Follicular hamartoma is a rare, benign adnexal tumor with varieties of clinical diversity. But, Histological feature is characterized by a proliferation of immature hair follicle in the dermis with multifocal islands and thickened perifollicular sheath. Pili multigemini is also a rare, developmental anomaly of hair growth with multiple hairs from two or more matrices and papillae in a single pilosebaceous unit. Its prevalence and pathogenesis are unknown. We describe herein a rare case of localized follicular hamartoma with pili multigemini suggesting the possibility of association on pathogenesis between them.

The wood-rotting fungi of three Korean islands in the Yellow Sea, Soyeonpyung-do (SY), Oeyeon-do (OY), and Gageo-do (GG), were investigated from October 2004 to November 2005. During four sampling trips on each island, a total of 46, 44, and 44 specimens were collected from SY, OY, and GG, respectively. The identified wood-rotting fungi from SY included 29 species of 22 genera and nine families; OY had 31 species of 26 genera and 10 families; and GG had 34 species of 27 genera and 11 families. The majority of the fungi were in the Polyporaceae, which was represented by 23 genera and 30 species. Auricularia polytricha, Daedaleopsis tricolor, Daldinia concentrica, Hymenochaete cinnamomea, Hymenochaete yasudai, Hyphoderma setigerum, Lopharia mirabilis, Schizopora paradoxa, and Trametes versicolor were collected from all three islands.

In forensic science practice, age is an important individual information, and one of the indicators to be considered first to depict features of the suspect. Recently, DNA methylation has become a research hotspot in age estimation because of its hig accuracy and stability. New progress has been made in specificity of DNA methylation sites, age estimation in multiple tissues, DNA methylation age estimation of minors, sensitivity of age estimation, forensic practical applications, etc. At the same time, several studies also established more accurate statistical modeling methods, eliminated differences between different detection platforms, found appropriate number of sites in models and analyzed the influence of environment and diseases. This review summarizes these to provide references.

PURPOSE: We report our experience with a case of a nodular lesion of the lower palpebral conjunctiva with histologic features consistent with mucoepidermoid carcinoma. METHODS: A 72 year-old man presented with a left lower palpebral conjunctiva lesion. 3 x 3 mm sized flat pedunculated yellowish red mass was observed. Incisional biopsy proved the mass a mucoepidermoid carcinoma and wide local resection was conducted. RESULTS: Hematoxylin and eosin-stained sections showed lobules of tumor cells, consisting of predominantly epidermoid cells and scattered islands of mucin-secreting cells. Mucicarmine-stained sections demonstrated strong positivity, consistent with the diagnosis of mucoepidermoid carcinoma. CONCLUSIONS: In any case presenting palpebral conjunctival lesion, mucoepidermoid carcinoma should be differentiated, and it is necessary to confirm the diagnosis through biopsy.

Trichoadenoma is a rare, benign, cutaneous tumor with differentiation towards the infundibular portion of the pilosebaceous canal. Clinically, it occurs as a solitary tumor, and most commonly on the face. Histologically, it is characterized by numerous horn cysts lined with squamous epithelium and solid tumor islands in the dermis. A 25-year-old female patient presented with a solitary 0.7x0.7cm sized, skin-colored, central, depressed papule on the right cheek, which had been present for 7 years. Histopathologic findings showed the characteristic features of trichoadenoma.

We analyzed computed corneal topography(EH-270,visioptics, Inc., USA) after excimer laser photorefractive keratectomy(PRK, Omnimed, Summit Technology, Inc., USA) to determine the prevalence f central islands, the factors having an influence on their occurrence, and the corneal ablation patterns. PRK was performed with single zone on 314 consecutive myopias(-1.0D~-11.25D) on which topographic analysis was done at least 3 months after surgery. Corneal ablation patterns were classified as uniform, keyhole, semicircular, and central island. Age, sex, amount of attempted correction, preoperative corneal thickness, and ablation zone(5.0mm vs 6.0mm) were studied whether they can affect on the prevalence of central islands. Topographic results showed a uniform ablation patterns in 213 eyes(67.7%), a keyhole ablation in 54 eyes(17.3%),a semicircular ablation in 18 eyes(5.7%), and a central islands in 29 eyes(9.3%). There was no association between prevalence of centralisland and age, sex, amount of attempted correction, or preoperative corneal thickness(P>0.05). Only one of 81 eye(1.0%) with smaller ablation diameter(5.0mm) presented central islands showing the highly statistical significance(P<0.005) while 28 of the 233 eyes(12%) with larger ablation diameter(6.0mm) presented central islands. In conclusion, we think that the ablation diameter is a risk factor in the prevalence of central island, and the further studies for the etiology of central island, which are based on the optical zone should be needed.

We analyzed the topographic findings of central islands following excimer photorefractive keratectomies(VISX Twenty/Twenty, Inc, Santa Clara, CA) for myopia to evaluate whether the size of the central island was significantly different betwaen 1 week and 6months postoperatively and whether central island at postoperative 6months affected the decrease of corrected visual acuity from preoperative level. There were statistically significant differences in the indices related to the size of central island(peak, height, area) between 1 week(40 patients, 41 eyes) and 6 months(55 patients, 64 eyes) follow-up groups. In 64 eyes of 6months follow-up group, we could not find any statistically significant effect of the indices related to the size of central island on the decrease of corrected visual acuity, except SAI.
