Photodynamic therapy for the treatment of erythema, papules, pustules, and severe flushing consistent with rosacea.

We report a case of a 45-year-old woman who presented with facial erythema, papules, pustules, and severe flushing consistent with rosacea. The patient had failed standard pharmacologic treatments. The patient's flushing was so severe that she had undergone an elective sympathectomy. She received 6 sessions of photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA as Levulan Kerastick, Dusa Pharmaceuticals) given at 2-week intervals. Improvement was evident after the second treatment and was considered "excellent" after the sixth treatment. Improvement continued and no flares were observed 1 month after the final treatment.

Erythema nodosum in childhood: evaluation of ten patients.

Erythema nodosum (EN), which is a rare skin manifestation among children, is precipitated by a range of infectious and non-infectious diseases. The purpose of this study was to evaluate the epidemiology, etiology, clinical manifestations and course of EN among children. A total of 10 patients diagnosed with EN between January 2000 and March 2004 at Hacettepe University Ihsan Doğramaci Children's Hospital, Pediatric Infectious Diseases Outpatient Clinic, were studied retrospectively. The study population consisted of five girls and five boys, with a mean age of 8.8 +/- 3.3 years (range, 4-14 years). In five of the 10 children (50%), the etiology of EN was established: three had streptococcal infection and two were diagnosed as primary tuberculosis; the etiology of EN could not be determined in 50% of the cases. The duration of the recovery of lesions varied from 4 to 12 days (mean, 8.2 +/- 2.6 days). Our data confirm the predominance of streptococcal infections among the etiologic factors while also considering tuberculosis as a causative factor among children with EN in Turkey.

Erythema infectiosum following generalized petechial eruption induced by human parvovirus B19.

Parvovirus B19 is a DNA virus responsible for a wide spectrum of clinical illnesses. Among dermatological manifestations, the most common is erythema infectiosum, also known as the fifth disease. In 1990 Harms et al first described a papular-purpuric gloves and socks syndrome (PPGSS) due to parvovirus B19. It is an acute acral dermatosis characterized by an eruption of petechiae and small purpuric papules affecting the hands and feet in a gloves-and-socks distribution. Recently it was observed that PPGSS may be associated with involvement of the peri-oral region and the chin (acropetechial syndrome) and other sites provoking unusual presentation of the rash. We describe a patient with an acral purpura with the features of the "acropetechial syndrome" involving the buttocks, genital and axillary regions who subsequently developed a maculopapular eruption with the characteristics of the fifth disease. Parvovirus B19 DNA was detected by polymerase chain reaction (PCR) both in skin vasculitic lesions and in the serum during the petechial eruption, before the onset of antibodies. The immune response coincided with the development of the exanthem, suggesting a direct role of parvovirus B19 in the pathogenesis of endothelial cell injury.

Necrotic erythema nodosum leprosum.

A 32-year-old fisherman suffering from lepromatous leprosy presented with fever, joint pains, bullous lesions, and multiple well-defined ulcers on the extremities and back of 10-days duration. The bullae ruptured to form ulcers of varying sizes with well-defined margins and necrotic bases. A few of the ulcers had black crusts resembling eschars. An immunofluorescence study ruled out autoimmune bullous disease. Histopathology of a lesion showed features of erythema nodosum leprosum.

Dapsone in the treatment of persistent erythema multiforme.

Erythema multiforme (EM) is usually an acute and self-limited inflammatory reaction of the skin and mucous membranes. Attacks may be sporadic or recurrent, and generally last for 1 to 3 weeks. Rarely, an episode of EM may fail to abate. This continuous and uninterrupted occurrence of typical and atypical lesions is known as persistent EM. We present a case responsive to dapsone.

Clinical course of erythema nodosum leprosum: an 11-year cohort study in Hyderabad, India.

Erythema nodosum leprosum (ENL) or type 2 lepra reactions complicate lepromatous leprosy and borderline lepromatous leprosy. We report an 11-year retrospective case record analysis of 481 outpatients with borderline lepromatous and lepromatous leprosy at the Dhoolpet Leprosy Research Center in Hyderabad, India.. The overall prevalence of ENL was 24%, 49.4% among cases of lepromatous leprosy (LL) and 9% among cases of borderline lepromatous (BL) leprosy. Logistic regression analysis identified LL (odds ratio [OR] = 8.4, 95% confidence interval [CI] = 4.6-15.4, P < 0.001) and BL with a bacterial index > or = 4+ (OR = 5.2, 95% CI = 2.1-12.9, P = 0.001) as major risk factors. The average patient with ENL was male, 34.7 years of age, and had multiple episodes of ENL (mean = 3.1) over an 18.5-month period. Three types of ENL were identified: single acute ENL, multiple acute ENL (repeated discrete episodes), and chronic ENL (continuous episodes). Acute single ENL is rare, accounting for only 8% of cases. Chronic ENL accounted for 62.5% of the cohort. Chronic ENL was of longer duration and more severe. An age > or = 35 years was a risk factor for developing chronic ENL. Patients with chronic ENL were more compliant with multi-drug therapy, especially during the first six doses of multi-drug therapy. Distinguishing these different types of ENL would be useful for patient management and developing improved treatment of these debilitating reactions. Improved strategies for treatment and management of these reactions need to be developed.

Erythema induratum - a hypersensitivity reaction to Mycobacterium tuberculosis.

Erythema induratum (also known as Bazin disease, tuberculosum, tuberculosis cutis indurativa and nodose tuberculid) is a rare condition that produces painful, firm, and sometimes ulcerated nodules on the lower legs. Distinctive and diagnostic histopathology comprises a septolobular panniculitis, necrosis, granulomatous inflammation and vasculitis.

'Flagellate' erythema from bleomycin. With histopathological findings suggestive of inflammatory oncotaxis.

A case of erythema in a 'flagellate' pattern due to administration of bleomycin in a patient with Hodgkin's disease is described. Emphasis is placed on the low dose of bleomycin administered--15 mg parenterally--and the short time interval between drug administration and beginning of symptoms: 24 h. The histopathological findings were consistent with a mechanism of inflammatory oncotaxis: the attraction of tumor cells by the skin perhaps due to the bleomycin accumulated and the trauma caused by scratching subsequent to pruritus.

[Neonatal toxic erythema : clinico-epidemiologic characteristics and recent pathogenic hypothesis].

Erythema toxic neonatorum (ETN) is a common, self-limiting condition of term infants, appearing particularly within the first 48 hours of life. ETN has a worldwide distribution, with a frequency variable from 19% to 72%. Erythematous macules, wheals, papules and pustules in varying combination occur, with crops of lesions waxing and waning and spontaneous resolution within hours to days. It's important the differential diagnosis from other pustular neonatal conditions, some of which are severe. The etiology of ETN remains unknown. Recent studies reveal an activation of immune cells in the lesions of ETN and a high presence of peptide antibiotics, suggesting that ETN is an inflammatory skin reaction to the microbial colonization at birth.

Detection of parvovirus B19 in a case of erythema infectiosum with myositis.

A well documented case of erythema infectiosum is being reported here for the first time from India which was associated with myositis that has not been reported globally. A 9-year-old child presented with moderate to high grade fever, mild anemia, and erythematous rash involving face, trunks and limbs associated with arthralgia, myalgia and myositis. Parvovirus B19 infection was confirmed by detection of IgM antibodies (inhouse ELISA) and DNA (nested PCR) in patient's serum.

Role of azathioprine in preventing recurrences in a patient of recurrent erythema nodosum leprosum.

The pathogenesis of erythema nodosum leprosum (ENL) involves both immune complex deposition and dysfunction of cell mediated immunity. Tumour necrosis factor-alpha (TNF-alpha) plays an important role in its pathogenesis. Thalidomide and corticosteroids are the mainstay of treatment for ENL. However, there are often severe limitations to their use. We report a case of recurrent ENL treated successfully with azathioprine. A 15-year-old unmarried girl with lepromatous leprosy had recurrent ENL for 2 years. She was treated with WHO-MB MDT and prednisolone in doses of 40-90 mg a day for 2-12 weeks. Her condition was inadequately controlled. The patient was therefore treated with thalidomide 300 mg and prednisolone 40 mg. The symptoms subsided after 5 days and ENL lesions healed in 2 weeks. Prednisolone was reduced by 10 mg per week and stopped, while thalidomide was reduced to 100 twice daily after 4 weeks. Azathioprine 100 mg (2 mg/kg per day) daily orally was added to prevent recurrences. Thalidomide was further reduced and stopped after another 4 weeks while she continued with azathioprine in the same doses for 8 months. There was no recurrence of ENL lesions and no side effects of the therapy. MB-MDT was stopped 1 year ago, and she is on follow-up without any relapse. Azathioprine, therefore, appears to be an effective and safe drug to prevent recurrences of ENL.

Infantile erythema elevatum diutinum: report of a vesiculo-bullous case.

Erythema elevatum diutinum (EED) is a localized, low-grade form of leukocytoclastic vasculitis mainly affecting adults, with only a few pediatric cases reported in the literature. The pathogenesis of this dermatosis is unknown, although an Arthus-type reaction to bacterial and viral antigens seems involved. We describe a case of EED in a 9 year-old child suffering from recurrent pharyngotonsillitis induced by Streptococcus pyogenes. Clinical presentation of the dermatosis was atypical, with vesicles and bullae intermingled with red-purple papules and plaques distributed mainly over the extensor aspects of the extremities. Histopathological examination of a vesiculo-bullous lesion revealed a subepidermal bulla containing neutrophils and nuclear dust suggesting dermatitis herpetiformis. Fibrin in vessel walls was observed throughout the dermis. Direct immunofluorescence was negative. A prompt and complete response to sulphone therapy was obtained in conjunction with tonsillectomy. Clinicians should be aware of atypical presentations of EED in children with vesicles and bullae mimicking During's disease.

Cutaneous response to ultraviolet radiation-induced erythema in patients with type A dysplastic nevi.

The effects of an exposure to 6 times the minimal erythemal dose of ultraviolet radiation (UV) were studied using a visual scale and a tri-stimulus colorimeter in 12 sun-tolerant (skin types III and IV) patients with type A dysplastic nevus syndrome. In such individuals, the melanocytic system would be susceptible to neoplastic transformation induced by sunlight. The cutaneous response to a marked UVB erythema has been shown to identify the high-risk patients prone to light-induced skin cancer. This study indicates that the UVB cutaneous susceptibility of patients with type A dysplastic nevi is not significantly different from control subjects, in terms of erythemal and tanning response.

Erythema multiforme in two horses.

Erythema multiforme is reported for the first time in 2 South African horses. Both horses displayed a sudden, fulminant outbreak of raised, non-alopecic and non-pruritic plaques over the dorsolateral aspects of the neck and trunk. In both cases the distribution of the lesions was bilaterally symmetrical. Histopathological findings included hydropic degeneration of basal epidermal cells, eosinophilic necrosis of individual or groups of keratinocytes, intra-epidermal and sub-epidermal cleft formation and mixed, dermal, perivascular infiltrates. An initiating cause could not be identified in either case. Both horses underwent gradual spontaneous remission within 3 months.

Erythema induratum (Bazin's disease).

Four patients with erythema induratum (EI) have been diagnosed at the Dermatology Department within the past two years. All four patients had a history of recurrent painful nodules on their calves for at least three years before diagnosis. Three of the patients, all with positive Mantoux reaction to tuberculin skin tests, had neither a personal or family history of tuberculosis. The other patient who had a six year history of recurrent painful leg nodules developed a tuberculous breast abscess. There was a dramatic response to anti-tuberculous chemotherapy in all four patients but one subsequently had recurrent nodules which spontaneously subsided without further chemotherapy.

Experimental borderline lepromatous leprosy with intraneural erythema nodosum leprosum in a mangabey monkey (Cercocebus atys).

A sooty mangabey monkey (Cercocebus atys) was inoculated with Mycobacterium leprae and developed borderline lepromatous leprosy and intraneural erythema nodosum leprosum. Previously studied mangabeys have developed only disseminated lepromatous leprosy without reactions. This case broadens the spectrum of leprosy seen in experimentally inoculated animals and further characterizes the nonhuman primate model of leprosy.

Studies of human leprosy lesions in situ using suction-induced blisters: cell changes with IgM antibody to PGL-1 and interleukin-2 receptor in clinical subgroups of erythema nodosum leprosum.

To examine the immunopathogenesis of type 2 erythema nodosum leprosum (ENL) reactions in leprosy, we studied cellular and soluble immunologic components of skin lesions in 57 patients with reactions (19 acute ENL and 38 chronic ENL), 61 active patients without reactions, and 33 control patients whose leprosy had been treated and cured. Cells, IgM antibody to PGL-1 and Tac peptide levels were obtained from fluid aspirated from blisters induced by suction directly over representative skin lesions. During ENL reactions: a) the lesions in chronic ENL showed a decreased number of CD8+ (T-suppressor) cells and increased helper/suppressor ratio as compared to those in acute ENL and non-reactional leprosy; b) Tac peptide and IgM antibody to PGL-1 levels were elevated in the chronic ENL lesions; c) and systemic administration of corticosteroids appeared to cause a reduction in the intralesional CD4+ cell population and IgM antibody to PGL-1 but did not change CD8+ cell population and the levels of Tac peptide in the lesions. The elevated levels of Tac peptide were localized in the skin lesions while increased levels of IgM anti-PGL-1 seemed to be filtered from the peripheral blood. We conclude that spontaneous lymphocyte activation in situ, primarily of decreased CD8+ and relatively increased CD4+ cells, are important features of chronic, recurrent ENL reactions and may be an intermittent or cyclic phenomenon during the reaction. Understanding the mechanisms of these spontaneous changes in immunity in leprosy will enlarge our knowledge of reactions and of the underlying determinants of delayed type hypersensitivity and cell-mediated immunity in leprosy, which in turn will allow us to realize the potential for artificially manipulating these responses as proposed with vaccines or immunotherapy.
