BACKGROUND: Acantholysis can be seen occasionally in the cutanous squamous cell carcinoma(SCC) as a result of degenerative changes of neoplastic cells. OBJECTIVE: This study was done to investigate the keratin attern and a wide range of immunohistochemical features of acantholytic cells of cutaneous SCC. METHODS: Seventeen cases of SCC showed acantholytic cells histoloieally and formalin-fixed, paraf-finembedded biopsy specimens from them were stained by ABC(avidin-biotin-peroxidase complex) staining. Fourteen biopsy specimens from 14 cases of SCC were staincd with 3 monoclonal anti-keratin antibodies(CAM 5.2, MAK-6, and 34bE12) and 17 biopsy spec:mcns from 17 cases of SCC were stained with antibodies agairist CEA(carcinoembryonic antigen), vitamin, S-100 protein, Factor VIII-R Ag, LCA(leukocyte common antigen), and lysozyme. RESULT & CONCLUSION: Acantholytic cells of 14 cases of SCC showed consistently negative staining with CAM 5.2. The acatholytic cells showed a wide range of reactivity with MAK-6 from negative to moderately strong positivity and with 34pE12 from negative to strong positivity. A few acantholytic cells of 6 cases of SCC showed weakly positive staining with anti-CEA antibody, but acantholytic cells of all 17 cases showed consistently negative staining wit,h the other antibodies.

Background and OBJECTIVE: There has been a few case reports of anaphylaxis due to honeybee in Korea. In order to observe the clinical feature of bee sting anaphylaxis. Moderials and methods: Six patients living in Kyunggi province area were referred under history of anaphylaxis after the bee sting. Atopy was defined by skin prick test result to common inhalant allergen. Serum specific IgE antibody to each bee antigen was detected by radioimmunoassay to identify the causative bee. RESULTS: All six cases were female. Three had atopy and four had combined allergic diseases such as allergic rhinitis, asthma, and urticaria. The etiologic bees consisted of yellow jacket (6 cases), paper wasp (4 cases), yellow hornet (3 cases), white faced hornet (1 case) and honey bee (1 case). Four cases had experienced anaphylaxis after ant bite and they showed positive result on specific IgE to imported fire ant. Specific immunotherapy against causative bee venom was begun using bee venom extracts from Bayer (USA) based upon results of specific IgE anti-body to bee venom. CONCLUSION: The yellow jacket is the most common cause of bee venom anaphylaxis in this area. Further studies will be needed to evaluate possible cross-reactivity between bee and ant venom.

Lupus erythematosus panniculitis is a rare variant of lupus erythematosus primarily involving a panniculus with or without discoid lupus erythematosus in the overlying skin. A 34-year-old woman showed multiple, variable-sized, indurated subcutaneous nodules on both her upper arms and axillae. A Histopathological examination revealed lobular panniculitis with infiltration of several hyperchromatic atypical large lymphocytes. The infiltrated cells were positively stained with LCA, UCHL-1, CD4, CD8, but not with CD20 and CD68. A T cell receptor -chain gene and immunoglobulin heavy chain gene rearrangement study showed no monoclonality. The result of an ANA test was positive at 1: 40 in a homogeneous pattern. Skin lesions were improved by combined therapy with daily hydroxychloroquine 400mg and prednisolone 10mg in a week and after 6weeks, resolved with atrophic depressed scars. After 4 months, she complained of symptoms of the Raynaud phenomenon and was managed by nifedipine. There has been no recurrence during follow-up for 7 months.
