advisable to
treat oral HIV-KS with cytotoxic chemotherapy at early maculo-
papular stages when the lesions are still asymptomatic.
Such a treatment protocol might have several advantages.
Firstly, systemic cytotoxic chemotherapy might prevent or at
least delay the development of extensive exophytic oral lesions
that have a poor prognosis;
secondly it might prevent the development of lymphoedema
associated with late stages of HIV-KS.
Thirdly, in the early stages of oral HIV-KS, limited cytotoxic
chemotherapy is sufficient to control tumor growth compared to
more extensive chemotherapy regimen needed to treat
advanced oral HIV-KS.
32. Indeed, systemic chemotherapy given to HIV-seropositive
subjects has the risk of exaggerating the existing state of
immuno-suppression, thus further increasing the susceptibility
to opportunistic infections and neoplasms, however, limited
doses of cytotoxic chemotherapy is not usually associated with
such adverse effects.
33. Million thanks for your all ears.
