RESUMO

Trichodysplasia spinulosa is a rare disease that occurs in the setting of immunosuppression, associated with tolerogenic therapy used in allograft recipients or patients with hematologic malignancies. Clinically, it is characterized by a centrofacial cutaneous eruption of erythematous papules with a central keratinous spicule, often associated with variable degrees of alopecia. Histologic findings are characteristic, and electron microscopy reveals the presence of trichodysplasia spinulosa associated polyomavirus. We report a 47-year-old woman with idiopathic autoimmune pancytopenia refractory to diverse immunosuppressant regimens, with clinical and pathologic findings compatible with the disease, in whom complementary studies were required to exclude other differential diagnoses.

RESUMO

Resumen La leishmaniasis es una infección producida por protozoos del género Leishmania, transmitida por insectos hematófagos. La forma de presentación más frecuente es la leishmaniasis cutánea (LC), en la cual se observan úlceras crónicas e indoloras, usualmente localizadas en el sitio de la picadura del insecto. El diagnóstico y tratamiento de esta enfermedad son especialmente desafiantes en zonas no endémicas como nuestro país, requiriendo el uso de diversas técnicas de laboratorio y el apoyo de expertos. Se reporta el caso clínico importado de un varón de 42 años con LC causada por L. braziliensis con respuesta exitosa al tratamiento con anfotericina B liposomal.


Leishmaniasis is an infection caused by protozoa of the genus Leishmania sp. and transmitted by sandfly vectors. Cutaneous leishmaniasis (CL) is the most frequent form of presentation. Clinically, chronic and painless ulcers are observed, which usually occur at the site of the sandfly bite. The diagnosis and treatment of this disease is specially challenging in non-endemic countries such as Chile, requiring the use of diverse laboratory techniques as well as the support of expert physicians. Herein we report an imported case of a healthy 42-year-old male with CL caused by L. braziliensis with successful response to liposomal amphotericin B.
