Desmoid tumor of posterior cruciate ligament of the knee: a case report.

Ling W, Kedong S, Hong W, Weiguo Z, Decheng L - BMC Musculoskelet Disord (2013)

Bottom Line: A 49-year-old man presented with a 2-month history of posteromedial knee dull pain and decreased range of motion of the knee.At present there is no definite and effective method of treatment.In our case, we followed-up the patient five years postoperatively by MRI and got a good result.

ABSTRACT

Background: Desmoid tumor is a rare type of cancer that develops in the tissues that form tendons and ligaments. These tumors, also called aggressive fibromatosis, are considered benign with no metastatic potential. They may invade nearby tissues and organs, however, and can be difficult to control. Desmoid tumor in the posterior cruciate ligament (PCL) of the knee has never been described in the literature.

Case presentation: A 49-year-old man presented with a 2-month history of posteromedial knee dull pain and decreased range of motion of the knee. He was diagnosed desmoid tumor of posterior cruciate ligament of the knee by intraoperative biopsy, and underwent successful PCL resection and reconstruction by Four-strand semitendinosus and gracilis tendon autograft arthroscopically, and fortunately five years after operation, there were no clues as to recurrence of the tumor examined by Magnetic Resonance Imaging (MRI).

Conclusion: Desmoid tumor is characterized by infiltrative growth and a tendency towards recurrence,as this tumor entity is rare, data giving evidence based recommendations for the optimal treatment algorithm for this disease is lacking. At present there is no definite and effective method of treatment. However, early detection of the tumor play an important role, MRI is now the most important method for the detection of tumor extent, which facilitates the treatment choice as well as the prediction of prognosis. In our case, we followed-up the patient five years postoperatively by MRI and got a good result.

Figure 4: The PCL appeared wider and grayer than normal on gross examination, and it was tough and inelastic.

Mentions: Firstly, diagnostic arthroscopy was performed. The posterior cruciate ligament appeared wider and grayer than normal on gross examination, and it was tough and inelastic (Figure 4). Intraoperative frozen histology showed a uniform proliferation of spindle cells with a moderate amount of collagen fibers led to a diagnosis of desmoid tumor in the PCL (Figure 5). Then the PCL was completely resected by clipper bit by bit, and the remaining part of the starting and ending points of the tendon were cleared off by plane iron and low temperature radiofrequency ablation. After that it was reconstructed by Four-strand semitendinosus and gracilis tendon autograft arthroscopically directly after the intraoperative histology and resection. Endobuttons were used to fix the ends of the transplanted ligment. No adjuvant treatment was given postoperatively.
