Carcinomas escamosos com miíase, uma nova tendência? / Squamous cell carcinomas with myiasis, a new trend?

Importância do problema: Este artigo se propõe a descrever dois casos de miíase em feridas neoplásicas de carcinomas escamosos, uma associação rara que vem se tornando comum. Comentários: Esta associação deve-se as altas prevalências de HPV, baixas condições socioeconômicas e de higiene, além do manejo inadequado de feridas e do descaso dos homens para com sua saúde, os principais afetados quando o assunto é câncer orofaríngeo e de pênis.(AU)

Relevance: This article intends to describe two cases of myiasis on squamous cells neoplasic wounds, a rare association that are becoming more easily seen nowadays. Comments: This association due to high HPV serum prevalences, low social and hygiene conditions, in addition to the precarious wounds care and men´s health seek relapse, the mainly affected when the issue is oropharynx and penis cancers.

Diagnóstico de helmintiasis por videocápsula endoscópica / Diagnosis of helminthiasis by endoscopic videocapsule

Resumen La helmintiasis corresponde a una parasitosis intestinal altamente prevalente en países en desarrollo, y que viene aumentando en los países desarrollados. Teniendo en cuenta el ciclo de vida de los helmintos, su presentación se relaciona con situaciones ambientales y socioeconómicas de alto riesgo. Por tanto, su presencia endémica puede considerarse un problema de salud pública. Para el diagnóstico, se disponen de varios elementos que incluyen el estudio de la materia fecal, la endoscopia y las imágenes diagnósticas como los estudios de rayos X de vías digestivas, la tomografía axial computarizada (TAC) y la resonancia magnética (RM). En la actualidad, existen reportes de diagnóstico de helmintiasis por cápsula endoscópica que también han permitido el estudio de la ecología y de la patología in situ de estos parásitos. Se presenta un caso clínico de helmintiasis compatible con estrongiloidosis, diagnosticado por cápsula endoscópica por el Grupo de Gastroenterología Clínico-Quirúrgica de la Universidad de Caldas, Colombia.

Abstract Helminthiasis is an intestinal parasitosis that is very prevalent in developing countries but is increasing in developed countries. Taking into account the life cycle of helminths, their presentation is related to high-risk environmental and socioeconomic situations. Endemic presence can be considered a public health problem. Several methods are available for diagnosis including the study of fecal matter, endoscopy and diagnostic imaging such as X-ray studies of the digestive tract, CT scans and magnetic resonance. Recently, there have been reports of diagnosis of helminthiasis by capsule endoscopy which has also allowed the study of the ecology and in situ pathology of these parasites. We present a clinical case of helminthiasis compatible with strongyloidiasis that was diagnosed by endoscopic capsule by the surgical clinical gastroenterology group of the University of Caldas in Manizales, Colombia.

Myiasis associated with an invasive ductal carcinoma of the left breast: case study

ABSTRACT Most breast cancers originate in the ductal epithelium and are referred to as invasive ductal carcinoma. In this study we report on the clinical procedures adopted to diagnose myiasis in association with infiltrating metastatic breast carcinoma in a female patient. A 41 years old woman came to the Federal Hospital of Andaraí complaining of intense itching, warmth, redness and hardening of the breast, which had acquired the aspect of an orange peel. A lesion in the left breast was cavitated, dimpled, had fetid odor, and had fibrotic and infected air nodules filled with exudate and Dipteran larvae. The tissue was cleaned and 33 larvae were extracted. The patient was hospitalized and received Ivermectin. Eighteen of the larvae extracted from the patient were placed in 70% alcohol, and twelve were placed in a container with sterile wood shavings under controlled conditions until they metamorphosed into adults. The taxonomic identification of the flies revealed that the culprit was Cochliomyia hominivorax. A histopathological exam conducted three months earlier had revealed infiltrating ductal carcinoma. Two months after the myiasis treatment, the breast tissue had healed. The patient had waited ten days from the onset of the myiasis to seek treatment, and that delay interfered negatively in the prognosis of both the neoplasm and the myiasis. This study is relevant to public health in view of the strong social impact of myiasis.
