Eosinophilic Folliculitis in 2 HIV-Positive Women

Eosinophilic pustular folliculitis (EPF) in a patient with HIV infection

Eosinophilic pustular folliculitis is a chronic, recurrent dermatosis, of unknown etiology, which is histologically characterized by folliculotropic inflammatory infiltrates with admixed eosinophils in the dermis. It has often presented with immunosuppression and especially with HIV-Infection. In the HAART-era, eosinophilic pustular folliculitis has become a rarity. It is often being misdiagnosed as acne vulgaris, rosacea, bacterial folliculitis, dermatomycosis and seborrheic dermatitis. The treatment of this disease may be difficult.

Clinical, Imaging, and Pathologic Features of Conditions with Combined Esophageal and Cutaneous Manifestations

A variety of clinically significant conditions can affect both the esophagus and the skin. Esophageal and cutaneous manifestations may directly reflect the underlying disease process, as in infections such as herpes simplex virus, bullous diseases such as epidermolysis bullosa and mucous membrane pemphigoid, connective tissue diseases such as systemic sclerosis, and inflammatory diseases such as lichen planus. Alternatively, esophageal and cutaneous findings may result from conditions that are closely associated with and potentially pathognomonic for but distinct from the underlying disease process, as in genetic diseases such as Cowden syndrome or paraneoplastic syndromes such as acrokeratosis paraneoplastica. Other diseases such as Crohn disease may have cutaneous manifestations that directly reflect the same underlying inflammatory process that affects the gastrointestinal tract or cutaneous manifestations that represent reactive or associated conditions distinct from the underlying inflammatory process. The cutaneous manifestations of disease may precede, coincide with, or follow the esophageal manifestations of disease. The authors present the characteristic clinical features and imaging findings associated with common and uncommon conditions that have esophageal and cutaneous manifestations. Each condition is presented with a brief overview, discussion of salient clinical and cutaneous manifestations, and description of the typical esophageal imaging findings, with particular attention to implications for diagnosis, prognosis, and treatment. Recognition of potential associations between cutaneous lesions and esophageal imaging findings is important for establishing a specific diagnosis or generating a meaningful differential diagnosis.

Dermatoses neutrofílicas: parte II

Uma breve revisão das dermatoses neutrofílicas em pacientes pediátricos também é realizada.

Eosinophilia is associated with a higher mortality rate among patients with autoimmune lymphoproliferative syndrome

Autoimmune lymphoproliferative syndrome (ALPS) is a disorder associated with heritable defects in lymphocyte apoptosis that result in chronic nonmalignant lymphadenopathy, splenomegaly, and autoimmunity. To examine the prevalence, mechanisms, and potential implications of eosinophilia in ALPS, we reviewed data retrospectively from 187 consecutive ALPS patients and their family members studied at the National Institutes of Health. ALPS patients with eosinophilia were compared with ALPS patients without eosinophilia with respect to their clinical and immunologic phenotype. Potential mechanisms for the eosinophilia, including abnormal Fas-mediated eosinophil apoptosis, increased production of eosinophilopoietic cytokines, and presence of anti-eosinophilic autoantibodies were also explored in a small number of patients from whom samples were available. Analysis of data from 68 ALPS patients and 119 of their relatives identified a distinct subgroup of patients with prominent and persisting eosinophilia that proved to be associated with increased numbers of peripheral blood leukocytes (PBL) of multiple lineages and a trend towards increased serum IgE levels. Eosinophilic ALPS patients also had a significantly higher risk of death due to infectious complications. Although the specific etiology of the eosinophilia in these patients remains uncertain, it does not appear to be associated with an altered serum cytokine profile, increased survival responsiveness of eosinophils to IL-5, defective Fas-mediated eosinophil apoptosis, or anti-eosinophil antibodies. Eosinophilia defines a distinct subgroup of ALPS patients with increased serum IgE levels, increased numbers of PBL of multiple lineages, and higher mortality from infectious complications.

Eosinophilic pustular folliculitis: a 40 year retrospect

Eosinophilic pustular folliculitis (EPF) is a noninfectious eosinophilic infiltration of hair follicles first described 40 years ago. There are 3 variants: classic EPF, immunosuppression-associated (mostly HIV-related), and infancy-associated EPF. EPF has been classified as an AIDS-defining illness. In both children and adults EPF should be viewed as a possible cutaneous sign of immunosuppression. However, it may also be seen in persons with normal immune status. We review EPF on the 40th anniversary of its original description.

Eosinophilic folliculitis in HIV-infected women: case series and review

BACKGROUND AND OBJECTIVE

Dermatologic conditions are often presenting signs of HIV infection and may be the sole cause of morbidity in patients who have otherwise stable HIV disease. Eosinophilic folliculitis is a pruritic, follicular eruption that typically manifests late in the course of HIV infection. Most published reports of eosinophilic folliculitis have been in HIV-infected men. In those reports, a characteristic truncal distribution was present, with involvement of the head, neck, and upper extremities commonly seen as well. The objective of this study was to better characterize the presentation of eosinophilic folliculitis in women.

METHODS

We conducted a retrospective chart review of six HIV-seropositive women with eosinophilic folliculitis previously seen in our dermatology clinics. We also reviewed the literature for cases of eosinophilic folliculitis in women and for clinical and therapeutic aspects of the condition, particularly in women.

RESULTS

In our case series, we found that eosinophilic folliculitis in women may predominantly affect the face and mimic acne excoriée. A review of the literature of HIV-associated eosinophilic folliculitis in women supports these findings. Regarding treatment, many therapies are available, but none is uniformly effective.

CONCLUSION

Given the dramatic rise in the incidence of HIV infection in women, who now represent nearly 50% of adults living worldwide with HIV/AIDS, a heightened awareness of HIV-related dermatoses in women is essential. HIV-associated eosinophilic folliculitis should be considered in the differential diagnosis of chronic, pruritic, papular facial eruptions in females.
