Internal mammary sentinel node biopsy for breast cancer: is it practicable and relevant? (Review).
Sentinel lymph node (SLN) biopsy is a useful way of assessing axillary nodal status and obviates unnecessary axillary lymph node dissection for patients with node-negative breast cancer. However, SLN can also be located in the internal mammary lymph node (IMN) chain or elsewhere. The practicability and relevance of internal mammary SLN is reviewed and discussed. ⋯ However, the reported incidence of positive internal mammary SLNs is still lower than expected, because the spread of radioisotope activity is not synonymous with nodal positivity. Internal mammary SLN biopsy is considered to be still in the investigative stage. More data are needed on the correction of a internal mammary SLN and pathologic positivity, so that further clinical investigation is clearly warranted.

Giant cell tumor of the tendon sheath (GCTTS), tenosynovial giant cell tumor (TGCT), and pigmented villo-nodular synovitis (PVNS) are the common names for a group of rare proliferative disorders that involve synovial joints and tendon sheaths. Considerable confusion exists about the surgical treatment and diagnosis of these disorders. This review evaluates the presentation, surgical therapy and recurrence of these three proliferative disorders. ⋯ If diffuse, complete synovectomy is indicated for disease confined to the joint, and resection of all gross disease is indicated for extra-articular disease. Radical resection with negative margins is not necessary in most instances. In rare aggressive cases, local recurrence may necessitate more extensive resection and radiation therapy.
