ABSTRACT

Se presenta el caso de una paciente mujer de 53 años procedente de Piura con un tiempo de enfermedad de 20 meses, caracterizado por dolor en sitio de herida quirúrgica por colecistectomía abierta realizada hace 3 años, asociado a presencia de una masa en dicha zona, posteriormente se absceda y comienza a drenar secreción alimentaria. Los estudios de imágenes revelaron una masa dependiente de colon transverso en contacto con estómago y pared abdominal que presentaba fistulas hacia piel. Dicha masa fue extraída durante la cirugía con resultado anatomopatológico de adenocarcinoma mucinoso de colon. El caso representó un reto diagnóstico para el equipo médico y en vista de las diversas manifestaciones clínicas del cáncer de colon, sugerimos mantenerlo presente como diagnóstico diferencial en cuadros de absceso de pared abdominal y fistulizaciones entéricas.


We present the case of a 53-year-old woman with a time of illness of 20 months, characterized by pain at the site of surgical intervention for opened cholecystectomy 3 years ago, associated with a presence of a mass in said area, with the following abscess formation and fistulization of food content. Imaging studies revealed a mass dependent of the transverse colon, in contact with stomach and abdominal wall and presenting fistulas to the skin. Said mass was extracted during surgery with anatomopathological result of mucinous colon adenocarcinoma. The case represented a diagnostic challenge for the medical team and in view of the variaty of clinical manifestations of colonic cancer, we suggest that it should be consider as a differential diagnosis in cases of abdominal wall abscess and enteric fistulas.

ABSTRACT

Mujer de 42 años de edad, con tres años de enfermedad caracterizada por episodios de tos productiva, fiebre y disnea, tratada con antibióticos por infecciones bronquiales recurrentes que coincidían con episodios de rubor facial, diarreas acuosas, de una a dos veces por mes, de carácter autolimitado. Presentó episodios de hemoptisis leve. Pese a tener frotis negativo para M. tuberculosis, recibió tratamiento por supuesta tuberculosis pleural, en un centro de salud, sin mejoría clínica, por lo que fue hospitalizada. La radiografía de tórax mostró atelectasia del lóbulo medio e inferior derecho. La tomografía evidenció neoproliferación hilio-basal derecha con marcada captación de medio de contraste, linfonodos metastásicos en hilio y mediastino derecho, incluidos los del grupo subcarinal, con atelectasia crónica en lóbulo medio con bronquiectasias cilíndricas. En la primera broncoscopias, en el bronquio intermediario derecho, se observó unalesión polipoide avascularizada, redondeada, cubierta por membrana blanquecina que ocluía el 100% de la luz, muy friable, que sangraba al roce del cepillo. El Papanicolaou del aspirado bronquial reveló citología sugestiva de neoplasia maligna. En la segunda broncoscopia con biopsia, se demostró tumor carcinoide típico, con inmunohistoquímica positiva para panqueratina y cromogranina.


A 42 year-old female with 3-year disease characterized by episodes of productive cough, fever and dyspnea. She was treated with antibiotics for recurrent respiratory infections, coincident with episodes of facial flushing and watery and self-limited diarrhea which occurred 1-2 times monthly. She had mild bouts of hemoptysis. Despite negative smears for M. tuberculosis, she received 4-drug treatment for pleural tuberculosis, in a primary health center, without clinical improvement, so she was hospitalized. X-ray chest film showed atelectasis of right middle and lower lobe. Computed tomography showed right hilum neoproliferation with marked uptake of contrast, hilar and mediastinal lymph node metastasis including subcarinal group, with middle lobe atelectasis and chronic cylindrical bronchiectasis. A first bronchoscopy revealed, in the right intermediate bronchus, an avascularizaded, polypoid lesion, rounded, covered with a white membrane occluding 100% of bronchus lumen, very friable and bleeding to the brush touch, whose Papanicolaou smear revealed a cytology suggestive of malignancy. The second bronchoscopy and biopsy showed a typical carcinoid tumor with positive immunohistochemistry for panqueratine and chromogranin.

ABSTRACT

Mujer de 55 años con dolor lumbar y dificultad para caminar desde hace 18 meses. En los últimos cuatro meses agrega hiporexia, dolor e inmovilidad de miembros inferiores. Internada en un hospital general (2009), recibe tratamiento antituberculoso: 2HRZE/4H2R2 (INH, RFP, PZN y ETH), al habérsele detectado M. tuberculosis en un frotis de sedimento urinario. Ante inefectividad del tratamiento es trasladada al Hospital General Dos de Mayo (HNDM), en 2010, donde mediante resonancia magnética, se demuestra colapso parcial del cuerpo vertebral de L3, tumor en área craneal parietal derecha (plasmocitoma óseo a cadenas ligeras lambda) y múltiples lesiones óseas circulares sistémicas (coin lesions), en tórax, arcos costales, escápula, húmero y ambos fémures. Proteinograma electroforético en suero y en orina de 24 h, con ausencia y presencia de pico monoclonal, respectivamente. Biopsia de hueso: hipoplasia celular con rango de células plasmáticas neoplásicas (3%-6%). Orina: hematíes, 18-20/campo; leucocitos aglutinados; cilindros hialinos y granulosos. Urea, 108 mg/dL; creatinina, 3,6 mg/dL. El paciente desarrolla infección urinaria, hipercalcemia e insuficiencia renal y fallece sin recibir tratamiento.


A 55 year old woman with back pain and difficulty walking for 11/2 year. In the last four months she added hyporexia, lumbar pain and immobility of lower limbs. Admitted to a General Hospital (2009), she received treatment for tuberculosis: 2HRZE/4H2R2 (INH, RFP, PZN and ETH), having been detected M. tuberculosis in a smear of urinary sediment. Before ineffectiveness of treatment she was taken to the General Hospital Dos de Mayo (HNDM), in 2010, where magnetic resonance, showed partial collapse of L3 vertebral body, cranial tumor in right parietal area (lambda light chain bone plasmacytoma) and systemic circular bone injuries (coin lesions) on chest, ribs, scapula, humerus and both femurs. Protein electrophoresis in serum and urine of 24 hours, showed absence and presence of monoclonal spike, respectively. Bone marrow biopsy showed general cell hypoplasia and range of neoplastic plasma cells of 3%-6%. Urine: red blood cell, 18-20 per field, agglutinated leukocytes, hyaline and granular casts. Urea, 108 mg/dL; creatinine, 3,6 mg/dL. The patient develops urinary tract infection, hypercalcemia and renal failure, dying without treatment.

ABSTRACT

La queratosis actínica es una lesión premaligna cuyo riesgo de degeneración neoplásica se calcula en 10 a 20 por ciento, algunos autores han señalado que la presencia de un fondo inflamatorio facilitaría la progresión a cáncer y por lo tanto la alteraciones de genes involucrados en el control del ciclo celular como p53 y bcl-2. Realizamos un trabajo transversal descriptivo en todos los casos diagnosticados como queratosis actínica durante los años 2000 a 2005 y medimos la positividad para p53, mediante técnicas de inmunohistoquímica, en 5 casos con infiltrado inflamatorio leve. El tipo histológico de queratosis actínica mas frecuente fue el atrófico (50 por ciento), se observó elastosis en 46,15 por ciento de la queratosis actínica tipo atrófico y en 25 por ciento de la queratosis tipo hipertrófico, la inmunorreactividad para p53 se encontró en 80 por ciento de los casos con infiltrado inflamatorio severo y en ninguno de los casos con infiltrado inflamatorio leve. Nuestros hallazgos se corresponden con la teoría que sostiene que la respuesta inflamatoria facilitaría alteraciones en le control del ciclo celular que son la base molecular para el posterior desarrollo de una neoplasia.


Actinic keratosis is a premalignant lesion whose risk of malignant degeneration is calculated in 10 to 20%, some authors have pointed out that presence of inflammation is associated with progression of actinic keratosis to carcinoma, and therefore with mutations of genes involved in cellular cycle as p53 and bcl-2. We carried out a descriptive transversal study in all cases of actinic keratosis whose diagnosis was made in Hospital Dos de Mayo during the period 2000-2005, the presence of p53 was measured with immunohistochemistry in 5 cases with severe inflammatory response and in 5 cases with mild inflammatory response. Atrophic actinic keratosis was the most frequent type (50%), elastosis was found in 46,5% of atrophic actinic keratosis and in 25% of hypertrophic; 80% of cases with severe inflammatory response showed immunoreactive p53 and none of cases with mild inflammatory were immunoreactive. These findings agree with the theory which maintains that inflammatory response would promote alterations in cell cycle, which is the first step in the development of neoplasia.
