Erosive papulonodular dermatosis associated with topical benzocaine: a report of two cases and evidence that granuloma gluteale, pseudoverrucous papules, and Jacquet's erosive dermatitis are a disease spectrum.

Granuloma gluteale infantum/adultorum, pseudoverrucous papules, and Jacquet's erosive diaper dermatitis are fairly uncommon manifestations of irritant contact dermatitis historically thought to be distinct clinical entities. Here we report two informative cases of an erosive papulonodular dermatosis in the genital and suprapubic area associated with topical benzocaine. We review granuloma gluteale infantum, pseudoverrucous papules and nodules, and Jacquet's erosive diaper dermatitis, and propose that these disorders may all be variants of genitocrural irritant dermatitis.

Usefulness (or lack thereof) of immunophenotyping in atypical cutaneous T-cell infiltrates.

Our purpose was to evaluate the interobserver concordance for the diagnoses of mycosis fungoides (MF), atypical dermatoses (AD), and benign dermatoses (BD) and the impact of T-cell immunophenotyping on the diagnoses MF, AD, and BD. Specimens of MF (n = 57), AD (n = 27), BD and normal skin (n = 54) were reviewed by 2 hematopathologists and 1 dermatopathologist to establish diagnostic interobserver concordance by routine morphologic examination. Immunophenotyping was performed to evaluate expression of CD2, CD3, CD4, CD5, CD7, CD8, CD20, CD30, and MIB-1. The interobserver concordance was fair to moderate compared with the original diagnosis. Partial deletion of CD2 alone was associated significantly with MF. Epidermal deletions of 2 or 3 T-cell antigens or 2 T-cell antigens not including CD7 were associated significantly with MF. An elevated CD4/CD8 ratio correlated with MF. Morphologic features were most diagnostic of MF. Immunophenotyping generally resulted in downgrading of the reaction pattern but was helpful in distinguishing MF from benign dermatoses.

An intertrigo-like eruption from pegylated liposomal doxorubicin.

Pegylated liposomal doxorubicin (PLD) is a chemotherapeutic agent used in the treatment of solid tumors. It has a considerably lower risk of cardiotoxicity than its parent compound, doxorubicin. PLD also has a different cutaneous side effect profile than doxorubicin, and its cutaneous toxicity can be dose limiting. We report the case of a 60-year-old woman who developed erythema and erosions in the axilla and groin while on PLD for breast cancer. Nystatin was ineffective. Biopsies revealed an interface dermatitis with epidermal dysmaturation. Bland emollients and reduction in the dose of PLD resulted in resolution of the eruption. An intertriginous eruption with histological features of epidermal dysmaturation and an interface dermatitis has been previously reported in the dermatopathology literature. This eruption appears to be a distinct cutaneous toxicity of PLD.

Relapsing polychondritis.

A 43-year-old Chilean man presented with a 5-month history of progressive hypertrophy of the ears bilaterally. He was seen initially by a dermatologist in Chile for complaints of erythema and swelling of the ears, and had been treated unsuccessfully with topical steroids and antimicrobial ointments. On presentation to our clinic, the hypertrophy had stabilized and the erythema had resolved, but he complained of decreased hearing due to narrowing of the external auditory canal. Associated symptoms included occasional pruritus, but he denied any pain. He also denied a history of sinus problems, respiratory symptoms, ocular pain, chest pain, and arthralgias. Physical examination revealed firm hypertrophy of the collagenous areas of both ears, sparing the ear lobes (Fig. 1). No pain was elicited on palpation. No conjunctivitis was noted and the nasal passages were clear. His chest was clear to auscultation. Histologic examination revealed a minimal perivascular infiltrate of lymphocytes and plasma cells in the dermis with fibrosis of the subcutis (Fig. 2). Blood tests showed a normal complete blood count, antinuclear antibody, and rheumatoid factor. Anti-collagen II antibodies were elevated at 29.2 Eu/ml (normal, 0-20 Eu/ml; borderline, 20-25 Eu/ml; elevated, > 25 Eu/ml).

Treatment of toxic epidermal necrolysis with intravenous immunoglobulin in children.

BACKGROUND: Toxic epidermal necrolysis (TEN) is an acute illness characterized by rapid onset of skin necrosis and high mortality. Standard treatment is primarily aimed at supportive care in a burn unit setting. OBJECTIVE: We evaluated the outcome of 8 pediatric patients treated for TEN with intravenous immunoglobulin (IVIg) over a 3-year period. METHODS: We performed a retrospective analysis of pediatric patients with a diagnosis of TEN between 1999 and 2001, obtained from a computerized database. RESULTS: Mean body surface involvement of 8 patients treated with IVIg was 67%. The average length of hospitalization was 13.6 days, with an average delay in treatment of 3.2 days. The average time to arrest in progression of lesions was 2.1 days and to complete re-epithelialization, 8.1 days. The mortality rate was 0%. The majority of complications were infectious. CONCLUSION: IVIg is a safe and effective treatment for TEN in the pediatric population. Randomized trials are needed to further evaluate the efficacy of IVIg compared with other modalities.

Case reports: treatment of nevirapine-associated dress syndrome with intravenous immune globulin (IVIG).

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is an adverse drug reaction most commonly associated with aromatic antiepileptic agents. It is characterized by the triad of skin eruption, fever, and systemic involvement, with the latter usually manifesting as hepatitis and lymphadenopathy. Mortality is primarily due to hepatic failure and can be as high as 10%. Formerly referred to by names such as Dilantin hypersensitivity syndrome and anticonvulsant hypersensitivity syndrome, DRESS syndrome is a more precise term since this reaction pattern can be seen with other agents. DRESS syndrome has also been reported in association with sulfonamides, allopurinol, terbinafine, minocycline, azathioprine, and dapsone as well as with several antiretroviral agents such as abacavir and nevirapine. We describe a patient with HIV who developed nevirapine hypersensitivity syndrome who was successfully treated with intravenous immune globulin (IVIG).
