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.

Neutrophilic dermatosis of the dorsal hands (NDDH) is a recently described skin disorder regarded as a localized variant of acute febrile neutrophilic dermatosis (Sweet syndrome). The lesions of NDDH are characterized by erythematous plaques, pustules, and hemorrhagic bullae on the dorsal surface of the hands. Herein, we report a case of NDDH in a 52-year-old man with concomitant involvement of the ankle. The patient presented with well-demarcated erythematous papules, patches, and plaques on the dorsum of the hands as well as erythematous papules on the left ankle for 3 days. The lesions responded rapidly to systemic corticosteroid therapy.

BACKGROUND: Onychomycosis is one of the most common diseases of the nails accounting for up to 50% of all nail problems. There are many literatures on the cure rate and duration for complete cure according to the various factors. However, little information is available regarding duration required for negative conversion of KOH mount. OBJECTIVE: The purpose of this study was to evaluate the duration required for negative conversion of KOH mount in patients with toenail onychomycosis according to the clinical factors and treatment regimens. METHODS: Medical records of 325 patients with onychomycosis between May 2001 and February 2012 were reviewed retrospectively to obtain the following information: age, sex, presence of diabetes mellitus (DM), extent of nail involvement, therapeutic methods, and result of KOH mount at each timepoint. RESULTS: Extent of nail involvement, old age (> or =60) and DM were negatively associated with the duration required for conversion of KOH mount. Extent of nail involvement also negatively affected the rate of conversion of KOH mount at week 48. Positive KOH mount at week 28 was negatively associated with complete cure. CONCLUSIONS: Extent of nail involvement, old age, and DM can prolong the duration required for negative conversion of KOH mount. Also, positive KOH mount at week 28 had negative effect on the cure of onychomycosis.

Lichen planus is a chronic papulosquamous disease that affects the skin and mucous membranes. It is characterized by pruritic violaceous papules that are most commonly seen on the extremities of middle aged adults, but the elderly are rarely affected. Hypertrophic lichen planus usually occurs on the extremities and especially on the shins, and it tends to be the most pruritic variant. An 82-year-old female presented with severe pruritic multiple papules and plaques on the both the upper and lower extremities for 1 year. At first, the lesions began as small, polygonal papules that formed verrucous plaques over several months. Histopathologic examination showed marked hyperkeratosis, irregular acanthosis and wedge-shaped hypergranulosis. The vacuolar alteration and the lymphocytic inflammatory infiltrate were accentuated at the base of the rete ridge. From these findings, we diagnosed these lesions as hypertrophic lichen planus. The lesions were treated with topical steroid and intralesional injection of steroid, and they were slightly improved after 2 months of therapy.

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.
