BACKGROUND: Olmsted syndrome (OS) is a congenital dermatosis characterized by palmoplantar keratoderma and periorificial keratotic plaque. TRPV3 (transient receptor potential vanilloid subtype 3) encodes a thermosensitive Ca(2+) channel and is the causative gene of OS. However, the molecular mechanism that causes the pathological development of OS is unclear. OBJECTIVE: We aimed to investigate the molecular mechanisms underlying OS pathology from the perspective of lipid metabolism...

Eosinophilic pustular folliculitis (EPF) or Ofuji disease is a rare dermatosis, prone to recurrence and chronicity. The peak incidence occurs in the third decade of life and its exact etiology remains unknown. Evidence suggests that the expression of adhesion molecules and the production of cytokines activate the follicular unit, but the stimulus that triggers these changes remains unclear. The three clinical variants reported in the literature include classic EPF, immunosuppression-associated EPF, and infancy-associated EPF...

A rare eosinophilic dermatosis, Wells syndrome, also referred to as eosinophilic cellulitis, is characterized by great clinical variability. Typical findings include infiltrated erythematous plaques arising on the extremities. Lesions initially resemble erysipelas/cellulitis, however, they do not improve with antibiotic treatment. Eosinophilic cellulitis is a diagnosis of exclusion that may only be made over the course of the disease, taking into account clinical and characteristic histological findings (flame figures)...

Hepatitis B virus (HBV) infection in pregnant women is very rare in western countries, thus, cutaneous manifestation of HBV infection may be confused with a dermatosis specific of pregnancy. We report a 39-year-old woman who presented in her 20th week of pregnancy with a pruritic rash, which consisted of generalized erythematous plaques, some of them with a purple centre. Serology testing showed acute HBV infection, and a biopsy revealed a superficial and interstitial perivascular inflammatory infiltrate of lymphocytes and eosinophils...

Elastosis perfurans serpiginosa is a rare perforating dermatosis found primarily in adolescents and young adults, characterized by transepidermal elimination of abnormal elastic fibers. The only drug known capable of inducing elastosis perfurans serpiginosa is D-penicillamine. We report the case of a 52 year-old woman with keratotic papules arranged in an annular pattern with central clearing and centrifugal growth, located in the anterior cervical region. The patient was chronically treated with D-penicillamine for Wilson disease...

Granuloma faciale is an eosinophilic dermatosis that typically presents as red-brown facial plaques of middle-aged Caucasian men, while eosinophilic angiocentric fibrosis is a histologically similar fibrotic condition affecting the respiratory mucosa. Both are very uncommon conditions and pose a therapeutic challenge. While a handful of reports have reported concurrent presentation, the authors present the first case of eyelid granuloma faciale with eosinophlilic angiocentric fibrosis.

The presence of eosinophils within the neutrophilic infiltrates of acute febrile neutrophilic dermatosis (Sweet syndrome) is documented in the literature. Here, the authors describe a case of eosinophil-rich acute febrile neutrophilic dermatosis in the setting of new onset enteropathy-associated T-cell lymphoma (EATL), type 1. Histopathologic evaluation of the skin biopsies demonstrated a mixed superficial perivascular and inflammatory infiltrate composed of neutrophils, lymphocytes, and abundant eosinophils...

Juvenile colloid milium is an extremely rare degenerative dermatosis of the dermal connective tissue manifesting before puberty. This chronic skin condition, detected primarily in sun-exposed areas, is clinically characterized by the development of translucent, yellowish papules and plaques containing gelatinous material and by the presence of eosinophilic, fissured material in the papillary dermis. We present two cases of juvenile colloid milium, in a 13-year-old girl and her 10-year-old brother; the condition emerged in both at approximately 6 years of age and progressively worsened...

Eosinophilic pustular folliculitis (EPF) is a sterile inflammatory dermatosis of unknown etiology. In addition to classic EPF, which affects otherwise healthy individuals, an immunocompromised state can cause immunosuppression-associated EPF (IS-EPF), which may be referred to dermatologists in inpatient services for assessments. Infancy-associated EPF (I-EPF) is the least characterized subtype, being observed mainly in non-Japanese infants. Diagnosis of EPF is challenging because its lesions mimic those of other common diseases, such as acne and dermatomycosis...

Eosinophilic dermatosis of hematologic malignancy is a rare, paraneoplastic phenomenon that presents as a pruritic papular or vesicular eruption that is clinically and histopathologically similar to insect bites. We present a 56-year-old man with multiple relapses of diffuse large B cell lymphoma with a typical presentation of pruritic papules and vesicles on the extremities that correlate with a recent relapse of his lymphoma.

Eosinophilic pustular folliculitis (EPF) is a non-infectious inflammatory dermatosis of unknown etiology that principally affects the hair follicles. There are three variants of EPF: (i) classic EPF; (ii) immunosuppression-associated EPF, which is subdivided into HIV-associated (IS/HIV) and non-HIV-associated (IS/non-HIV); and (iii) infancy-associated EPF. Oral indomethacin is efficacious, especially for classic EPF. No comprehensive information on the efficacies of other medical management regimens is currently available...

Nonepisodic angioedema with eosinophilia (NEAE) is a rare condition characterized with monoepisodic angioedema, a nonfebrile state, eosinophilia, normal serum IgM levels, and lack of internal organ involvement. The histology of this disease is not yet well known. The purpose of this study was to characterize the histopathologic features of NEAE. Twelve cases of clinically confirmed NEAE were retrieved from 6 institutions, and these cases were reviewed regarding the clinical data and histopathology, particularly regarding granulomatous lesions...

Granuloma faciale is a rare dermatosis of chronic course, benign, usually asymptomatic, first described in 1945 by Wingley. It is characterized by the appearance of well-defined, single or multiple papules, plaques and nodules, predominantly located in sun-exposed areas, especially the face. In this work we report the case of a female patient, 58 years old, evolving for ten years with multiple erythematous-brownish and asymptomatic papules on the face, whose histological examination confirmed the diagnosis of granuloma faciale...

We report a case of a healthy 26-year-old male with multiple asymptomatic reddish papules and papule-nodules on the central area of the face, persisting from more than 2 months and gradually increasing in number. An incisional skin biopsy revealed a confluent dense granulomatous infiltrate centred by large areas of eosinophilic necrosis consistent with the diagnosis of lupus miliaris disseminatus faciei. This is a rare dermatosis first described in 1878 by Fox, that often poses a clinical challenge as it is a disease process which is difficult to diagnose...

Wells' syndrome (WS), or eosinophilic cellulitis, is an uncommon inflammatory dermatosis of unknown etiology that typically presents with pruritic cellulitis-like plaques on the extremities. Therefore, WS is often misdiagnosed as bacterial cellulitis due to its similarity in presentation. Here, we report two cases of WS that masqueraded as bacterial facial cellulitis. Under treatment with oral prednisone and/or a combination therapy with levocetirizine and hydroxyzine, both patients showed a dramatic improvement of the skin lesions...

Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome is a newly characterized autoinflammatory disorder, caused by mutations in PSMB8. It is characterized by early-onset fevers, accompanied by a widespread, violaceous, and often annular cutaneous eruption. Although the exact pathogenesis of this syndrome is still obscure, it is postulated that the inflammatory disease manifestations stem from excess secretion of interferons. Based on preliminary blood cytokine and gene expression studies, the signature seems to come mostly from type I interferons, which are proposed to lead to the recruitment of immature myeloid cells into the dermis and subcutis...

Darier disease, also known as Darier-White disease, is characterized by yellow to brown, oily keratotic papules and plaques in the seborrheic areas of the face and chest. This disorder may show different clinical manifestations, such as palmoplantar pits and nail abnormalities. The trigger factors are mechanical trauma, heat, humidity, ultraviolet B, and pyogenic infections. The disease usually becomes apparent in the second decade of life. The ATP2 A2 (SERCA2) gene mutation was detected in all patients. Histopathologic changes include epidermal adhesion loss, acantholysis, abnormal keratinization, eosinophilic dyskeratotic cells in the spinous layer known as corps ronds, and the presence of grains in the stratum corneum...
