REPORT OF A CASE
A 15-year-old boy was referred for evaluation of six nodules on his upper legs that had appeared 4 to 6 weeks previously. The tumors were between 1.5 and 4 cm in size, tense, subcutaneous, well demarcated, and movable, without any signs of inflammation or infiltration. They were faintly visible through the skin, slightly bluish (Fig 1), and painful to palpation. The patient had been trained as a high-performance swimmer but had taken no drugs. He could not remember any trauma to the area. Clinical and laboratory investigations disclosed no abnormalities. One tumor was removed surgically and the diagnosis was confirmed on histologic examination of the lesion (Fig 2).What is your diagnosis?
The biopsy specimen stained with hematoxylin-eosin and van Gieson stain showed an encapsulated subcutaneous tumor surrounded by normal collagen tissue without accompanying inflammation or infiltration
