BACKGROUND: The principle of Mohs micrographic surgery is to examine microscopically the entire peripheral margin of an excised tissue specimen to precisely localize the site of any residual tumor and enable its subsequent removal. In processing in the tissue for frozen horizontal sections, a technical difficulty arises in manipulating the deep and lateral margins into the same flat plane. OBJECTIVE: Our aim was to develop a new method allowing the optimal tissue preperation for Mohs micrographic smgery and to evaluate the usefulness of this methad. METHODS: The technique involves conversion of a non-planar surgical margin to a planar surface by applying and freezing the specimen against a flat glass surface. We compared this modified method used in our laboratory with standard methods for tissue preparation of Mohs micrographic surgery.

Penicillin is still the first choice of drug in the treatment of gonorrhea. The ever lowering sensitivity of Neisseria gonorrhoeae to penicillin and the emergence of PPNG (Penicillinase Producing Neisseria Gonorrhoeae) in the Far East and other parts of the world neceessitate reapprisal of treatrnent schedules with penicillin for gonococcal infections. In Korea, no authentical study in this regard has been done recently. The presence of intracellular gram r.egative diplococci in urethral smear as weIl as the presence of oxidase positive typical, round, convex, smooth, glistening, tratmslucent, greyish colonies of 0.5 to 2mm in diameter a 24 hours composed of grarn negative diplococci are used for presump'ive evidence of gonococccal infection 224 male patients with acnte uncomplicated gonococal infections were treated one of following regimens. Regimen A: 4.8mega unit combicillin (3.6mega unit procaine penicillin+l.2 mega unit sodium penicillin) i.m.. preceded by 1gm probenecid p.o., Regirnen B: 4.8 mega unit procaine penicillin i.m. preceded by 1gm probenecid P.O. Regimen A showed 14 failures(11.3% arnong 124. Regimen B showed 19 failures (19%) among 100 It is suggested that in Korea sesnsitivity to penicillin of Yeisseria gonorrhoeae is quite low.

We report one case of 1 month old male with early congenital syphilis Who represented the characteristic clinical features and laboratory findings including darkfield examindtion and quantitative VDRL test. The histopathologic findings of the patients skin biopsy specimen showed extravasation of erythrocytes and perivascular infiltration of plasma cells were found. in addition to the previous described findings by Fraser. He was managed by daily injection of 200,000 units of aqueous procaine penicillin for 8 days and then three injections of 150,000 units of PA.M at two days intervals with excellent effect

A total of 42 cases undifferentiated large cell tumors were stained by immunoperoxidase techniques using antibodies against leukocyte common antigen (LCA) and epithelial membrane antigen (EMA). In 18 of the 21 cases studied, initially diagnosed as malignant lymphoma or Hodgkin's disease, reactivity with monoclonal anti-LCA (and noreactivity with monoclonal anti-EMA)indicated that the tumor was a lymphomas. The remaining 3 cases gave the reverse reaction pattern and therefore were classified as carcinoma. One out of 16 cases diagnosed as undifferentiated carcinoma proved to be a case of mialignant lymphoma in 5 patients in whom the original diagnosis was uncertain, a definite diagnosis was possible in all cases and 3 of these proved to be large cell lymphoma; the remainders, undifferentiated carcinoma. It is suggested that the staining of undifferentiated human neoplasms using combinations of antibodies reactive with epithelial and lymphoid cells may result in much greater diagnostic accuracy.
