PURPOSE Primary tumors of the retrorectal space in adults are very rare. Most of them are benign masses, but malignant masses are reported on occasion. This study aimed to investigate the clinicopathological features of retrorectal tumors. METHODS The medical records of fifteen patients who underwent surgical resection of a retrorectal tumor from March 2002 to April 2010 in our hospital were ...

We report a case with prenatally diagnosed large cystic-solid mesenchymal chest wall hamartoma. An attempt of conservative management was made however repeated intralesional hemorrhage led to enlargement and severe anemia which required urgent resection at the age of 8 weeks. The infant had an unimpaired development over a follow-up of 4 years.

Cystic hamartoma refers to rare benign lung tumors. The literature describes 17 cases of this disease. tumor may look like multiple bilateral cysts or a solitary single-chamber multi-chamber cyst large size, which makes it difficult diagnose. disease can be complicated by spontaneous pneumothorax. itself often looks An observation 52-year-old man complaining chest pain and shortness breath is p...

In pulmonary pathology the term "hamartoma " is most commonly applied to a group of tumours in adults which usually contain cartilage as a constituent and arise from connective tissue (Sutherland, Aylwin, and Brewin, 1953). Willis (1958) does not think such growths are named correctly and gives good reasons for regarding them as acquired mixed tumours. On the other hand the mass replacing the e...

We report the case of an asymptomatic 51-year-old man, presenting with chest X-ray abnormalities consisting in multiple pulmonary nodules; the diagnosis of mesenchymal cystic hamartoma of the lung was made by an open lung biopsy, revealing both nodules of mesenchymal cells and cysts with a lining of normal or metaplastic epithelium. Clinical and pathological characteristics of this rare entity ...

This report describes a case of mesenchymal cystic hamartoma of the liver with diagnostic imaging work-up using only ultrasound and MRI. We demonstrate an approach starting from the pediatrician's physical exam culminating in surgical resection and pathologic confirmation with an emphasis on MR imaging.

Retrorectal epidermoid cyst is one of the developmental cysts which arise from remnants of embryonic tissues. We report a rare case of retrorectal epidermoid cyst, initially diagnosed as an ovarian tumor. Serum SCC value as tumor marker was elevated to the high level. Laparoscopy revealed ovaries, uterus and other pelvic organs were all normal. This tumor existed in the retroperitoneal cavity a...
