Abstract

We present a 60-year-old man with biopsy-proven metastatic squamous cell carcinoma of the right inguinal and external iliac lymph nodes with unknown primary. Hypermetabolic soft tissue masses were identified in bilateral subscapular regions on follow-up positron emission tomography (PET)-computed tomography (CT) after completion of chemoradiation. The right subscapular mass was biopsied under CT guidance, and histopathology showed it to be elastofibroma dorsi. Elastofibroma dorsi is a benign tumor with no malignant potential; due to its ill-defined appearance and tracer uptake on PET-CT, it can be misdiagnosed as soft tissue sarcoma. This report describes the typical location and imaging features of this incidental hypermetabolic mass.

Posttreatment positron emission tomography (PET)–computed tomography (CT) in a 60-year-old man. (a) Axial CT scan at the level of the left atrium shows crescent-shaped soft tissue masses in both subscapular lesions deep to the latissimus dorsi muscles, with the right bigger than the left (white arrows). (b) Axial nonattenuation corrected PET image shows tracer uptake in the bilateral posterolateral chest (black arrows). (c) The fused PET-CT image, in which the area of hypermetabolic activity corresponds to the soft tissue masses (white arrows), shows an SUV max of 2.7 in the right mass and 2.1 in the left.

Limited prone CT images show grid placement for (a) preprocedure planning and (b) subsequent biopsy needle in the right subscapular mass.

(a, b) Hematoxylin and eosin staining of the biopsy specimen shows altered elastin fibers (yellow arrows) and interspersed mature adipose tissue in a fibrous background. (c) Note the characteristic wavy, serrated edges (yellow arrow) and beaded appearance (blue circle) of the elastic fibers. The inset shows a magnified view. (d) Elastin stains show deeply staining branched and unbranched elastin fibers (yellow arrows).
