Retroperitoneal Malignant Fibrous Histiocytoma Can Mimic a Hydatid Cyst
Malignant fibrous histiocytoma is the second most common soft-tissue sarcoma in adults. After the extremities, the retroperitoneal space is the second most common site of this tumor. A 50-year-old man presented with a right retroperitoneal, thick-walled, cystic multilocular mass measuring 10 × 10 cm that was thought to be a type CE 5 hydatid cyst preoperatively. However, the postoperative histopathology did not agree with the radiological findings and instead showed a malignant fibrous histiocytoma. The computed tomography and ultrasound/Doppler ultrasound findings of this retroperitoneal mass mimicked a type CE 5 hydatid cyst. We present this case because the surgical management of these two lesions differs and misdiagnosis can be problematic

Clinical and histopathological characteristics and differential diagnosis of chordomas
Purpose: Chordomas are rare malignant bone tumours occuring in the midline of axial skeleton. We aimed to assess these tumors which has been diagnosed in our center in terms of clinical and pathologic characteristics, and differantial diagnosis difficulties.
Material and Methods: We retrospectively evaluated cinical and histopathologic characteristics of 10 chordoma patients diagnosed at pathology department of Baskent University Adana Teaching and Resarch Hospital between 2009 and 2014.
Results: The patients were consisted of men (n= 9) and women (n= 1) with the age of 61.3 (38-84) years old. The localization of chordomas were the sacrococcygeal region at eight patients (80%), lumbar vertebrae at one patient ( 10%) and clivus at one patient (10%). The mean diameter was 4.68 (2.5-7.5) cm. Histopathologically, majority of cases were "conventional chordoma" while one of them was "chondroid chordoma". Surgical excision was performed for all patients, only one case has recieved radiotherapy, and chemotherapy was given after surgery for one patient. Local recurrence was detected in three patients and distant metastasis (lung) was found in a patient and he died in a short time.
Conclusion: Because that chordomas are rare clinical bone tumours which can be treated efficiently by appropriate surgical excision, clinical and histopathological characteristics and differential diagnosis should be well known

A rarely seen diffuse parenchymal lung disease: diffuse pulmonary meningotheliomatosis
Pulmonary meningothelial- like nodules (MLNs) are usually detected incidentally during pathologic evaluation of resected pulmonary parenchymal specimens and autopsies. These nodules are generally asymptomatic and most often single. Diffuse pulmonary involvement by MLNs is less frequently described. MLNs are benign lesions and have been associated with neoplastic and non-neoplastic pulmonary conditions and occasionally with extrapulmonary diseases. We report a case of a female patient presenting with multiple and bilateral pulmonary nodules diagnosed with "diffuse pulmonary meningotheliomatosis" by video-assisted thoracoscopic surgery (VATS). Diffuse pulmonary meningotheliomatosis should be included in the differential diagnosis of diffuse bilateral lung nodules in the radiologic studies
Venous thrombosis of sarcoidosis as an unusual incidental finding on 18F-fluorodeoxyglucose positron emission tomography/computed tomography
Sarcoidosis is defined as a multisystem granulomatous disorder of unknown cause. Venous thrombosis (VT) in the sarcoidosis is rare. The routine use of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has resulted in clinicians detecting many incidental findings, which have proven to be clinically significant such as thrombosis. Here, we present a case with VT of sarcoidosis in the inferior vena cava and portal vein as an unusual incidental finding on 18F-FDG PET/CT
Myofibroblastoma of the Breast
This study aimed presenting a case of a 64-year-old woman with a rare diagnosis of myofibroblastoma (MFB). MFB is one of the rare, benign, spindle-like stromal tumors arising from the connective tissue of the breast. MFBs are often confused with fibroadenomas and hamartomas because of their benign characteristic appearance on breast imaging and are diagnosed after excisional biopsies. Their differential diagnosis with malignant neoplasia of the breast is important because of their wide morphological spectrum. Our case also demonstrated a breast mass with benign imaging characteristics and a needle core biopsy revealing a benign, spindle-like stromal tumor. The pathological examination performed after the excision of the lump demonstrated a collagenous-/fibrous-type MFB. This case report emphasizes the rare but important place of MFB variants of the breast in the differential diagnosis of breast mass
