The occurrence of a fistula between the duodenum and the colon is very rare, although these two structures commonly lie in intimate relationship to each other. It is not uncommon for tumor of the right colon and proximal transverse colon to involve the duodenum by continuity, but fistulous connection between the duodenum and colon are infrequent In most of the reported malignant cases, the fistulas follow carcinomas of the transverse colon or the hepatic flexure of the colon. We report a rare case of malignant duodenocolic fistula which was first suspected by endoscopic examination and confirmed by operation.

Chordoma is a rare distinctively malignant tumor thought to be histogenetically related to the primitive notochord, It is locally infiltrative but does not metastasize until late. The usual initial symptom is pain or some symptom caused by involvement of the nervous system. Involed in the order of frequency are the sacro-coccygeal area, the spheno-occipital area, and the other vertebral area. This case is a sacro-coccygeal chordoma that is confirmed by histologic examination. The lesion was treated by complete excision.

Authors have quantitated the T cell and T subsets(T and T cell) in the per- ipheral blood of 16 patients with alopecia areata and 16 normal healthy controls. The results are as follows: 1. The mean values of the T cell in total patient group(54,6+7.9g) and AAP group(5,3. 1+8. 1%) showed staticstially significant decrease when it compared with the mean value of the control group(64.6+3.6%) respectively(p<0.005). In ATU group the mean value of the T cell(53. 1+8. 1%) also showed decreasing tendency in comparison with that of control. The mean values of the T cell in total patient group(30.9+8. 9%) RIld AAP group(3'l. 5+8. %) showed statistically significant decrease when it compared with the mean value of the control group(42,6+8.9%) respectively(p<0. 005). In ATU group the mean value of the T< cell(28. 7+10. 9%) also showed decreasing tende- ncy in comparison with that of control. 3. The mean values of the Tr, cell in total patient group(6. 1+2. 2%) and AAP group(5.9+2.4%) showed staticstially significant decrease when it compared with the mean value of the control group(7.9+1.3%) respectively(p(p pl, pgp p25) In ATU group the mean value of the T cell(6. 7+0. 9%) also showed decreasing tendency in comparison with that of control. 4. The mean values of the T/T ratio showed no significant difference between the patient groups(total, AAP, ATU) and control group, respectively. Above data showed that defect of T cell and T subsets may be associated with the pathogenesis of alopecia areata.

The role of the immune system in pathogenesis of skin cancer has been attracted increasing attention in recent years. Some limited studies and observations suggest that altered immune status may be a factor in the initiation and growth of cutaneous malignancies. Authors experienced a typical case of xeroderma pigmentosum in a 6 year-old girl, who has been suffered from hyper and hypopigmented macules on sun-exposed area, photophobia and also noted eroded lesion on the lower lip. The biopsy finding of the hyperpigmented macule showed that of freckle and the finding of actinic cheilitis was observed from the specimen of eroded 1esion on the lower lip. We performed immunologic test and obtained some evidences of immunologic defect; such as decreased numbers of total T cells, T-suppressor cell and B cell in our patient.
