(2015) Atalay, Figen; Demirci, Gulsen Tukenmez; Bayramgurler, Dilek; Atesoglu, Elif Birtas; Yildiz, Semsi; 25825579
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a distinct and rare neoplastic entity and was classified as a subgroup of acute myeloblastic leukemia by the WHO in 2008. The median survival of patients was 15.2 months in a large case series. Allogeneic or autologous bone marrow transplantation has been recommended by some reports because of the disease's poor prognosis. We present three patients who presented with both skin and bone marrow infiltration. A 57-year-old man, a 62-year-old woman, a 64-year-old man were admitted to our outpatient clinic because of skin lesions. All of the patient's had bone marrow infiltration with positivity of the CD4, CD56, and CD123 staining. Survival of the patient's were 42, 6 and 12 months, respectively. Two of the patients who presented as blastic form didn't respond to any chemotherapy. BPDCN is a difficult disease to diagnosis and manage. CD4, CD56, CD123, CD303, and T cell leukemia/lymphoma 1. Cutaneous lesions can present as isolated nodules, macules, and disseminated macules and nodules. Positivities are crucial to the diagnosis of the disease in histological examination. Bone marrow infiltration or disease relapse at presentation were related to poor prognosis. Complete immunocytochemical staining must be performed for all patients who have cutaneous lesions with or without blood count abnormalities. Bone marrow (allogeneic or autologous) transplantation should be considered at the first remission.

(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
A case of elephantiasis nostras verrucosa treated successfully by a new type of compressive garment
(2020) Mansur, A. Tulin; Ozker, Emre; Demirci, Gulsen Tukenmez; 32981199
Elephantiasis nostras verrucosa (ENV) is a clinical manifestation composed of hyperkeratotic, verrucous, and papillomatous lesions and dermal fibrosis, which complicate chronic lymphedema. There is currently no cure for ENV, however, several measures have been used to reduce lymphedema and the resultant pseudoepidermal hyperplasia. Supportive dressings and compression therapy still constitute an important part of the treatment. In this report, we present a 69-year-old male patient with ENV developed due to chronic lymphedema caused by venous insufficiency. After failure of healing with conventional two- and three-layered bandages, and elastic stockings, he was successfully treated by a new type of compression garment. We recommend this user friendly garment for prevention of frictional trauma, contact dermatitis, and secondary infection, which all may complicate compression treatments.

(2016) Demirci, Gulsen Tukenmez; Mansur, A. Tulin; Ozker, Emre; Demiralay, Ebru; https://orcid.org/0000-0002-9646-0719; 26894780; D-6031-2017
Nodular cystic fat necrosis (NCFN) is characterized by mobile subcutaneous nodules composed of necrotic adipocytes encapsulated by fibrous tissue. The classical presentation of NCFN is solitary or multiple, up to 40, discrete nodules scattered usually on the extremities or trunk. Here, the authors present an elderly woman who developed an unusual and striking clinical picture of NCFN, two months after a fall. The patient had a large indurated plaque and subcutaneous nodule with superposing necrotic ulcers. During debridement of the ulcers, nearly 100 small nodules popped up freely along with a brownish discharge. Deep in the ulcer, the authors discovered a dislocated nail that belongs to an old hip prosthesis. Histopathological findings of the nodules were compatible with NCFN.

(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.

(2014) Demirci, Gulsen Tukenmez; Mertsoylu, Eda; Altunay, Ilknur Kivanc; Atis, Guldehan; Kucukunal, Asli
Background and Design: To investigate the rate of hypertrichosis and menstrual irregularity in female patients receiving isotretinoin treatment. Materials and Methods: In our study, we included female acne patients who were started isotretinoin treatment and who had no history of menstrual irregularities and hypertrichosis within 6 months prior to isotretinoin use and had no any systemic disease and did not take any medicine except isotretinoin. They were started 0.5-0.8 mg/kg isotretinoin treatment and followed by routine laboratory tests until the total cumulative dose of isotretinoin therapy was completed. They were controlled if they had menstrual irregularity or hypertrichosis after starting isotretinoin. Results: Fifty-six patients were included in the study. The mean age of the patients was 24.91 +/- 5.72 years. The mean treatment period was 6.28 +/- 0.56 months. We found that 16 of 56 (28.8%) patients had menstrual irregularity. Six patients had prolonged interval (delay), -4, hypomenorrhea, -2, hypomenorrhea and prolonged interval, -2, metrorrhagia, - 1, shortened interval, and 1 patient had missed period. Of the 56 patients, 11 patients (23.8%) had hypertrichosis. 5 (45.45%) patients with hypertricchosis were found to have also menstrual irregularity while 5(31.25%) of 16 menstrual irregularity patients were found to have hypertrichosis. Nine patients reported having a stressful life event. One of them were both had menstrual irregularity and hypertrichosis, 2 of them had only hypertrichosis, 2 of them had only menstrual irregularity and 4 of them had no more finding. Conclusion: Our study showed that the complaints of menstrual irregularity and hypertrichosis may develop during isotretinoin therapy. Based on this result, we assume that further laboratory tests and controlled studies investigating the effects of isotretinoin on hormones are needed.
Is It A Sarcoidal Foreign-Body Granuloma or A Cutaneous Sarcoidosis on A Permanent Eyebrow Make-Up?
(2016) Demirci, Gulsen Tukenmez; Mansur, A. Tulin; Yildiz, Semsi; Guelec, A. Tulin; https://orcid.org/0000-0002-9646-0719; 26073118; D-6031-2017
Permanent make-up is a kind of cosmetic tattoo in which the colorants (pigments) are deposited in dermis after piercing the skin by tiny solid needles. It may cause some adverse effects such as local inflammation, infection, and allergic reactions on the skin and even systemic adverse effects such as sarcoidal reactions. Here the case of a 34-year-old woman who has some yellowish hard shiny papules on her eyebrows after having a permanent make-up is described. The histopathological examinations of the papules are diagnosed as sarcoidal foreign-body reactions. All the laboratory investigations were in normal limits except a mild elevation in angiotensin converting enzyme or ACE level. The lesions mostly improved after topical corticosteroid treatment. Sarcoidal foreign-body reaction due to permanent make-up is discussed with this presentation.

(2016) Solak, Sezgi Sarikaya; Altunay, Ilknur Kivanc; Demirci, Gulsen Tukenmez; Can, Burce; https://orcid.org/0000-0002-9646-0719; 26171599; D-6031-2017
Objective There are limited reports studying on congenital cutaneous anomalies in newborns, particularly in Turkey. Some of congenital cutaneous anomalies serve as an important clue for accompanying syndromes or other medical conditions. This study aimed to determine the prevalence of congenital cutaneous anomalies in newborns and to discuss their clinical significance with a brief review of literature. Study Design A total of 1,000 newborns were examined by a dermatologist in a hospital-based, cross-sectional, prospective study between October 2011 and April 2012. Results We observed 11 different congenital cutaneous anomalies in 48 newborns of 1,000 (4.8%). The most commonly seen anomalies were sacral dimple, accessory nipple, acrochordon, hypospadias, open spinal dysraphism, and accessory tragus. None of the newborns with cutaneous anomalies had any association. Conclusions Although congenital cutaneous anomalies are rare in newborns, clinicians should be aware of them as they may be in association with syndromes and other medical conditions. It is also important to give appropriately provided information to avoid parents concerns.
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.
