    Background and Design: Our aim was to find out the ratio of cutaneous metastatic tumors among all cutaneous and skin appendage tumors and to establish their clinical characteriaMaterial-methods: We scanned the histopathological diagnoses of all the skin tumors records from the archives between 2006 to 2012 and recorded the age, gender, the diagnosis of internal malignancy, the type of cutenous lesion, the location and the period between the appearance of the primary malignancies and cutaneous metastases.Results: We found that 20 (0,48%) out of 4126 skin tumors were diagnosed as cutaneous metastatic tumors. Ten of the patients were men and ten of them were women ( median age of 51,3±18,34). When considered primary internal malignancies of these patients 6 patients with gastroenterologic malignancy, 4 patients with lung cancer, 4 patients with breast cancer, 3 patients with malignant melanoma, 1 patient with Ewing sarcoma, 1 with acute myeloblastic leukemia and 1 with prostatic cancer were diagnosed. The clinical appearance of the tumors were as follows; 14 nodule, 2 eczematized plaque, 2 papule, 1 papulonodule, 1 infitrated plaque. The localizations of the cutaneous metastatic tumors were as follows; 7 lesions on the anterior trunk, 5 lesions on the abdominal wall, 2 lesions on the back, 2 lesions on the thigh, 2 lesions on the scalp, 1 on the anterior arm, 1 on the inguinal site. We found that 3 patients (15 % ) attended with cutaneous metastatic tumors before the diagnosis of internal malignancies while 17 patients (85 %) attended 18,97±24,76 months (1,5 -109 months) after the diagnosis of internal malignancies.Conclusion: Cutaneous metastatic tumors are rarely seen skin lesions. We found that cutaneous metastatic tumors are mostly nodular and with trunk localization. It is important to recogniza these tumors, because they address primary internal tumo

    Signet cell carcinoma, which is a subtype of adenocarcinoma, usually originates from the stomach. However, it can also originate from the colon, rectum, gallbladder, pancreas, urinary bladder, and breast. We represent a 19-year-old boy diagnosed with signet cell tumour while he was being evaluated for an initial diagnosis of inflammatory bowel disease

    Histologic and biomechanical evaluation of the effects of social stress and the antidepressant fluoxetine on tendon healing in rats

    WOS: 000410008900010PubMed ID: 26578832Impaired wound healing in humans under psychological stress and the positive effects of antidepressant drugs on wound healing were also shown in the literature. However, there are currently no studies regarding the effects of antidepressant drugs on tendon healing. The aim of this study was to compare tendon healing under normal conditions versus social stress. We also aimed to perform a histological and biomechanical analysis of the effects of the antidepressant drug fluoxetine on tendon healing. Sixty Sprague Dawley rats were divided into six groups. A social stress regimen was used to stress the rats. The use of fluoxetine in the social stress group yielded significantly better biomechanical results and the collagen organizations of the fluoxetine group were more similar to the normal tendon collagen organization. Fluoxetine seems to inhibit the negative effects of stress on tendon healing and seems to improve tendon healing

    A Rheumatoid Nodule of the Hand, an Important and Rare Differential Diagnosis of Swellings of the Hand: Case Report and Literature Review

    Swellings of the hand are commonly encountered in a general practice setting and include a multitude of diagnoses. Although majority of these lesions are benign, a specific diagnosis should be achieved for an appropriate treatment. We present a case of a very unusual rheumatoid nodule on the palmar aspect of the hand, but without any rheumatological disease, which was initially misdiagnosed as a tendon sheath tumor. The nodule was successfully treated by surgical excision. The patient made an uneventful recovery, did not experience progression to rheumatoid arthritis (RA), and showed no recurrence during the one-year follow-up. We suggest that when dealing with patients with a hand mass, a rheumatoid nodule should be considered as a differential diagnosis. Understanding the cutaneous expressions of RA can enable early diagnosis, prompt treatment, and lower morbidity and mortality for the affected persons

    This study aimed to investigate the protective effect of ozone therapy on ovarian reserve, number of ovarian follicles, ovarian morphology in a rat ischaemia reperfusion (IR) injury model. Twenty-four, Wistar Hannover rats were included. The rats were divided into three groups as control, detorsion-only, and ozone therapy + detorsion groups. There was a statistically significant difference in the follicular damage and inflammation scores between the study groups (p = .019, p = .002, respectively). The highest AMH decrease was observed in the detorsion-only group (p = .012). The total damage score was higher in the detorsion-only group than the ozone therapy + detorsion group. Preantral, small and large antral follicle numbers were less in the detorsion-only group than the ozone therapy + detorsion group. The highest postoperative day 7 TAS level was in the ozone therapy + detorsion group. TOS levels did not differ significantly between the study groups. The combination of the ozone therapy with ovarian detorsion is more effective in protecting the ovarian reserve than ovarian detorsion-only.Impact Statement What is already known on this subject? Adnexal torsion is a common gynecological emergency in reproductive-age women. The recommended management is the detorsion of the adnexal pedicle in patients with fertility desire. What do the results of this study add? The combination of the medical ozone therapy with conventional surgical ovarian detorsion is more effective in the protection of the ovarian reserve compared to surgical ovarian detorsion. What are the implications of these findings for clinical practice and/or further research? This study speculates that medical ozone therapy in addition to conventional surgical ovarian detorsion could preserve ovarian reserve and function if confirmed in further clinical studies

    Epithelialization process of free fascial flaps used in reconstruction of oral cavity mucosa defects in dogs

    WOS: 000220063500017PubMed: 15108883Bare free fascial flaps are increasingly used for restoration of soft-tissue defects of the oral cavity because they provide thin, foldable tissues with high epithelialization capacity to preserve local anatomy as well as chewing, phonation, and deglutition. However, there are unanswered questions regarding the epithelialization process and other histopathologic changes occurring after transfer of these flaps into the oral cavity. To investigate these changes thoroughly, an experimental study was conducted in the dog model. Bare dorsal thoracic fascia was used as the free flap model. Ten adult dogs were used in this experiment. Oral mucosa defects measuring 6 x 5 cm were created. Free dorsal thoracic fascia flaps were harvested. The vascular pedicle of the fascia flap was anastomosed with the superior thyroidal artery and external jugular vein. Then, the flaps were transferred into the mucosa defects. The dogs were divided into groups, each composed of two animals. At 7, 14, 21, 30, and 60 days postoperatively, general anesthesia was administered to the groups 1, 2, 3, 4, and 5, respectively. First, clinical assessment was performed; then specimens were obtained. Initially, the flaps were gradually infiltrated by acute inflammatory cells coming from the circulation and then replaced by granulation tissue. Epithelial cells deriving from wound margins migrated onto the granulating flaps with eventual coverage of highly organized epithelium after 4 weeks, and the fascia flap could not be differentiated from the native mucosa. The flaps were replaced by normally maturated fibrous tissue containing regular collagen fibers, instead of atypical scar tissue. Wound contraction was calculated as 18 percent at postoperativc day 60. It was detected that bare free fascia flaps used in the repair of mucosa defects act as a scaffold and complete epithelialization from surrounding margins. They can be accepted as the main surgical option for the reconstruction of oral cavity mucosa defects
