RESUMO
Resumen La infección por Strongyloides stercoralis es una parasitosis frecuente en las regiones tropicales y subtropicales, incluyendo la Amazonía peruana. En pacientes con inmunocompromiso, las manifestaciones clínicas son variadas y es frecuente la diseminación sistémica de la enfermedad, con compromiso de diversos órganos. Las manifestaciones cutáneas son infrecuentes y se describen en pacientes con algún grado de inmunosupresión. Se presenta el caso de un paciente inmunocompetente que desarrolló una púrpura reactiva por una infección por Strongyloides stercoralis crónica. Ante ello, es posible el compromiso cutáneo en pacientes inmunocompetentes con reagudización sistémica por este parásito.
Infection with Strongyloides stercoralis is a common parasitic infection in tropical and subtropical regions, including the Peruvian Amazon. The clinical manifestations are varied in patients with immunocompromised disease, and the systemic spread of the disease is frequent, compromising different organs and systems. Cutaneous manifestations are infrequent, being described in patients with some degree of immunosuppression. We present the case of an immunocompetent patient who developed a reactive purpura due to chronic Strongyloides stercoralis infection. Thus, skin involvement is possible in immunocompetent patients with systemic exacerbation due to this parasite.

Abstract: Pigmented purpuric dermatoses (PPD) include a spectrum of diseases with different clinical aspects, but with similar histopathological features. Specific clinical findings allow the division of PPD in variants. Schamberg's disease is the most common. Treatment is sometimes ineffective and recurrences are common. There are reports of patients who responded well to the use of colchicine. We report the case of a 32-year-old woman, previously healthy, with a history of onset of asymptomatic lesions in legs. She presented purpuric skin eruptions and brownish stains diffusely distributed in the lower limbs. Biopsy was compatible with PPD. We decided for the introduction of colchicine, with good clinical response. The patient has been followed on outpatient basis for ten months without recurrence.

Pigmented purpuric dermatoses are chronic and relapsing disorders characterized by a symmetrical rash of petechial and pigmentary macules, mainly confined to the lower limbs. Purpura annularis telangiectodes of Majocchi is a less common variant of Pigmented purpuric dermatoses characterized by punctate telangiectatic macules progressing to annular, hyperpigmented patches with central clearing and infrequent atrophy. A 12 year-old girl presented with asymptomatic round to oval reddish brown macules, present symmetrically over her lower and upper limbs for 3 years. Few lesions were annular in shape. Biopsy from the lesion was compatible with Pigmented purpuric dermatoses. On the basis of clinical and histopathological findings, a diagnosis of Purpura annularis telangiectodes of Majocchi was made. The patient began phototherapy thrice a week and showed excellent response.

La púrpura fulminante (PF), es una enfermedad febril de fatales consecuencias, caracterizada por lesiones equimóticas confluentes, hipotensión arterial y coagulación intravascular diseminada (CID). Se informa el caso de una mujer de 20 años de edad, que desarrolló PF secundaria a un parto séptico. Se resalta la importancia de un diagnóstico precoz, el tratamiento adecuado (que incluya la causa), y el apoyo multidisciplinario
