Estenosis gastroduodenal: una complicación infrecuente del carcinoma gástrico de células en anillo de sello / Upper gastrointestinal stenosis: a rare complication of gastric-signet ring cell carcinoma / Estenose gastroduodenal: uma complicação rara do carcinoma gástrico de células em anel de sinete

El carcinoma de células en anillo de sello es una variante histopatológica de cáncer gástrico que se encuentra en aumento, se caracteriza por un mal pronóstico. Se presenta el caso de un hombre joven al que se le hizo este diagnóstico en el contexto de una complicación rara como es el síndrome de estenosis gastroduodenal.

Signet ring cell carcinoma is a histopathological variant of gastric cancer that is increasing and is characterized by a poor prognosis. We present the case of a young man who underwent this diagnosis in the context of a rare complication such as upper gastrointestinal stenosis syndrome.

O carcinoma de células em anel de sinete é uma variante histopatológica do câncer gástrico que está aumentando e é caracterizado por um mau prognóstico. É apresentado o caso de um jovem que recebeu este diagnóstico no contexto de uma complicação rara como a síndrome de estenose gastroduodenal.

Mieloptisis y cáncer gástrico: Una asociación infrecuente / Myelophthisis and gastric cancer. An unusual association

Se denomina mieloptisis a la infiltración de la médula ósea por células no hematopoyéticas. En pacientes con cáncer gástrico esta invasión es extremadamente infrecuente y la supervivencia suele ser menor a tres meses. Presentamos el caso de un hombre de 35 años con compromiso de la médula ósea secundario a un carcinoma gástrico difuso de células en anillo de sello.

The infiltration of the bone marrow y non-hematopoietic cells is called myelophthisis. In patients with gastric cancer, this invasion is extremely infrequent and the survival is usually less than three months. We present the case of a 35-year-old man with bone marrow involvement secondary to diffuse gastric carcinoma of signet ring cells.

Bicytopenia and leukoerythroblastosis: a rare initial presentation of signet ring cell gastric adenocarcinoma

Gastric adenocarcinoma is a common neoplasia and is responsible for up to 30% of the overall deaths due to cancer. Advanced disease is mostly characterized by peritoneum, liver, and lung involvement. The spread of the disease to the bone is rare, and bone marrow dissemination is even rarer. In this setting, leukoerythroblastosis may be the initial manifestation of the disease. The authors report the case of a 64-year-old Caucasian man who sought medical care complaining of back pain, weakness, and weight loss. The physical examination revealed pallor, and the laboratory work-up depicted severe anemia and thrombocytopenia; the peripheral blood smear was consistent with leukoerythroblastosis. The ongoing investigation through a bone marrow biopsy showed massive involvement of the bone marrow by a signet ring cell adenocarcinoma. During hospitalization, the patient presented melena, and an upper digestive endoscopy depicted an ulcerated and infiltrative lesion in the cardia, upon which the histological examination revealed a signet ring cell adenocarcinoma. This case highlights the bone marrow invasion represented by bicytopenia and leukoerythroblastosis as the initial manifestation of this histological type of gastric cancer. Although treatment attempts were made with chemotherapy and radiotherapy, the patient died early on, showing the aggressive behavior of this form of tumoral presentation.

Adenocarcinoma gástrico difuso en un niño de 10 años: reporte de un caso / Diffuse type of gastric adenocarcinoma in 10 years old boy: report of a case

El objetivo del presente estudio fue presentar un caso extremadamente raro de adenocarcinoma gástrico difuso con células en anillo de sello en un niño de 10 años. Se presenta un niño de 10 años, con un tiempo de enfermedad de 12 meses con sintomatología de disfagia a sólidos, luego a líquidos, pérdida de peso, anorexia, astenia, mareos, vómitos y dolor en el hipocondrio izquierdo. Presenta desnutrición crónica, marcada palidez y máculas "café con leche" en tronco y extremidades. Los exámenes de laboratorio evidenciaron 7,5 gr de hemoglobina, albúmina 2,62 gr, thevenon en heces positivo. Una ecografía abdominal mostró masas periaórticas y lesiones difusas a nivel hepático. A la endoscopía se observó lesión elevada esófago-gástrica que obstruye la luz. A nivel subcardial tumoración de 3 cm de bordes irregulares, superficie erosionada y sangrante al roce. Se realizó biopsia múltiple. Murió un año después por metástasis generalizada. Nació de parto normal, de madre primigesta, con 3 500 gr de peso. Antecedentes familiares: tía abuela materna falleció de cáncer gástrico. La biopsia mostró un adenocarcinoma difuso con presencia de células en anillo de sello, PAS positivo y a la inmunohistoquímica fue positiva a la CK 8.

We report a rare case of diffuse type of gastric cancer with signet ring cells in 10 years old boy who was admitted with a 12 months history with weight loss, dysphagia to solids first and to liquids later, anorexia, fatigue, dizziness, vomiting and later, with pain in the left upper quadrant. On examination, he appeared pale, malnourished, with café-au-lait spots over the trunk and extremities. Laboratory tests showed; Hb 7.5 g, albumin 2.62 g, Thevenon positive on stools. Abdominal ultrasound examination showed periaortic masses and diffuse space occupying lesions in the liver. Endoscopic examination of the stomach showed multiple elevated tumor lesions. One located at 3 cm on the subcardial region presented irregular borders, partially eroded, that bleed easily when rubbing its surface. Multiple biopsy samples were taken. They showed a diffuse gastric signet cell type carcinoma of the stomach. Immunohistochemistry was positive to CK 8. The patient died a year later with wide spread metastasis. The boy was born through a normal delivery after a normal pregnancy to a primipara mother. His family history recorded a grandmother aunt dying of gastric cancer.

Metástasis de carcinoma de células en anillo de sello al cuello uterino / Metastasis of signet-ring cell carcinoma of the cervix

Las metástasis de carcinomas extragenitales al útero es rara y el compromiso al cuello uterino es excepcional, especialmente del tipo histológico de carcinoma de células en anillo de sello. Se presentan tres casos encontrados en 240 adenocarcinomas cervicales (1,25 por ciento) diagnosticados entre 1979-2012. Dos casos se presentaron en pacientes de 48 y 56 años originados en carcinomas lobulillares infiltrantes de la mama diagnosticados previamente. La primera paciente está viva a 19 meses del diagnóstico ginecológico y la segunda falleció a los 14 meses, siendo en ambas un hallazgo histológico incidental en cirugías realizadas por patología ginecológica benigna. El tercer caso se presentó en una paciente de 43 años que debutó por metrorragia y tumor cervical y fue originado en un carcinoma gástrico infiltrante difuso, encontrado en forma sincrónica y fallece a los 2 meses del diagnóstico. Se revisan los criterios diagnósticos entre metástasis y carcinoma primario de células en anillo de sello del cuello uterino y el aporte al diagnóstico de la histología convencional, la inmunohistoquímica y la tipificación molecular de HPV. Conclusión: Se concluye que la metástasis de carcinoma de células en anillo al cuello uterino es rara y el pronóstico es malo. La citoreducción y la quimioterapia podría tener un rol para casos seleccionados de carcinomas metastásicos de origen mamario y que estos casos no deberían ser considerados un evento preterminal.

The uterine metastatic involving of extragenital carcinomas is rare, especially the signetring cell type. Three of such a cases were found in 240 cases of adenocarcinomas of uterine cervix (1.25 percent) diagnosed between 1979-2012. Two of these cases occurred in patients aged 48 and 56 years with infiltrating lobular carcinomas arising in the breast previously diagnosed. The first patient is alive at 19 months after diagnosis and the second is deceased at 14 months after diagnosis. In both cases, the metastasis to the cervix was an incidental histological finding in surgeries performed by benign gynecological pathology. The third case was identified in a 43-years old patient who debuted with metrorrhagia and cervical tumor which was originated in a diffuse infiltrating gastric carcinoma that was found synchronously and she is dead at 2 months after diagnosis. The diagnostic criteria between metastases and primary cervix carcinoma of signet ring cells and the contribution to the diagnosis of conventional histology, immunohistochemistry and molecular typing of HPV are reviewed. The metastasis of signet ring cell carcinoma to the uterine cervix is rare and the survival is poor. Conclusion: The role of cytoreduction and chemotherapy for selected cases of metastasis from breast carcinomas should be considered and in such a case the gynecological involvement should not be considered a preterminal event.

Cutaneous metastases of signet-ring cell colorectal adenocarcinoma

Colorectal cancer is a common malignancy in our clinical practice and it often evolves to a metastatic stage. Cutaneous dissemination, however, is a rare form of presentation of this disease. This study reports the case of a 38-year-old female patient that, even after neoadjuvant chemotherapy, presented cutaneous metastases of signet-ring cell colorectal adenocarcinoma. The malignancy proved to be extremely aggressive, without response to clinical therapy nor allowing surgical management, leading the patient to death about six months after the diagnosis. (AU)

O câncer colorretal é uma neoplasia comum em nossa prática clínica e frequentemente evolui ao estágio metastático. Disseminação cutânea, entretanto, é uma forma rara de manifestação da doença. Apresentaremos aqui o caso de uma paciente de 38 anos que, mesmo após a realização de quimioterapia neoadjuvante, apresentou metástases cutâneas de um adenocarcinoma colorretal com células em anel de sinete. A neoplasia demonstrou-se extremamente agressiva, não respondendo ao tratamento medicamentoso nem permitindo o tratamento cirúrgico, levando a paciente ao óbito cerca de seis meses após o diagnóstico.

Locally Confined Primary Signet Ring Cell Carcinoma of the Prostate with Immunohistochemical Analysis.

A case of locally confined primary signet ring cell carcinoma of the prostate in an 85 years old male with complaints of retention of urine, dysuria and frequent nocturia is reported. On per rectal digital examination, hard nodular prostate of grade 3 enlargement was palpated. Serum prostate specific antigen (PSA) level was 33.7ng/ ml. Chest x-ray and computed tomography of the pelvis was negative for metastatic disease. Hematological and biochemical investigations were within normal limits. Transurethral prostatic biopsy was done and histopathology revealed the diagnosis of poorly differentiated adenocarcinoma. Transurethral resection of prostate (TURP) with bilateral orchidectomy along with radiotherapy was selected as modality of treatment. After histopathological examination of TURP specimen with Haematoxylin and Eosin (H & E) and Periodic acid Schiff (PAS) stain, a diagnosis of primary signet ring cell carcinoma of prostate was given which was confirmed by immunohistochemical analysis.

Adenocarcinoma mucinoso pulmonar con patrón de células en anillo de sello: una entidad infrecuente / Mucinous adenocarcinoma of the lung with signet-ring cell pattern: an infrequent entity

El adenocarcinoma mucinoso de pulmón con patrón de células en anillo de sello es una entidad infrecuente de diagnóstico fácil. Presentamos el caso de un paciente de 55 años con antecedente de cardiopatía isquémica y diagnóstico actual de adenocarcinoma primario pulmonar con patrón de células en anillo de sello. Es necesario descartar un origen primario extrapulmonar, principalmente de localización digestiva. Las técnicas inmunohistoquímicas son de gran utilidad a la hora de establecer diagnósticos diferenciales.

Mucinous adenocarcinoma of the lung with signet-ring cell pattern is an infrequent entity of easy diagnosis. We report the case of a 55 year-old patient with preexisting ischemic heart disease and recent diagnosis of pulmonary adenocarcinoma with signet-ring cell pattern. It is necessary discard a primary extrapulmonar location (digestive tract). Immunohistochemistry is a useful tool in the differential diagnosis.

Peri-ampullary collision tumor - high grade neuroendocrine carcinoma and signet ring cell carcinoma: A case report and review of literature.

We report a case of 50-year-old male with obstructive jaundice diagnosed as peri-ampullary collision tumor comprising of large cell neuroendocrine carcinoma and signet ring cell carcinoma. The association of neuroendocrine (usually carcinoids) and adenocarcinoma is extremely uncommon with only few case reports available in the reported literature.

Primary mucinous adenocarcinoma of the bladder with signet-ring cells: case report

CONTEXT: Primary adenocarcinomas of the bladder are uncommon and usually occur by contiguity with or hematogenic dissemination of other adenocarcinomas such as colorectal, prostate and gynecological tract carcinomas. Mucinous and signet-ring cell histological patterns are even rarer and it is often difficult to morphologically distinguish them from metastatic colorectal adenocarcinoma. CASE REPORT: We present and discuss a rare case of primary mucinous adenocarcinoma of the bladder with signet-ring cells in a 57-year-old male patient. Other primary sites for the tumor had been excluded and, in the absence of digestive tract tumor and for confirmation that it was a primary bladder tumor, an immunohistochemistry study was performed.

CONTEXTO: Adenocarcinomas vesicais primários são incomuns, o habitual é o comprometimento por contigüidade ou via hematogênica de outros adenocarcinomas como colorretal, próstata e trato ginecológico. O padrão histológico correspondente ao mucinoso e com células em anel de sinete é mais raro e, muitas vezes, há dificuldade em distingui-lo morfologicamente do adenocarcinoma colorretal metastático. RELATO DE CASO: Apresentamos e discutimos um caso de adenocarcinama mucinoso com células em anel de sinete primário da bexiga em um paciente masculino, de 57 anos. Foram excluídos outros sítios primários do tumor e, na ausência de tumor do trato digestivo e para confirmação de tumor vesical primário realizou-se estudo imunoistoquímico.

A Case of Gastric Adenocarcinoma Presenting as Meningeal Carcinomatosis

Leptomeningeal carcinomatosis occurs in approximately 5% of patients with cancer. The most common cancers involving the leptomeninges are breast, lung cancer and melanoma. However, gastric adenocarcinoma has been rarely reported with leptomeningeal carcinomatosis. The presenting manifestations are usually headache, visual disturbances and seizures. We report a case of leptomeningeal metastasis that presented as a gastric cancer. A 49-year-old woman was admitted to our hospital with the symptoms of headache and melena for 10 days. The endoscopy showed a thickening of the folds of the stomach compatible with the diagnosis of a Borrman type IV gastric cancer. The biopsy revealed a signet ring cell carcinoma. The MRI of brain showed no abnormal findings; however, the patient complained of an intractable persistent headache, nausea and vomiting on admission day 6. The cytology examination of the cerebrospinal fluid supported the diagnosis of metastatic signet ring cell carcinoma.

A Case of Small Intestinal Signet Ring Cell Carcinoma in Crohn's Disease / 대한소화기학회지

Crohn's disease and ulcerative colitis are well known risk factors of intestinal cancer in relation to the extent and duration of disease. Rarely, small bowel cancer can develop after a longstanding inflammation of Crohn's disease with a relatively higher incidence than the general population. Signet ring cell carcinoma is a rare condition among intestinal cancers, and the diagnosis or detection is more difficult if the cancer originates from the small bowel. We report a case of a 30-year old female in whom signet ring cell carcinoma of ileum was diagnosed after a 15-year history of Crohn's disease.

Primary duodenal signet-ring cell carcinoma presenting as gastric outlet obstruction

Small bowel tumors occur rarely. We present an unusual case of a 68 year old man with gastric outlet obstruction secondary to a non-ampullary primary duodenal signet ring cell carcinoma. A review of the literature of small bowel malignant tumors is presented along with the case.

Primary signet ring carcinoma of the large bowel--a case report.

Primary signet ring carcinoma of the colon and rectum is a rare neoplastic disease. The first case was reported by Laufman and Saphir in 1951. The patients have extensive disease at the time of diagnosis and the prognosis is extremely poor. Thus though difficult early diagnosis and curative operation are important.

Adenocarcinoide o carcinoide de células en anillo de sello del apéndice cecal / Adenocarcinoid or signet ring cells carcinoid of the appendix

El adenocarcinoide apendicular es una neoplasia rara que comparte características histológicas del carcinoide y del adenocarcinoma. Su diagnóstico rara vez se realiza antes de la cirugía. Se origina a partir de células totipotenciales de las criptas del intestinos, siendo su comportamiento más agresivo que el carcinoide apendicular típico. Se presentan dos pacientes con diagnósticos de adenocarcinoide apendicular atendidos en el Servicio de Cirugía del Hospital Militar en los años 1995 y 1998. Se analiza su presentación clínica. su estudio posterior y resolución definitiva que consistió, en ambos casos, en hemicolectomía derecha, uno de ellos por videolaparoscopia

Tumor de Krukenberg associado a virilização durante a gestação: relato de um caso e revisão da literatura / Krukenberg tumor and virilization in pregnancy: report of a case and review of the literature

O tumor de Krukenberg (TK) é uma entidade rara, caracterizada por neoplasia ovariana secundária a um tumor do trato gastrointestinal, freqüentemente bilateral, volumoso e assintomático. Afeta geralmente mulheres na quarta década de vida, correspondendo a 1 por cento-5 porcento de todos os tumores ovarianos. Histologicamente são caracterizados por células neoplásicas em anel de sinete, com proliferação estromal não neoplásica e reativa. Poucos casos de TK funcionante são relatados, sendo a associação com virilização durante a gravidez rara. Os autores relatam o caso de uma paciente do sexo feminino, 35 anos de idade, que no segundo trimestre de gestação iniciou com hirsutismo, acne, voz grave e hipertensão arterial sistêmica. A ecografia pré-natal evidenciou volumoso tumor em ovário esquerdo. Foi submetida a cesariana, com nascimento de recém-nato masculino normal. Na evolução, a laparotomia para excisão do tumor em ovário esquerdo revelou carcinomatose peritoneal, metástase hepática e lesão infiltrativa em pequena curvatura gástrica. Exame histológico do tumor ovariano demonstrou adenocarcinoma pouco diferenciado, tipo anel de sinete. A biópsia da lesão gástrica também revelou adenocarcinoma pouco diferenciado, tipo anel de sinete. Foi conduzida com quimioterapia e radioterapia, sem resposta. Evoluiu a óbito oito meses após o diagnóstico.
