Primary squamous cell carcinoma of the colon is extremely rare. The etiology poorly understood, and currently, there are different hypotheses about origin this malignant neoplasm. Here, we r 87-year-old male with a moderately-differentiated nonkeratinizing colon.

colonic lipoma is a benign neoplasm that can lead to colonic obstruction but concomitant intussusception is rare in adults. in this case, colocolic intussusception due to a lipoma in the descending colon had occurred. by laparatomy, we diagnosed the problem , but reduction was impossible . so resection of the colon with mass was done and anastomosed. after surgery and 3 years follow up the pati...

CONTEXT Pancreatic heterotopia in itself is rare in the colon and to the best of our knowledge a neoplasm arising in a heterotopic tissue in the colon has not been reported.

AIMS Establishing probe-based analysis is important for developing multi-photon microscopy (MPM) to make an early diagnosis of colon neoplasm and assess its antioxidant status. Cu(I) and Zn(II) ions are trace elements which roll as cofactors of antioxidant, superoxide dismutase. However, there have been no reports on the features of MPM image using probe of Cu(I) and Zn(II) ions. Our main objec...

Metastasis into a thyroid neoplasm-tumor-to-tumor metastasis-is exceedingly rare. We describe the 28th documented case of a tumor metastatic to a thyroid neoplasm and review the literature on tumor-to-tumor metastasis involving a thyroid neoplasm as recipient.
