When traditions become dangerous: Intestinal perforation from unusual foreign body-Case report and short literature review.

Gastrointestinal perforation (GI) is a common cause of acute abdomen in the emergency department that needs a prompt surgery intervention. Nowadays, CT examinations represent the method of choice to image patients with acute abdominal pain in emergency. GI perforations by foreign bodies ingested is rare and only <1% of ingested foreign bodies are believed to cause perforation of GI. MDCT is to be considered the best imaging method for identifying foreign bodies, the perforation site and the surgical treatment to be planned reliably.

Secondary aneurysmal bone cyst in Langerhans cell histiocytosis: Case report, literature review.

Langerhans cell histiocytosis (LCH) is a rare disease of the myeloid precursor cells, it predominantly occurs in the skull and long bones as unifocal bone lesions. Aneurysmal bone cysts (ABC) are benign, expansive and lytic bone. Reports of secondary ABC occurring in LCH are rare, having only been reported twice in the skull. Here, we report the first case of LCH masquerading as ABC in a 14-month-old female child who presented with a rapidly growing mass in her left femur. The lesion had typical radiological features of ABC, and only histological examination revealed the presence of cells suggestive of LCH.
