Primary tuberculosis of zygomatic bone: A rare case report.

Tubercular osteomyelitis of zygomatic bone is extremely rare. Here we have reported a rarest case of primary tuberculosis (TB) of zygomatic bone in a 20 year male who presented with discharging sinus over right zygomatic region. Anti-tubercular chemotherapy given and patient improved well.

Atypical presentation of aural tuberculosis with complication.

Tuberculosis involving mastoid and ear is an uncommon entity presenting with myriads of non-specific features and difficult to diagnose, being a paucibacillary condition. The involvement of otomastoid compartment is hypothesised to be of haematogenous origin. Rarely it can spread directly via tympanic membrane perforation or via reflux through eustachian tube. The usual picture of presentation tends to be one of indolent ear infection not responsive to usual antibiotic treatment and symptomatology being out of proportion to examination findings. We present a case of aural tuberculosis presenting with zygomatic and Bezold abscess without other symptoms, and the usefulness of GeneXpert test in mycobacterial detection in such paucibacillary conditions.

Micosis invasivas agudas: presentaciones atípicas / Acute invasive mycosis: atypical presentations / Micose invasiva aguda: apresentações atípicas

INTRODUCCIÓN: Las micosis invasivas agudas son infecciones rápidamente progresivas con una alta tasa de morbimortalidad. Se presentan principalmente en pacientes neutropénicos. La neutropenia puede clasificarse en cuantitativa (en neoplasias hematológicas, SIDA, inmunodepresión secundaria a transplantes) o cualitativa (en diabéticos mal controlados). Existen dos formas de presentación: Rinosinusal y extrasinusal. En esta última se describen tres subtipos: Rinoorbitaria (mayor frecuencia), rinocerebral y de partes blandas cervicofaciales. OBJETIVO: Describir dos casos clínicos de pacientes con presentaciones atípicas en las micosis invasivas agudas.

INTRODUCTION: Acute invasive mycosis can be a rapidly progressing infection that exhibits high rates of morbidity and mortality. Most commonly occurs in individuals with hematologic malignancies, particularly in patients who have received bone marrow transplantation. Other compromised patient populations at risk are those on chronic steroids, poorly controlled diabetics, patients with AIDS, and those undergoing chemoradiation therapy. Presentation forms can be rinosinusal and extrasinusal, this last one divided into: Rhinorbital, rhinocerebral and soft tissue affectation. OBJECTIVE: Describe two clinical cases of atypical presentation of acute invasive mycosis.

INTRODUÇÃO: Infecções fúngicas invasivas agudas são rapidamente progressivas, com alta taxa de morbidade e mortalidade. Eles ocorrem principalmente em pacientes neutropênicos. A neutropenia pode ser classificada como quantitativa (em neoplasias hematológicas, AIDS, imunossupressão secundária a transplantes) ou qualitativa (em diabéticos pouco controlados). Existem duas formas de apresentação: Rinossinusal e extrasinusal. Neste último, são descritos três subtipos: rino-orbitário (maior freqüência), tecido mole cervicofacial e rinocerebral. OBJETIVO: Descrever dois casos clínicos de pacientes com apresentações atípicas em micoses invasivas agudas e realizar uma revisão bibliográfica da referida patologia.

Primary tuberculous osteomyelitis of zygoma.

Osteomyelitis of zygomatic bone is rare, and tuberculous osteomyelitis is even rarer. This is the case report of a 3-year-old child presenting with a discharging sinus and swelling on the zygoma, which was initially thought to be orbital cellulitis. After further examination, she was diagnosed as having tuberculosis of zygoma and responded to anti-tubercular chemotherapy.

Osteomyelitis occurring in the zygomatic bone.

Osteomyelitis of bones in the middle third of the face is rare, especially in westernized populations. The actiology is usually due to odontogenic sources or infected fracture sites. An unusual case of osteomyelitis of the zygomatic bone resulting from the use of radiotherapy in the management of recurrent basal cell carcinoma is presented. This illustrates a late complication of therapy for a cancer which commonly occurs in the head and neck region and is rapidly increasing in incidence in the UK.

Candida albicans osteomyelitis of the zygomatic bone. A distinctive case with a possible peculiar mechanism of infection and therapeutic failure with fluconazole.

This report describes a distinctive case of zygomatic candidiasic osteomyelitis in a diabetic patient with oral candidiasis and malar ulceration secondary to topic 5-fluoroacil toxicity that eventually exposed part of the underlying bone. The mechanism of infection may have been self-inoculation of spores from muguet plaques on the oral mucosa to the exposed bone tissue by hand contact. Such a mechanism of bone infection probably should be considered in patients who frequently have oral candidiasis (diabetes, malignancies, and HIV infection) and open lesions of the skin and soft tissues. Treatment with fluconazole was ineffective, but amphotericin B was curative.
