A 55-year-old patient was diagnosed having a malignant melanoma metastatic to the small bowel as cause of an iron deficiency anemia. Although up to 60% of patients with metastatic melanoma are found to have intestinal metastases at autopsy, clinically apparent gastrointestinal involvement is rare during lifetime and often delayed after resection of the primary tumor. Diagnostic procedures include radiological imaging and endoscopic modalities. Early diagnosis is desirable for prognostic reason both in curative and palliative settings.

Metastases to the female genital tract are rare, with metastatic disease restricted to the uterus being even less frequent. The primary tumor is most often intragenital rather than extragenital. The diagnosis is usually made after occurrence of gynecological symptoms. We describe the case of a 26-year-old female, in whom a curettage for menorrhagia revealed a uterine malignancy, at first thought to be a carcinosarcoma. Biochemistry only showed iron deficiency anemia. Imaging showed discrepant results with liver lesions, suspect of neoplastic or inflammatory disease. She underwent an abdominal hysterectomy and, peroperatively, a frozen section of a mass in the liver hilus demonstrated a cholangiocarcinoma. The diagnosis of a uterine metastasized cholangiocarcinoma was made. We emphasize the fact that uterine metastases have to be excluded in every woman with abnormal uterine bleeding and a personal history of malignancy. However, our case also indicates that gynecological metastatic disease may be the first presentation of an extragenital primary neoplasm.

Adenosquamous carcinoma is a rare colorectal tumor with few cases described in the literature; no children have been reported. A 12-year-old-girl presented tenesmus, diarrhea, and iron deficiency anemia. Intestinal bowel disease was suspected, colonoscopy and biopsy were performed and the diagnosis was a squamous cell carcinoma. Chemoradiation therapy based on last colorectal cancer guidelines was started. Complete regression of the primary tumor was observed with lymph node progression. The pathology report of the lymphadenectomy revealed metastasis of adenosquamous carcinoma, although there was not any adenomatous component in the first biopsy. The patient presented progression with liver metastases, despite stable local disease due to response to first-line treatment of the squamous component.

The National Cancer Institute reports high incidence of renal cell carcinoma (RCC) in the US compared to other regions. However, pancreatic and periampullary metastasis are uncommon when only 17% of the RCC cases metastasize overall. We herein present a case series of four patients with periampullary or pancreatic metastatic disease following complete resection of RCC, evaluating their occurrences and outcomes. We reviewed the cases of four male patients retrospectively, mean age 75 years (range 65 - 87) who had a previous history of nephrectomy for RCC. They experienced recurrence with periampullary (two patients) or pancreatic (two patients) metastatic disease between 0 and 108 months (mean time 41.5 months) following primary tumor resection. In patients with periampullary metastasis, one had asymptomatic presentation with progressive dilatation of the pancreatic duct noted on surveillance CT scans. The other patient had iron deficiency anemia and melena with esophagogastroduodenoscopy (EGD) findings of large fungating infiltrative ulcerating mass in the area of the duodenal papilla (the only patient with metastasis to other sites: lungs and colon). As for those with pancreatic metastasis, one patient presented with hematuria and abdominal pain and was found to have pancreatic metastasis at the time of RCC diagnosis. The other patient was admitted for further workup of a mass in the pancreatic tail upon surveillance. Pathologic findings included high grade RCC in the metastatic foci. Management of such patients included: distal pancreatectomy in two patients without chemoradiation, one was awaiting Whipple procedure and received four cycles of sunitinib, while the last was a poor surgical candidate and received aminocaproic acid. Three patients are still alive to date. Optimal management is challenging given the very high risk of delayed relapse following tumor resection of the localized disease, leaving such cases with a very poor prognosis. Therefore to enhance survival, it is imperative to have careful stage-dependent surveillance in patients who have undergone a prior resection of RCC. We emphasize the importance of raising awareness for this unusual presentation. Disease recurrence as a pancreatic mass or hepatobiliary ductal dilatation might be more frequent than previously reported.
