Colon mucinous adenocarcinoma in childhood: a case report with emphasis on image findings.

Colorectal cancer is extremely rare in children. We report a case of a 12-year-old boy who presented with a five-month history of weight loss and anorexia, associated with vomiting episodes, dizziness, fatigue, and dyspnea. On physical examination, a palpable abdominal mass was noticed on the right hypochondrium and flank. An imaging study was performed, which showed a solid mass on the right colon. The patient underwent incisional surgical biopsy, and subsequent histopathologic analysis revealed a colon mucinous adenocarcinoma.

Aspectos radiológicos torácicos na paracoccidioidomicose / Thoracic radiologic aspects in paracoccidioidomycosis

In this paper the authors analyse 159 radiographs from paracoccidioidomycosis patients seen at the Evandro Chagas Hospital/Fiocruz in the period between January 1960 to December 1988. Twenty four cases (15.09) of association with tuberculosis were observed; one with pneumoconiosis; one with aspergillosis, and two with carcinoma. Twenty cases were excluded from the radiologic analysis: in 8 of these the diagnosis of tuberculosis occurred concomitantly, and in 12 patients, lung fibrosis due to previous treatment for tuberculosis or paracoccidioidomycosis was present in the 139 remaining cases, the radiographic abnormalities encountered were grouped according to the predominance of lesions at the various lung sites, if alveolar or interstitial, according to Magalhães' (1982) classification modified by the authors: infiltrate 55 cases (39.6); mist 28 (20.1); pneumonic 23 (16.6); nodular 16 (11.5); micronodular 10 (7.2), and fibrotic 7 (5.0). In 113 cases it was possible to follow the regression of the pulmonary process radiologically. In 85 (75.2) patients, regression took place within 6 months; in 17 (15.0) cases between 7 and 12 months; in 4 (3.5) between 13 and 24 months, and in 7 (6.1) cases no changes in the radiographic pattern were noted.

Displasia epifisária punctata; relato de caso / Chondrodysplasia punctata; a case report

Os autores fazem uma revisäo da literatura e discutem as duas formas de apresentaçäo da doença. Apresentam um caso e relacionam os aspectos clínicos e radiológicos compatíveis com cada uma das formas (síndrome de Conrad-Hunermann e a forma rizomélica)
