Abstract

Soft-tissue chondroma is rare a benign soft-tissue tumor that occurs mainly in hands and feet. There have been no reports of a chondroma in the supraspinatus tendon. We describe the clinical, histological and radiological features of the intratendinous chondroma of the supraspinatus occurring in a 30-year-old man who was managed arthroscopically and a review of the relevant literature review.

Figure

• 

  Figure 1 The right shoulder AP radiograph shows no definite abnormalities.

• 

  Figure 2 (A) The right shoulder T1-weighted MR sagital image shows well-marginated ovoid mass in the supraspinatus tendon. (B) Dot shaped high signal intensity within ovoid mass and vertical high signal intesity in the biceps anchor are noted on T2-weighted MR sagital image.

• 

  Figure 3 Articular side of the supraspinatus looks slightly elevated but grossly normal appearance.

• 

  Figure 4 (A) Arthroscopically, anterior type of SLAP II lesion was confirmed by probing. (B) Torn biceps anchor was repaired with suture anchors.

• 

  Figure 5 (A) In the bursal side, intratendinous mass in the supraspinatus was exposed by longitudinal incision. (B) Dead space was noted after excision of the mass (C) Defect region was approximated with side-to-side repair using PDS sutures.

• 

  Figure 6 (A) Multiple fragments of the excised mass. (B) Specimen consists of hyaline cartilage arranged with lobular pattern in high power field (hematoxylin and eosin, ×400).

• 

  Figure 7 Postoperative 1 year follow-up MRI shows complete healing of supraspinatus tendon with scarring and there is no evidence of recurrence.
