A young man with soft tissue masses involving both upper extremities (2008: 12a)

Excerpt

He had no other symptoms, such as pain or itching, and his general condition was good without weight loss. He denied having a previous medical history or family history. There was no history of animal contact in recent weeks. A physical examination revealed a soft, movable and non-tender mass on the anteromedial aspect of the distal half of his right upper arm. The skin overlying the mass was normal without redness, focal defect, or thickening. There were a few palpable nodular lesions in the ipsilateral axillary region, suggesting lymphadenopathy. Ultrasonography (US) was performed for preoperative evaluation, and showed a heterogeneous echoic mass on the subcutaneous fat layer along the medial aspect of the right upper arm (Fig. 1). In addition, the multiple lymph nodes in both axillary regions and another superficial soft tissue mass on the left upper arm, which had a very similar but less extensive appearance, were incidentally found on US.
