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.

PURPOSE: To report a single case of herpes simplex keratitis after application of 0.015% tafluprost eye drops. CASE SUMMARY: A 68-year-old male presented with left eye discomfort, epiphora, decreased visual acuity and hyperemia. The patient was diagnosed with glaucoma 6 weeks prior and started on 0.015% tafluprost eye drops in left eye and 0.15% brimonidine in both eyes. On slit lamp examination dendritic epithelial defect was observed and the patient was diagnosed with herpes simplex keratitis. The 0.015% tafluprost treatment was discontinued and 0.15% brimonidine was applied in both eyes twice a day. The herpetic keratitis in his left eye resolved completely in 2 weeks with acyclovir ointment and oral antiviral agent. No further recurrence was observed in the following 3 months.

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.
