    Poxvirus-induced angiogenesis after a thermal burn
    (2014-09-01) Biyik Ozkaya, DİLEK; TASKIN, Banu; TAS, Betul; ASIRAN SERDAR, Zehra; Demirkesen, Cuyan; Su, Ozlem; Onsun, NAHİDE; BIYIK ÖZKAYA, DİLEK; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDE
    Orf (contagious ecthyma) is a zoonotic infection caused by a dermatotropic parapoxvirus that commonly infects sheep, goats, and oxen. Parapoxviruses are transmitted to humans through contact with an infected animal or fomites. Orf virus infections can induce ulceration, and papulonodular, pustular, or ecthymic lesions of the skin after contact with an infected animal or contaminated fomite. Rarely, orf virus provokes extensive vasculo-endothelial proliferation as a skin manifestation. Here, we present the case of an 8-year old female with poxvirus-induced vascular angiogenesis that developed 10days after a thermal burn. An 8-year-old female presented at our outpatient clinic with red swellings and a yellow-brown crust on them. After a thermal burn with hot water, she went to a clinic and the burn was dressed with nitrofurazone and covered for 2days. When the dressing was removed after 2days, nodules were seen in the burnt areas. When the clinical findings were considered with the histopathological features, a reactive vascular proliferation due to a viral agent was suspected. Following PCR, parapoxvirus ovis was detected. Viral infections such as pox virus can trigger pyogenic granulomas or pyogenic granuloma-like vascular angiogenesis. Infectious agents must be considered when dealing with pyogenic granuloma-like lesions.

    Demographic characteristics, aetiology, and assessment of treatment options in leukocytoclastic vasculitis.

    Introduction: Vasculitides are a heterogeneous group of diseases characterized by inflammation of the blood vessel walls. Etiological factors include infections, drugs, connective tissue diseases, and malignancies. Aim: To examine the demographic characteristics, etiological factors, and treatment options in 75 patients with leukocytoclastic vasculitis. Material and methods: The study included 75 patients diagnosed with leukocytoclastic vasculitis at our clinic. The patients’ medical records were reviewed to determine their age, sex, presence of systemic symptoms, possible etiological factors, laboratory results, types of cutaneous lesions, locations of the lesions, treatment options, and disease course. Results: There were 43 women and 32 men. Cutaneous lesions affected only the lower limbs in 60 of the 75 patients (80%) and usually presented as palpable purpura (64%, n = 48). Arthralgia (26.7%, n = 20) was the most frequent extracutaneous symptom. Of the patients with secondary vasculitis, the most common causes were infections and drugs. The mean age of the patients with Henoch-Schönlein purpura was 26.8 years. There was no significant association between age and renal, gastrointestinal, or joint involvement. Conclusions: The most common form of vasculitis in our study was cutaneous leukocytoclastic vasculitis. In most of the patients it appeared to be idiopathic. Among drugs, antibiotics were the most common etiological factor. In 4 patients, the cutaneous leukocytoclastic vasculitis behaved like the paraneoplastic syndrome.

    Evolution of Spitz Nevi

    Background/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.

    Non-healing ulcer on the foot: early onset unilateral Mali-type acroangiodermatitis.
    (2013-01-01) OZKAYA, DB; Su, O; ONSUN, NAHİDE; ULUSAL, H; DEMIRKESEN, C; BIYIK ÖZKAYA, DİLEK; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDE
    Acroangiodermatitis (pseudo-Kaposi's sarcoma, AAD) is a benign vascular dermatosis that resembles Kaposi's sarcoma clinically and histopathologically (1). Four types have been defined: the Stewart-Bluefarb type accompanying chronic arteriovenous malformations, the Mali type accompanying stasis dermatitis, a type accompanying the first gestation, and a type accompanying arteriovenous shunts in patients with chronic kidney failure (3). Although AAD development is associated with chronic venous failure, less frequently AAD can develop as a complication of extremity paralysis, hemodialysis, post-traumatic arteriovenous fistula, amputated extremities, and vascular malformations (e.g., Klippel-Trénaunay syndrome). Pseudo-Kaposi's sarcoma can be histopathologically and clinically confused with malignant diseases such as Kaposi's sarcoma (1, 4). A 22-year-old male was referred to our outpatient clinic with a complaint of a non-healing wound on the distal phalanx of the left first toe. The patient was referred to various centers for 2 years and stated that he had received infection treatments but that his complaints did not disappear. An AAD diagnosis was established for the patient based on clinical and histopathologic evidence. Because he had early-onset disease and it was unilateral, the diagnosis was delayed. In addition, due to the rare occurrence of the disease, we histopathologically diagnosed this patient as having acroangiodermatitis.

    Evaluation of Mean Platelet Volume in Patients with Pigmented Purpuric Dermatosis
    (2017-01-01) Su, Ozlem; Bahali, ANIL GÜLSEL; OZKAYA, Dilek Biyik; Cengiz, FATMA PELİN; Emiroglu, NAZAN; Kaya, MEHMET ONUR; Onsun, NAHİDE; BAHALI, ANIL GÜLSEL; BIYIK ÖZKAYA, DİLEK; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; KAYA, MEHMET ONUR; ONSUN, NAHIDE
    Objective: Pigmented purpuric dermatosis (PPD) is a chronic skin disease characterized by petechial and pigmentary macules. The etiology of the disease remains unknown. Mean platelet volume (MPV) is a marker of platelet (PLT) function and activation. PLTs play important roles in inflammation and innate and adaptive immunity in addition to their roles in hemostasis and thrombosis. In this study, we investigated the possible association between MPV and PPD.
