Yayın Case report: presentation of pleomorphic liposarcoma arising in a borderline phyllodes tumor(Elsevier Ltd, 2018) Polat, Yalçın; Arslan, Gözde; Kebudi, Abud; Apa, Duygu DüşmezThe stromal component of Phyllodes tumors represents the neoplastic portion of the lesion. A variety of associated malignancies can arise from PTs, with its dual population of cells. Presentation of case: We share a very rare case of “borderline”breast phillodes tumour with a 75% liposarcoma component. A 48-year-old woman presented at the surgical clinic with a mass in the left breast. On mammograms, the lesion was dense with radiolucent areas inside which were thought to be compatible with fat. The mass was assumed to be breast imaging-reporting and data system (BIRADS) 3 on sonography as it was well contoured. The needle biopsy was reported to be consistent with a fibroadenomatous lesion. The lesion was completely excised. On microscopic examination, the lesion has benign mammary duct epithelium lining the slit-like spaces. The stroma composed of fibrous and adipous tissue. The fibrous part was cellular, and several cells appeared bizarre. Adipous tissue replaced most of the stroma and was diagnosed as pleomorphic liposarcoma. Discussion: According to the 3 tiered grading criteria of PTs, our case normally suits in borderline category, without liposarcoma component. Heterologous sarcomatous elements usually accompany high grade PTs. Rare cases of benign and borderline PTs with sarcoma component have been reported. Conclusion: The presence of a malignant heterologous component places the tumour into the malignant category regardless of other histological features. © 2018Yayın Finding the underlying cause of thoracic outlet syndrome / Torasik outlet sendromunun nedenini bulmak(Maltepe Tıp Dergisi, 2016) Arslan, Gözde; Cubuk, RahmiCervical rib is an extra rib arising from the 7th vertebra. It is estimated to occur in 0.6% (1 in 150 people) to 0.8% of the population. It may compress the nerves and vessels and cause thorasic outlet syndrome. Cervical rib is diagnosed by Computer Tomography (CT). 3D CT images are very helpful for the correct diagnosis. Treatment is surgical most of the time. Symptoms usually diminish dramatically after surgery.Yayın Intraductal Papilloma of Buccal Mucosa Minor Salivary Gland Orig(2020) Düşmez Apa, Duygu; Arslan, Gözde; Polat, Yalçın; Yalçın, Özben; Vural, Çetin; Kulduk, GamzeDuctal papillomas are rarely seen in salivary glands. They are largely classified under the term “ductal papillomas” and generally further categorized as intraductal papilloma, sialadenoma papilliferum, and inverted ductal papilloma. Intraductal papilloma, which usually arises from the major lactiferous duct and localized in minor salivary glands, is an uncommon lesion. We report a case of intraductal papilloma of the buccal mucosa.Yayın Paranasal sinus metastases, two cases / Paranazal sinüs metastazları, iki olgu(Maltepe Tıp Dergisi, 2016) Arslan, Gözde; Boyacı, Zerrin; Cubuk, RahmiSinus metastases is rare and not expected most of the time. It is usually misdiagnosed as sinusitis and the true diagnosis is delayed. Clinicians and radiologists should be aware of this possibility especially for cancer patients. On this article, we aim to present 2 cases with sinus metastases with radiological findings and figures.Yayın Quantification of the Asymmetry between Right and Left Cerebral Lateral Ventricles by Indexing Methods(Wolters Kluwer Medknow Publications, 2020) Arslan, Gözde; Özdemir, Nur Betul UnalPurpose: To retrospectively analyze hydrocephalus and lateral ventricular asymmetry by measuring the midline shift, Evans index, right and left semi-Evans index, Right and left semi-callosal angles, superior ophthalmic vein (SOV) diameters, and to compare these findings with the control group. Methods: The study included 93 cases with hydrocephalus, 80 cases with asymmetrical lateral ventricles (ALV) and 83 control cases with normal findings who had cranial magnetic resonance imaging (MRI) in our institute between the years 2011 and 2016. A senior and junior radiologist analyzed the images and performed the measurements, and the results were compared. Results: The cut-off points for the Evans index and right and left semi-Evans indexes for differentiating hydrocephalus and ALV were calculated as 28.68%, 30.77%, and 30.88%, respectively. The septum shift degree was significantly higher in the ALV group compared to the control group (P = 0.010; P < 0.05). ALV or hydrocephalus were not found to be associated with SOV enlargement. The SOVs were not found to be enlarged ipsilateral to asymmetrically enlarged lateral ventricle. Conclusion: Lower Evans and right and left semi-Evans indices are seen in ALV. Despite some limitations, the Evans index could still be used to differentiate hydrocephalus and ALV. Mild ALV is mostly associated with an off-midline septum. SOV diameter and enlargement are not indicators of hydrocephalus or ALV.
