Bilateral Elastofibroma: Report of a case.: Sung Chul Lim, Mi Sook Lee, You Kyung Jeong, Yun Shin Kim, Hyun Jong Park, Mi Ja Lee; Korean J Pathol. 1997;31(6):589-591.

Abstract PDF: Elastofibroma is a rare benign tumor-like condition manifesting as firm and spherical mass with poorly circumscribed margins of fibroelastic tissue, occuring in the subscapular region or the chest wall of elderly persons. It is not a true neoplasm but rather a reactive or degenerative process causing abnormal elastogenesis. It is unilateral in the majority of cases and the right side is affected more commonly than the left. We report a case of bilateral elastofibromas removed from both subscapular regions of a 73-year-old female farmer. She was presented with tender masses on the bilateral subscapular areas for seven years. Microscopically, it consisted of a mixture of intertwining broad eosinophilic collagen bundles and elastic fibers associated with a few fibroblasts and mature fat cells. The elastic fibers had a degenerated beaded appearance or were fragmented into serrated globules in a linear arrangement.

Elastofibromatous Lesion of the Stomach: A case report.: Mee Sook Roh, Sook Hee Hong; Korean J Pathol. 1995;29(1):103-105.

Abstract PDF: Elastofibroma is a peculiar tumor-like lesion which manifests as a slowly growing, solid, ill-defined mass of fibroelastic tissue occurring almost exclusively in elderly persons. It has been found in the ,,ubscapular region but rare examples have also been found in other locations. We experienced a case of elastofibromatous lesion of the stomach. The lesion was incidentally found in a 71 -year-old woman during an operation of cholecystectomy due to chronic cholecystitis and choledocholithiasis. The lesion was a relatively well-defined but not encapsulated small nodule, 0.7 cm in diameter, at submucosal layer of gastric pylorus. Histologically the nodular mass consisted of abundant acellular collagen fibers containing numerous elastofibroma fibers.

Elastofibroma: Report of a case.: Hye Kyung Lee, Kwang Min Lee, Dong Kyu Chung, Eul Sam Chung; Korean J Pathol. 1992;26(6):635-637.

Abstract PDF: Elastofibroma is a rare entity of slowly-growing, solid, ill-defined fibroblastic mass occurring almost exclusively in elderly persons and arising mainly from the connective tissue between the lower portion of the scapula and the chest wall. This entity has been considered to be a degenerative pseudo-neoplastic process caused by mechanical friction. We report an additional case of elastofibroma removed from the subscapular region of a 58-year-old woman. Microscopically the tumor was made up of a mixture of swollen eosinophilic collagen and elastic fibers occasionally associated with fibroblasts and mature fat cells. The elastic fibers showed a degenerated beaded appearance or were fragmented into small globules or droplets in a linear pattern.

Elastofibroma.: Sang Yong Song, In Ae Park, Yong Il Kim; Korean J Pathol. 1992;26(4):420-422.

Abstract PDF: Elastofibroma is a rare benign tumorous growth presenting as a slowly growing ill-defined mass of fibroblastic tissue occurring in elderly persons and arising mainly form the connective tissue between the lower portion of the scapula and the chest wall. Its pathogenesis is not well established but it may be the result of nonneoplastic reactive hyperplasia taking place with constitutional predisposition in the background. A case of elastofibroma occurring in the subscapular area of a 65-year-old female cook is presented. The mass, 6x5x3 cm in maximum dimensions, was poorly circumscribed, solid, hard, pale fleshy and pray-white fibrous tumor. Microscopically, it was composed of numerous small globular and linear elastic fibers embedded in collagenous matrix. To our knowledge, it is the first case of elastofibroma in Korea.
