Bacillary angiomatosis (BA) is a rare condition that usually affects immunosuppressed patients. It is a vascular proliferative disorder due to Bartonella henselae or B. quintana. We present here an immunocompetent patient with BA. There was no history of the patient direct or indirect contact with cats.

The well-known immunomodulatory effect of melatonin is observed either as an endocrine, a paracrine or an autocrine response. In mammals, nuclear translocation of nuclear factor κ-light-chain-enhancer of activated...

nocardiosis has been reported increasingly in recent two decades, probably due to improvement in isolation of the organism and increased burden of immune compromised patients. nocardia occasionally has been reported in healthy people. a case series of definitive nocardiosis (2002 to 2010), clinical characteristics, underlying diseases, immune status and in-patient outcome were studied in a tert...

Herpes zoster virus (HZV) reactivation is commonly reported in elderly or immune compromised patients. However, certain presentations are rarely reported in immune competent patients. Here we report a rare case of recalcitrant HZV infection, including 7 reactivations over 3 years, in an immune competent patient. Due to the pain experienced, this patient self-referred to our clinic, and thus byp...
