Focal dermal hypoplasia syndrome. An electron microscopical study of the skin lesions. 1982

T Tsuji

An 11-month-old female with focal dermal hypoplasia syndrome is described. Histologically, the skin lesions were characterized by a marked decrease in dermal connective tissue. Ultrastructurally, there were a number of fine filamentous structures measuring 5 to 70 nm within and between the bundles of collagen; most of the dermal fibroblasts of the lesions possessed no remarkably developed rough endoplasmic reticulum and Golgi complex. Multilocular fat cells which are regarded as young fat cells were often seen. It is suggested that this disease may be characterized by a decreased rate of collagen synthesis by fibroblasts and an overgrowth of adipose tissue.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
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
D003094	Collagen	A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of SKIN; CONNECTIVE TISSUE; and the organic substance of bones (BONE AND BONES) and teeth (TOOTH).

D004476	Ectodermal Dysplasia	A group of hereditary disorders involving tissues and structures derived from the embryonic ectoderm. They are characterized by the presence of abnormalities at birth and involvement of both the epidermis and skin appendages. They are generally nonprogressive and diffuse. Various forms exist, including anhidrotic and hidrotic dysplasias, FOCAL DERMAL HYPOPLASIA, and aplasia cutis congenita.

D000273	Adipose Tissue	Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
