Identifying the SLN and analyzing tumor involvement can predict the status of the remaining lymph nodes. Sentinel lymph node (SLN) refers to the initial site of the lymphatic drainage from a primary tumor area. However, during the SLN biopsy, blue dyeĪlso was present in the scar.You just subscribed to receive the final version of the article We thought that the hot spot just in the scar might be a false-positive in SPECT. At the time of preoperative scintigraphy, In our case, the postoperative scar was positive in both SPECT and dye tracer. Rokutanda et al also reported a case of false-negative SLN biopsy showing isolated retromammary lymph node metastasis ofīreast cancer without axillary lymph node involvement. Of lymphatics by metastatic melanoma and stressed the value of ultrasound combined with preoperative lymphoscintigraphy. Larn et al reported false-negative SLN biopsy because of obstruction However many pitfalls have been reported. The method is now routinely performed in many Sentinel lymph node biopsy is a standard for staging of malignant melanoma. He was tumor-free one year after the operation. Therapy with low-dose interferon beta and no significant adverse effect occurred. We diagnosed the tumor as pT1bN0M0, stage 1B.

Scar, which also showed no metastasis (Figure 1b). In the distal one, lymph node tissue surrounded the postoperative Histopathology showed no metastasis in the proximal SLN. The distal one was a hard subcutaneous mass, which was clinically compatible During the SLN biopsy procedure, both a handy gamma probe and blue dyeĭetected the same two sites as positive SLNs. Postoperative scar of the previous lymph node biopsy. Showed two hot spots in the left groin and one hot spot in the lesser pelvis (Figure 1a). Preoperative lymphoscintigraphy combined with CT (SPECT) He underwent a SLN biopsy using combined dye-radiotracer technique. He had undergone a lymph node biopsy of the left groin 30 years priorīecause of a suspected lymphoma, which had shown no malignancy and remained as a postoperative scar.

Was no personal or family history of skin malignancies. The pathology showed the tumor thickness was 1.1 mm. The primary tumor was removed at a local hospital. High magnification of the boundary of the scar and lymph node tissue (H&E, x200).Ī 61-year-old Japanese male was referred to our hospital for staging and subsequent therapy for malignant melanoma on the Histopathology of the distal hot spot in SPECT showed a mature scar in the center of the specimen, which was surroundedįigure 1c. The site of a postoperative scar from a lymph node biopsy 30 years prior.įigure 1b. SPECT detected two hot spots in the left groin and one hot spot in the lesser pelvis. Lymph node tissue was detected as a SLN 30 years after lymph node biopsy.įigure 1a. However, many pitfalls on the SLN procedure have been reported. Sentinel lymph node biopsy using combined dye-radiotracer technique improved the detection rate and made the method easier.

Herein, we present a new pitfall.Ī formation of scar and lymph node tissue was detected as a SLN 30 years after lymph node biopsy. Sentinel lymph node biopsy using combined dye-radiotracer technique improved the detection rateĪnd made the method easier. In recent years, sentinel lymph node (SLN) biopsy has been used as a diagnostic and prognostic indicator for a number of tumors, Masami Toya, Miki Tanioka, Hideaki Tanizaki, Akihiro Fujisawa, Yoshiki Miyachi Dermatology Online Journal 18 (1): 13 Department of Dermatology, Kyoto University Graduate School of Medicine, Kyoto, Japan Abstract Another pitfall of sentinel lymph node biopsy: Scar after lymph node biopsy 30 years ago revealed a sentinel lymph node
