Seborrheic keratosis is a benign epidermal lesion, that commony develops in the aged. It exhibits a remarkable spectrum of histologic variations. We evaluated one hundred and one cases of seborrheic keratoses according to the histologie typing by Lever and Schaurnburg-Lever. The most common histologic type was the acanthotic type(50.5%), and the next. most common one was hyperkeratotic type(33.7%). The rest of the caces were relatively uncommon, irritated type(6.9%), mixed type(4.9%), clonal type(3.9%), adenoidal type(2.0%), and melanoacanthoma(1.0%). In 2 cases, mixed type was found in a lesion.

Background:
Seborrheic keratosis is a benign skin tumor removed through electrodessication, cryotherapy, or surgery. Alternative options may be beneficial to patients with contraindications to standard treatment, or those who prefer a non-invasive approach.
Objectives:
To determine the effectiveness and safety of topical medications on seborrheic keratosis in the clearance of lesions, compared to placebo or standard therapy.
Methods:
Studies involving seborrheic keratosis treated with any topical medication, compared to cryotherapy, electrodessication or placebo were obtained from MEDLINE, HERDIN, and Cochrane electronic databases from 1990 to June 2018.
Results:
The search strategy yielded sixty articles. Nine publications (two randomized controlled trials, two non-randomized controlled trials, three cohort studies, two case reports) covering twelve medications (hydrogen peroxide, tacalcitol, calcipotriol, maxacalcitol, ammonium lactate, tazarotene, imiquimod, trichloroacetic acid, urea, nitric-zinc oxide, potassium dobesilate, 5-fluorouracil) were identified. The analysis showed that hydrogen peroxide 40% presented the highest level of evidence and was significantly more effective in the clearance of lesions compared to placebo.
Conclusion
Most of the treatments reviewed resulted in good to excellent lesion clearance, with a few well-tolerated minor adverse events. Topical therapy is a viable option; however, the level of evidence is low. Standard invasive therapy remains to be the more acceptable modality.

BACKGROUND: Inverted follicular keratosis has distinctive histopathological features and is infrequently encountered by dermatologists. To date, the pathogenesis of inverted follicular keratosis has not been elucidated. Many authors have suggested several theories for the nature of inverted follicular keratosis including verruca vulgaris with squamous eddies, irritated seborrheic keratosis and distinctive follicular tumors. There are no comprehensive studies about the clinical and histopathological features of inverted follicular keratosis in Korea. OBJECTIVE: The purpose of this study was to analyze the clinical features and histopathological findings of inverted follicular keratosis with literature review. METHODS: We studied 14 patients with inverted follicular keratosis for clinical features including the duration of the disease, the location and size of the lesions, the clinical impressions at the first visit and we made a record of the patients' age and sex, histopathological findings. RESULTS: Eight of the 14 patients were male and the ages ranged from 40 to 83 years(mean 59.3 years). The lesions were situated on the face(5/14), scalp(3/14), abdomen(2/14), hand(2/14), buttocks(1/14), shin(1/14). The average size of the lesions was 1.38cm. Seborrheic keratosis was the most common clinical diagnosis(6/14), followed by verruca vulgaris(4/14), cutaneous horn(1/14), melanoma(1/14), soft fibroma(1/14) and pigmented nevus(l/14). Solid and nodular types were the most common histopathological type(7/14), followed by keratoacanthoma-like type(5/14), filiform or wart like type(2/14). CONCLUSION: Inverted follicular keratosis have unusual clinical and histopathological features. We recommend that verrucous plaque lesions should be diagnosed correctly by histopathologic examination and it may be helpful to avoid inappropriate therapeutic approach.
