Hodgkin lymphoma (HL) commonly presents as nodal disease, but in a subset of cases, the disease primarily develops in extranodal sites. Primary classical HL of the gastrointestinal (GI) tract is an extremely rare occurrence. Primary nature of the disease is confirmed after a complete lymphoma work up including chest radiograph, computed tomography scan, peripheral blood, and bone marrow studies. Only a few cases of primary GI lymphomas with limited immunohistochemical or molecular confirmation have been reported in literature...

Primary squamous cell carcinoma (SCC) of the rectum is a very rare entity making up to 0.1-0.25/1,000 cases of all colorectal cancers. Here, we present the case of an otherwise healthy 63-year-old female who presented with progressive pelvic discomfort, new onset constipation and a complex mass in presacral region on imaging which was proved to be poorly differentiated SCC of the rectum. The correct diagnosis was achieved by fine needle aspiration (FNA) via endoscopic ultrasound (EUS-guided FNA) as initial conventional colonoscopy failed to establish the diagnosis...

Neuroendocrine tumors can arise from any portion of the gastrointestinal tract including the colon and rectum. In the scope of all colon and rectal malignancies, they are a rare cause of colorectal carcinoma. Relating to their pluripotent neuroendocrine cellular origins these carcinomas can produce a variety of biologically active peptides with several resultant paraneoplastic syndromes. One of these paraneoplastic syndromes is the syndrome of inappropriate antidiuretic hormone (SIADH). In the SIADH, supraphysiologic levels of vasopressin (antidiuretic hormone, AVP) precipitates exorbitant free water retention and resultant electrolyte abnormalities, most notably hyponatremia...

The term collision tumor is used to describe two neoplasms occurring in the same anatomic location with juxtaposition of different tumor elements. Such a coexistence of tumors anywhere in the body is relatively rare. We report a case of 32-year-old female with collision tumor of rectum. The tumor showed two distinct histological patterns with predominant component consisting of malignant melanoma and a minor component of squamous cell carcinoma. The morphological picture of collision was further confirmed by specific immunohistochemical profile of the two tumors...

Neuroendocrine cells often coexist with exocrine neoplasms of the gut and each component is normally present in a variable range. Despite this frequent association, mixed exocrine-neuroendocrine carcinomas are rare. This entity is known as adenoneuroendocrine carcinoma (MANEC) and each of its malignant components represents at least 30%. In contrast, there are only a few reports of another rare association of an adenoma and a well differentiated neuroendocrine tumor (NET) in the colon and rectum. The term mixed adenoneuroendocrine tumor (MANET) was suggested due to its indolent behavior and distinct morphological characteristics with mild to moderate nuclear atypia and low number of mitoses1...

Gastrointestinal (GI) metastasis from a primary breast carcinoma is uncommon, with the rectum being one of the least reported sites in the literature. We report a case of a 79-year-old woman who underwent treatment for an infiltrative lobular carcinoma of the right breast with nodal involvement, and 10 years later developed recurrence in the form of rectal metastasis. Spread to the GI tract is most commonly seen with lobular breast carcinomas. Any patient with a history of breast cancer presenting typically or atypically with abdominal symptoms or altered bowel habit should raise a high index of suspicion for recurrent or metastatic disease...

An 81-year-old man with Cushing syndrome was referred for a Ga-DOTATATE PET/CT study to investigate for an ectopic source of adrenocorticotropic hormone. The scan demonstrated mildly increased octreopeptide uptake at a rectal mass and focal uptake at multiple regions throughout the bone marrow of the axial skeleton, consistent with metastases. A subsequent F-FDG PET/CT study was performed for further evaluation and demonstrated markedly increased metabolism at the previously identified rectal mass, in addition to the liver and multiple regions throughout the skeleton...

Cancer invasion of the lamina propria is an important pathological finding. However, the clinicopathologic features and diagnostic accuracy of intramucosal carcinoma assessment in colorectal carcinoma (CRC) are unknown. In this study, intramucosal CRCs were reviewed in institutions affiliated with the Japanese Society for Cancer of the Colon and Rectum, and 32 cases with invasion of the lamina propria were identified. Next, a consensus meeting was held to select cases with a high consensus about the presence of invasion, which were reviewed by one Western pathologist for confirmation...
