The Malleable Mesenchyme- Elastofibroma

Abstract

Elastofibroma dorsi is an uncommon, benign, subcutaneous, poorly circumscribed, nodular, preponderantly subscapular soft tissue neoplasm representing as a pseudo-tumour or a tumour-like lesion. The neoplasm is essentially composed of collagen and coarse, enlarged elastic fibres. Additionally, nomenclated as elastofibroma dorsi, the tumefaction can be contemplated as a reactive, mesenchymal hyperplasia with aberrant elastogenesis. Elastofibroma characteristically demonstrates elastic fibres intermixed with collagenous stroma and mature adipose tissue. Jarvi et al. [1] initially described the neoplasm in 1959 at the 12th congress of Scandinavian Pathologists. The condition was subsequently published in 1961 [1]. With anomalous imaging manifestations or doubtful tumour discernment, close monitoring, pertinent imaging or evaluation of cogent tissue specimen is recommended.
