Implantation of cancer cells from needle biopsy has been reported in a wide range of malignancies. Fine needle aspiration biopsy has become an accepted method for assessment of thyroid nodules. Local reappearance of thyroid cancer from needle track dissemination is a rare complication of thyroid aspiration. A 45-year-old female developed local recurrence of(More)
BACKGROUND After tissue injury caused by trauma or surgery, alterations of hemostasis are observed and there is a risk for postoperative thromboembolic complications. Laparoscopic surgery, by causing limited tissue injury, appears to be associated with a lower risk for thromboembolism than open surgery. We conducted a prospective randomized study in order(More)
OBJECTIVE Endometriosis is defined as functioning endometrial tissue outside the uterine cavity. It occurs in up to 15% of menstruating females and in most cases is located within the pelvis. Endometrial implants, however have been described in soft tissues, particularly in the skin and subjacent tissues of surgical scars, and diagnosis might be(More)
OBJECTIVE Benign and malignant lesions of the breast may have similar appearances on fine-needle aspiration cytology. We report a case of fibroadenoma that was diagnosed as carcinoma by cytology. CASE STUDY Breast fine-needle aspiration biopsy was highly cellular and composed of bland-appearing spindle/columnar cells that could represent either epithelial(More)
AIM Sentinel lymph node (SLN) biopsy has revolutionized lymph node staging in patients with malignant melanoma. Intraoperative evaluation is a new addition to the SLN procedure that allows for a one-step regional lymph node dissection to be performed when the SLN biopsy findings are positive. The discriminatory immunostaining pattern with the S-100 and(More)
BACKGROUND Poland's syndrome, a rare congenital anomaly characterized by a defect of the pectoralis muscles, has been reported in association with lymphoreticular malignancies and some solid tumors. CASE REPORT We report the case of a 53-year-old woman with Poland's syndrome who developed breast cancer in the afflicted ipsilateral hypoplastic breast. FNA(More)
Peritoneal carcinomatosis (PC) is no longer considered as a systemic disease. There is mounting evidence for a local spread theory [1]. Peritoneal tumor implantation occurs due to multiple mechanisms including serosal invasion, leakage of malignant cells through the lymphatics, or as a result of imprudent dissection [2]. The exact extent of the PC can be(More)
