Sister Joseph nodule is a metastatic umbilical lesion secondary to a primary malignancy of any viscera. It can be a presenting symptom (a sign of undiagnosed malignancy) or a symptom or sign of progression or recurrence in a known case. Its incidence is 1–3% of all intra-abdominal or pelvic malignancies. Here, we present 4 such cases, with Sister Joseph nodule as a finding of (1) presentation in a case of gallbladder carcinoma, (2) progression in a case of malignant gastrointestinal stromal tumour, (3) recurrence in a case of ovarian carcinoma, and (4) presentation in a case of rectal carcinoma. The clinicopathologic features of all 4 patients are discussed, and the related literature is briefly reviewed.

Introduction: High resolution ultrasound is the most sensitive imaging test available for the examination of the thyroid gland and due to increase in use of ultrasound more incidental thyroid nodules are diagnosed. In this study we try to establish the specific grayscale, color and spectral Doppler characteristics of malignant and benign thyroid nodules. Aim:To determine the specific gray scale characteristics, angio architecture and cutoff values of Doppler indices of malignant and benign thyroid nodules. To assess the efficacy of grayscale, Doppler and combined conventional and Doppler using defined criteria in differentiating malignant from benign nodules. Materials and Methods:We prospectively examined 194 thyroid nodules which were confirmed on FNAC. Each nodule was described according to size, number, contents, echogenicity, margins, halo, shape, calcification, local infiltration and lymphnode enlargement. Vascularity, RI and PI values of each nodule were assessed on Doppler. Each nodule was characterized as benign, indeterminate or malignant based on grayscale and Doppler characteristics. Cutoff RI and PI values for malignant thyroid nodules were obtained by ROC.
