Childhood pulmonary blastoma: a pleuropulmonary variant of the adult-type pulmonary blastoma. 1991

Two fatal childhood cases of the rare pulmonary blastoma are reported. One was associated with a congenital cystic adenomatoid malformation. Both neoplasms extended to involve visceral pleura and were entirely composed of blastemal and mesenchymal elements without recognizable neoplastic epithelial components. The mesenchymal component in both instances consisted of malignant rhabdomyoblasts, undifferentiated mesenchyme, and differentiated, apparently benign, cartilage. Review of the literature suggests that these features may be specific for the childhood forms of pulmonary blastoma. It is further suggested that pulmonary blastoma, malignant mesenchymoma of the lung, and primary pulmonary rhabdomyosarcoma may have a common pathogenetic origin.

D007633	Keratins	A class of fibrous proteins or scleroproteins that represents the principal constituent of EPIDERMIS; HAIR; NAILS; horny tissues, and the organic matrix of tooth ENAMEL. Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.

D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D009211	Myoglobin	A conjugated protein which is the oxygen-transporting pigment of muscle. It is made up of one globin polypeptide chain and one heme group.
D009418	S100 Proteins	A family of highly acidic calcium-binding proteins found in large concentration in the brain and believed to be glial in origin. They are also found in other organs in the body. They have in common the EF-hand motif (EF HAND MOTIFS) found on a number of calcium binding proteins. The name of this family derives from the property of being soluble in a 100% saturated ammonium sulfate solution.

D010751	Phosphopyruvate Hydratase	A hydro-lyase that catalyzes the dehydration of 2-phosphoglycerate to form PHOSPHOENOLPYRUVATE.
