1/32. Accentuated viral exanthems in areas of inflammation. Types of lesions and patterns of distribution aid in the recognition of viral exanthems. Varicella and hand-foot-and-mouth disease can appear atypically in areas of inflammation. We describe 5 cases of morphologically altered exanthems that localized early and preferentially to areas of inflammation. ( info) |
2/32. granuloma gluteale infantum: a case report. granuloma gluteale infantum is a benign disorder with the clinical appearance of "granulomatous" nodules involving the diaper area. It is an uncommon disorder considered a complication of primary irritant diaper dermatitis. A 6-month-old boy with reddish-purple oval nodules located on the right inguinal fold and right buttock diagnosed as granuloma gluteale infantum is presented. A contributing factor in our patient could be a primary irritant dermatitis or a preexisting candidial infection. The name granuloma gluteale infantum is a misnomer since no granulomas are found in these lesions. ( info) |
3/32. Henna-induced hemolytic anemia and acute renal failure. Henna is a traditional cosmetic agent and is used worldwide, especially in the middle east. Its active agent is lawsone (2-hydroxy-1,4-naphthoquinone). Henna is not only applied to hands or hair as a cosmetic agent in traditional ceremonies, but is also applied to the body on lesions in the treatment of seborrheic dermatitis or fungal infections. However, its application over the body or in newborns is rare. Here we report a 27-day-old boy who developed hemolytic anemia and acute renal failure following topical application of henna to his abdomen, intertriginous region and legs to treat diaper rash.

4/32. "Lucky Luke" contact dermatitis from diapers: a new allergen? "Lucky Luke" contact dermatitis is a particular pattern of diaper dermatitis, reminiscent of a cowboy's gunbelt holsters (1). ( info) |
5/32. Granular parakeratosis: four paediatric cases. Axillary granular parakeratosis (GP) was first described in 1991 as a peculiar eruption presenting with erythematous hyperpigmented and hyperkeratotic papules and plaques of the cutaneous folds frequently associated with pruritus. Histopathology shows a characteristic picture with a conspicuous granular appearance of the parakeratotic horny layer. Until now, only 24 adults, mainly women aged over 40 years, have been reported with GP. We demonstrate that this condition can also occur in young children. Four children aged between 10 and 24 months had asymptomatic hyperpigmented scaling papules 2-3 mm in diameter located on the groin, lower back, buttocks and flanks. In all cases the mothers reported the habit of frequent washing followed by application of many topical products. biopsy revealed the same features in all four patients: the epidermis showed a thickened horny layer with a unique compact parakeratosis with maintenance of the stratum granulosum and marked retention of keratohyaline granules throughout the stratum corneum.

6/32. Infantile granular parakeratosis: recognition of two clinical patterns. Granular parakeratosis is an acquired, idiopathic disorder of keratinization typified by retention hyperkeratosis. It usually occurs in women at intertriginous sites. There have been only 2 reports of infants with granular parakeratosis to our knowledge. We describe 3 additional infants with granular parakeratosis. We demonstrate that infantile granular parakeratosis exhibits 2 clinical patterns: bilateral linear plaques in the inguinal folds; and erythematous geometric plaques underlying pressure points from the diaper. A thick, flakelike scale is present in both forms and is characteristic. Diaper wearing appears to play an important role in the genesis of infantile granular parakeratosis but the mechanisms are unclear. Therapeutic responsiveness to topical agents is ambiguous, however, spontaneous clearance after months to 1 year appears to be the rule. ( info) |
7/32. An infantile cushing syndrome due to misuse of topical steroid. Chronic low-dose exogenous steroid therapy in children can result in hypothalamic-pituitary-adrenal axis dysfunction. However, the development of cushing syndrome from topical steroid therapy is unusual. A 9-month-old girl with a diagnosis of cushing syndrome caused by long-term topical clobetasol propionate application was evaluated. The patient was found to have severe adrenal suppression. Limiting the use of steroid-containing drugs, prescription of less potent agents, especially during infancy, and warning of parents about potential side effects are very important. ( info) |
| Diaper dermatitis is a common problem in outpatient pediatric office settings. Although most diaper rashes represent a form of contact dermatitis in response to irritants in the diaper environment, other rashes may be the result of an allergen in the diaper. On the basis of clinical examination results for 5 patients and patch testing results for 2 patients, we suspect that the patients demonstrated allergic contact dermatitis in response to the various blue, pink, and green dyes in diapers. Although topically administered corticosteroids are useful in the treatment regimen, the preferred treatment for allergic contact dermatitis in the diaper area is the use of dye-free diapers for allergen avoidance. Patch testing may also be valuable in identifying the allergen, because allergen avoidance is the key to prevention of recurrent disease. ( info) |
9/32. Reminder: radiopacities from metal-containing substances. A 17-month-old boy with a toed-out left lower extremity was presented for evaluation. Before coming to the doctor, the mother had applied a zinc oxide lotion to treat a simple diaper rash in the groin. The radiologist did not remove the boy's diaper for the radiographic examination and so did not notice the lotion. The first radiograph showed what looked like multiple soft-tissue calcifications in the groin, but the radiopacities had been produced by the zinc oxide. This case serves as a reminder to be aware that metal-containing substances both on and in the body can produce radiopacities. ( info) |
10/32. Unusual report of diaper rash in a premature infant with group B streptococcal infection. We present the case of a 980-g, female, premature infant with a late-onset maternofetal sepsis, of which the first sign was a diaper-shaped cellulitis. This dermatologic sign in a premature infant is very unusual and needs prompt investigation. Late-onset group B streptococcus infection can be manifested by a cellulitis-adenitis syndrome. ( info) |
