Liposarcomas those are malignant soft tissue tumors often occur in large sizes in the retroperitoneum and abdomen due to their silent clinic. Excision with negative margins is the gold standard of treatment. A case operated on for a giant intraabdominal liposarcoma is being reported. A giant soft tissue tumor filling the whole abdomen was determined in the computed tomography scan. Core biopsy was obtained and demonstrated a well-differentiated liposarcoma. A 15 kg of mass 44x30x14 cm in size was excised en-bloc. Pathological examination of this tumor showed a well-differentiated liposarcoma with mixoid parts. No recurrence was observed in two years of follow-up despite any adjuvant therapy. This is to be one of the largest retroperitoneal sarcomas in the literature.
Spontaneous rupture of ovarian dermoid cyst and chronic abdominal spillage of its content is a very uncommon condition, which causes granulomatous peritonitis and can be confused with peritoneal carcinomatosis. Here is presented such a case of ruptured dermoid cyst causing chronic granulomatous peritonitis with radiologic findings mimicking peritoneal carcinomatosis.
