English abstract
Abdominal pain is a common clinical presentation that can be caused by a variety of
conditions ranging from self-limited to serious pathologies. It may be the first symptom
of an occult malignancy, especially in elderly patients or in the presence of systemic
manifestations such as weight loss, fever, fatigue, and anorexia. However, functional
gastrointestinal disorders, vascular pathologies, renal diseases, genitourinary illnesses, and
chronic infections should also be considered as possible causes of abdominal pain. We
report a case of a 59-year-old female who presented to our center with a three-month history
of abdominal pain and weight loss. Initial workup revealed the presence of a suspicious
hepatic mass, circumferential wall thickening of the transverse colon, and pericardial
effusion. Exploratory laparotomy with a surgical biopsy of the hepatic mass was performed,
and the histopathologic picture was consistent with actinomycosis. The patient was treated
successfully despite the initial diagnostic challenges and complicated hospital course.
