Background: We have described a variant of endemic pemphigus foliaceus (EPF) in El Bagre area known as pemphigus Abreu-Manu. Our previous study suggested that Colombian EPF seemed to react with various plakin family proteins, such as desmoplakins, envoplakin, periplakin BP230, MYZAP, ARVCF, p0071 as well as desmoglein 1.
Objectives: To explore whether patients affected by a new variant of endemic pemphigus foliaceus (El Bagre-EPF) demonstrated oral involvement. Read More

Background: Subcorneal pustular dermatosis, also known as Sneddon-Wilkinson disease, can be classified as one of the neutrophilic dermatoses together with pyoderma gangrenosum. The development of both SPD and PG in the same patient has rarely been reported and may be a strong indicator of IgA dysglobulinemia.

Remarkable effects of anti-IL-17A and anti-IL-23 antibodies on psoriasis indicate deep involvement of IL-23/Th17 axis in the pathogenesis of psoriasis. According to the current immune theory, activation of dendritic cells initiates the generation of this axis. However, this theory is not enough to explain the mechanism, because the process of this activation is obscure and the antigen that is recognized by antigen-presenting cells and pathogenic T cells has long been unidentified.

Subcorneal pustular dermatosis (SPD) or Sneddon-Wilkinson disease is a rare, benign, chronic, sterile pustular eruption which is associated with various systemic diseases including immunoglobinopathies, neoplasms, and autoimmune disorders. This paper reports a case of SPD in a patient with diffuse scleroderma in a 37-year-old woman. The hypothesis that immune dysregulation may play a role in the pathogenesis of SPD was supposed by the coexistence of diffuse scleroderma and SPD in our patient. Read More

The neutrophilic dermatoses (NDs) comprise a group of heterogeneous disorders characterized by inflammatory skin lesions that histologically show an intense inflammatory infiltrate composed primarily by neutrophils, with no evidence of infection or vasculitis. Although there are distinct clinical differences in the classical lesions of these disorders, many patients have overlapping features. In this review, we describe the clinical aspects of the main NDs, including: Sweet Syndrome, ND of the dorsal hands, pyoderma gangrenosum, erythema elevatum diutinum, subcorneal pustular dermatosis, neutrophilic eccrine hidradenitis, rheumatoid neutrophilic dermatitis, neutrophilic panniculitis, and aseptic abscesses including their association with underlying diseases and the differential diagnoses.

Neutrophilic dermatoses are a group of inflammatory skin disorders characterized by an overactive innate immune system with dysregulation of neutrophils without underlying infectious etiology. The major representative conditions discussed are Sweet syndrome; pyoderma gangrenosum; neutrophilic eccrine hidradenitis; palmoplantar eccrine hidradenitis; subcorneal pustular dermatoses; bowel-associated dermatosis arthritis syndrome; and synovitis, acne, pustulosis, hyperostosis, and osteitis. We will also discuss other neutrophilic conditions present almost exclusively in the pediatric population, including congenital erosive and vesicular dermatosis with reticulated supple scarring and the recently described group of autoinflammatory diseases.

Introduction: Neutrophilic dermatoses are a heterogenous group of chronic, cutaneous inflammatory conditions characterized by the accumulation of neutrophils in the skin and by systemic inflammation. Neutrophilic dermatoses can be idiopathic or associated with other inflammatory or systemic diseases, including the group of the hereditary, autoinflammatory syndromes. Clinical management is challenging, due to limited clinical evidence and lack of clinical practice guidelines. Read More

Intra- and subcorneal hematoma, a skin alteration seen palmar and plantar after trauma or physical exercise, can be challenging to distinguish from in situ or invasive acral lentiginous melanoma. Thus, careful examination including dermoscopic and histologic assessment may be necessary to make the correct diagnosis.

Subcorneal pustular dermatosis (SCPD, Sneddon-Wilkinson disease) is a rare chronic-relapsing skin disorder that typically manifests as flaccid sterile pustules without systemic symptoms. Although the accumulation of neutrophils is acknowledged to be a hallmark of SCPD, its exact pathomechanism is still not known. Several chemotactic factors have been implicated in neutrophil recruitment and invasion, including the proinflammatory cytokine TNF-α. Read More

A man aged 56 years with a history of ulcerative colitis (UC) status postsubtotal colectomy was hospitalised with fevers, dry cough, eye redness and a new bloody, mucoid rectal discharge. 2 months prior to admission, the dermatologist had started him on dapsone for subcorneal pustular dermatosis but did not recognise that he had recently self-discontinued mesalamine enemas, inducing a flare of his UC. After a thorough inpatient evaluation, including flexible sigmoidoscopy, active UC involving the rectal stump was determined to be driving his dermatological and ophthalmological findings. Read More

The list of extrapulmonary manifestations due to Mycoplasma pneumoniae infection can be classified according to the following three possible mechanisms derived from the established biological activity of M. pneumoniae; (1) a direct type in which the bacterium is present at the site of inflammation and local inflammatory cytokines induced by the bacterium play an important role (2) an indirect type in which the bacterium is not present at the site of inflammation and immune modulations, such as autoimmunity or formation of immune complexes, play an important role, and (3) a vascular occlusion type in which obstruction of blood flow induced either directly or indirectly by the bacterium plays an important role. Recent studies concerning extrapulmonary manifestations have prompted the author to upgrade the list, including cardiac and aortic thrombi as cardiovascular manifestations; erythema nodosum, cutaneous leukocytoclastic vasculitis, and subcorneal pustular dermatosis as dermatological manifestations; acute cerebellar ataxia, opsoclonus-myoclonus syndrome, and thalamic necrosis as neurological manifestations; pulmonary embolism as a respiratory system manifestation; and renal artery embolism as a urogenital tract manifestation.
