On examination, she had erythema on the upper eyelid, neck and trunk, facial edema, and Gottron's papules on the fingers (Fig. 1).
Magnetic resonance imaging and pathological findings. (A) T2-weighted images through the proximal thigh. Increased signal intensity was seen in the gluteus, obturator, quadrates femoris, vastus, and gracilis muscles. (B) Microscopic view (H&E, x 100) revealed perifascicular atrophy pattern of biceps muscle.

Magnetic resonance imaging (MRI) of the pelvis showed multifocal high signal areas with enhancement at the gluteus, obturator, quadrates femoris, vastus, and gracilis muscles (Fig. 2A). Muscle biopsy from the biceps muscle revealed a perifascicular atrophy pattern (Fig. 2B).
Computed tomography/positron emission tomography scans. (A) Round hypodense mass, 1.8 cm, at the liver S5. (B) Hypermetabolic lesion in liver right lobe and (C) sigmoid colon cancer with pericolic lymph nodes metastasis.

A computed tomography (CT) scan of the abdomen showed a round hypodense liver mass (Fig. 3A), but chest CT showed no evidence of thoracic metastasis. Positron emission tomography (PET) scans showed sigmoid colon cancer with pericolic lymph node metastasis and a lesion in the right lobe of the liver (Fig. 3B and 3C).
