Xantelasma: relato de um caso
Miranda, André Henrique;Yamashita, Seizo;Mantoanelli, Daniel;
Radiologia Brasileira , 2001, DOI: 10.1590/S0100-39842001000200013
Abstract: the authors report a rare case of a 71-year-old male patient with a 9-year history of appearance of a "little node" in the right superior eyelid, which increased significantly in size in the last year. computed tomography showed thickening of the lateral rectus muscle and adjacent soft tissues. the diagnosis after biopsy was xanthelasma.
Emprego da tomografia computadorizada na detec??o de altera??es das adrenais em doentes com tuberculose

Radiologia Brasileira , 2004, DOI: 10.1590/S0100-39842004000300006
Abstract: we evaluated the adrenals of individuals without tuberculosis (group 1 - g1) and with tuberculosis (group 2 - g2) using computed tomography. the antero-posterior length, the thickness, and the longitudinal length of the adrenals were compared in g1 and g2. the duration of the disease, the occurrence of morphologic abnormalities in g2, the distribution according to sex, age and skin color were also studied. there was difference in the antero-posterior length and thickness of right adrenal between g1 and g2. a higher prevalence of white skin male individuals was observed in g2. there was no association between duration of the disease and the occurrence of morphologic abnormalities in g2. a higher occurrence of adrenal enlargement was observed in g2. the main computed tomography findings in patients with tuberculosis were enlargement of the adrenal without calcification, enlargement of the adrenal with punctiform calcifications, and residual calcification of the adrenal.
Emprego da tomografia computadorizada na detec o de altera es das adrenais em doentes com tuberculose
Yamashita Seizo,Machado Jussara Marcondes,Morceli José
Radiologia Brasileira , 2004,
Abstract: Neste estudo foram avaliadas, por meio de tomografia computadorizada, as adrenais em indivíduos sem tuberculose (grupo 1 - G1) e com tuberculose (grupo 2 - G2). A dimens o antero-posterior, a espessura e o comprimento das adrenais foram comparados no G1 e no G2. Foram também avaliadas a dura o da doen a com a ocorrência de altera o morfológica no G2, e a distribui o segundo o sexo, a idade e a cor da pele no G1 e no G2. Neste estudo houve diferen a nas dimens es antero-posterior e espessura da adrenal direita entre o G1 e o G2. Observou-se maior ocorrência do sexo masculino e de indivíduos de pele branca no G2. N o houve associa o entre a dura o da doen a e a ocorrência de altera o morfológica no G2. Maior ocorrência da altera o morfológica tipo alargamento foi observada no G2. Os principais achados pela tomografia computadorizada, nos pacientes com tuberculose, foram alargamento da adrenal sem calcifica o, alargamento da adrenal com calcifica o puntiforme e calcifica o de aspecto residual da adrenal.
Xantelasma: relato de um caso
Miranda André Henrique,Yamashita Seizo,Mantoanelli Daniel
Radiologia Brasileira , 2001,
Abstract: Os autores relatam um caso raro em paciente do sexo masculino, de 71 anos de idade, com história de surgimento de "carocinho" na pálpebra superior direita há nove anos, que teve aumento importante há um ano. A tomografia computadorizada evidenciou espessamento da musculatura do reto lateral e de partes moles adjacentes. O diagnóstico pela biópsia foi de xantelasma.
Atypical Calcified Ganglioglioma: A Rare Case Report  [PDF]
Seizo Yamashita, Luiz Antonio Resende, Fernanda M. P. Souza, Marco Zanini, Carlos Clayton, André P. Trindade
Advances in Computed Tomography (ACT) , 2014, DOI: 10.4236/act.2014.31002

Considered rare tumors, gangliogliomas account for 0.4% - 0.9% of intracranial neoplasms. The peak of its incidence occurs between 10 and 20 years of age. These tumors are composed of glial and ganglion cells and they are relatively low-grade neoplasms associated with good prognoses. We report a case of an atypical calcified ganglioglioma in an 18-year-old woman with history of four months of stabbing right-sided parietal headache, paroxysmal. On image studies were noted the presence of thick wall calcification in gangliogliomas. Although rare, this atypical ganglioglioma should be included in the differential diagnosis of lesions occurring in this area of the brain.

Bleomycin sensitivity in patients with familial and sporadic polyposis: a pilot study
Sales, Magaly M.;Lucca, Edmundo J. de;Yamashita, Seizo;Saad, Luis Henrique Cury;
Genetics and Molecular Biology , 1999, DOI: 10.1590/S1415-47571999000100004
Abstract: human peripheral blood lymphocytes from 10 patients with familial adenomatous polyposis (fap) showed a significantly higher incidence of chromatid breaks when compared to cells from 10 normal individuals, after exposure to bleomycin (blm) during the g2 phase. however, no significant increase in bleomycin sensitivity was observed in lymphocytes from 10 patients with sporadic adenomatous polyps (ap) vs. 10 normal individuals (p = 0.67). individuals that exhibited an average number of chromatid breaks per cell higher than 0.80 were considered sensitive to the drug. no control showed susceptibility to blm, as compared to 3 out of 20 patients.
Massa paranasal: dacrioestenose congênita? Relato de caso
Shiratori, Claudia Akemi;Schellini, Silvana Artioli;Palhares, Aristides;Schellini, Ricardo de Campos;Yamashita, Seizo;
Arquivos Brasileiros de Oftalmologia , 2004, DOI: 10.1590/S0004-27492004000500027
Abstract: report of a child presenting a paranasal mass, and discussion of the importance of the differential diagnosis. case report: acs, 6 months old, female, presenting a non inflammatory nodulation on the left medial canthus; tearing and redness in the right eye since birth. on examination, there were bilateral lagophthalmos and corneal ulceration and opacity at the right side; on the left medial canthus there was a rounded lesion with a smooth surface, without inflammation, with an approximately 2-cm diameter. on palpation, the lesion was elevated, fibroelastic, non-mobile, painless, and irreductible. tear or discharge reflux was absent on lacrimal pathway compression, milder's test was negative on both sides. dacryocystographic examination showed normal lacrimal drainage of the paranasal sinus system. computadorized tomography revealed a fronto-ethmoidal meningocele. comments: the authors emphasize the importance of the investigation of paranasal masses, in order to apply adequate therapy.
Traumatic subdural hygroma: five cases with changed density and spontaneous resolution
Zanini, Marco Antonio;Resende, Luiz Antonio de Lima;Freitas, Carlos Clayton Macedo de;Yamashita, Seizo;
Arquivos de Neuro-Psiquiatria , 2007, DOI: 10.1590/S0004-282X2007000100015
Abstract: thirty-four consecutive adult patients with subdural traumatic hygroma were analysed for clinical evolution, serial computed tomography scan (ct), and magnetic resonance imaging (mri) over a period of several months. five of the patients presented ct scan and mri evolution data showing increasing density over a period of 11 days to 6 months post trauma. in these five patients, final clinical and ct scan data were benign, with complete spontaneous resolution. descriptions in literature of evolving traumatic subdural hygroma have presented ct scan density modifications changing into chronic subdural hematoma. our patients show another possibility, density transformation, which sometimes show as subdural hematoma in ct scan and mri, but with final evolution where clinical condition and ct scan return to normal.
Condrossarcoma de epiglote: relato de caso e revis?o da literatura
Tagliarini, José V.;Bacchi, Carlos E.;Yamashita, Seizo;Can?ado, Cristiane G.;
Revista Brasileira de Otorrinolaringologia , 2001, DOI: 10.1590/S0034-72992001000500019
Abstract: chondrosarcoma is the most frequent sarcoma of the larynx. it is more prevalent in the cricoid and less prevalent in the other laryngeal cartilages. chondrosarcoma is rarely located in the epiglottis. we reported a case of epiglottis chondrosarcoma that was treated with a supracricoid laryngectomy with cricohyoidopexy.

Revista Brasileira de Otorrinolaringologia , 2001,
Abstract: Condrossarcoma é o sarcoma mais freqüente da laringe. Sua incidência é maior na cartilagem cricóide do que nas outras cartilagens da laringe, sendo raro que ele se origine na epiglote. Relatamos no texto um caso de condrossarcoma originado na epiglote, no qual foi realizada laringectomia subtotal com crico-hioidopexia - e realizamos revis o da literatura.
