Publication Open Access Dermatoscopic findings of pigmented purpuric dermatosis(2016-09-01) Su, Ozlem; OZKAYA, Dilek Biyik; Emiroglu, NAZAN; Cengiz, FATMA PELİN; Bahali, ANIL GÜLSEL; Yildiz, PELİN; DEMIRKESEN, Cuyan; Onsun, NAHİDE; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; CENGİZ, FATMA PELIN; BAHALI, ANIL GÜLSEL; YILDIZ, PELİN; ONSUN, NAHIDEackground:: Pigmented purpuric dermatosis is a chronic skin disorder of unknown aetiology characterised by symmetrical petechial and pigmented macules, often confined to the lower limbs. 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 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 Open Access Pemphigus vulgaris localised exclusively to the penis(2015-05-01) Su, Ozlem; Dizman, DİDEM; OZKAYA, Dilek Biyik; Yildiz, PELİN; Demirkesen, Cuyan; Onsun, NAHİDE; SU KÜÇÜK, ÖZLEM; DİZMAN, DİDEM; BIYIK ÖZKAYA, DİLEK; YILDIZ, PELİN; ONSUN, NAHIDE
