Rocky Mountain Spotted Fever in a patient treated with anti-TNF-alpha inhibitors.

Rocky Mountain Spotted Fever (RMSF) is a tick-bourne illness, which can be fatal if unrecognized. We discuss the case of a patient treated with an anti-TNF-alpha inhibitor for rheumatoid arthritis who later developed a generalized erythematous macular eruption accompanied by fever. The clinical findings were suggestive of RMSF, which was later confirmed with serology.

Herpes zoster duplex bilateralis in an immunocompetent woman--is gender a risk factor?

Herpes zoster duplex is a rare presentation of herpes zoster in which noncontiguous dermatomes are involved. If both sides of the body are affected, it is called herpes zoster duplex bilateralis; if only 1 side is involved, it is called herpes zoster unilateralis. Usually, this presentation of herpes zoster is associated with some level of immunosuppression.

Paraconiothyrium cyclothyrioides is a recently described coelomycetous fungal species. We present a case in a renal transplant patient with chronic skin lesions of the lower extremities caused by P. cyclothyrioides.

Diffuse Large B-Cell Lymphoma at the Site of a Herpes Zoster Scar.

Herpes zoster, also known as shingles, occurs upon reactivation of a primary infection with varicella zoster virus (VZV). Risk factors for reactivation include stress, older age, and immunosuppression, all of which are associated with a decrease in host immunity. Common complications of herpes zoster include scarring and post-herpetic neuralgia (PHN).
