Guía clínica chilena para el estudio y tratamiento de hidradenitis supurativa. Resumen ejecutivo

Hidradenitis suppurativa is a chronic inflammatory disease of the hair follicle characterized by recurrent painful and inflamed lesions, predominantly affecting intertriginous regions. Due to its physical sequelae and impact on quality of life, we should be familiarized with this disease to make an appropriate diagnosis and implement an early treatment. This executive summary of the clinical guideline, elaborated by the hidradenitis suppurativa workgroup of the Chilean Society of Dermatology and Venereology (SOCHIDERM), reviews its definition, epidemiology, pathophysiology, risk factors, comorbidities, psycho-emotional impact, clinical presentation, diagnosis, classifications, ultrasonographic evaluation, and its medical and surgical treatments. Finally, a therapeutic approach algorithm is proposed.

Taxane-induced scleroderma: report of two cases / Esclerodermia inducida por taxanos: informe de dos casos

ABSTRACT Taxanes are a class of chemotherapeutic agents with common associated dermatologic adverse events, such as skin hyperpigmentation, hand-foot skin syndrome, paronychia and onycholysis. Taxane-induced scleroderma is rare. Few cases with skin findings resembling systemic sclerosis, have been reported after the administration of these agents. We report two cases with stage IV breast cancer, aged 66 and 71 years, who developed sclerodermic skin lesions in their extremities after starting treatment with placlitaxel and nabplaclitaxel respectively.

Los taxanos son agentes quimioterapéuticos cuyo uso se asocia a problemas dermatológicos tales como hiperpigmentación, síndrome manos-pies, paroniquia y onicolisis. La esclerodermia inducida por taxanos es rara, con pocos casos informados en la literatura. Informamos los casos de dos pacientes con cáncer de mama en estado IV, de 66 y 71 años, que desarrollaron lesiones esclerodérmicas en las extremidades después de ser tratadas con placlitaxel y nabplaclitaxel, respectivamente.

Guía clínica chilena para el manejo de hidradenitis supurativa / Chilean clinical guidelines for the management of hidradenitis suppurativa

La hidradenitis supurativa es una enfermedad inflamatoria crónica del folículo piloso que se caracteriza por la aparición recurrente de lesiones inflamatorias dolorosas y profundas predominantemente en pliegues. Debido a sus secuelas físicas y en la calidad de vida, debemos estar familiarizados con esta enfermedad, a fin de poder realizar un diagnóstico oportuno e implementar un tratamiento precoz. Esta guía clínica, elaborada por el grupo de trabajo de hidradenitis supurativa de la Sociedad Chilena de Dermatología y Venereología (SOCHIDERM), revisa su definición, epidemiología, fisiopatogenia, factores de riesgo, comorbilidades, impacto psicoemocional, presentación clínica, diagnóstico, clasificaciones, evaluación ecográfica, y tratamientos médico y quirúrgico. Finalmente se propone un algoritmo de enfrentamiento terapéutico.

Eosinophilic annular erythema in childhood - Case report

Abstract: Eosinophilic annular erythema is a rare, benign, recurrent disease, clinically characterized by persistent, annular, erythematous lesions, revealing histopathologically perivascular infiltrates with abundant eosinophils. This report describes an unusual case of eosinophilic annular erythema in a 3-year-old female, requiring sustained doses of hydroxychloroquine to be adequately controlled.

Rheumatoid arthritis and pseudo-vesicular skin plaques: rheumatoid neutrophilic dermatosis

Abstract: A 54 year-old woman with a 3-year history of rheumatoid arthritis (RA) consulted us because of weight loss, fever and skin eruption. On physical examination, erythematous plaques with a pseudo-vesicular appearance were seen on the back of both shoulders. Histological examination was consistent with rheumatoid neutrophilic dermatosis (RND). After 3 days of prednisone treatment, the skin eruption resolved. RND is a rare cutaneous manifestation of seropositive RA, characterized by asymptomatic, symmetrical erythematous plaques with a pseudo-vesicular appearance. Histology characteristically reveals a dense, neutrophilic infiltrate with leucocitoclasis but without other signs of vasculitis. Lesions may resolve spontaneously or with RA treatment. This case illustrates an uncommon skin manifestation of active rheumatoid arthritis.

Erosive lichen planus: a therapeutic challenge

Abstract Erosive lichen planus is an uncommon variant of lichen planus. Chronic erosions of the soles, accompanied by intense and disabling pain, are some of its most characteristic manifestations. We present the case of a woman who developed oral and plantar erosive lichen planus associated with lichen planus pigmentosus and ungueal lichen planus that were diagnosed after several years. The patient failed to respond to multiple therapies requiring longstanding medication but remained refractory. Knowledge of the treatment options for erosive lichen planus is insufficient. Further research is required to clarify their effectiveness, ideally adopting an evidence-based methodology.

Angiomatosis bacilar por Bartonella quintana como primera manifestación de infección por VIH: Report of one case / Bacillary angiomatosis

Background: Bacillary angiomatosis is an unusual infectious disease, with angioproliferative lesions, typical of immunocompromised patients. It is caused by Bartonella quintana and Bartonella henselae, two infectious agents of the genus Bartonella, which trigger variable clinical manifestations, including cutaneous vascular and purpuric lesions, and regional lymphadenopathy, and even a systemic disease with visceral involvement. We report a 38-year-old HIV positive male presenting with a history of six months of cutaneous growing purple angiomatous lesions, located also in nasal fossae, rhi-nopharynx and larynx. The skin biopsy was compatible with bacillary angiomatosis. Polymerase chain reaction of a tissue sample showed homology with B. quintana strain Toulouse. The patient was treated with azithromycin and ciprofloxacin with a favorable evolution.
