"Latar belakang : nevus melanositik didapat (NM) adalah salah satu kelainan pigmentasi melanositik yang dapat menjadi prekursor potensial melanoma. Telah diketahui bahwa tipe kulit putih merupakan salah satu faktor risiko terjadinya melanoma. Pola dermoskopi NM pada populasi kulit putih memiliki gambaran dermoskopik yang berbeda pada setiap tipe kulit (tipe I ? IV) menurut klasifikasi Fitzpatrick. Belum pernah dilaporkan perbedaan gambaran dermoskopik pada tipe kulit orang Indonesia yang umumnya berkulit sawo matang dengan tipe kulit IV dan V. Dianggap penting untuk mengetahui karakteristik gambaran klinis dan dermoskopik NM pada tipe kulit orang Indonesia yang meliputi tipe kulit III, IV dan V. Metode : penelitian ini menggunakan rancangan potong lintang, pada 96 subyek penelitian (SP) dewasa (usia 18-60 tahun) di Poliklinik IKKK RSCM Jakarta terbagi merata untuk setiap tipe kulit III, IV dan V. Dilakukan pemeriksaan gambaran klinis dan dermoskopik NM pada tiap SP. Gambaran klinis yang dinilai adalah morfologi klinis dan warna lesi. Hasil : didapatkan gambaran klinis NM yang paling banyak adalah lesi datar (88,44%), berwarna cokelat gelap (51,43%), dengan median ukuran 2 mm. Pola dermoskopik yang paling banyak ditemukan pada seluruh lesi NM adalah retikular (33,40%). Terdapat proporsi dan kecenderungan yang semakin meningkat pada pola retikular dengan meningkatnya kegelapan tipe kulit orang Indonesia (tipe kulit IV terhadap tipe kulit III OR 1,4 (95% CI 0,5-4,0); tipe kulit V terhadap tipe kulit III OR 1,7 (95% CI 0,6-4,8)). Kesimpulan : Tidak terdapat perbedaan gambaran klinis NM pada tiap tipe kulit orang Indonesia. Terdapat perbedaan pola dermoskopik pada tipe retikular dengan proporsi yang makin meningkat sesuai dengan tipe kulit yang makin gelap.

Background : Acquired melanocytic nevi (MN) is one of melanocytic pigmentation disorder, which can be a potential precursor of melanoma. Fair skin type has been known as one of the risk factor for melanoma. The dermoscopic pattern of MN in white population is different among the skin types (type I ? IV) according to Fitzpatrick?s classification. The difference in dermoscopic pattern of MN among the skin types of Indonesian people, which commonly dark brown with types IV and V, has not been reported. It is important to know the clinical characteristics and dermoscopic pattern of MN in Indonesian people skin types, which includes the skin types of III, IV and V.

Method : We performed a cross sectional study in 96 adult patients (18-60 years old), distributed equally for each skin type III, IV and V, at the Dermatovenereology outpatient clinic Dr Cipto Mangunkusumo hospital Jakarta. Each subject was examined for clinical and dermoscopic pattern. Clinical characteristic include clinical morfology and color.

Result : The study found that the most frequent clinical characteristics of MN were planar lesion (88.44 %), dark brown color (53.43%), with median size 2 mm. The most frequent dermoscopic pattern in all MN lesions was reticular (33.40 %). There was increasing proportion and odds within reticular pattern with the increase of skin?s darkness of Indonesian people (skin type IV to type III with OR 1.4 (95% CI 0.5-4.0); skin type V to type III with OR 1.7 (95% CI 0.6-4.8), respectively).

Conclusion : Clinical characteristics were not significantly different among the skin types of Indonesian people. There was difference on dermoscopic pattern within the reticular type, showing an increase of its proportion in accordance with the darker skin types."

"The “Abtropfung” theory that nevi develop through the migration of nevus cells from the epidermis to the dermis prevailed for almost a century until the “Hochsteigerung” theory postulated the reverse pattern of migration. Most recently, however, new insights gained from epidemiology, cross-sectional and longitudinal studies of nevi, dermoscopy and confocal microscopy, and cellular and molecular studies have brought into question both of these theories. This book provides a comprehensive guide to current knowledge about nevogenesis by presenting these latest advances and in addition discusses issues yet to be resolved. It will assist practicing physicians in effectively managing patients with a variety of nevi and will also be of great value to researchers in the field. Importantly, since nevi are associated with an increased risk of melanoma, understanding nevogenesis may help to unravel some of the mysteries of melanomagenesis."

"Nevus of Ota is a dermal melanocytic nevus which is characterized by benign hamartomatous hyperpigmentation.Clinically it presents as a congenital or acquired blue or gray patch on the face and is distributed on the ophthalmic,maxillary, and mandibular branches of the trigeminal nerve. It is most commonly found in Japanese populationsand is rare in the Indian subcontinent. It affects only 0.014 – 0.034% of the Asian population and is less commonin the male population, with a male to female ratio of 1.4:8. The involvement of pigmentation over the pinna of theear and the oral mucosa is extremely rare with very few cases reported in scientific literature. The case reportedhere is a case of nevus of Ota, with a rare intraoral presentation on the hard palate, crossing the midline."

Background: Malignant melanoma (MM) is a malignant tumor originating from

proliferation of melanocyte cells and can be found in skin, mucosa and ocular. The

mortality rate for malignant melanoma is quite high, especially at advanced stage

characterized by metastases. Various risk factors can predispose MM into metastases,

which can be different in cutaneous, mucosal and ocular MM, one of which is the

immunological process of the tumor which can be assessed from Tumor Infiltrating

Lymphocyte (TIL). TIL components that play a role in the process of avoiding the immune

system in malignant melanoma are regulatory T cells, whose the most specific marker so

far is Foxp3. The association of Foxp3 with clinical stage of malignant melanoma is still

controversial and until now there has been no research on the association of Foxp3 in

TIL with clinical stage of MM in Indonesia.

Aims: This study aims to determine the association between clinicopathological

characteristics and Foxp3 expression in TIL with MM clinical stage.

Methods: Analytic study on malignant melanoma diagnosed at Anatomical Pathology

Department FKUI/RSCM during January 2010 until December 2021. Sampling was

carried out by total sampling from cases that met the inclusion criteria according to the

calculation of the sample size for each group. Immunohistochemical examination using

Foxp3 monoclonal primary antibody. Immunoexpression data were analyzed to

determine its relationship with clinical stage of malignant melanoma.

Result: There were 54 cases of MM: 19 cases were skin MM, 29 cases of ocular MM, and

6 cases of mucosal MM. Majority of cases (63%) were in advanced stages. Tumor

thickness and mitosis associated with clinical stage of cutaneous and overall MM. Female

gender, tumor thickness >2 mm, mitoses >16/10 HPF, presence of lymphovascular

invasion and perineural invasion generally had low Foxp3 expression. In cutaneous MM

and overall MM, low Foxp3 expression was found at advanced clinical stage although

no significant association was found.

Conclusion: Tumor thickness and mitosis associated with clinical stage of cutaneous and

overall MM. Clinicopathological characteristic was not statistically significant with

Foxp3 expression. Low Foxp3 expression was associated with advanced clinical stage

although no statistically significant association was found."

Background: Condyloma acuminatum (CA) is the most common sexually transmitted infection. Although, it is stated that low-risk HPV types 6 and 11 are associated with 90% of genital warts, but there is no publication in Indonesia about identification of HPV types in various CA clinical manifestations.

Purpose: To identify HPV type among various clinical pictures of anogenital warts.

Method: A cross-sectional study is conducted in Dermato-Venereology Clinic Dr. Cipto Mangunkusumo National Hospital, Jakarta. Twenty five men and 12 women (20-57year-old) from April to July 2013 were eligible in this study. Fourty DNA samples from 40 lesions of 37 subjects with various clinical pictures of CA were collected. The HPV typing was based on PCR and dot blot hybridization using the HPV express matrix® which detects 21 HPV types of high- and low-risk, able to identify multiple types from a single specimen.

Result: Multiple clinical manifestations were found on 3 of 37 subjects (8%). HPV types were identified among 34lesions (85%). Four clinical manifestations of CA and HPV typing were documented: (1) classic 26 of 40 lesions (65%): low-risk HPV types (6, 11, 43), predominated in 18 samples, while 7 samples were co-infected with the high risk types and another sample had unidentified HPV types. (2) keratotic 2 lesions (5%): 1 sample only harbour the high risk HPV type 52, while the other was unidentified. (3) smooth papule 9 lesions (22.5%): Low-risk HPV types (6, 11, 42, 43) were found in 4 samples, while 3 samples were co-infected with the high risk types, while 2 others were unidentified, and (4) flat top papule to plaque 3 lesion (7.5%): 2 samples were unidentified and the other was high risk HPV type 52. HPV 6 and 11 can be identified in 28 samples (70%). The low risk HPV type had been identified were 6, 11, 42, and 43, while the high risk type were 16, 31, 35, 39, 45, 52, 56, 66, and 68.
