Pleuropulmonary blastoma (PPB) is a rare primitive intrathoracic malignant neoplasm that occurs almost exclusively in children and adolescents. PPB is classified into three types according to the presence of cystic and solid areas. We report a case of PPB with an intraocular metastasis diagnosed by fine needle aspiration (FNA): 3-year-old female was treated for type II PPB by neoadjuvant chemotherapy and surgery. Four years later, she presented with an intraocular lesion. To differentiate between metastasis or other malignancy, a transcleral FNA was performed and showed two cellular populations represented by roundish malignant cells and spindle-shaped cells. The patient was treated with chemotherapy and diode laser ablation. A year later, the patient had enucleation and rare residual cells were found on the histological specimen. Patient remains disease-free 66 months after the last surgical treatment. Diagn. Cytopathol. 2017;45:156-160. © 2016 Wiley Periodicals, Inc.

Introduction: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used for diagnosing mediastinal lymphadenopathy. Despite a low complication rate, severe hemorrhage can occur which is reported in this literature, particularly in hypervascular conditions like Castleman disease.
Methods: A 54-year-old male with idiopathic multicentric Castleman disease underwent EBUS-TBNA for mediastinal lymph node sampling.

Myofibroblastoma is a rare mesenchymal tumour known for its benign nature but complex diagnostic pathway. A woman in her 40s presented with a painless breast mass, initially reported as a fibroadenoma on ultrasound mammography and as a benign to borderline phyllodes tumour on fine needle aspiration cytology. Contrast-enhanced CT was reported as carcinoma of the breast with Breast Imaging and Reporting Data System (BIRADS)-6.

Protein aggregation, a major concern in biopharmaceutical quality control, can be accelerated by various stresses during clinical handling. This study investigated potential aggregation risk factors during dilution process with syringe handling for intravenous administration. Using γ-globulin and IgG solutions as surrogate models of antibody therapeutics, we examined the effects of high sliding speeds and piston operations of the syringe on protein aggregation during saline dilution.

Objective: To evaluate the feasibility, safety, and efficacy of microwave ablation (MWA) for the treatment of patients with Bethesda IV follicular neoplasms (FNs) (≤3 cm).
Methods: In the retrospective study, patients who underwent MWA for Bethesda IV follicular neoplasms (≤3 cm) were included. Technical success, volume reduction, disease progression, and adverse event (AE) rates were analyzed postablation.
