Primary cutaneous monomorphous lymphoma is rare compared to the more usual involvement of skin secondary to internal monomorphous lymphoma. The histopathological diagnosis of the primary cutaneous monomorphous lymbhoma (PCML) requires differentiation from cutaneous lymphoid hyperplasia. The authors observed 3 cases of PCML. Case 1 was 21 year-old woman, who had an initial lesion on her left arm. Histopathologically it was diagnosed as poorly differentiated. lymphocytic lymphoma and was treated by surgical excision. Six months after onset she developed new lesions on her skin elsewhere, histopathologically diagnosed as well differentiated lymphocytic lymphoma. She died of infiltration of the bone marrow 19 months after the initial onset, even though combination of radiotherapy and chemotherapy resulted in clinical improvernent. Case 2 was a 70 year-old woman having an unusual cutaneous manifestation of an adult palm sized ulcerative, indurated tumor on her right forearm, histopathologically diagnosed as histiocytic lymphoma. There was no evidence of extracutaneous in volvement except right axillary lymphadenopathy. Case 3 was 72 year-old man, who had a clinical manifestation to that of case 2, histopathologically diagnosed as histiocytic lymphoma and received radiotherapy with good improvement. The patient did not show any evidence of extracutaneous involvement five months after the onset.

Papulonecrotic tuberculid (PNT) and Pityriasis lichenoides et varioliformis acuta (PLEVA) have been in controversy in their pathogeneses and entity itselves. Authors reviewed litera,tures of the two dermatoses with observation of nine casea of PNT from 1979 to 1981 and evaluated whether PNT could be also classified as PLEVA. The results were a,s follows: 1. By the review of literatures PNT and PLEVA showed great similarities in their clinical aspects including shape of cutaneous lesions, course, favorite age and subjecive symptoms. Histopathological overlappings were also found. 2. Of the nine cases of PNT authors observed, seven cases were histopathologically PLEVA and four cases could be thought PLEVA also clinically. But way six cases were treated by anti-tuberculous drugs. 3. The incidence of other tuberculous signs and results of tuberculin skin tests were all significant in the nine cases above. With the above observations it seems that PNT is one of the causes of PLEVA and thus could be a kind of PLEVA.

We herein present a case of simultaneous occurrence of apocrine adenocarcinoma, syringocystadenoma papilliferum, syringoma, and eccrine hydrocystoma arising in an organoid nevus (nevus sebaceus of Jadassohn) which had been present on the right occipitoparietal scalp of a 60-year-old man since birth.

BACKGROUND: Both PCNA and Ki-67 have been used as marker for cellular proliferation. The drawback of Ki-67 antibody in immunohistochemistry was that it can be labelled only on fresh tissue, however, MIB1 is a newly developed Ki-67 antiboc which can be labelled on formalin-fixed tissue. OBJECTIVE: The purpase of the present study is to compir the stainability of the Ki-67 antibody with that of the ICNA antibody on formalin-fixed, para fin embedded tissues. METHODS: Using MIE1, the newly developed Ki-67 antibody and PC10(PCNA antibody), speci mens of squamous cell carcinoma(SCC), Bowens disease(BL), actinic keratosis(AK) and basal cell epithelioma(BCE) were stained by one hour immunocytial, mistry using a Microprobe immuno/DNA stainer. RESULTS: The labelling indices (LI) of MIB1 were 82.6%, 37.4%, 38.3% & 81.1% respectively in SCC, BD, AK & BC, while the LI of PC10 were 77.69%, 26.6% & 64.4%. The labelled cells of both antibodies differed in distribution patterns on turmor tissues. CONCLUSION: MIBI cain be used to be an alternative m.rl r for proliferating cells. MIBI PC10, when used together, will be mutually compensatory the study of proliferating cell kinetics.

PURPOSE: Gap junction intercellular communication(GJIC) is an important mechanism of the bystander effect in herpes simplex thymidine kinase/ganciclovir(HSVtk/GCV) gene therapy Therefore, we attempted to enhance the bystander effect in vitro by exogenous overexpressing connexin 37(Cx37) in cells to increase GJIC. METHODS: NIH3T3 cells were transfected with the Cx37 and HSVtk gene or the HSVtk gene alone by the calcium phosphate method, and we detected their expression from these cells by RT-PCR. GCV-mediated cytotoxicity and the bystander effect of each transfectant was then assessed and compared. RESULTS: Cells transfected with HSVtk became sensitive to low concentration of GCV. We found significantly increased cytotoxicity in HSVtk/GCV gene therapy after introduction of the HSVtk and Cx37 genes together compared with the cytotoxicity seen after introduction of the HSVtk gene in vitro. Co-expression of the HSVtk and Cx37 genes potentiates HSVtk/GCV gene therapy through the bystander effect. CONCLUSION: These results indicated that the increase of GJIC using Cx37 have potentiated the by stander effect of HSVtk/GCV therapy, and may be a new approach to improve response in suicidal cancer gene therapy.
