SUMMARYWe report on an adult woman with rare coexistence of acromegaly, pheochromocytoma (PHEO), gastrointestinal stromal tumor (GIST), intestinal polyposis, and thyroid follicular adenoma. At the age of 56, she was diagnosed with acromegaly caused by a pituitary macroadenoma, treated by transsphenoidal surgery, radiotherapy, and octreotide. During routine colonoscopy, multiple polyps were identified as tubular adenomas with high-grade dysplasia on histology. Years later, an abdominal mass of 8.0 x 6.2 cm was detected by routine ultrasound. Surgical exploration revealed an adrenal mass and another tumor adhered to the lesser gastric curvature, which were removed. Pathology confirmed the diagnosis of PHEO and GIST. PHEO immunohistochemistry was negative for GHRH. During follow-up, nodular goiter was found with normal levels of calcitonin and inconclusive cytology. Near-total thyroidectomy was performed, revealing a follicular adenoma. Her family history was negative for all of these tumor types. Genetic analysis for PHEO/paraganglioma genes (SDH A-D, SDHAF2, RET, VHL, TMEM127, and MAX), and pituitary-related genes (AIP, MEN1, and p27) were negative. Though the finding of PHEO and acromegaly with multiple other tumors could be a fortuitous coexistence, we suggest that this case may represent a new variant of MEN syndrome with a de novo germline mutation in a not yet identified gene.

Aos 56 anos, ela foi diagnosticada com acromegalia por um macroadenoma hipofisário, tratado com cirurgia transesfenoidal, radioterapia e octreotide. Uma colonoscopia de rotina detectou múltiplos pólipos, que à histologia eram adenomas tubulares com alto grau de displasia. Anos mais tarde, uma ecografia detectou uma massa abdominal de 8.0 x 6.2 cm, que na exploração cirúrgica era uma lesão adrenal e outro tumor aderido à pequena curvatura gás-trica. A patologia confirmou os diagnósticos de FEO e GIST. A imuno-histoquímica do FEO foi negativa para GHRH. No seguimento, encontrou-se um bócio nodular com níveis normais de calcitonina e citologia inconclusiva. Após tireoidectomia total o diagnóstico histológico foi de adenoma folicular. A história familiar era negativa para todos esses tumores. As análises gené-ticas para genes de síndromes de FEO/paragangliomas (SDH A-D, SDHAF2, RET, VHL, TMEM127 e MAX) e para hipofisárias (AIP, MEN1 e p27) foram todas negativas. Embora a presença de FEO e acromegalia com múltiplos outros tumores possa ser uma coexistência fortuita, acreditamos na possibilidade de uma nova variante de NEM com uma mutação germinativa de novo em um gene ainda não identificado Arq Bras Endocrinol Metab. 2012;56(8):507-12

The pulmonary manifestations of ulcerative colitis (UC) are rare and include inflammation of small and large airways, parenchymal disease and serositis among others. A substantial proportion of patients with inflammatory bowel disease, particularly those with ulcerative colitis presents positive ANCA, most p-ANCA pattern. We present a case of patient with ulcerative colitis, with positive c-ANCA, which progressed to hemoptysis associated with radiological findings consistent with pulmonary vasculitis.

The genus Vibrio is a member of the family Vibrionaceae, and among their disease-causing species, Vibrio vulnificus, a lactose-positive gram-negative bacillus, is one of the most virulent pathogen of the noncholerae vibrios. We describe the case of a 39-year-old male patient, who was using immunosuppressive therapy, admitted to the hospital for liver transplantation. Twelve hours later, the patient presented high fever, myalgia, anuria and erythematous plaques on lower limbs, of rapid growth and proximal progression. The patient was treated with ceftriaxone, meropenem and oxacillin, however he expired within 30 hours. Blood cultures showed growth of a gram-negative bacillus, which was later identified as Vibrio vulnificus.

Systemic lupus erythematosus (SLE) can cause numerous skin lesions. Despite being rare, lupus-specific bullous lesions demonstrate characteristic clinical and immunopathological features and require differential diagnosis among numerous bullous conditions that may overlap with SLE. The present study presents a case of bullous systemic lupus erythematosus (BSLE) in a pregnant woman.

Introdução: O sarcoma de sistema nervoso central (SNC) é uma neoplasia rara, com incidência de 0,1% a 4,3% dos tumores intracranianos. São tumores agressivos com prognóstico reservado e a maioria é tratada com ressecção radical. Relato: Homem, 29 anos, com episódios de crises convulsivas e diagnóstico de hemorragia intraparenquimatosa. Durante a cirurgia, foi identificada lesão bem delimitada. A histologia demonstrou neoplasia fusocelular com atipias e numerosas mitoses. Os únicos marcadores imuno-histoquímicos positivos foram vimentina e S-100. O diagnóstico foi de sarcoma indiferenciado de alto grau. Conclusão: No diagnóstico diferencial de sarcomas de SNC, devem-se excluir lesões metastáticas e gliossarcoma.
