Predicting pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) in triple-negative breast cancer (TNBC) patients accurately is direly needed for clinical decision making. pCR is also regarded as a strong predictor of overall survival. In this work, we propose a deep learning system to predict pCR to NAC based on serial pathology i...

Background: Although triple-negative breast cancer (TNBC) is associated with an increased risk of recurrence and metastasis, the molecular mechanisms underlying metastasis in TNBC remain unknown. To identify transcriptional changes and genes regulating metastatic progression in TNBC, we compared the transcriptomic profiles of primary and matched m...

Background: Triple-negative breast cancer (TNBC) is a heterogeneous breast cancer subtype with distinct biological features and clinical behavior. TNBC is associated with an increased risk of metastasis and recurrence. In this whole exome study, we investigated the genetic profiles of primary TNBC tumors and paired metastases using next-generation...

Objective: Sacrococcygeal pilonidal disease is a chronic discharging wound that causes pain and loss of quality of life. Phenol application is an outpatient procedure with low complications and low recurrence rates. We evaluated the radiological, histological, and clinical results of phenol application. Methods: A total of 44 consecutive patient...

Background Extramedullary leukemia, also known as myeloid sarcoma, is a rare form of acute myeloid leukemia and often accompanies bone marrow involvement. Myeloid infiltration of the thyroid gland is extremely rare. Here, a unique case in which thyroid cancer tissue was infiltrated with myeloid cells is presented. Case presentation We present a ca...

Myeloid sarcoma of the breast is a rare malignancy, can be seen after bone marrow transplantation. Although there are no specific features for this malignancy which is difficult to diagnose, some common features draw attention in the published case reports. Since there is no consensus on the treatment of myeloid sarcoma of the breast, we aimed to e...

Aim: To assess the presence of isocitrate dehydrogenase (IDH) 1 mutation in glioblastomas using real-time polymerase chain reaction (RT-PCR), which is the gold standard in the diagnosis of IDH1 mutation; by immunohistochemistry (IHC), which is available in most of the pathology laboratories; and by preoperative magnetic resonance imaging, which is...

Background Mantle cell lymphomas are aggressive, mature B-cell neoplasms characteristically showing overexpression of cyclin D1. Although lymphadenopathy is the most common presentation, involvement of extranodal sites including bone marrow, peripheral blood, liver, gastrointestinal system, and Waldeyer ring is also seen frequently. Soft tissue loc...

Introduction Solid variant papillary thyroid cancer (SVPTC) is a rare variant of papillary thyroid carcinoma (PTC) and its prognostic value is still unclear. Therefore, we re-evaluate the histopathological and clinicopathological features of 28 patients with SVPTC in the light of current literature. Material-methods Of the 1308 cases were previous...

Background: The coexistence of two morphologically different tumors attached to each other creates a very rare type of tumor called a collision tumor. Collision tumors containing pituitary adenoma-sellar meningioma have only been described in four cases to date; we discuss a fifth case harboring a collision tumor comprising a pituitary corticotrop...

Primary cancer metastasis to thyroid gland is rare. The most common metastatic tumors of the thyroid gland are from lung, breast and renal cell carcinoma. In this case report, a patient with breast cancer metastasized to the thyroid gland is presented. A 38-year-old female patient was diagnosed with breast cancer, and positron emission tomography-c...

Objective: Paraspinal schwannomas arise from the dorsal nerve root. Symptoms of schwannomas may depend on their locations and sizes. This case was presented by a female patient with a dorsalgia for 10 years. She had not any specific symptoms but pain and a thick spot on the neck (cervical area). Paraspinal schwannomas involve the dorsal nerve roots...

Pauci-immune glomerulonephritis (GN) is more common in elderly people compared to children and the etiology is not completely understood yet. Antineutrophil cytoplasmic antibody (ANCA) positivity occurs in 80% of the patients. We report a case of a 7-year-old girl who presented with malaise and mildly elevated creatinine diagnosed as ANCA-associate...
