OBJECTIVE: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive technique for investigating hilar and mediastinal lymphadenopathy. This study reports eleven cases in which EBUS-TBNA was used to assess mediastinal and hilar lymph nodes for the presence of metastatic melanoma. MATERIAL AND METHOD: A retrospective study was performed of all patients who had a history of melanoma and underwent EBUS-TBNA to assess hilar or mediastinal lymphadenopathy for the presence of metastatic melanoma...

OBJECTIVE: The 2015 WHO classification classifies neuroendocrine tumours (NET) of the lung into typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma and small cell carcinoma based on morphology alone. Mitosis is the major parameter for this classification, and thus several studies have focused on the role of Ki67 in these tumours but without conclusive results. The aim of the study was to categorize neuroendocrine tumours of the lung based on morphology and to assess the utility of Ki67 in diagnosis...

Ceren Boyaci, Kemal Behzatoğlu
OBJECTIVE: Nested variant is bland-looking but aggressive subtype of urothelial carcinoma (UC). Cases having significant muscle invasion do not cause problems but small and superficial biopsies may be challenging due to morphological similarities between nested variant urothelial carcinoma and benign urothelial lesions. MATERIAL AND METHOD: We studied Glucose transporter 1 (GLUT-1), which is an integral membrane protein providing glucose pass through plasma membrane down its concentration gradient, to see if it is useful for the differential diagnosis...

OBJECTIVE: The granulation pattern of pituitary tumors may be important to predict tumor behavior, treatment outcomes, and recurrences. Therefore, we compared densely granulated corticotroph tumor (DGCT) and sparsely granulated corticotroph tumor (SGCT) in terms of clinicopathologic findings. MATERIAL AND METHOD: A total of 41 patients (31 females/10 males) were assessed in the study. The granulation patterns were detected by Periodic Acid-Schiff (PAS) and adrenocorticotropic hormone (ACTH) immunoreactivity...

Filariasis is a major public health problem in tropical countries like India. Despite the large number of people at risk, detection of eggs with or without larva (microfilaria) on fine-needle aspiration cytology is very unusual, especially in an uncommon site or incidentally detected in clinically unsuspected cases of filariasis with the absence of microfilariae in the peripheral blood. A 19-year-old male presented with swelling over medial aspect of left arm (just above the elbow), with no other specific signs and symptoms...

Microsporidiosis is a rare, but emerging opportunistic infection in solid organ transplant and stem cell transplant recipients. Renal involvement in microsporidiosis is very rarely seen in these recipients. We describe two cases of pediatric renal microsporidiosis, diagnosed on renal biopsies, following bone marrow transplantation presenting as severe acute kidney injury. The first patient died, whereas the second survived due to early diagnosis based on high index of suspicion and prompt treatment with Albendazole...

Echinococcosis is a common cause of pulmonary cavities. Aspergillus fumigatus, a saprophytic fungus, can colonise pulmonary cavities caused by tuberculosis, sarcoidosis, echinococcosis, bronchiectasis and neoplasms. Infection by Aspergillus is often seen in immunosuppressed cases. However, co-infection of Aspergillus with pulmonary echinococcosis is unexpected and very unusual, especially in an immunocompetent patient. We present the case of a 45-year-old immunocompetent male who came with non-resolving pneumonia and fever for 8 months and dyspnoea since 15 days accompanied by recurrent episodes of hemoptysis since 5 days...

OBJECTIVE: BRAF is the most common mutation in melanoma. The most common subtype is BRAF V600E, followed by V600K. Initially, the authors aimed to investigate whether clinicopathological features of melanoma are associated with BRAF mutations. We then aimed to present the relationships between the clinicopathological features and the mutated subtype (V600E vs V600K). MATERIAL AND METHOD: 61 patients with metastatic malignant melanoma (affecting the lymph node or other distant sites) were selected...

OBJECTIVE: Although classical Hodgkin lymphoma (cHL) has a relatively good prognosis, it also entails different treatment responses and involves patients who have different clinical courses. Our aim was to investigate c-Myc, Bcl-2 and EBV biomarkers in cHL and their relationship with the IPS score. MATERIAL AND METHOD: c-Myc and Bcl-2 immunohistochemical staining with EBER in situ hybridization (EBER-ISH) was applied to the paraffin sections of 94 cases diagnosed as cHL...

OBJECTIVE: The clinical behavior of gastrointestinal stromal tumors is divergent. The aim of the present study was to define the clinicopathological features that determine the patient's outcome. MATERIAL AND METHOD: Sixty-five gastrointestinal stromal tumors were reviewed with their histological, immunohistochemical and clinical features and compared with their clinical outcome statistically.

OBJECTIVE: Cervical cancer has an increasing incidence in developing countries with a predominance of squamous cell carcinoma. In this work, we aimed to analyze the role of EZH2, Endothelin-1, and CD34 as indicators of the aggressiveness in cervical squamous cell carcinoma. MATERIAL AND METHOD: Immunohistochemical expression of EZH2, Endothelin-1, and CD34 was studied in 54 paraffin-embedded tissue specimens of cervical squamous cell carcinoma. Their correlation to the clinicopathologic features and the potential angiogenic role were analyzed...

REVIEW
Evren Uzun, Sülen Sarioğlu
Molecular pathological analysis has an expanding role in patient diagnosis and management. The performance of these techniques relies on excellent laboratory procedures. However, the crucial step is obtaining the best samples for molecular analysis. Archiving and selection of these are the responsibilities of all pathologists even if they are not working at a center with molecular pathological facilities. This review focuses on the features of different types of materials for molecular pathological analysis...

COMPARATIVE STUDY
Nesreen H Hafez, HebatAllah M Shaaban
OBJECTIVE: Cytomorphologic differentiation of metastatic breast carcinoma from non breast metastases in cytological materials can be difficult. Current breast immunocytochemical markers have low sensitivities. Transcription factor GATA 3 is a promising marker for detecting breast differentiation in cytological materials. The aim of the study was to assess the diagnostic value of GATA 3 as a breast differentiation marker in metastatic cytological materials and to compare it with expression of mammaglobin and gross cystic disease fluid protein-15 (GCDFP-15)...
