Colorectal endoscopic submucosal dissection: predictors and neoplasm-related gradients of difficulty
BACKGROUND AND STUDY AIM The role of colorectal endoscopic submucosal dissection (ESD) is standardized in Japan and East Asia, but technical difficulties hinder its diffusion. The aim was to identify predictors of difficulty for each neoplasm type. METHODS A competent operator performed all procedures. ESD difficulty was defined as: en bloc with a slow speed (< 0.07 cm 2 /min; 30 × 30 mm ne...

Extent neuroendocrine differentiation can be encountered in many human neoplasm derived from different organs and systems using immunohistochemistry and ultrastructural techniques. The tumor cells' behaviors resemble those of neurons and neuroendocrine cells. The presence of neuroendocrine differentiation reputedly appears to be associated with a poorer prognosis than the adenocarcinoma counter...
neuroendocrine cells. Neuroendocrine cells are distributed throughout the gastrointestinal tract, pancreas, lung, thyroid, adrenal gland, and many other organs (1). The gastrointestinal tract has the largest population of neuroendocrine cells, but neuroendocrine malignancies are rare in the colon or rectum (2), accounting for less than 1 percent of all colorectal cancer (3).

Choriocarcinoma (CC) is a malignant tumor of trophoblastic tissue composed cytotrophoblastic, intermediate and syncytiotrophoblast cells. predominantly has gestational origin. The non-gestational type said to arise from the gonads pluripotent germ It rapidly invasive metastasizes widely, but it good response chemotherapy once identified.

Sarcomatoid carcinoma of prostate is an extremely rare but aggressive neoplasm. It is generally associated with a poor prognosis. About 100 cases have so far been reported in the English literature. We report the case of a 64-year-old male with a very rapidly progressive disease that ultimately involved the whole lower urinary tract and rectum. The management of this case along with etio-pathog...
Abstract Introduction We report a case of small cell carcinoma the prostate (SCCP) which is rare, high-grade malignant neoplasm accounting for 1% all cancers (CPa). Case Presentation A 56-year-old male patient initially presented to primary care with six-month history frequency, nocturia and pain in perineal region when seated. positive family-history CPa was noted, serum PSA 11.58, rectal exam...
Benign cystic ovarian teratoma is the most common ovarian neoplasm accounting for 10–25 % of ovarian tumors. Complications of cystic teratomas include torsion (16 %), malignant degeneration (2 %), infection (1 %), and rupture (1 %). It can rupture into the bladder, small bowel, rectum, sigmoid colon, vagina, abdominal wall, and peritoneal cavity. We report a case of ovarian dermoid perforating ...
