[Appendicular actinomycosis as a cause of ileocecal mass in children: Case report].

INTRODUCTION

Appendicular actinomycosis is a rare disease produced by cecal appendix invasion by Actinomyces gender bacteria after a predisposing cause that disrupts mucosal barrier, such as acute appendicitis. The highest frequency appears in adults; however, there are cases in paediatric age described in literature. The aim of this article is to introduce a case of appendicular actinomycosis in a child with atypical presentation and to review the literature.

CLINICAL CASE: 10-year-old boy transferred to our hospital due to intraoperative finding at a different centre of a right flank tumor, without identification of cecal appendix. After completing the study with image tests, the patient was re-intervened with the diagnosis of complicated acute appendicitis. Intraoperatively, an organized plastron lacking of acute inflammatory signs was found. Post-surgical evolution was positive with conventional antibiotic treatment. Histological study of the specimen revealed an appendicular actinomycosis, so antibiotic treatment was widened in an outpatient basis and predisposing diseases were ruled out.

COMMENTS: Appendicular actinomycosis is an infrequent cause of appendicitis that can simulate an intra-abdominal tumor in children and adults. It is necessary to rule out predisposing diseases and to administer an adequate antibiotic treatment.
