Retrorectal epidermal inclusion cysts are rare congenital cystic lesions, mostly an incidental finding usually diagnosed in middle-aged women. Surgical resection is the main stay of treatment and 3 operative approaches commonly used: abdominal, trans-sacral/coccygeal (posterior), combined abdomino-posterior depending on nature location lesion.

Mesenchymal hamartoma (MH) of the liver is an uncommon benign lesion related to ductal plate malformation. It is usually cystic and mainly composed of myxoid mesenchymal tissue with tortuous or cystic bile ducts. In order to characterize the clinicopathological features of MH, the Korean Gastrointestinal Pathology Study Group collected a total of 17 MH cases diagnosed in 7 hospitals from 1992 t...

UNLABELLED Mammary hamartoma is an uncommon benign lesion. The frequency of the tumor is reported between 0.04 -1.15% and it accounts for 4.8% of all benign breast tumors. The lesion may be under-diagnosed by the clinician because of the varied clinical presentation or by the pathologist, as the microscopic appearance is not distinctive. A case of left sided mammary hamartoma in a 46-year-old f...

Folliculocystic and collagen hamartoma is a newly described complex hamartoma characterized by abundant collagen deposition, concentric perifollicular fibrosis, and keratin- filled infundibular cysts that are visible on histopathological examination. Here, we report the case of a 19-year-old Korean man who had large brownish infiltrated plaques with numerous follicular comedo-like openings and ...

Retrorectal tumors are very rare but well defined pathological entities in the literature. Also, an extrasphincteric fistula is a very rare form of perianal fistula which makes our case a very unusual and rare one, especially by the fact that it was successfully treated with the first operation and without protective stoma formation. The patient was first treated in hospital for a retrorectal a...

We present a full-term male neonate with no relevant family history, with prenatal diagnosis using ultrasonography and magnetic resonance imaging (MRI) of cystic lesion that supports the differential diagnosis between choledochal cyst and normal gall bladder. Initial abdominal ultrasound (Fig. 1) showed an intrahepatic cystic lesion suggestive of mesenchymal hamartoma or choledochal cyst. In a ...
