Ectopic Paragonimiasis Presented as Multiple Colonic and Liver Masses

Ectopic paragonimiasis has been diagnosed in many organs such as the mesentery, ovary, pleura, central nervous system, subcutis and very rarely in the liver. However, simultaneous involvement of the colon and liver, which mimics colonic cancer with liver metastasis, is quite unusual, and to our knowledge has never been reported. Our case is a 63 year old woman who visited our hospital because of upper abdominal pain. Radiologically, space occupying lesions were detected in the transverse colon, mesocolon and left hepatic lobe. After the radical presection, they were proved to be an ectopic paragonimiasis forming multiple cavitary parasitic granulomas with Charcot-Leyden crystals and degenerating eggs.

Therapeutic Results of Radiotherapy in Rectal Carcinoma-Comparison of Sandwich Technique Radiotherapy withPostoperative Radiotherapy / 대한치료방사선과학회지

PURPOSE: To evaluate the potential advantage for "sandwich" technique radiotherapy compared to postoperative radiotherapy in respectable rectal cancer. METHODS AND MATERIALS: Between January 1989 and May 1994, 60 patients with respectable rectal cancer were treated at Inje University Seoul and Sanggye Paik Hospital.Fifty one patients were available for analysis : 20 patients were treated with sandwich technique radiotherapy and 31 patients were treated with postoperative radiotherapy. In sandwich technique radiotherapy(RT), patients were treated with preoperative RT 1500 cGy/5fx. followed by immediate curative resection. Patients staged as Astler-Coller B2, C were considered for postoperative RT with 2500-4500 cGy. In postoperative RT, total radiation dose of 4500-6120 cGy, 180 cGy daily at 4-6weeks was delivered. Patients were followed for median period of 25 months. RESULTS: The overall 5-year survival rates for sandwich technique RT group and postoperative RT group were 60% and 71%, respectively(p>0.05). The 5-year disease free survival rates for each group were 63%. There was no difference in local failure rate between two groups(11% versus 7%). Incidence of distant metastasis was 11%(2/20) in the sandwich technique RT group and 20%(6/31) in the postoperative RT group(p>0.05). The frequencies of acute and chronic complications were comparable in both groups. CONCLUSION: The sandwich technique radiotherapy group shows local recurrence and survival similar to those of postoperative RT alone group but reduced distant metastasis compared to postoperative RT group. But long term follow-up and large number of patients is needed to make an any firm conclusion regarding the value of this sandwich technique RT.Key Words : Rectal cancer, Sandwich technique, Radiotherapy
