Intracranial meningioma is a common benign tumor. Although tumor mass might have been totally removed, aggravation of symptoms or recurrence of mass may sometimes be noticed. Histopathologic finding has been known as one of probable prognostic factors in meningiomas. In this study, correlation between DNA contents and histopathologic findings were evaluated to elucidate further such factors having role in the recurrence or prognosis in meningiomas. Seventy four cases of meningiomas were selected to review clinical prognosis and histopathologic findings. The speciemens were re-evaluated with flow cytometry to get DNA histogram. DNA fractions and proliferation index(PI) were calculated. The correlations were statistically analyzed with t-test and ANOVA test. Benign meningiomas were 53(71.6%), atypical 19(25.7%), and malignant 2(2.7%). PI of benign was 10.80+/-1.36 and that of atypical being 18.00+/-5.19. Diploid cases were 48 in number(64.9%) and aneuploid 26(35.1%). PI of diploid was 8.10+/-5.56 and that of aneuploid 24.06+/-18.51. DNA index was 1.00+/-0.00 in enign, 1.00+/-0.33 in atypical, and 1.50+/-0.71 in malignant. There was one case(2%) in benign, 2(11%) in atypical, and 2(100%) in malignant meningioma which showed recurrence(p=0.0002). In benign meningioma, 1 out of 4 subtotally removed cases recurred whereas atypical and malignant meningiomas recurred even in totally removed cases. In conclusion, histopathologically malignant meningiomas have not been always aneuploid. If total removal is done in benign tumor, long-term follow-up is not needed because of no recurrence and no aggravation of symptom. Atypical meningioma with aneuploid and high PI(above 24) should be followed in longer duration, and malignant meningioma should be closely observed due to their higher recurrence rate.

BACKGROUND: The presence of serum varicella zoster virus (VZV) immunoglobulin M and G (IgM and IgG) aid diagnosis of and confirmation of immunization against varicella and herpes zoster. However, the relationship between serum VZV IgM and IgG and the clinical characteristics of VZV infection remains unclear. OBJECTIVE: We evaluated quantitative changes in serum VZV IgM and IgG in accordance with the clinical features of varicella, herpes zoster, and disseminated herpes zoster compared with a normal control group. METHODS: A total of 922 patients were classified into 3 groups: varicella, herpes zoster, and disseminated herpes zoster. We assessed serum VZV IgM and IgG titers in association with age, severity of skin lesions, duration of skin lesions, immune status, and neurologic complications. RESULTS: In patients with varicella and herpes zoster, serum antibody titer varied significantly depending on age and the duration of skin lesions. A high serum VZV IgM titer was related to varicella or disseminated herpes zoster viremia. In herpes zoster, elevated antibody titers, especially VZV IgM, were associated with severe skin lesions and the presence of neurologic complications. CONCLUSION: Serologic data for varicella and herpes zoster varied according to clinical features. A high serum VZV IgM titer was associated with an unfavorable clinical course of herpes zoster.

Glomus tumors are benign cutaneous neoplasm, occurring in the vascular hamartomatous tubercles of the glomus body, which is a myoarterial apparatus typically found in the reticular dermis of the skin. Histopathologically, glomus tumors are composed of neoplastic cells that resemble normal glomus cells, arranged around a varying number of thin-walled, sometimes branching capillaries. Immunohistochemically, neoplastic cells in glomus tumors clearly exhibit smooth muscle characteristics with expression of muscle-specific actin and alpha-smooth muscle actin; whereas, the expression of CD34 is rare. In this report, we present two cases of benign glomus tumors on the subungual area and palm. Tumor cells of glomus tumor in two patients were both positive for smooth muscle actin (SMA) and CD34 immunohistochemical staining. We thought that coexpression of SMA and CD34 adds support to the interpretation of these lesions as a family of perivascular neoplasms.

Necrobiosis lipoidica (NL) is a chronic granulomatous skin disease typified by indurated plaques on the shin. Although this condition is strongly associated with diabetes mellitus, its etiology and pathogenesis remains unknown. Localization of NL to the lower extremities suggests that local injury may be a contributing factor to the disease. A healthy 38-year-old man presented with localized erythematous to yellowish plaques on his right thigh that developed over several years. The lesion developed in the scar where suture had been done for laceration repair 25 years ago. A biopsy specimen showed degenerated collagen with surrounding palisading granulomas. Numerous lymphocytes and multinucleated giant cells were infiltrated throughout the reticular dermis. Plasma cells aggregation was found at the dermal subcutaneous junction.

Vestibular papillomatosis is an uncommon benign condition that can occur on labia minora and is considered as a normal anatomical variant of the vulva, as the female equivalent of pearly penile papules in men. Because vestibular papillomatosis resemble condyloma, it can be misdiagnosed as condyloma acuminatum and can lead to unnecessary treatment. We herein report a case of a 27-year-old women with multiple skin-colored soft papules on labia minora. The lesion was distributed symmetrically on the inner of labia minora and showed a separate base of individual projection. To the best of our knowledge, this is a unique case reported in the Korean dermatological literature.
