Bullous systemic lupus erythematosus in a pregnant woman: a case report.

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.

c-ANCA associated vasculitis in patients with ulcerative colitis: case report.

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.

Lúpus eritematoso sistêmico bolhoso em gestante: relato de caso / Bullous systemic lupus erythematosus in a pregnant woman: a case report

O lúpus eritematoso sistêmico pode apresentar inúmeras lesões cutâneas. As lesões bolhosas específicas do lúpus, apesar de raras, apresentam características clínicas e imunopatológicas próprias e implicam em diagnóstico diferencial entre inúmeras patologias bolhosas que podem sobrepor-se ao lúpus eritematoso sistêmico. Apresenta-se um caso de lúpus eritematoso sistêmico bolhoso em gestante.

Vasculite c-ANCA relacionada em paciente com retocolite ulcerativa: relato de caso / c-ANCA associated vasculitis in patients with ulcerative colitis: case report

As manifestações pulmonares da retocolite ulcerativa (RCU) são raras e incluem inflamação de pequenas e grandes vias aéreas, doença parenquimatosa e serosite, entre outras. Uma proporção substancial de pacientes com doença inflamatória intestinal, particularmente aqueles com RCU, apresenta ANCA positivo, a maioria padrão p-ANCA. Apresentamos um caso de paciente com RCU, com c-ANCA positivo, que evoluiu com hemoptise, associada a alterações radiológicas compatíveis com vasculite pulmonar.

Genetic studies in a coexistence of acromegaly, pheochromocytoma, gastrointestinal stromal tumor (GIST) and thyroid follicular adenoma / Estudos genéticos na coexistência de acromegalia, feocromocitoma, tumor do estroma gastrointestinal (GIST) e adenoma folicular de tireoide

We 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.

Relatamos o caso de uma mulher com rara coexistência de acromegalia, feocromocitoma (FEO), tumor do estroma gastrointestinal (GIST), polipose intestinal e adenoma folicular de tireoide. 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 gástrica. 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 genéticas 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.

Sarcoma indiferenciado primário no sistema nervoso central / Primary undifferentiated sarcoma of the central nervous system

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.

INTRODUCTION: The central nervous system (CNS) sarcoma is a rare neoplasm with an incidence of 0.1% to 4.3% in intracranial tumors. They are aggressive with poor prognosis, and mostly treated with radical resection. REPORT: 29 year-old male patient with episodes of seizures and diagnosed with intraparenchymal hemorrhage. During the surgery a well-defined lesion was identified. Histology showed a spindle cell neoplasm with atypia and numerous mitoses. The immunohistochemical markers were positive only for vimentin and S-100. The diagnosis was high-grade undifferentiated sarcoma. CONCLUSION: Metastatic lesions and gliosarcoma should be excluded in the differential diagnosis of CNS sarcomas.
