A rare case of peritoneal Xanthogranuloma in a 23-year-old woman.

Xanthogranuloma is a very rare tumor when it comes to abdomen. Macroscopically, it is characterized by formation of multiple, golden yellow or bright yellow nodules, whereas histologically, the lesion is predominantly composed of foamy cells mixed with acute and chronic inflammatory cells. We report a case of 23-year-old woman presented to the hospital with chronic constipation, colic abdominal pain and recurrent vomiting. The patient had a history of sigmoid colon volvulus. Radiological investigations showed sigmoid colon elongation, multi-density formations in the left iliac region and pelvis and a small amount of pelvic fluid. Laparoscopy followed by excisional biopsy of the formations were made, and pathological examination showed Xanthogranuloma with no ovarian parenchyma. Hence, Xanthogranuloma should be considered as a differential diagnosis for idiopathic abdominal pain. Laparoscopy and excisional biopsy are suggested procedures when short-term therapy is concerned.
