INTRODUÇÃO: Metástases esplênicas solitárias oriundas de carcinomas colorretais são raras, com 41 casos descritos na literatura inglesa até 2007. Muitos pacientes são assintomáticos, e o diagnóstico é quase sempre feito por imagens radiológicas ou por elevações sanguíneas do antígeno carcinoembrionário (CEA), solicitados no seguimento pós-operatório desses pacientes. Relato do caso: Homem de 54 anos foi submetido à colectomia esquerda por carcinoma de sigmoide. O tumor foi estadiado como T3N0M0 e permaneceu assintomático por dez meses, com níveis normais de CEA. Notou-se, então, significativa elevação do antígeno e a tomografia computadorizada do abdômen revelou massa no polo inferior do baço, suspeita de metástase. A laparotomia confirmou o achado propedêutico, sendo realizada esplenectomia. O diagnóstico anatomopatológico foi de adenocarcinoma metastático, sem invasão dos linfonodos. A sobrevida acompanhada do paciente foi de 14 meses, livre de recidiva. CONCLUSÃO: Metástases esplênicas isoladas de carcinoma dos cólons são raras, e a esplenectomia oferece possibilidade de sobrevida expressiva.Solitary metastatic metastasis from colorectal neoplasms is rare. Only 41 cases have been reported in the English literature until 2007. Most patients are asymptomatic, and the diagnosis is usually done by imaging studies or CEA (carcinoembrionic antigen) blood increases, which are required in the postoperative follow-up period. Case report: A 54-year-old man underwent an extended left colectomy for sigmoid colon cancer. The tumor was staged as T3N0M0. During ten months of the follow-up period, the patient remained asymptomatic with normal levels of laboratory tests, including CEA measurement. Then, there was a significant elevation of CEA, and the abdomen computed tomography revealed a mass in the spleen considered as an isolated metastasis. The patient underwent splenectomy. Histological diagnosis confirmed a metastatic adenocarcinoma with no lymph nodes invasion. The patient has been symptom-free during the 14 months of follow-up with normal blood CEA levels and negative radiological studies. CONCLUSION: Solitary spleen metastasis from colon carcinoma is rare, and splenectomy provides an expressive improvement in the survival.

To analyze the clinical and pathological features of heterotopic pancreatic tissue in abdominal digestive organs.We retrospectively studied 18 patients with histologically diagnosed heterotopic pancreas. Clinical and histopathologic data were reviewed. Heterotopic pancreatic tissues were classified in three histological models: Type I consists of three components of normal pancreas (acini, ducts and islets), type II with two components and type three with only one component.The mean age was 52.7 years, ranging from 34 to 73 years, nine of them men and nine women. Symptoms were observed in only four patients, and their lesions were diagnosed by gastroscopy. The remaining 14 were asymptomatic and their anomalies were discovered accidentally. Most of the lesions were located in the upper gastrointestinal tract: seven (38.9%) in the stomach, six (33.3%) in the duodenum and three (16.6%) in the jejunum. Heterotopia was mostly located in the submucosa (83.3%) but was also observed in the muscularis propria and in the sub-serosa. In seven specimens (38.9%) all pancreatic components were found (type I), in eight (44.4%) exocrine glands and excretory ducts were present (type II) and in three (16.7%) only exocrine tissue was observed (type III).Pancreatic heterotopia is rare. Patients with pancreatic ectopia diagnosed by pathological study, whether asymptomatic or with mild symptoms, should be observed. Lesions incidentally detected during surgeries need to be removed by conservative procedures.
