Adult-onset colonic intussusception is a rarely encountered condition that leads to large intestinal obstruction with time. Patients often present with a variety of symptoms that are non-specific making it challenging to arrive at a definitive diagnosis. This is worrying as diagnostic delay could lead to a significant increase in morbidity and mortality. We wish to present and describe a case of an atypical endoscopic finding of colocolic intussusception secondary to ascending colon cancer. Sixty-seven-year-old lady was referred for 1 month's duration of passing melenic stools with mucus followed by a week's complain of hematochezia.Clinical examination and other relevant blood results were unremarkable except for iron deficiency anemia.Initial colonoscopy revealed a large mass within the splenic flexure with inconclusive biopsies. A more detailed colonoscopy repeated the following day revealed a massive, black-to-yellowish lesion within the splenic flexure with no viable mucosa seen. Colonic bezoar was initially suspected, however various endoscopic retrieval methods proved futile. Switching to a slimmer diagnostic gastroscope, the colon was carefully negotiated until a large ulcer was found within the ascending colon, adjacent to the mass' origin.An emergency CT abdomen and subsequently extended right hemicolectomy performed revealed a colocolic intussusception with sealed perforation secondary to an ascending colonic mass acting as an intussusceptum.Histopathology evaluation confirmed an ascending colon adenocarcinoma (pT2N0M0) amidst a background of extensive ischemic changes. Endoscopic descriptions of colonic intussusception are unusual given their rarity. Furthermore, these lesions can mimic a colonic bezoar as a result of fecal accretion and this can ultimately lead to false diagnostic and therapeutic decisions. In such instances, clarification with a CT scan before management decision can potentially avert unnecessary endoscopic intervention and complications.

Over the years, the occurrences of different types of skin disorders arising from radiation sites have been observed and studied. Examples include autoimmune blistering diseases such as pemphigus, pemphigoid, and interface or inflammatory reaction patterns such as lichen planus, lupus erythematosus, and Stevens-Johnson syndrome. The phenomenon whereby a new skin disorder arises from a previously healed or irradiated site is called an isotopic response, described as a type of Koebner phenomenon. Ionizing radiation itself can profoundly affect the skin. Both early and late changes can present, which typify the progression of changes following irradiation of the skin. Herein, we report a rare case of labetalol-associated lichen planus pemphigoides that occurred at the site treated with radiation for a soft tissue malignancy after 19 years as a result of an isotopic response.The rash was well-controlled after therapy and kept a 4-year remission. The same skin reaction recurred after the reintroduction of labetalol 4 years later.
