pityriasis lichenoides/erythema

Febrile ulceronecrotic Mucha-Habermann disease is a very rare and severe variant of pityriasis lichenoides et varioliformis acuta. Adult cases are difficult to diagnose as in the early course they can mimic erythema multiforme or lymphomatoid papulosis. We report a case of a 38-year-old woman who

Pityriasis lichenoides et varioliformis acuta (PLEVA) is commonly thought of as a disease of young adults, yet we identified five cases, involving patients who were 3, 5, 6, 8, and 11 years of age, among 13,000 consecutive specimens submitted to a general dermatopathology laboratory during a 15-week

The human parvovirus B19 is a small single-strand DNA virus with specific tropism for the membranous receptor P expressed on erythrocytes and endothelial cells. About 60 - 70 % of the adult population is parvovirus B19 seropositive. The contamination usually occurs through droplets from the

It has been shown in previous studies that fibrinoid necrosis not only occurs in connective tissue and in vessel walls, but can also be observed in the liver cells under special conditions and can also be provoked experimentally. It was observed in the present study that certain dermatoses (cases of

AR can be regarded as the most severe variant of the spectrum of chronic actinic dermatitis. The exact etiology is still unknown, but is probably multifactorial, involving contact allergic, photoallergenic, phototoxic, immunologic, and metabolic factors. A diagnosis of AR should only be made when

BACKGROUND Phototherapy is effective for many dermatoses in adults, but there is a paucity of data for its use in children. OBJECTIVE To review the efficacy and tolerability of narrowband UVB phototherapy in children at a tertiary centre in New Zealand, and determine if there were any factors that

The aim of this prospective study in a phototherapy unit was to describe adverse events (AEs) associated with discontinuation of phototherapy in a clinical setting. A total of 872 included patients received 1,256 courses of phototherapy treatment: 76.9% narrow-band UVB (NBUVB); 9.6% systemic

Phototherapy is used for the medical care of cutaneous conditions that do not respond to topical or systemic medical agents, and for conditions that require broad exposure to UV as a stabilizing agent for disease. Numerous wavelengths and delivery devices of ultraviolet light are used in childhood.

Interface dermatitis includes diseases in which the primary pathology involves the dermo-epidermal junction. The salient histological findings include basal cell vacuolization, apoptotic keratinocytes (colloid or Civatte bodies), and obscuring of the dermo-epidermal junction by inflammatory cells.

BACKGROUND Certain dermatologic conditions are known to show seasonal variations in frequency, the reasons for which are unclear but in some cases may be attributable to changes in ambient weather conditions. OBJECTIVE The current study was conducted to determine whether seasonal trends might exist

BACKGROUND Ultraviolet phototherapies are important treatment modalities for a wide range of dermatological conditions. We aim to describe the utilization of phototherapy in the Department of Dermatology Hospital Kuala Lumpur. METHODS This is a 5-year retrospective audit on patients who underwent

Deposition of immunoglobulins, complement and fibrinogen on eosinophilic staining cells was investigated using direct immunofluorescence techniques. Serum factor deposition was detected on benign epidermal eosinophilic cells seen in pityriasis lichenoides et varioliformis acuta, sunburn erythema

BACKGROUND Maculopapular or urticarial eruptions and erythema multiforme sometimes occur in patients affected with Mycoplasma pneumoniae respiratory infections. Further eruptions have also been reported. OBJECTIVE To review the literature addressing M. pneumoniae respiratory infection and rather
