ABSTRACT
BACKGROUND: A number of cases of non Hodgkin's lymphoma of the appendix have been described, but Hodgkin's lymphoma is extremely rare. To our knowledge there are only two reports up to 1966 and none since then. METHOD: We report a case of a 65-year-old gentleman who was treated for suspected Crohn's disease. He failed to respond to medical treatment and underwent right haemicolectomy. The resected segment of bowel demonstrated classical Hodgkin's disease originating in the appendix. He recovered well from the operation and responded well to postoperative chemotherapy. CONCLUSION: Hodgkin's lymphoma of appendix is extremely rare. This case demonstrates the significance of repeated clinical evaluation of patients particularly in the absence of expected response to therapy.

Reports of echogenicity of the fetal lung as it relates to maturity of that organ are scant and at variance. A study was undertaken to determine if any correlation between fetal age and/or lung maturity and echogenicity could be determined in a clinical setting. Studies were performed with either linear array or mechanical sector real-time devices. Echogenicity of the fetal lung was compared with that of the fetal liver in the same longitudinal (parasagittal or coronal) sonogram. Lung echogenicity was judged to be hypodense, isodense, slightly hyperdense, or markedly hyperdense as compared with the liver texture. One hundred eighty-five studies were evaluated; of these, some 37 patients also underwent amniocentesis for determination of lecithin/sphingomyelin ratios (L/S) and presence of phosphatidyl glycerol (PG). Linear regression analyses were performed to determine if lung echogenicity would serve as an indicator of fetal maturity. No clinically applicable relation was established between fetal lung echogenicity and gestational age, L/S, or presence of PG in amniotic fluid with current methodology. The possibility persists that tissue characterization techniques may find application in such an investigation.

A total of 53 consecutive patients who were candidates for surgical treatment of prostatic cancer underwent preoperative evaluation of the lymph node status by computerized tomography scanning and/or lymphangiography combined with skinny needle aspiration biopsy of any abnormal lymph nodes. In 7 of 14 patients (50 per cent) ultimately found to have stage D1 disease lymphatic metastases were confirmed histologically with needle biopsy alone, thus, obviating the need for pelvic lymph node dissection. Over-all sensitivity, specificity and accuracy rates were 50, 100 and 91.4 per cent, respectively, for computerized tomography scanning with biopsy and 53.8, 100 and 84.1 per cent, respectively, for lymphangiography with biopsy. Computerized tomography scanning and lymphangiography with aspiration biopsy are cost-effective means to identify approximately 50 per cent of the patients who ultimately have lymphatic metastases.

We report a large solitary plasmacytoma arising in the sternum of a 62-year-old man. On computed tomography the tumor demonstrated a multilobular appearance associated with bone destruction and expansion and absence of intrinsic calcification. Computed tomography was helpful in determining the size and extent of the tumor and in suggesting the correct diagnosis.
