Colonic adenocarcinoma revealed by metastatic anorectal fistula is rare, with few cases in the literature. Such lesions can be taken for the more common manifestation of a benign perianal abscess or fistula. Once diagnosed, the management of such conditions remains controversial. We herein report two cases with perianal fistula that were subsequently found to have developed perianal adenocarcin...

A 45-year-old female patient underwent right hemihepatectomy for metastatic rectal adenocarcinoma. Preoperative imaging demonstrated an area of focal nodular hyperplasia (FNH) in segment VIII and metastatic carcinoma in segment VI of the liver. Gross and microscopic examination of the former lesion showed features typical of FNH with an intralesional metastatic adenocarcinoma. To the best of ou...

Cases of primary colorectal adenocarcinoma metastasized to the palatine tonsil are extremely rare. To the best of our knowledge, only 10 cases have thus far been previously documented in the English literature. A 37-year-old Chinese woman presented with a right palatine tonsil swelling and odynophagia 5 months after a surgical resection of rectal adenocarcinoma was performed. The patient underw...

A 56-year-old female with a background of metastatic rectal adenocarcinoma presented with a subglottic mass causing biphasic stridor. Transoral laser microsurgery and the use of fibrin glue prevented the need for tracheostomy. Six months postoperatively there was no evidence of recurrence. Laryngeal metastasis of colorectal adenocarcinoma, although remarkably rare, is perhaps more prevalent tha...

Peritoneal pseudomyxoma is a pathological condition that compromises the peritoneum, characterized by the production of large quantities of mucinous liquid, which progressively fills the peritoneal cavity, originating in general from mucinous appendicular or ovarian tumors. We report a peritonial pseudomyxoma associated with mucinous adenocarcinoma of the appendix synchronic with adenocarcinoma...

Synchronous cancers of different primary origin are rare. Here, we describe the case of a patient with concomitant diagnoses of rectal adenocarcinoma and splenic marginal zone lymphoma (smzl). A 57-year-old woman initially presented with abdominal pain. Physical examination and computed tomography demonstrated massive splenomegaly, and a complete blood count revealed microcytic anemia and lymph...

BACKGROUND Rectal cancer with rectal prolapse is rare, described by only a few case reports. Recently, laparoscopic surgery has become standard procedure for either rectal cancer or rectal prolapse. However, the use of laparoscopic low anterior resection for rectal cancer with rectal prolapse has not been reported. CASE PRESENTATION A 63-year-old Japanese woman suffered from rectal prolapse, ...
