Eruptive naevi: report of two cases, with enzyme histochemical, light and electron microscopical findings. 1977

R A Eady, and J J Gilkes, and E W Jones

The cases of two young adults with widespread multiple eruptive naevi are described. In the first patient, more than 100 lesions appeared during a period of 6 months. Young lesions were small flesh-coloured telangiectatic papules; older lesions were larger and verrucose with histological features of cellular naevi. In the second patient, a great number of lentigines developed in the course of 2 years. Light and electron microscopy showed that giant melanosomes were present within the lesions. The plasma level of beta-MSH-like immuno-reactivity was normal.

UI MeSH Term Description Entries
D008297 Male Males
D008544 Melanocytes Mammalian pigment cells that produce MELANINS, pigments found mainly in the EPIDERMIS, but also in the eyes and the hair, by a process called melanogenesis. Coloration can be altered by the number of melanocytes or the amount of pigment produced and stored in the organelles called MELANOSOMES. The large non-mammalian melanin-containing cells are called MELANOPHORES. Melanocyte
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
D009506 Nevus A circumscribed stable malformation of the skin and occasionally of the oral mucosa, which is not due to external causes and therefore presumed to be of hereditary origin. Mole, Skin,Moles, Skin,Skin Mole,Nevi,Skin Moles

D006651 Histocytochemistry Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods. Cytochemistry
