Abstract
A 31-year-old Caucasian male with leukocyte adhesion deficiency I and a 20-year history of recurrent, painful cutaneous ulcerations on the extremities presented with fatigue and worsening pain in both legs. He had experienced minimal improvement in his leg ulcers from treatment with systemic steroids, numerous courses of systemic antibiotics, and brief trials of infliximab and mycophenolate mofetil. He was treated with monthly intravenous immunoglobulin infusions. Upon completion of six courses of intravenous immunoglobulin his ulcerations had nearly healed for the first time in a decade.

Abstract
Henoch-Schönlein purpura (HSP) is an immune complex-mediated systemic small vessel vasculitis that is most commonly described in children but may affect patients of any age. Our patient, a 91-year-old man, presented with anuria caused by IgA-mediated nephropathy; he later developed cutaneous leukocytoclastic vasculitis, thereby meeting the criteria for a diagnosis of HSP. This case is unique because of the patient's initial presentation with anuria, the possible underlying malignancy associated with his HSP, and his advanced age.

Abstract
PURPOSE Improvements in imaging technologies have dramatically increased the ability to accurately diagnose and treat many urological disease processes. As urological patients often have chronic kidney disease, the well characterized nephrotoxicity of contrast induced nephropathy when using iodine based contrast materials has long been a concern. With the development of gadolinium based contrast agents it seemed that the concern regarding nephrotoxicity had been resolved. In 1997 a new disorder, nephrogenic systemic fibrosis, appeared in patients with severe renal failure. Nephrogenic systemic fibrosis is a serious and potentially devastating disorder characterized by progressive thickening and hardening of the skin and other body tissues, and complicated by flexion contractures of the joints. MATERIALS AND METHODS We performed a survey of the available literature on nephrogenic systemic fibrosis and magnetic resonance contrast media. We focused on mechanisms in the development of nephrogenic systemic fibrosis as well as its association with magnetic resonance contrast media, disease treatment and prevention, and its relevance to clinical urology. RESULTS An association between nephrogenic systemic fibrosis and gadolinium based contrast agents has been reported. Gadolinium is a toxic metal and it must be chelated to be a safe injectable contrast agent. It is now hypothesized that the majority of nephrogenic systemic fibrosis cases present with gadolinium based contrast agent exposure as the triggering factor, although this mechanism has not been elucidated. As gadolinium enhanced magnetic resonance imaging is an important tool in the diagnosis and surveillance of urological diseases, the severe consequences of nephrogenic systemic fibrosis demand that practicing urologists understand and know its history and treatment strategies. CONCLUSIONS This review provides clarification of the gadolinium based contrast agent characteristics, tissue interactions that lead to the development of nephrogenic systemic fibrosis, prevention possibilities and available treatment options.

Abstract
Facial papules (bumps) confront the general practitioner during every face-to-face meeting with the patient. Increased awareness and recognition of the facial papules that represent cutaneous signs of internal malignancy will allow an early, aggressive workup and treatment of any associated cancer. This article details the clinical presentation, etiology, pathologic findings, and associated malignancy for such presentations. A skin biopsy for histopathologic diagnosis is necessary to distinguish these clues to underlying malignancy from the numerous benign lesions that cause facial papules.

Abstract
Bullous pyoderma gangrenosum begins as a bulla, nodule or nonulcerated erythematous plaque that blisters or ulcerates to form a superficial ulcer surrounded by a hemorrhagic, bullous border, which is surrounded by a blue-gray halo. Bullous pyoderma gangrenosum is most commonly associated with hematologic malignancies, specifically, acute myelogenous leukemia (AML). We report a patient whose initial presentation with bullous pyoderma gangrenosum prompted the appropriate diagnostic evaluation and confirmation of AML, which was ultimately fatal. We emphasize that a thorough hematologic investigation, including bone marrow biopsy, should be performed in all patients who present with lesions clinically suggestive of bullous pyoderma gangrenosum because the skin lesion may be the only indicator of the underlying hematologic disorder.

Abstract
Epidermodysplasia verruciformis (EV) is a rare autosomal recessive genodermatosis with an increased susceptibility to specific human papillomavirus (HPV) genotypes. Classically, this viral infection leads to the development of tinea versicolor-like macules on the trunk, neck, arms, and face during childhood, and over time, these lesions can progress to squamous cell carcinoma. More recently, an EV-like syndrome has been described in patients with impaired cell-mediated immunity. We describe two cases of EV-like syndrome in HIV-positive patients, review all previously reported cases of EV in patients with impaired cell-mediated immunity, introduce the term "acquired epidermodysplasia verruciformis" to describe EV developing in the immunocompromised host and examine the limited treatment options for these patients.

Abstract
PURPOSE To determine the incidence and associated risk factors of nephrogenic systemic fibrosis (NSF) in patients who undergo gadolinium-based contrast agent (GBCA)-enhanced magnetic resonance (MR) imaging. MATERIALS AND METHODS Institutional review board approval was obtained for retrospective review of the medical records from two hospitals to identify all cases of biopsy-confirmed NSF and all patients administered a GBCA from January 1, 1997, to June 30, 2007. Informed patient consent was not required. The incidence of NSF was calculated for patients who received a standard dose of GBCA, patients who received a high dose, and subgroups of patients with renal impairment. RESULTS Fifteen patients developed NSF after gadolinium-enhanced MR imaging. All of them had an estimated glomerular filtration rate (eGFR) lower than 30 mL/min, and 11 had acute renal failure or acute deterioration of chronic renal failure. The incidence of NSF after gadolinium-enhanced MR imaging without screening for renal function was zero of 74,124 patients with the standard dose of GBCA and 15 (0.17%) of 8997 patients with the high dose (P < .001). The NSF incidence associated with a high dose of GBCA increased to 0.4% in patients in a chronic hemodialysis program and to 8.8% in those who had an eGFR lower than 15 mL/min but were not undergoing hemodialysis (P < .001). The NSF incidence in the patients with acute renal failure who received a high dose when their creatinine level was increasing was 19% (11 of 58 patients) when hemodialysis was delayed for longer than 2 days. More patients with NSF had proinflammatory events, and compared with patients without NSF, these patients had lower pH, younger age, lower eGFR, elevated serum phosphorus levels, and a longer delay between GBCA injection and hemodialysis. CONCLUSION For patients with an eGFR lower than 15 mL/min, hemodialysis helped to prevent NSF. For patients with an eGFR lower than 30 mL/min who received a high dose of GBCA, acute renal failure, delayed hemodialysis after contrast agent injection, proinflammatory events, and hyperphosphatemia were associated with increased risk of NSF.

Glomus tumor masquerading for 22 years as osteoarthritis of the hip. Cutis 2008; 81:339-342. [PMID: 18491482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/26/2023]
Abstract
Glomus tumors are rare benign mesenchymal neoplasms that account for less than 2% of soft tissue tumors. These neoplasms typically are small nodules less than 1 cm in diameter, associated with pain that is exacerbated by tactile stimulation and cold hypersensitivity. We present a case of a large glomus tumor of the left lateral hip associated with a long history of severe pain of the left hip interfering with ambulation. Chronic pain as a result of a subcutaneous glomus tumor is rare and frequently misdiagnosed. In the case reported, a solid glomus tumor presented with 22 years of unilateral hip pain attributed to posttraumatic degenerative joint disease. Excision of a 4 x 3-cm nodule resulted in complete resolution of tenderness and joint pain. Subcutaneous glomus tumors can have unusually large size and location and should be considered in the differential diagnosis of chronic, atypical, or treatment-resistant joint pain.

Abstract
BACKGROUND Dengue fever is the most common identifiable cause of acute febrile illness among travelers returning from South America, South Central Asia, Southeast Asia, and the Caribbean. Although the characteristic exanthem of dengue fever occurs in up to 50% of patients, few descriptions of it are found in the dermatology literature, and discussions of how to distinguish the dengue exanthem from other infectious disease entities are rare. Chikungunya fever is an emerging infectious disease now seen in returning US tourists and should be considered in the differential diagnosis of dengue fever in the appropriate patient. OBJECTIVE The purpose of our study was to report two cases of dengue fever among returning US tourists, provide a review of dengue fever, offer an extensive differential diagnosis of dengue fever, and raise awareness among dermatologists of chikungunya fever. METHODS This study includes clinical findings of two returning travelers, one who traveled to Mexico and the other to Thailand, complemented by a discussion of both dengue fever and its differential diagnosis. LIMITATIONS Limited to 2 case reports. CONCLUSION Dengue fever should be considered in the differential diagnosis of fever and rash in the returning traveler. Dermatologists should be aware of the distinctive exanthem of dengue fever. Recognition of the dengue fever rash permits a rapid and early diagnosis, which is critical, as dengue fever can progress to life-threatening dengue hemorrhagic fever or dengue shock syndrome.

Abstract
An 88-year-old man from the Dominican Republic with a history of gastric adenocarcinoma was admitted with one month of fatigue, anorexia, weight loss, and abdominal pain. The dermatology department was consulted to evaluate an asymptomatic, shiny, firm, red nodule on the lower left chest, with an expanding rim of erythema. Skin biopsies were performed from the nodule and surrounding rim of erythema, which were both diagnostic of peripheral T-cell lymphoma (PTCL). This case is a unique example of PTCL with erysipelaslike spread.

Abstract
Mycetomas are chronic, progressive infections caused either by fungi (eumycetoma) or filamentous bacteria (actinomycetoma) and are characterized by the triad of draining sinuses, tumefaction, and the presence of macroscopic grains. We describe a case of eumycetoma in a cardiac transplant recipient caused by the soil saprophyte Acremonium species. This represents only the fifth case of eumycetoma reported in a solid organ transplant recipient. With the population of immunosuppressed patients and the incidence of invasive fungal infections increasing, consideration should be given to unusual saprophytic fungal infections as emerging opportunistic pathogens.

Abstract
Malignancy is a well-known cause of cutaneous vasculitis. The occurrence of neoplasia and Henoch-Schönlein purpura (HSP) is rare and poorly understood in adults. A total of 31 cases have been reported in the world literature of adult malignancy-associated HSP. Patients were overwhelmingly male (94%) with a mean age of 60 years and presented predominantly with solid tumors (61%). The most frequent tumors were lung (nonsmall-cell) (n = 8), multiple myeloma (n = 5), prostate (n = 5), and non-Hodgkin's lymphoma (n = 3). The majority of patients (55%) developed HSP within 1 month of cancer diagnosis or detection of metastases. We present 3 cases of adults who, in the absence of known precipitating factors, developed HSP within 2 months of diagnosis of a solid tumor or metastases. We recommend that adults, especially older men who present with unexplained HSP, be evaluated for occult neoplasm. We also advise that patients with a known history of malignancy who present with HSP be evaluated for metastatic disease.

Patients undergoing cardiac transplantation are routinely screened for prior exposure to Treponema pallidum, the bacterium implicated in syphilis. Although acute syphilis typically presents with a painless genital chancre, chronic syphilis can manifest in protean forms and linger undiagnosed. Left untreated, syphilis can cause multi-system disease, particularly irreversible neurologic damage. We describe a case of cutaneous secondary syphilis, neurosyphilis and luetic hepatitis in a cardiac transplant patient.

Abstract
BACKGROUND Rickettsialpox is a self-limited febrile illness with skin lesions that may be mistaken for signs of potentially more serious diseases, such as cutaneous anthrax or chickenpox. The cluster of cutaneous anthrax cases from bioterrorism in October 2001 likely heightened awareness of and concern for cutaneous eschars. OBJECTIVES To apply an immunohistochemical technique on paraffin-embedded skin biopsy specimens for diagnosing rickettsialpox, and to compare the reported incidence of rickettsialpox before, during, and after the cluster of cutaneous anthrax cases. DESIGN Case series. SETTING Dermatology department in a large tertiary care hospital in New York City. PATIENTS Eighteen consecutive patients with the clinical diagnosis of rickettsialpox from February 23, 2001, through October 31, 2002. MAIN OUTCOME MEASURES Results of immunohistochemical testing of skin biopsy specimens and of serological testing. RESULTS Immunohistochemical testing revealed spotted fever group rickettsiae in all 16 eschars and in 5 of the 9 papulovesicles tested. A 4-fold or greater increase in IgG antibody titers reactive with Rickettsia akari was observed in all 9 patients for whom acute and convalescent phase samples were available; 6 patients had single titers indicative of rickettsialpox infection (> or =1:64). Of the 18 patients, 9 (50%) presented in the 5 months following the bioterrorism attacks. CONCLUSIONS Rickettsialpox remains endemic in New York City, and the bioterrorism attacks of October 2001 may have led to increased awareness and detection of this disease. Because rickettsialpox may be confused with more serious diseases, such as cutaneous anthrax or chickenpox, clinicians should be familiar with its clinical presentation and diagnostic features. Immunohistochemical staining of skin biopsy specimens, particularly from eschars, is a sensitive technique for confirming the clinical diagnosis.

Abstract
Nephrogenic fibrosing dermopathy or scleromyxedema-like illness of renal disease is a recently reported disorder. It manifests as scleromyxedema-like skin lesions without associated paraproteinemia, occurring in the setting of renal disease. In the majority of cases skin lesions of nephrogenic fibrosing dermopathy develop after hemodialysis or renal transplantation; however, the origin is still unknown. We report 4 new cases of nephrogenic fibrosing dermopathy and review the literature. The clinical and histopathologic features, differential diagnosis, possible etiology, and treatment options are reviewed.

Abstract
We report the clinical and molecular findings in a patient with a mild form of recessive dystrophic epidermolysis bullosa and aortic insufficiency. To our knowledge, this is the first report of association between dystrophic epidermolysis bullosa and abnormalities of the aortic valve. Analysis of the COL7A1 gene has revealed two new mutations, a 20-bp duplication and a splice site mutation.

Abstract
Acute infectious purpura fulminans is a rapidly progressive syndrome of hemorrhagic skin necrosis associated with acute infection and disseminated intravascular coagulation. We report 5 cases of purpura fulminans and briefly review the literature. All cases were associated with encapsulated organisms (Streptococcus pneumoniae or Group A streptococcus), and 4 of the 5 patients had asplenism or functional hyposplenism.

Abstract
Invasive aspergillosis is uncommon in immunocompetent hosts but is the second most common opportunistic fungal infection in immunocompromised patients. There has been a dramatic increase in the incidence of life-threatening aspergillosis during the past 2 decades, and the morbidity and mortality of these infections despite antifungal therapy remain unacceptably high. We describe a patient with amphotericin B-resistant Aspergillus flavus successfully treated with caspofungin, an agent belonging to a new class of antifungal drugs. Caspofungin shows great promise in the treatment of invasive aspergillosis.

Abstract
Here we report a case of vesiculobullous adult T-cell lymphoma/leukemia (ATLL); to our knowledge the first such report of this presentation. We emphasize the difficulty in clinically distinguishing ATLL from cutaneous t-cell lymphoma. The case is further distinguished by the simultaneous presentation of human T-cell lymphotropic virus-1-related myelopathy in this patient, an unusual occurrence.

Linear porokeratosis with underlying bony abnormalities. Cutis 2002; 69:309-12. [PMID: 12080953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/25/2023]
Abstract
A 58-year-old woman with linear porokeratosis involving the right hand and arm had distal digital narrowing and nail dystrophy with radiographic changes. Whereas isolated cases of bone resorption and flexion deformities with porokeratosis of Mibelli are known to occur, to our knowledge, bony abnormalities in association with linear porokeratosis have not been reported.

Abstract
A 34-year-old woman presented with a slow growing nontender nodule on her left index finger that had been present for 2 years. The tumor was excised and was histologically determined to be a myxoid neurofibroma. We report this case because of the rarity of both the tumor and its periungual location and to provide a review of the literature.

Concurrent herpes simplex type 1 and varicella-zoster in the V2 dermatome in an immunocompetent patient. Cutis 2001; 68:120-2.

Abstract
A unique feature of herpesviruses is their ability to establish latent infection within the nervous system by colonizing peripheral sensory ganglia, which results in subsequent episodic outbreaks of infection triggered by precipitating events. Despite the latent nature of both herpes simplex virus type 1 (HSV-1) and varicella-zoster virus (VZV) within these sensory ganglia, simultaneous outbreaks of these viruses are uncommon. This is generally attributed to the differing reactivation features of these 2 viruses. Four cases of concurrent HSV-1 and VZV infection are described in the literature. We report concurrent infection of HSV-1 and VZV within the same V2 dermatome in an immunocompetent patient.

Kwashiorkor in patients with AIDS. Cutis 2001; 67:321-4, 327. [PMID: 11324396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/19/2023]
Abstract
Kwashiorkor, a form of severe protein-energy malnutrition that entails loss of lean body weight, occurs endemically among children in many parts of the world but also has been documented in adults. We report a case of kwashiorkor in an HIV-positive adult male. Cutaneous findings are striking, and skin, hair, and nails are affected. Although kwashiorkor occurs in patients with HIV-AIDS, the skin manifestations have not been emphasized in the dermatologic literature. Indeed, dermatologists may play a vital role in diagnosing this treatable condition.
