Malign fibröz histiyositom, sıklıkla uyluk, kalça ve ekstemitelerde görülen bir yumuşak doku sarkomu tipi olup, mezenkimal dokulardan kaynaklanır. Abdominal kaynaklı malign fibröz histiyositom genellikle kötü prognozlu olup, rektumda da çok nadiren gözlenir. Elli iki yaşında kadın hasta, rektal kanama, tenesmus ve anemi semptomları ile başvurdu. Obstruktif rektal kitle nedeniyle opere edilen hastanın postoperatif patolojisi malign fibröz histiositom olarak raporlandı. Biz burada abdominoperineal rezeksiyon + uç kolostomi ile tedavi ettiğimiz, nadir görülen rektal kitlenin bir sebebi olan malign fibröz histiositom olgusunu liteatür eşliğinde sunmayı planladık.

Nonocclusive acute colonic ischemia is frequently seen in elderly population due to low blood flow and clinically it is presented with right lower quadrant abdominal pain mimicking acute appendicitis. Physical examination; blood tests, radiologic examinations and endoscopic procedures are helpful on the way to diagnosis. Although many operative techniques have been reported, right hemicolectomy with anastomosis is the most prefered surgical procedure. A 58-year-old male who had appendectomy 4 months ago, presented with right lower quadrant abdominal pain and rectal bleeding. The patient with the diagnosis of chronic renal failure had been on hemodialysis program for three times a week for 5 years. Following physical examination, colonoscopy was performed and patient was diagnosed as cecal necrosis. Patient underwent emergent operation, and right hemicolectomy along with ileotransversostomy was performed On postoperative day 9, patient was discharged without development of any postoperative complications. Although isolated cecal necrosis is a rare condition this pathology should be kept in mind in patients with chronic heart disease, chronic renal failure on routine hemodialysis program.

Parathyroid carcinoma is one of the rare endocrine tumors and constitutes 1% of the cases with primary hyperparathyroidism. Because of similar imaging modalities and similar clinical findings, it is difficult to distinguish between preoperative parathyroid adenomas and parathyroid carcinoma. A 70-year-old female patient presented with fatigue and generalized bone pain. Her laboratory tests, neck and parathyroid scintigraphy were compatible with primary hyperparathyroidism with a significantly elevated level of parathormone. With the imaging methods which supported parathyroid adenoma, the patient was operated with a presumptive diagnosis of primary hyperparathyroidism due to parathyroid adenoma. The postoperative course was unremarkable and she was discharged on the postoperative fifth day. Postoperative pathology was reported as parathyroid carcinoma developed in a parathyroid adenoma. Parathyroid carcinoma and parathyroid adenoma have similar clinically and imaging methods, it is difficult to diagnose preoperatively.
