Methods Minimum or lowest -apparent diffusion coefficient- (ADC(1)) and representative ADC values (ADC(2)) of 112 renal masses (n: 46 benign renal mass,n: 66 malignant renal mass) were measured on DW-MRI images (b50, 400, 800 s/mm(2)). Signal intensity (SI) measurements were performed in normal renal parenchyma and most avid enhanced area of the renal masses at precontrast, corticomedullary, and nephrographic phases on CE-MRI. Contrast enhancement rate (CER) and contrast enhancement index (CEI) values of renal masses were compared between benign-malignant renal masses and RCC subtypes, oncocytomas, and LP-AMLs. Results There was no significant difference between ADC(1), ADC(2)values, and SI of benign and malignant renal masses (p = 0.721,p = 0.255,p = 0.872). Mean ADC(1)and ADC(2)values of clear cell RCCs were significantly higher than nonclear cell RCCs (p = 0.005p = 0.002). Mean CER value of clear cell RCCs was significantly higher than nonclear cell RCCs in nephrographic phase (p = 0.003). Mean CEI values of clear cell RCCs were significantly higher than nonclear cell RCCs in the corticomedullary and nephrographic phase (p = 0.027 vs. 0.008). LP-AMLs were differentiated from other renal masses with wash-out phenomenon. Conclusion Combined usage of ADC, SI, CER, and CEI values may be useful for discrimination between RCC subtypes, oncocytomas, and lipid-poor AMLs.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 Oral liken planus ve skuamöz hücreli karsinom olgularında Langerhans hücre yoğunluğunun değerlendirilmesi(2020-10-01T00:00:00Z) YILDIZ, PELİN; SÖNMEZ, FATMA CAVİDE; TOSUNER, ZEYNEP; AYTUĞAR, EMRE; YILDIZ, PELİNPublication Metadata only Traumatic Avulsion of Upper Eyelid Skin Following Surgery in a Patient With Multiple Myeloma and Amyloid Light-chain Amyloidosis(2020-09-01T00:00:00Z) ERGÜN, SELMA; ZENGİN, SENİYYE ÜLGEN; ÜNAL, Mustafa; YILDIZ, PELİN; ERGÜN, SELMA; ÜNAL, MUSTAFA; YILDIZ, PELİNMultiple myeloma (MM) is a common hematologic malignancy. Primary systemic amyloidosis or amyloid light-chain (AL) amyloidosis is a rare disease. PURPOSE: This article presents the case of a patient with MM and AL amyloidosis who experienced a severe case of medical adhesive-related skin injury. CASE STUDY: A 64-year-old man with MM, AL amyloidosis, and diabetes presented with a necrotic wound on his left heel that required surgical debridement. The patient experienced a traumatic avulsion of the right upper eyelid skin during the removal of the corneal abrasion preventive tape as well as traumatic avulsion of the left upper eyelid skin while the patient-s face was being cleansed. The avulsed right upper eyelid skin above the tarsus was repaired with a full-thickness skin graft. The partly avulsed left upper eyelid skin was repositioned, and an excisional biopsy was taken. Both upper eyelids healed uneventfully. The biopsy specimen revealed increased amyloid deposition in the dermis, subcutaneous tissue, and areas surrounding the veins and sweat glands. CONCLUSION: This case illustrates the increased risk of medical adhesive-related skin injury and other skin damage in patients with MM and AL amyloidosis. In these patients, the use of tape should be avoided to prevent intraoperative corneal abrasion.Publication Metadata only Proliferating Pilar Tumors: Could Immunohistochemistry be Helpful to Differ Benign and Malignant Forms?(2020-03-01T00:00:00Z) YILDIZ, PELİN; AYDIN ÜLGEN, Övgü; Yol, Cansu; DEMİRKESEN, Cüyan; YILDIZ, PELİNPublication Metadata only Surgical treatment of adult-onset xanthogranuloma(2020-05-29T04:00:00Z) Sonmez Ergun, Selma; KİRAZOĞLU, AHMET; YILDIZ, PELİN; ERGÜN, SELMA; KİRAZOĞLU, AHMET; YILDIZ, PELİN
