ABSTRACT

BACKGROUND: Neutrophilic eccrine hidradenitis (NEH) is a benign neutrophilic dermatosis not well recognized beyond an association with malignancy. Although the disease is commonly reported in adults with malignancy, this association is uncommon in children. The diagnosis of NEH is predominantly based on histologic findings to exclude alternative diagnoses for adults, but biopsy is not usually required for children. METHODS: A retrospective study was performed of adult and pediatric patients diagnosed with NEH at three Mayo Clinic sites from January 1, 1992, to January 1, 2022. The aim of this study was to elucidate risk factors for NEH and its clinical characteristics, treatment options, and natural course. Clinical information and pathologic results were collected from health records. Available pathologic slides were reviewed with a dermatopathologist. RESULTS: Of 47 patients identified, 33 had either histologic or clinical confirmation of the diagnosis; 21 were adults (64%), and 12 were children (36%). Most adults (16/21; 76%) had underlying malignancy and received chemotherapy. Five adults (24%) were classified as having idiopathic NEH, and they were younger and had higher NEH recurrence rates than the other adults. Only one pediatric patient (8%) had underlying malignancy. For 10 children (83%), NEH was preceded by strenuous activity. Initial findings of idiopathic NEH were palmoplantar eruptions for both adult and pediatric patients, whereas malignancy-associated NEH commonly involved the face and axillae. CONCLUSIONS: Among adults, NEH is commonly associated with malignancy and chemotherapy. Among children, idiopathic NEH occurs primarily after overexertion, and malignancy is highly unlikely to be the cause of NEH.

ABSTRACT

Neutrophilic eccrine hidradenitis (NEH) is a rare neutrophilic dermatosis involving the eccrine glands. It is commonly associated with haematological malignancy and administration of chemotherapy. An infective aetiology for NEH is termed infectious eccrine hidradenitis (IEH). Pathogens that have been associated with IEH include Nocardia, Serratia, Enterobacter sp., Staphylococcus aureus and Mycobacterium chelonae We describe a case of IEH in a patient with prolonged use of a compression sleeve for their upper limb lymphoedema. The histopathological findings of NEH and IEH are almost identical. Skin tissue culture and rapid clinical improvement with antibiotic therapy are keys in delineating the two subtypes.

ABSTRACT

relación entre esta vitamina y algunas dermatosis ha supuesto la publicación de múltiples trabajos al respecto. Como dermatólogos, conocer sus principales fuentes, síntesis, niveles plasmáticos y algunos de los factores modificadores son varios de los aspectos a recordar. Asimismo, es preciso resaltar los últimos descubrimientos sobre el papel de la vitamina D en las diferentes enfermedades dermatológicas, como el lupus eritematoso, la ictiosis, la dermatitis atópica, la hidrosadenitis supurativa, el acné, la alopecia areata y androgenética, el melanoma y el cáncer cutáneo no melanoma, así como la relevancia como terapia adyuvante en pacientes en tratamiento crónico con corticoides. Acercamos al lector la información más relevante y reciente de la relación entre la vitamina D y las enfermedades de la piel, así como la importancia de conocer los niveles de esta vitamina


In recent years, the growing interest in the role played by vitamin D in skin disease has given rise to the publication of many studies of the relationship between this vitamin and certain skin conditions. As dermatologists, we need to understand, among other aspects, how vitamin D is synthesized and the main sources in humans, as well as plasma levels and the factors that can modify them. Of particular interest are the latest discoveries about the role of vitamin D in skin diseases such as lupus erythematosus, ichthyosis, atopic dermatitis, hidradenitis suppurativa, acne, alopecia areata, androgenetic alopecia, melanoma, and nonmelanoma skin cancer. Also of interest is the importance of vitamin D as adjuvant therapy in patients on long-term treatment with corticosteroids. In this review, we provide an overview of the most important and most recent information regarding the relationship between vitamin D and skin disease and discuss the importance of assessing individual vitamin D status and correcting deficiencies

ABSTRACT

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. The clinical characteristics, diagnostic approach, and treatment management in the pediatric and adult population are discussed.

ABSTRACT

Inflammatory bowel disease (IBD) could be associated with several extra-intestinal manifestations (EIMs) involving musculoskeletal, hepatopancreatobiliary, ocular, renal, and pulmonary systems, as well as the skin. In the last years, hidradenitis suppurativa (HS) is acquiring an increasing interest. IBD, especially Crohn's disease (CD), is among the most reported associated diseases in HS patients. The aim of this paper is to give a brief overview of data showing a possible epidemiologic and pathogenetic association between IBD and HS. We performed a pooled-data analysis of four studies and pooled prevalence of HS in IBD patients was 12.8%, with a 95%CI of 11.7%-13.9%. HS was present in 17.3% of subjects with CD (95%CI: 15.5%-19.1%) and in 8.5% of UC patients (95%CI: 7.0%-9.9%). Some items, especially altered immune imbalance, are generally involved in IBD pathogenesis as well as invoked by HS. Smoking is one of the most relevant risk factors for both disorders, representing a predictor of their severity, despite, actually, there being a lack of studies analyzing a possible shared pathway. A role for inheritance in HS and CD pathogenesis has been supposed. Despite a genetic susceptibility having been demonstrated for both diseases, further studies are needed to investigate a genetic mutual route. Although the pathogenesis of IBD and HS is generally linked to alterations of the immune response, recent findings suggest a role for intestinal and skin microbiota, respectively. In detail, the frequent finding of Staphylococcus aureus and coagulase-negative staphylococci on HS cutaneous lesions suggests a bacterial involvement in disease pathogenesis. Moreover, microflora varies in the different cutaneous regions of the body and, consequently, two different profiles of HS patients have been identified on these bases. On the other hand, it is well-known that intestinal microbiota may be considered as "the explosive mixture" at the origin of IBD despite the exact relationship having not been completely clarified yet. A better comprehension of the role that some bacterial species play in the IBD pathogenesis may be essential to develop appropriate management strategies in the near future. A final point is represented by some similarities in the therapeutic management of HS and IBD, since they may be controlled by immunomodulatory drugs. In conclusion, an unregulated inflammation may cause the lesions typical of both HS and IBD, particularly when they coexist. However, this is still a largely unexplored field.

ABSTRACT

BACKGROUND: Hidradenitis is a disorder where abscesses appear after the infection of the apocrine sweat glands. It is located normally in the axillae, groin, perineal region, and the scalp. CLINICAL CASE: A 37 year old male was referred by his GP to the General Surgery Department with axillary hidradenitis which had evolved over the years. The physical examination shows signs of hidradenitis in both axillae, with a noticeable suppurative hidradenitis in the right armpit. En bloc extirpation was performed to remove the whole affected area. The pathological examination revealed a cutaneous leishmaniasis. Subsequently, fucidin was administered topically, as well as local infiltrations of one millilitre of Glucantime™. DISCUSSION: Hidradenitis normally appears in intertriginous areas and its manifestation is accompanied by recurrent subcutaneous nodules. The incidence rate in females is three times higher than in males. The isolated Hidradenitis caused by Leishmania is a rare condition presented only in endemic areas or in immunocompromised patients, such as HIV-infected patients. Clinical manifestations can be different and the diagnosis can be confirmed through haematoxylin-eosin. The main pattern displays a disorganised granuloma without necrosis. Systemic or topical treatment can be applied. Immunotherapy treatment is the most common. CONCLUSIONS: Hidradenitis caused by Leishmania in HIV-negative patients is a rare condition. Therefore it is important to perform a good histological diagnosis and to administer the right treatment.

ABSTRACT

We report a case of acquired generalized anhidrosis successfully treated with cyclosporine. A skin biopsy showed T cell infiltration around the sweat glands and labial biopsy revealed lymphoplasmacytic infiltration around the minor salivary gland, suggesting an underlying autoimmune disease such as Sjögren's syndrome. Administration of cyclosporine markedly improved the patient's condition and sympathetic skin response; thus cyclosporine may be effective for treating anhidrosis in patients with autoimmune disorders.

ABSTRACT

El dispositivo intrauterino (DIU) de levonorgestrel (LNG) es un método anticonceptivo de solo gestágeno de larga duración. Su acción se ejerce a nivel local pero a veces se asocia a manifestaciones sistémicas por el efecto androgénico del LNG. Presentamos el caso de una paciente que desarrolló un cuadro de hidrosadenitis supurativa después de la inserción del DIU de LNG y que mejoró tras su retirada. Los dermatólogos deben preguntar acerca del uso de métodos anticonceptivos que lleven LNG en mujeres que cursan con esta enfermedad cutánea(AU)


The levonorgestrel (LNG)-releasing intrauterine device (IUD) is a long-acting, progestin-only contraceptive method. The effect of this method is mainly local but systemic side effects sometimes occur because of the androgenic activity of LNG. We report the case of a woman who developed hidrosadenitis suppurativa after insertion of an LNG-IUD, which was resolved by removal of the device. Dermatologists should inquire about the use of LNG as a contraceptive method in women with this cutaneous disease(AU)

ABSTRACT

Contexto: A hidrosadenite é uma doença cutânea crônica e recorrente, com prevalência estimada de 1% e mais comum no sexo feminino. Apesar de se tratar de entidade há muito tempo conhecida, a dificuldade terapêutica ainda é uma realidade. Relato de caso: Apresenta-se um caso de hidrosadenite em paciente de 49 anos envolvendo os grandes lábios bilateralmente, a qual foi submetida à exérese ampla com fechamento por primeira intenção, obtendo-se excelente resultado terapêutico e estético. Discussão: A hidrosadenite é causa de grande transtorno psicológico e social, com prejuízo na qualidade de vida. As possibilidades terapêuticas variam desde antibióticos tópicos e sistêmicos, medicamentos com ação antiandrogênica, retinoides sistêmicos, imunossupressores e, mais recentemente, os antagonistas do fator de necrose tumoral, o uso de tecnologias como o laser e a terapia fotodinâmica até drenagens intermitentes, exéreses parciais e cirurgia radical. A abordagem cirúrgica ampla com margens, associada à cicatrização por segunda intenção, é a preferida de vários autores, porém, o fechamento primário pode estar indicado em casos selecionados.Conclusões: Apesar dos diversos estudos, ainda não existem tratamentos padronizados e com resposta clínica previsível. Cabe ao médico conseguir individualizar cada paciente na busca do melhor tratamento, baseando-se nas evidências existentes até hoje na literatura.

ABSTRACT

Introducción. La hidrosadenitis supurativa es una enfermedad inflamatoria crónica, que cursa en brotes, con lesiones dolorosas, fístulas y cicatrices en axilas, ingles, glúteos, región perianal e inframamaria. Entre los múltiples tratamientos farmacológicos disponibles, en los últimos cinco años se ha demostrado la eficacia del infliximab, un tratamiento habitualmente utilizado en dermatología para el control de la psoriasis. Pacientes y método. Estudio prospectivo, observacional, realizado con el objetivo de determinar la eficacia y seguridad del infliximab en el tratamiento de la hidrosadenitis supurativa. Tres pacientes mujeres con hidrosadenitis supurativa de más de 10 años de evolución, con afectación de al menos dos localizaciones anatómicas y resistente a terapias convencionales. Se realiza tratamiento con infliximab a cada una de las pacientes en dosis de 5 mg/kg/infusión en las semanas 0, 2, 6 y posteriormente cada 8 semanas. Resultados. Dos de las tres pacientes presentaron una mejoría leve-moderada de su enfermedad, mientras que la tercera paciente no obtuvo mejoría. Podemos destacar la variabilidad de los resultados observada entre las tres pacientes. Los efectos secundarios fueron en general leves y bien tolerados por las tres pacientes. Pese a ello, dos de las pacientes tuvieron que suspender el tratamiento debido a la falta de eficacia del mismo en uno de los casos y a un cuadro de artralgias generalizadas en otro. Conclusiones. El tratamiento de la hidrosadenitis supurativa con infliximab constituye una alternativa moderadamente útil en algunos casos


Introduction. Hidradenitis suppurativa is a chronic inflammatory disease that runs in outbreaks with painful lesions, fistulas and scars in axillae, groins, buttocks, and perianal and submammary regions. Among multiple drug therapies available, infliximab, usually employed in dermatology to control psoriasis, has shown its efficacy in the past five years. Patients and method. It is a prospective, observational study to determine the efficacy and safety of infliximab in the treatment of hidradenitis suppurativa. We selected three women with a history of hidradenitis suppurativa of more than 10 years, with involvement of at least two anatomic locations that was recalcitrant to conventional therapies. Each patient received infliximab at a dose of 5mg/kg/infusion on weeks 0, 2, 6 and every 8 weeks thereafter. Results. Two of the three patients showed mild to moderate improvement of their disease while the third patient did not improve. We can highlight the variability of the results observed in these three patients. Adverse effects were generally mild and well tolerated by the three patients. Despite this, two patients withdrew the therapy due to loss of efficacy in one case and the development of generalized arthalgias in the other case. Conclusions. Treatment of hidradenitis supurativa with infliximab constitutes a moderately useful alternative in some cases
