Another histological variant of basal cell carcinoma (BCC) is described. This clear-cell variant appeared as a recurrent lesion on the back of an elderly man. Histological examination revealed that part of the tumor was composed of clear cells with faintly eosinophilic cytoplasm. Degenerative changes were present, along with calcium deposition. Mucin was present within the stroma and within the degenerative areas of the tumor. Staining with anti-S-100, anti-keratin, and anti-carcinoembryonic antigen antibodies was negative. Electron microscopy demonstrated epithelium-derived cells with marked phagolysosomal accumulation within the cytoplasm. We conclude that this clear-cell variant is due to degenerative change within a BCC.

D008297	Male		Males
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
D009336	Necrosis	The death of cells in an organ or tissue due to disease, injury or failure of the blood supply.
D002114	Calcinosis	Pathologic deposition of calcium salts in tissues.	Calcification, Pathologic,Calcinosis, Tumoral,Microcalcification,Microcalcinosis,Pathologic Calcification,Calcinoses,Calcinoses, Tumoral,Microcalcifications,Microcalcinoses,Tumoral Calcinoses,Tumoral Calcinosis
D002280	Carcinoma, Basal Cell	A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs.
