ABSTRACT
Pyoderma gangrenosum (PD) is a rare, chronic, relapsing, ulcerative, neutrophilic cutaneous disease and may be difficult to recognize. It is not uncommon for PD to be mistakenly diagnosed as vascular occlusive or venous disease, vasculitis, cancer, infection, exogenous tissue injury, or other inflammatory disorders. A 55-year-old woman with a 5-year history of a very painful and enlarging ulcer presented at the authors' clinic. Previously, based on an original diagnosis of venous ulcer, the wound had been surgically debrided and managed with saline-soaked gauze and compression therapy. After the authors secured a complete history (which included rheumatoid arthritis) and assessment, PD was suspected. A biopsy was performed for histological confirmation. Pyoderma gangrenosum treatment, including oral corticosteroids and topical 0.01% tacrolimus twice daily covered with nonadhesive gauze and compression wrapping, was started. After 4 weeks, the wound had improved noticeably and pain medications to manage wound pain were discontinued. The wound was completely healed after 4 months. The presence or absence of PD must be ascertained in all patients who present with a history of painful lower leg ulcers and PD risk factors, such as rheumatoid arthritis.

BACKGROUND: Telemedicine has been used for more than 50 years. Dermatology has been one of the specialties where it has reached great development (Teledermatology). When the observation is made simultaneously by the outreach specialist and by the non-specialist at the workplace, it is called synchronous teledermatology, and asynchronous when information is filmed, stored, and presented to the specialist at a later time. OBJECTIVE: To evaluate efficacy and reliability of asynchronous teledermatology for adequate diagnosis of skin diseases. METHODS: Fifty patients with dermatologic disorders were seen in a poor tropical rural zone, first by non-dermatologists in conventional consultation and then by dermatologists to obtain a diagnosis (gold standard); the latter step consisted of evaluation of filmed lesions by another group of dermatologist later on. RESULTS: There was a high concordance of diagnosis between the two groups of dermatologists when kappa analysis was performed. CONCLUSION: It appears important to use these technological advances in developing-countries to improve delivery of health care.

Introducción: la Telemedicina ha sido utilizada desde hace más de 50 años. Ha tenido auge en Dermatología, fundamentalmente en países desarrollados (Teledermatología). Puede ser sincrónica o asincrónica. Objetivo: evaluar la eficacia y confiabilidad de la aplicación de la tecnología de almacenamiento y repetición de video (teledermatología asincrónica) en el diagnóstico de enfermedades dermatológicas. Métodos: se estudiaron 50 pacientes con problemas cutáneos en una población rural, marginada del área tropical, los cuales primero fueron evaluados por dermatólogos en una consulta tradicional (estándar de oro); posteriormente las lesiones fueron filmadas por un grupo de estudiantes y en un último paso, el videocasete con las lesiones y la historia clínica por escrito fueron proporcionadas a otro grupo de dermatólogos cuyo diagnóstico fue comparado con el del estándar de oro. Resultados: se notó alta concordancia de diagnósticos entre los teledermatólogos y el estándar de oro. Se realizó un análisis estadístico de concordancia kappa el cual fue adecuado para cada uno de los observadores. Conclusiones: este estudio evidencia la eficacia de la teledermatología asincrónica en áreas marginales. Con base en este hallazgo se sugiriere la ampliación de su uso.
