Sarcoidosis is a common systemic, noncaseating granulomatous disease of unknown etiology. The development of sarcoidosis has been associated with a number of environmental factors and genes. Cutaneous sarcoidosis, the "great imitator," can baffle clinicians because of its diverse manifestations and its ability to resemble both common and rare cutaneous(More)
The severe immunosuppression associated with HIV infection increases susceptibility to opportunistic fungi. We describe a primary gangrenous cutaneous infection caused by Rhizopus arrhizus in an HIV-infected intravenous narcotic user. In addition, we review nine reported cases of zygomycosis in HIV-infected patients and discuss the frequency and outcome of(More)
The knowledge of many specific skin diseases that predominantly affect Latinos has been increasing; however, the understanding of common skin disease in Latinos is superficial. There are few prospective studies done in the Latino population and none that differentiate between diverse Latino backgrounds. In view of the expanding Latino population in this(More)
BACKGROUND Sarcoidosis affects the central nervous system more frequently than previously appreciated. The diagnosis of neurosarcoidosis is often delayed, potentially leading to serious complications. Symptoms, when present, are not specific, may be subtle and resemble those of other neurologic diseases. REVIEW SUMMARY During the past decade, significant(More)
We present the first case of lymphocutaneous nocardiosis caused by Nocardia transvalensis and the seventh report of infection caused by this microorganism. The patient was allergic to sulfonamides but responded to amikacin and cefotaxime and later to erythromycin. The treatment and criteria for differentiation of cutaneous Nocardia species infection are(More)
With vastly heterogeneous morphologic manifestations, sarcoidosis is one of the "great imitators" of medicine. Because there is no specific confirmatory test, the diagnosis rests on clinical acumen coupled with supportive information from tissue or blood evaluation and the exclusion of other diseases. The characteristic histologic pattern of noncaseating,(More)
Skin cancer is less prevalent in people of color than in the white population. However, when skin cancer occurs in non-whites, it often presents at a more advanced stage, and thus the prognosis is worse compared with white patients. The increased morbidity and mortality associated with skin cancer in patients of color compared with white patients may be(More)
Raynaud's phenomenon is a common clinical disorder for which patients frequently seek the expertise and care of dermatologists. It is manifested by recurrent vasospasm of the fingers and toes, often associated with exposure to cold temperature or emotional stress. The phenomenon is named after Maurice Raynaud, who, as a medical student, defined the first(More)
Despite its recognition as a distinct granulomatous disease for over a century, the etiology of sarcoidosis remains to be defined. Since the early 1900s, infectious agents have been suspected in causing sarcoidosis. For much of this time, mycobacteria were considered a likely culprit, yet until recently, the supporting evidence has been tenuous at best. In(More)
