RESUMO
This report describes a neonate with dermal hematopoiesis associated with diffuse hemangiomatosis. The cutaneous lesions consisted of multiple red papules and bluish subcutaneous nodules scattered over his body. The nodules were bluish due to the presence of hematopoietic tissue within the hemangiomas. Although neonatal dermal hematopoiesis has been described with viral infections or hematologic dyscrasias, the association with diffuse hemangiomatosis has not been previously described.

This report describes a chromosomal abnormality in an 8-year-old boy with renal adenocarcinoma. All tumor cells had the karyotype 46,XY, t(X;17)(p11.2;q25). This karyotype is compared with the cytogenetic descriptions of renal cell adenocarcinoma in two other pediatric patients and in adults.

The role of computed tomography (CT) in the evaluation of the gluteal region was assessed. Six cases of gluteal masses were studied preoperatively by CT; several were also studied with conventional radiographic methods, including barium enema, cystogram, and intravenous urogram. Our case material included an epithelioid sarcoma, Ewing's sarcoma, endodermal sinus tumor, cystic hygroma, neurofibromatosis, and a normal variant. The conventional radiologic studies were normal or demonstrated nonspecific soft tissue density mass effect. By comparison, CT, with its cross-sectional imaging capability, provided unique diagnostic information. CT depicted the presence and origin of a mass, provided tissue characterization, and showed the extent of the lesion, often demonstrating the gluteal mass as an extension of an intrapelvic lesion. CT was valuable in monitoring tumor response to therapy, detecting recurrences, and excluding normal variants as the cause for a gluteal mass. The information provided by CT was important in treatment planning.
