We report herein two cases of leukemia cutis. One case is a 54-year-old woman who came to our department with complaints of a solitary ulcerating nodule on her left leg that had been present for 2 months since prior to her visit. Through histopathological studies, the diagnosis of myelocytic leukemia cutis was made before the final diagnosis of acute myelocytic leukemia was made by hematological studies. When combined chemotherapy was finished, she was in a partial remission state and the nodule disappeared after 1 month of chemotherapy. The other case is a 77-year-old man having multiple infiltrative nodules on the right forearm and right thigh for 1 month prior his visit. He was diagnosed as having leukemia cutis for his skin lesions histopathologically. This was redefined as chronic myelomonocytic leukemia of the myelodysplastic syndrome with blastic transfor- mation by hematological examination. He developed septicemia and died 3 weeks after the dermato- logical diagnosis.

We herein report a case of nasal type T/natural killer(NK)-cell lymphoma(TNKCL). This lymphoma is characterized by the expression of CD2, CD43 and NCAM(CD56) antigen, an aggressive clinical course, frequent extranodal spreading, a strong association with Epstein-Barr virus(EBV), and the absence of T-cell receptor(TCR) gene rearrangement. NCAM antigen is known to be a possible determinant of extranodal dissemination of peripheral T-cell lymphoma(PTCL). The patient is a 70-year-old male with skin lesion on his forearm. Histopathological and immunohistochemical studies were diagnostic of EBV-associated TNKCL. Untill now, he has failed to respond to anticancer therapy.

We herein present a case of a 2-year-old girl with non-Hodgkin's lymphoma(NHL) of the lymphoblastic type involving cutaneous sites at the time of diagnosis. The histological finding was typical of lymphoblastic lymphoma. However, immunophenotypically, this lymphoma was not of the T-cell or B-cell type, although the vast majority of lymphoblastic lymphomas involving the skin are usually of the pre-B cell or T-ce11 type. Until now, there have been few reports of non-T, non-B primary cutaneous lymphoblastic lymphoma expressing surface CD10 and CD56 antigens as in this case.

We herein report a case of secondary cutaneous diffuse large B-cell lymphoma(DLBCL) occurring in a 66-year-old woman. The skin lesions were erythematous infiltrative nodules on the right inguinal area. Histologically, the skin lesion disclosed DLBCL mainly composed of immunoblasts. Concurrently, she showed lymph node involvement. Initially, however, we could not define the conclusive temporal sequences between nodal lesions and skin lesions. Finally, additional further studies revealed this case as secondary cutaneous 8-cell lymphoma, and she was managed with systemic chemotherapy.

Peripheral T-cel1 lymphoma(PTCL) encompasses histopathologically and clinically various spectra of cutaneous T-cell lymphoma(CTCL). In this report, we describe two cases of PTCL showing diRerent clinical courses according to EBV(Epstein-Barr virus) positivity. The chnical course of case 1 with EBV-associated PTCL was rapidby fatal and refractory to intensive chcmotherapy. However, in case 2, EBV genomes were not found in her lesional tissues and she showed an indolent clinical course withoaat systemic symptoms. Accordingly, serological and immunohistochemical investigations for EBV might be mandatory in cutaneous PTCL to evaluate clinical prognosis.

BACKGROUND: Specified clinical observations regarding skin changes in viral hepatitis have not yet been accomplished in Korea, especially in view of serotypes. OBJECTIVE: This study was conducted to identify various cutaneous manifestations of viral hepatitis according to viral serotypes and the stages of the disease. METHODS: We performed a clinical observation of cutaneous manifestations in 450 patients who were diagnosed with viral hepatitis. RESULTS: 1. Cutaneous manifestations were found in 383(85.1%) patients. Patients with a longer duration seemed to have skin lesions more frequently. 2. The frequency of cutaneous manifestations was highest in HAV(94.4%) and HBV(84.9%) serotypes. The most common cutaneous manifestation was pruritus(32.4%) in all studied subjects. In HBV hepatitic patients, the most common cutaneous manifestation was pruritus(35.4%), in HCV hepatitic patients, vasculitic purpura(74.5%), in HAV hepatitic patients, urticaria(88.8%), in the hepatitic patients with the mixed form, spider angioma(30.2%) and vasculitic purpura(30.2%). 3. Urticarial lesions in non-HCV hepatitis were of the lymphocytic vasculitis type but HCV hepatitis was associated with neutrophilic vasculitis. The purpuric lesions with HCV hepatitis were of the neutrophilic vasculitis type while lymphocytic vasculitis was present in non-HCV hepatitis. 4. The most severe pruritus was present in HBV hepatitic patients. CONCLUSION: The cutaneous manifestations in viral hepatitis have different clinical features depending on the viral types.

This study was performed to investigate clinical and histopathologic features of steroid acne, which was induced by systemic administration and topical application of corticosteroids. Thirty five cases of steroid acne visited to Department of Dermatology, Hangang Sacred Heart Hospital from September, 1g79 to June, 1984 were analyzed, and the results obtained can be summarized as follows: 1. The peak age of the subjects was third decade(42.9%) with an average age of 30. 1 years, and male to female ratio was l.9: 1,2. The skin lesions had unique clinical features that showed many, uniform sized, erythematous papules and pust;ules. 3 The predilection sites of steroid acne induced by systemic steroid therapy were anterior chest(93.1%), back(44,8%), neck(31.0%), shoulder(31.0%) and face (20.7%) 4 Among thirty five cases of steroid acne, twenty cases were induced by parenteral adrninistration of dexamethasone disodium phosphate(group A), nine cases by oral administration of prednisolone(group B), and six cases by topical application of three kinds of steroid creams(group C). 5. The mean induction time after starting steroid in group A(ll. 3 days) was shorter than those in group B and C(18.9 days and l4.8 days respective)y). The mean total dosage of used steroid in group A was 191. 3mg of dexamethasone disodium phosphate and that in group B was 515. 7mg of prednisolone. On histopathologic findings of twenty two skin biopsy specimens of the three groups, perivascular inflammatory reaction was the most common finding followed by intra-and peri-follicular inflammatory reaction, dermal vascular dilatation, necrosis of follicular epithelium, comedo, intraand periollicular abscess and rupture of follicle.

We herein report a case of Richters syndrome(RS) that was discovered following an investigation of a skin lesion. RS represents an acute transformation of chronic lymphocytic leukemia(CLL) to highly malignant large cell lymphoma such as diffuse large B-cell lymphoma(DLBCL). RS is characterixed by abrupt B-symptoms, rapidly progressive lymphadenopathy, hepatosplenomegaly, frequent extranodal involvement, hypercalcemia and an unfavorable clinical course. The patient is a 31-year-old male with skin lesions on his face. He had been previously diagnosed with CLL. At his presentation, CLL and DLBCL manifestly co-existed. Our multistage analysis suggested that DLBCL and CLL might arise from a different B-cell clone. He showed a poor clinical response to systemic chemotherapy.

Herein we report two cases of leukemia cutis that were responsive to oral all-tratm retinoic acid(ATRA) therapy. The two presented patients, who had been diagnosed with acute pmmyelocytic leukemia, disclosed specific lesions of leukemia cutis through histopathological examinations. Leukemia cutis due to acute promyelocytic leukemia is characterized by PML/RAR-a chimeric fusion proteins which arise from chromosomal trmslocation. This PML/RAR-a transcript can be a valuable molecular therapeutic target to systemic retinoid therapy in that ATRA induces terminal differentiation of leukemic clones and PML/RAR-a transcript preserves the ATRA-responsive signal transduction pathway. We concluded that leukemia cutis might be treated by tretinoin therapy without notifi.able adverse effects.
