Adult T-cell lymphoma (ATLL) is an aggressive neoplasm of T-lymphocytes, usually associated with human T-lymphotropic virus type 1 (HTLV-1). Variegated clinical presentation. Primary gastric lymphomas most frequently have type B non-Hodgkin lymphoma (NH) as an etiology, and a minimal percentage is due to T lymphocytes. Literature on primary gastric lymphomas due to HTLV1 Negative T cells that metastasize to bone is scarce. The case of a 41-year-old adult who was admitted for a pathological fracture is presented. At 15 days he presented diarrhea, abdominal distension. An upper endoscopy finds: "Ulcerated gastric lesions, neoproliferative appearance." Biopsy reported: Non-Hodgkin lymphoma to T lymphocyte. HTLV1: negative. He had 3 sessions of chemotherapy with CHOEP scheme. There was a favorable response, at first. Unfortunately DID NOT RETURN. He returned 2 months later in poor general co...

We present the case of an 84-year old male farmer, who was diagnosed in 2001 with megaloblastic anemia associated to vitamin B12 deficiency, sensory-motor polyneuropathy in his lower limbs and gastric atrophy with intestinal metaplasia. The patient was treated with a combination including 1000 mcg folic acid and 8 mcg cyanocobalamin. He improved his hemoglobin levels back to normal after 2 months of therapy. One year later, he stooped therapy because he was feeling better. In 2008, anemia and the sensorial motor polyneuropathy reappeared, together with an inadequate perception of normal flavor. At this time studies showed the following: pancytopenia, severe megaloblastic anemia, vitamin B12 deficiency, gastric atrophy, gastric polyps and xanthomas, intestinal metaplasia, serum lipid abnormalities, facial xerosis and generalized white spotted macular lesions (2-3 mm). He was treated with ...

Varón de 36 años con diagnóstico de infección VIH-1 por siete años y sin tratamiento que presentó convulsiones generalizadas en los últimos cinco meses y marcada baja de peso. Se le halló hemiparesia izquierda y rigidez de nuca moderada, disartria y un tumor palpable frontoparietal derecho. La tomografía reveló un tumor de 11 x 9 cm en la zona frontal, con edema peritumoral que comprimía los ventrículos laterales y desviaba la línea media en más de 5 mm. La biopsia reveló un linfoma primario difuso, a células B grandes, VEB (+), CD 20 (+), Ki 67:80%. El conteo de CD4 fue 9 células/mm3 y la carga viral VIH fue 54 352 copias/mL. Fue tratado con TARGA, mejorando su condición general y disminuyendo las convulsiones.

Introduction: In our context, there are no studies which had evaluated the markers of bone turnover in postmenopausal women with osteoporosis, considering the high rate of morbidity and mortality associated with fragility fractures. Objective: To know the biochemical features of bone metabolism in women with postmenopausal osteoporosis. Methods: A cross-sectional study. 49 women with postmenopausal osteoporosis were included. Bone mineral density in spine, hip and forearm was measured by dual x-ray absorptiometry. Calcium, phosphorus, osteocalcin, alkaline phosphatase, vitamin D and paratohormone were measured in blood. N-telopeptide of collagen type I, calcium and phosphorus were measured in urine by conventional methods. Results: The average age of the participants was 59,1± 7,5 years. The average time since menopause was 12,0 ± 7,9 years. All ...

This is the story of a 50 year-old male subject with a 7-month illness characterized by myalgia, fatigue, and malaise. 5 months before being admitted to Dos de Mayo National Hospital (HNDM), he developed right pleural effusion requiring pleural drainage (1500-2500 mL/day). While in HNDM, the patient developed bilateral pleural effusion with increased triglycerides. A multiple-slice contrast spiral CT (TEM) of the chest showed mediastinal lymph node enlargement, bilateral pleural effusion, and the presence of fluid within the right posterior mediastinal pleura adjacent to D10-D11-D12, and an osteolytic image in D11 vertebral body. A left axillary lymph node biopsy revealed non- Hodgkin lymphoma (NHL), follicular type with large and small cells. The patient received a diet rich in medium-chain triglycerides and olive oil as a supplement, and he also received chemotherapy (dexamethasone, cy...

We report the case of a 31 year-old male from Cajamarca, Peru, with cognitive problems since childhood, who at 12 year-old developed increased volume and deformation of his right lower limb and to a lesser extent of his left, associated to massive skin folding, growth of subcutaneous nodules, elephantine look due to nerve cords formation in thigh and leg, pain and functional walking limitation. Concomitantly generalized skin café au lait spots, subcutaneous nodules, and Lisch nodules in both irides. Magnetic resonance and contrast TAC revealed abundant uniform plexiform nodules in abdomino-pelvic cavity forming masses and cords that continued throughout his thigh as lumps and cords. In addition, the patient presented bone dysplasia (thinning of femur and tibia cortex, pseudoarthrosis, new left cotyle formation). Contrast magnetic resonance showed triventricular normotensive hydrocephalu...

Objective. To evaluate the importance of bone biopsy in the diagnose of the bone metabolic diseases, its relationship with bone densitometry (BMD) and biomarkers. Methods. In a descriptive, transversal study, 38 biopsies of pelvic bone were made, 36 in female (34 postmenopausal and 2 premenopausal) and 2 in male. All had BMD in spine, hip and/or forearm measured by dual x-ray absorptiometry. Calcium, phosphorus, parathormone, vitamin D, alkaline phosphatase, osteocalcin, hemoglobin, transaminases, total protein and fractions were measured in blood and N-telopeptide of collagen type I, calcium and phosphorus in urine by conventional methods. Results. The mean age of 34 menopausal women was 58 ± 7,79 and menopause time was 11,48 ± 8,76 years; mean BMD in spine, hip and forearm were -2,88 ± 1,16, -2,13 ± 0,82, y - 5,14 ± 1,76, respectively; bone biopsy demonstrated osteoporosis in 33 y...

Varón de 24 años, natural de Lima, que desde hace tres años padece de limitación funcional de los miembros inferiores a predominio izquierdo, dolor abdómino-pélvico crónico, incremento del número y tamaño de manchas dérmicas y nódulos subcutáneos. Al examen físico: presencia de manchas café con leche, nódulos subcutáneos generalizados, pecas en ambas axilas e ingles y nódulos de Lisch en ambos iris. La resonancia magnética nuclear descubrió un incremento del volumen de las raíces y trayectos de los nervios D12-S2, un tumor hipodenso quedesplazaba la cola del páncreas hacia adelante, infiltración tumoral del músculo psoas y hueso iliaco izquierdo; además, un tumor multinodular presacro-coccígeo. La biopsia de un nódulo cervical subcutáneo demostró neurofibromatosis plexiforme benigna. La biopsia del tumor presacro-coccígeo reveló la existencia de un tumor mal...

Se describe las características microbiológicas y anatomopatológicas de una serie de pacientes con bronquiectasias sangrantes que fueron negativos a tuberculosis, HIV y neoplasias, en estudios preliminares. Se desarrolló una evaluación microbiológica y anatomopatológica en búsqueda de hongos, tuberculosis, gérmenes comunes y neoplasia pulmonar, sobre 24 piezas operatorias de pacientes con hemoptisis por bronquiectasias sangrantes con antecedente de tuberculosis pulmonar o de contacto con personas que padecían esa enfermedad. El hongo Aspergillus es el principal y único agente infeccioso presente en los pacientes con bronquiectasia sangrante en este estudio.
