Mucinous neoplasm is a rare malignancy of the gastrointestinal tract, the most common site being the appendix. There are different types of mucin producing tumours that can occur in the appendix, which can be benign as well as malignant. Mucin produced by these tumours results in ascites that makes it palpable as jelly belly.

Malignant melanoma of the gastrointestinal tract is an uncommon neoplasm that could be primary or metastatic. Small intestine represents the most common site for the metastatic melanoma; however, it could be found anywhere in the gastrointestinal tract. Intussusception is a rare cause of intestinal obstruction in adults compared to children. In 90% of the cases, the underlying cause can be foun...

stromal tumor that develops from gastro-intestinal (GI) mesenchymal cells from the esophagus to the rectum. Before 1990, most investigators thought these mesencgymal cell tumor to be the neoplasm from smooth muscle of gastrointestinal tract, and considered that these tumors were one kind of leiomyoma, leomyosarcoma or leiomyoblastoma. With the advent of immuno-chemical staining and ultra-struct...

Precursor B lymphoblastic lymphoma is a high-grade neoplasm arising from precursor lymphocytes of B-cell lineage. Extranodal sites such as the skin and bone are often involved, but gastrointestinal lesions of this disease are rarely encountered. Due to the infrequency, macroscopic forms of the gastrointestinal lesions have not been fully described. In this report, we present a case of precursor...

The involvement of the appendix by lymphomas, both primarily or secondarily, is extremely rare; primary lymphomas account for less than 0.02% gastrointestinal neoplasm. We present rare case a patient who debuts with low bleeding as main symptom. Colonoscopy found an extra mucosal tumour on posterior aspect ceccum and from appendicular orifice.

INTRODUCTION Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and account for 0.1%-1% of gastrointestinal malignancies. Meckel's diverticulum (MD) is the most prevalent congenital abnormality of the gastrointestinal tract (0.3%-4.0%). DISCUSSION Their clinical presentation is strongly related to the occurrence of complications or th...
