A 25-year-old man sought the hospital complaining of right-flank pain that had started two days earlier, followed by nausea and fever. Leukocytosis was found in a hemogram, and ultrasound showed thickening of the appendix wall. He underwent an operation and his appendix was removed. Histological examination revealed the presence of a well-formed granuloma containing remnants of Schistosoma mansoni eggshells (Figures A and B ). Figure C shows the mucosa of the appendix (thick arrow) and inflammatory infiltrate with predominance of polymorphonuclear neutrophils in the submucosa; areas with fibrinous material are also seen (thin arrow). Parasitological stool examination was positive for Schistosoma mansoni eggs, and the patient was treated with a single oral dose of praziquantel (50mg/kg of body weight, divided into two parts taken with a four-hour interval). Six months later, he was examined at our outpatient clinic and was found to be asymptomatic.
O paciente, de 25 anos, procurou o hospital com dor no flanco direito de início havia dois dias, seguido de náuseas e febre. O hemograma revelou leucocitose e o ultra-som mostrou espessamento da parede do apêndice. Ele foi operado e teve o seu apêndice retirado. O exame histológico do apêndice revelou a presença de granuloma bem formado em torno de restos de cascas de ovo de Schistosoma. mansoni (Figuras A e B ). Na Figura C, vê-se a mucosa do apêndice (seta grossa) e infiltrado inflamatório com predomínio de polimorfonucleares na submucosa; há ainda áreas com material fibrinoso (seta fina). O exame parasitológico das fezes mostrou-se positivo para ovos de Schistosoma mansoni e ele foi tratado com dose única oral de praziquantel (50mg/kg de peso em duas tomadas com intervalo de quatro horas). Seis meses após a cirurgia ele foi examinado em nosso ambulatório e encontrava-se assintomático.
