Sentinel node mapping in Marjolin's ulcers: is it feasible?

INTRODUCTION: This study evaluated the feasibility of sentinel node biopsy in Marjolin's ulcers using peritumoral injection of the radiotracer and blue dye. MATERIALS AND METHODS: Ten patients with Marjolin's ulcers (5 male and 5 females) ranging in age from 39-65 years, and who were candidates for surgical removal of their tumors, were included in this study. The patients received 2 mCi technetium 99m (99mTc) antimony sulfide colloid in 2 divided doses subcutaneously in the peritumoral region. Immediately after anesthesia induction, 1 cc patent blue V in 2 divided doses was also injected in the same fashion as the radiotracer. Lymphatic mapping and sentinel node biopsy was performed using a gamma probe. Any hot and/or blue lymph nodes were harvested as a sentinel node. Primary lesions were then excised and wounds grafted with a splitthickness skin graft. RESULTS: A sentinel node could be identified on the lymphoscintigraphy images in only 2 patients. Sentinel node mapping was successful during surgery in these 2 patients. None of the harvested sentinel nodes were blue. CONCLUSION: Lymphatic mapping and sentinel node biopsy do not seem feasible in Marjolin's ulcers located in areas of extensive burn scarring due to a low detection rate. Larger studies are needed to validate the results of this study.

Does orientation of full-thickness groin grafts affect hyperpigmentation in burn contracture and syndactyly hands?

BACKGROUND: Some grafts harvested from the groin area do not become hyperpigmented and in an individual with multiple pieces of grafts, the hyperpigmentation of the pieces may vary. This study evaluates the orientation of the inset of groin grafts according to their donor sites (superior-inferior) and its role in graft hyperpigmentation. METHODS: Patients with hand burn contracture or syndactyly who required at least 2 pieces of grafts were enrolled. In each patient, one piece of the graft was inset in the same direction of the orientation of the donor site and the other in the opposite direction. Six months after the operation, the pigmentation was scored by a subjective scaling from 1 to 5. RESULTS: Thirty-four fingers of 15 patients were included. The mean grade of pigmentation in grafts inset in the direction of the donor site was 3.00±1.118 and in those inset in the opposite direction was 2.88±1.409. This was not statistically significant. CONCLUSION: Our findings revealed that although the grafts inset in the opposite direction of the donor site, they were less pigmented. So orientation of full thickness groin grafts did not affect hyperpigmentation of the grafts in burn contracture and syndactyly hands.

Chronic Low Back Pain due to Retroperitoneal Cystic Lymphangioma.

Abdominal cystic lymphangioma is a rare benign neoplasm. Less than 1% of lymphangiomas is in the retroperitoneum. Lymphangioma is mostly asymptomatic. Chronic symptoms were reported in retroperitoneal type more than others. Acute symptoms due to complications like infection, cyst rupture or hemorrhage may occur. We report an 18-years-old girl with low back pain from 6 months ago with huge pelvic mass and diagnosis of retroperitoneal cystic lymphangioma.

Accuracy of prognostic and predictive markers in core needle breast biopsies compared with excisional specimens.

BACKGROUND: Core needle biopsy (CNB) is widely accepted for preoperative diagnosis of breast cancer and sometimes can be the only way of providing a suitable specimen for prognostic and predictive marker studies prior to neoadjuvant treatment. The purpose of this study was to evaluate the accuracy of CNB by comparing histological tumor type and grade as well as estrogen receptor (ER), progesterone receptor (PR), p53, and HER2/ neu status by immunohistochemistry in CNB and excisional surgical specimens. PATIENTS AND METHODS: During a 2.5-year study period, we identified 30 patients with breast cancer, who underwent CNB and definitive surgery. To evaluate the accuracy of CNB, tumor grade, ER, PR, HER2, and p53 status were immunohistochemically determined in both the CNB and the surgical specimens, and concordance of results between the 2 specimens was assessed. RESULTS: The concordance rate was 100% for histological type, 66.6% for histological grade, and 96.7, 90, 76.7 and 93.3% for ER, PR, p53 and HER2/neu, respectively. CONCLUSION: Our study showed that CNB has an excellent accuracy for tumor type, ER, and HER2/ neu; however, it should be used cautiously for tumor grade, PR, and p53 status. Thus, excisional biopsy is recommended for the determination of these factors.
