A case report of a 6p-year-old man with crokeratosis verruciformis on the dorsa of hands & forearms is presented. This case is unusual in that the patient had late onset of the lesions and lack of a family history of the condition. Literatures are reviewed and possible linkage with Darier's disease is discussed.

Diffuse neonatal hemangiomatosis (DNH) is a rare entity with the distinctive features of multiple hemangiomas of the skin and internal organs, which may result in a fatal outcome if wide-spread involvement of the internal organs. We report a case of DNH with cutaneous and hepatic involvement. The significant regression in the vascular lesions was achieved with systemic corticosteroid therapy.

Tubular apocrine adenoma(TAA) is a rare benign neoplasm usually found on the scalp. It has been designated as an apocrine histogenesis on the basis of its ultrastructural characteristics, enzyme, and immunohistochemical phenotype. Histopathologically the neoplasm consists of tubules or cysts, which show signs of apocrine secretion and sometimes needs to be differentiated from papillary eccrine adenoma. We report a typical case of TAA on nostril which shows differentiation toward apocrine in nature.

Subcutaneous panniculitic T-cell lymphoma(SPTCL) is a rare subtype of peripheral T-cell lymphoma that clinically and histologically mimics benign panniculitis. SPTCL is characterized by subcutaneous nodules on the extremities and trunk. It has a tendency to occur mainly in female adults with eosinophilia, pruritus or hemophagocytic syndromes. Histopathologically, typical lesions of SPTCL show moderate to dense lymphocytic infiltrates in the subcutaneous fat, primarily involving the lobules. Early lesions may show only focal lymphocytic atypia: later lesions display karyorrhexis, necrosis and cytophagia. A 34-year-old woman presented with multiple, recurrent, tender subcutaneous nodules on the abdomen and extremities which she had had for 13 years. There was no hepatosplenomegaly or lymphadenopathy. Skin biopsy specimens revealed atypical small and large lymphocytic infiltrations in the subcutaneous tissue. Occasionally, histiocytes contained erythrocytes and lymphocytes in their cytoplasm. Immunohistochemical staining showed positive reactions to CD45RO and CD43. Negative reactions were seen to CD20, Leu-7 and lysozyme antigen. On the basis of the clinical & histological findings, we established the diagnosis of SPTCL.

Angiocentric T-cell lymphomas have been described as a distinctive clinicopathologic entity in the spectrum of peripheral T-cell lymphomas, with a prominent invasion of blood vessels by lymphomatous cells. In these conditions, the presence of Epstein-Barr virus (EBV) genomes has been demonstrated, suggesting that EBV might play a major role in their cause. Herein, we report a case of cutaneous angiocentric T cell lymphoma associated with the EBV. The patient was diagnosed with nasal angiocentric T cell lymphoma 5 months ago, and treated with cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) combination chemotherapy. After three cycles of CHOP, skin lesions developed. A skin biopsy specimen showed an angiocentric and angioinvasive infiltrate containing some atypical lymphocytes. EBV encoded RNA (EBER) was demonstrated in lesional skin by in situ hybridization.

We report five cases of solitary mastocytoma. All patients were under one year of age and diagnosed as solitary mastocytoma based on clinicopathologic findings. Skin lesions were found on the right forearm, left hand, left leg, left elbow and left shoulder. They resolved themselves spontaneously resolution within 2 or 3 years.

Although many regimens for the acne therapy were proposed and vere used upto date, there is, no ideal choice of treatment. Since a certain relationship between the vitamin A and some dermatoses accompanied, with dyskeratoses had been proposed by Harris in 1932. many studies have been reported for the acne treatment with vitamin A topical or oral administration. (Straumfjord 1943, Lynch & Cook 1947, Anderson & Stokoe 1968). In 1969, Kligman observed the peeling effect of vitamin A acid (VAA), a metabolite of vitamin A, on the human skin and he experienced very good effect of VAA topical application on acne patients. Tbereafter, many authors studied about the VAA and reported the excellent effect on acne (McGills et al. 197l, Mills R Plewig 1972, Juhlin 1975). Moxeover, in 1976, Kim & Lee observed similar results with the authors mentioned above in its cure rate and side effects. In contrast to their high cure rate in those studies, however, its untoward side effects were freqvently elicited with severe intensity. So, author studied the effectiveness and side effects of VAAD which was changed in its chemical structure to diminish the side effects of VAA. Thirty-seven patients (M:F=4:33) were studied, and the results obtained were as follows. 1. The total number of lesions decreased significantly from third week and decreased by half in 4th. week. 2. The number of closed comedones decreased significantly from second week but the number of open comedones temporarily increased in 1st. week and decreased thereafter. 3. pustules and papul s continually decreased but new pustule formation developed in 3 patients and also disappeared in 4 weeks of treatment. 4. Allergic contact dermatitis was developed in 1 patient among 37 patients in 4th. week. 5. There were some undesirable side effects of scaling, pruritus, buming sensation in about 80% respectively, but its intensity was mild or moderate, and fissure, edema and exudation which appeared in VAA treatment were not observed. only a few patients complained tightness, erythema and pain. In comparison with VAA, the duration of treatment with VAAD was delayed about 1-2 weeks and the effectiveness in acne therapy with VAAD was almost equal to VAA therapy, and the side effects were markedly diminished.

Our present knowledge of impetigo contagiosa extends from its first description as a separate clinical entity by Fox in I864, and the proof of its bacterial etiology by Radcliffe-Crocker in 1881. Both staphylococci and streptococci have been discovered from the lesions, but the relative preponderance of each varies greatly, and reports are contradictory. Seventy-eight patients with impetigo contagiosa were studied bacteriologically in order to ascertain the primary etiologic agent. Also, a susceptibility test (Bauer- Kirby method) was done on the isolated organisms with 7 antibiotics which are used frequently in the clinical field. Specimens obtained from the skin lesions were cultured and organisms were isolated. They were identified by various biochemical and serological tests. A DN ase test, a carbohydrate fermentation test, and a coagulase test were done for the isolated staphylococci. A bacitracin disc method and a precipitin test(Lancefield method) were done for the isolated B-hemolytic streptococci. The results were as follows: Fifty-six cases(71.8%) were infected by staphylococcus only. Twenty cases(25.6%) were infected by a mixture of staphylococcus and p-hemo- lytic streptococcus. Only 2 cases(2.6%) were infected by B-hemolytic streptococcus alone. All 76 strains of staphylococci were identified as coagulase positive staphylococci. Among the 22 strains of B-hemolytic streptococci, 15 strains were identified as group A and remaining 7 strains were identified as group B. Coagulnse negative sta,phylococcus was not found. In the susceptibility test to 7 antibiotics, staphylococci showed susceptibility to lincomycin, erythromycin, cloxacillin, and chloramphenicol, and resistance to tetra-cycline, penicillin, and ampicillin. Streptococci showed susc.ptibility to all of the above antibiotics except tetracycline. From the results of this experiment, it was concluded that the primary etiologic agent of impetigo contagiosa was coagulase positive staphylococcus and streptococcus for the most part can be considered as a secondarily infecting agent. Coagulase negative staphylococcus apparently is not implicated as an etiologic agent of impetigo contagiosa. The results of the antibiotic susceptibility tests would seem to indicate that the use of such antibiotics as tetracycline, penicillin, and ampicillin is not indicated in the treatment of impetigo contagiosa.
