The aetiology of pigmented purpuric dermatosis is unknown. Dermatoscopy is a non-invasive diagnostic technique that allows the visualisation of morphological features invisible to the naked eye; it combines a method that renders the corneal layer of the skin translucent with an optical system that magnifies the image projected onto the retina. Objectives:: The aim of this study is to investigate the dermatoscopic findings of pigmented purpuric dermatosis. Methods:: This study enrolled patients diagnosed histopathologically with pigmented purpuric dermatosis who had dermatoscopic records. We reviewed the dermatoscopic images of PPD patients who attended the outpatient clinic in the Istanbul Dermatovenereology Department at the Bezmialem Vakıf University Medical Faculty. Results:: Dermatoscopy showed: coppery-red pigmentation (97%, n = 31) in the background, a brown network (34%, n = 11), linear vessels (22%, n = 7), round to oval red dots, globules, and patches (69%, n = 22; 75%, n = 24; 34%, n = 11; respectively), brown globules (26%, n = 8) and dots (53%, n = 17), linear brown lines (22%, n = 7), and follicular openings (13%, n = 4). Conclusion:: To our knowledge, this is the first study to report the dermatoscopy of pigmented purpuric dermatosis. In our opinion, dermatoscopy can be useful in the diagnosis of pigmented purpuric dermatosis.Publication Metadata only Evolution of Spitz Nevi(2017-07-01) Su, Ozlem; Emiroglu, NAZAN; Yildiz, PELİN; OZKAYA, Dilek Biyik; Bahali, ANIL GÜLSEL; Onsun, NAHİDE; EMİROĞLU, NAZAN; YILDIZ, PELİN; BIYIK ÖZKAYA, DİLEK; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEBackground/ObjectivesSpitz nevi are melanocytic lesions with clinical, dermoscopic, and histopathologic presentations that may resemble those of melanoma. The evolution of Spitz nevi is a well-known feature. The objectives of this study were to investigate the clinical and dermoscopic features of Spitz nevi and define their evolution.Publication Metadata only Challenges in early diagnosis of primary cutaneous CD8+ aggressive epidermotropic cytotoxic T-cell lymphoma: a case series of four patients.(2020-08-01T00:00:00Z) Akaslan, TÇ; Dizman, D; Emiroğlu, N; Tosuner, Z; Çetin, G; Demirkesen, C; ONSUN, NAHIDE; YILDIZ, PELİN; ÇETİN, GÜVENBackground: Primary cutaneous aggressive epidermotropic CD8+ cytotoxic T-cell lymphoma (AECTCL) is a rare and aggressive lymphoma characterised by ulcerated lesions and a poor prognosis. Objectives: To present a case series of four previously misdiagnosed AECTCL patients and discuss the importance of early diagnosis. Materials and methods: All patients in this study were identified from the database of the Dermatology Department of the Medical School of Bezmialem Vakif University, based on clinical and histopathological diagnosis of AECTCL between 2010 and 2018. Results: AECTCL cases may mimic many benign dermatoses and accurate diagnosis may be delayed. Conclusion: Because of its poor prognosis, early diagnosis of AECTCL may be helpful in improving the likelihood of patient survival, but further study is needed to address the challenges in diagnosing this rare and aggressive lymphoma.Publication Metadata only Extramammary paget disease: Case report Ekstramammaryan Paget Hastaliǧi(2016-12-30) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; SU, Özlem; Tosuner, ZEYNEP; BAHALI, ANIL GÜLSEL; YILDIZ, PELİN; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BIYIK ÖZKAYA, DİLEK; TOSUNER, ZEYNEP; SU KÜÇÜK, ÖZLEM; BAHALI, ANIL GÜLSEL; YILDIZ, PELİN; ONSUN, NAHIDEPublication Metadata only Correlation of Clinical, Dermoscopical and histopathological features of all subtypes of basal cell carcinoma(2017-05-06T00:00:00Z) DİZMAN, DİDEM; BIYIK ÖZKAYA, DİLEK; BAHALI, ANIL GÜLSEL; TOPUKÇU, BUĞÇE; YILDIZ, PELİN; TOSUNER, ZEYNEP; DEMİRKESEN, CÜYAN; ONSUN, NAHİDE; SU KÜÇÜK, ÖZLEM SU; BAHALI, ANIL GÜLSEL; YILDIZ, PELİN; ONSUN, NAHIDE; SU KÜÇÜK, ÖZLEMPublication Open Access Clinical and histopathological improvement of scleromyxedema-induced microstomia after hyaluronidase injection(2022-05-01T00:00:00Z) AKASLAN, TAHSİN ÇAĞDAŞ; YILDIZ, PELİN; ONSUN, Nahide; AKASLAN, TAHSİN ÇAĞDAŞ; YILDIZ, PELİN; ONSUN, NAHIDEIntroduction Scleromyxedema is a rare primary cutaneous mucinosis characterized by numerous firm, waxy, confluent papules. Recently, intravenous immunoglobulin (IVIG) is accepted by many authors as the first-line treatment option for severe cases. We report a 69-year-old male patient who has been suffering from scleromyxedema, with reduced mouth opening. He has been on a high-dose IVIG regime for 5 years. Methods The patient stated that he had difficulty in wearing and removing his dentures because of reduced mouth opening lately. Before considering to add any other immunosuppressants to his regime, we injected 1500 IU of hyaluronidase in total in one session periorally. The patient has been told open his mouth maximum and photographs have been taken before injections and after one month. We used a photo measurement application when evaluating microstomia to increase accuracy. We also took punch biopsies in order to evaluate effect of hyaluronidase histopathologically before and one month after injections. Results One month later, he was able to reattach and remove his dentures without adding any adjuvant immunosuppressants other than hyaluronidase. Mouth opening was increased in measurements and histopathologically, mucin deposition, fibroblastic proliferation, and perivascular lymphocytic infiltration were decreased. Conclusions We think hyaluronidase is a safe, easily accessible, and effective treatment option for microstomia caused by scleromyxedema.Publication Metadata only Evolution of Spitz Nevi.
