Pneumocystis
carinii infection of the middle ear and external auditory canal.
Report of a case and review of the literature.
ORL J Otorhinolaryngol Relat Spec. 2003 Jan-Feb;65(1):49-51.
We present
a 50-year-old male with Pneumocystis carinii infection involving the
middle ear and the external auditory canal as the first
manifestation of a previously unknown HIV infection. In case of
therapy-resistant otitis with a polypoid mass in the external
auditory canal histological evaluation should be considered to rule
out malignancy or pathogens, like Pneumocystis carinii, that cannot
be cultured. Oral or intravenous antiprotozoal agents are the
treatment in line with current practice. Exploration of the os
petrosum is never required.

Pneumocystis
carinii is an opportunistic infection found in patients with
impaired immunity. Under favourable conditions the parasite can
spread via the blood stream or lymphatic vessels and cause
extrapulmonary dissemination. We report a case of P carinii
infection presenting as bilateral aural polyps, otitis media and
mastoiditis in human immunodeficiency (HIV)-positive patient with no
history of prior or concomitant P carinii infection.

Extrapulmonary
involvement of organs with the protozoan Pneumocystis carinii is
rare. We describe a case of Pneumocystis carinii presenting as an
erosive aural mass in a young male patient with acquired
immunodeficiency syndrome. As far as the authors are aware such an
example has never been described in a British journal and is the
first case worldwide where otic pneumocystosis has extended into the
middle cranial fossa. We also present a review of the literature on
otological manifestations of Pneumocystis carinii.

BACKGROUND:
Pneumocystis carinii (PC) otitis is a rare opportunistic infection
of the acquired immunodeficiency syndrome (AIDS). Initially hearing
loss and otalgia occur with thickening of the tympanic membrane and
the bordering skin of the ear canal. Otorrhea, ear polyps,
perforation of tympanic membrane, destruction of mastoidal bone, and
participation of cranial nerves are observed. Diagnosis is
established histologically. The treatment of the parasite is by
trimethoprim-sulfamethoxazole combinations. The immunological
situation seems to be better than in PC pneumonia. Due to the
underlying immunological incompetence the infection can not be
expected to limit itself. To prevent severe complications as
sequestrating mastoiditis, early diagnosis and specific surgical and
medical treatment are necessary.
Otic and
ophthalmic pneumocystosis in acquired immunodeficiency syndrome.
Report of a case and review of the literature. Arch Pathol.
Lab Med.1992 May;116(5):500-3.
A case of
primary Pneumocystis carinii infection involving the left middle ear
of a patient with acquired immunodeficiency syndrome is described,
and the literature on the otic and ophthalmic pneumocystosis is
reviewed. Otic pneumocystosis typically presents as a unilateral
polypoid mass, and it is clinically manifested as otalgia, hearing
loss, or, sometimes, otorrhea without evidence of current
respiratory disease or previous Pneumocystis pneumonia. In contrast,
choroidal pneumocystosis usually occurs in a patient with acquired
immunodeficiency syndrome with at least one previous episode of
Pneumocystis pneumonia and aerosolized pentamidine treatment, it is
usually asymptomatic and bilateral, and it may be discovered only
because of other concurrent human immunodeficiency virus-related
ophthalmic disease. The diagnosis is made clinically, and
intravenous antiparasite treatment is successful.

Pneumocystis
carinii is the opportunistic pathogen frequently causing pneumonitis
in the acquired immunodeficiency syndrome. Extrapulmonic
manifestation of P carinii is unusual and is commonly associated
with severe systemic illness, other immune deficiency status,
malignancy, or immune suppression. We describe a case of acquired
immunodeficiency syndrome with manifestations of P carinii otitis
media with severe otalgia and conductive hearing loss.
