Myasis is an ectoparasitic infection caused by human (as well as some domestic and wild animals) tissue and cavity infestation by _Diptera_ larvae, generally flies. This condition is more frequent in tropical areas, and it may also occur in places with deficient sanitary conditions. We present the case of a patient from a tropical area, a farmer who reported exposure to dead animals, wild animals, and flies, in whom forunculoid type cutaneous myasis in the scrotum region was diagnosed, which also had superimposed infection. This patient received therapy with intravenously administered antibacterial agents, a single dose of oral ivermectin. Locally, orifices were occluded with basil. This was followed by the forceps-aided extraction of 20 larvae in two sessions. The patient had good progression. We consider this case is an original contribution, given that genitalia infection by fly larva...

A 77-year-old male, with a history of heart failure and atrial fibrillation receiving warfarin, hypothyroidism, diabetes mellitus and hyperuricaemia, with a one-year history of erythematous and desquamative skin lesions in the trunk, pruritic and moderate recurrent eosinophilia. After allergic, parasitic, autoimmune and neoplastic causes were ruled out, the diagnosis of idiopathic hypereosinophilic syndrome was done. He was treated with prednisone and hydroxyurea, resulting in complete remission of eosinophilia and progressive improvement of dermal lesions.

Varón de 77 años de edad, con antecedentes de insuficiencia cardiaca y fibrilación auricular recibiendo warfarina, hipotiroidismo, diabetes mellitus e hiperuricemia, con historia de un año de lesiones dérmicas eritematosas y descamativas en el tronco, pruriginosas y con moderada eosinofilia recurrente. Después de descartarse causas alérgicas, parasitarias, autoinmunes y neoplásicas, se hizo el diagnóstico de síndrome hipereosinofílico idiopático. Recibió tratamiento con prednisona e hidroxiurea, consiguiéndose una remisión completa de la eosinofilia y mejoría progresiva de las lesiones dérmicas.

Varón de 32 años de edad con lesiones orales y con enfermedad renal crónica (ERC) con requerimiento de hemodiálisis. Al cabo de la séptima sesión de hemodiálisis, y sin tratamiento tópico de la cavidad oral, las lesiones orales remitieron en su totalidad. La estomatitis urémica es una manifestación poco frecuente en la cavidad oral que ocurre en la falla renal crónica no diagnosticada y en la forma terminal. Su etiopatogenia no está del todo aclarada; sin embargo, puede deberse al incremento de los compuestos amoniacales. Su identificación depende de un cuidadoso examen de la cavidad oral en todo paciente urémico.
