(2021) Mansur, Ayse Tulin; Karsiyakali, Nejdet; Demirci, Gulsen Tukenmez; Koseoglu, Hikmet; Akman, Yavuz; Yildiz, Semsi; 0000-0002-0416-9167; 0000-0002-0709-0331
In this case report, we present the coexistence of eccrine porocarcinoma (EPC) and renal cell carcinoma (RCC) in a 69-year-old male patient whose surgical resection pathology of the skin lesion in the right gluteal region was reported as EPC and concurrent radical nephrectomy pathology of the right renal mass was reported as RCC

(2014) Demirci, Gulsen Tukenmez; Aydingoz, Ikbal Esen; Mansur, Ayse Tulin; Atis, Guldehan; Altunay, Ilknur Kivanc
BACKGROUND: Previous studies have shown that some viral infections may be triggers for autoimmune diseases. The role of viral infections in the etiopathogenesis of pemphigus has also been investigated. OBJECTIVES: To investigate the relationship between pemphigus and the hepatitis B and C virus infections. METHODS: This retrospective study included 62 patients with pemphigus and 50 healthy controls of matching ages and genders. The control group included relatives who accompanied the orthopedic patients to the hospital but had no history of systemic and/or autoimmune diseases. RESULTS: The group of patients with pemphigus was composed of 43 (69.3%) females and 19 (29.7%) males, and the mean age was 48.08 +/- 15.38. The hepatitis C virus antibody was negative in all of the patients. Hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), or both, were studied in 44 of the 62 patients. Two (4.3%) of these patients were positive for HBsAg and found to have HBV infection. Fourteen of them were HBsAb positive. Two (4%) of the 50 control subjects showed hepatitis C virus antibody positivity, while only 1 (2%) patient with pemphigus displayed HBsAg positivity. There was no statistically significant difference between the two groups for hepatitis B and C virus infections. CONCLUSIONS: This study does not support an association between pemphigus and hepatitis B and/or C virus infections.

Riga-Fede disease like ulcers in old age: A case report
(2019) Mansur, Ayse Tulin; Deniz, Kagan; Ozdemir, Kerem
Riga-Fede disease (RFD) is a traumatic, reactive benign disorder characterized by persistent ulceration on the tip or ventral surface of the tongue, seen mainly in infants and children. Lesions tend to develop after the eruption of natal or primary incisors, resulting from repetitive traumatic damage due to backward and forward movements of the tongue over the lower incisors. A literature survey has revealed a very limited number of reported cases of RFD in adults. Herein we reported a 70-year-old female patient who developed RFD-like ulcers on the tongue and buccal mucosa during the previous two months, while under treatment of dental implants. Histopathological examination and direct immunofluorescence of the ulcers and periulcer area did not yield a specific diagnosis. The lesions were resistant to systemic steroid treatment, however, after applying for a soft dental plate nightly for protection of the tongue and buccal mucosa, all ulcers completely healed in two months. With regard to the presented patient, we have reviewed the cases of RFD or RFD-like ulcers reported in adults and discussed the factors contributing to ulcer formation in our patient.
Terra Firma-Forme Dermatosis Misdiagnosed as Nevoid Acanthosis Nigricans
(2017) Demirci, Gulsen Tukenmez; Mansur, Ayse Tulin; Demiralay, Ebru; 0000-0002-9646-0719; 28930108; D-6031-2017
Terra firma-forme dermatosis (TFFD) is a clinical condition characterized by brown-gray, velvety, pigmented patches or plaques, resembling dirt on the skin. Nevoid acanthosis nigricans (NAN) is a rare and recently described form of acanthosis nigricans occurring during childhood or early adulthood. Herein we describe a patient with TFFD, initially misdiagnosed as NAN. The patient had developed hyperkeratotic and hyperpigmented plaques on and around the umbilicus during pregnancy. Though regular in bathing practices, she could not clear away the lesions and concerned marks for inesthetic appearance. Histopathological findings were compatible with NAN, and she was prescribed 10% urea lotion. On a dramatic healing after 3 weeks, a diagnosis of TFFD is considered and confirmed by the lesions getting wiped away by vigorous rubbing with alcohol pads. We discuss the key points of differentiating TFFD from NAN, and underline the importance of alcohol test for accurate diagnosis.
