Objectives: Respiratory cytology specimens such as bronchoalveolar lavage (BAL) and bronchial wash (BW) obtained using a fiberoptic bronchoscope are very useful in detecting or ruling out various inflammatory conditions, infections, and neoplastic lesions. A study was carried out to determine the usefulness of respiratory cytology in the diagnosis of pulmonary lesions and the limitations of cytology if any, and correlate the results of cytology with biopsies wherever possible.
Methods: All bronchoscopic cytology and biopsy specimens received at the pathology laboratory of this tertiary care institute between June 2014 and May 2017 were analyzed. Cytology smears were stained with Leishman's stain, hematoxylin and eosin (H and E), Papanicolaou (PAP), and Ziehl-Neelsen (ZN) stain for all cases and special stains wherever needed. Slides prepared from biopsy specimens were stained with H and E. Immunohistochemistry was used for confirmation and further typing of malignant lesions and diagnosis rendered was compared with the corresponding cytology diagnosis.
Results: A total of 120 specimens of BAL or BW cytology with or without biopsy were analyzed. Thirty-three were diagnosed as non-specific inflammatory lesions. The most common malignancy diagnosed by cytology was adenocarcinoma followed by squamous cell carcinoma. Correlating BAL with biopsy specimens, the sensitivity, specificity, and diagnostic accuracy of BAL were 100%, 88.8%, and 91.6%, respectively. Correlating BW with biopsy specimens, the sensitivity, specificity, and diagnostic accuracy of BW were 85.6%, 85.6%, and 85.6%, respectively.
Conclusions: Accurate diagnosis can be made from the examination of bronchoscopic cytology specimens in pulmonary inflammation, tuberculosis, fungal infections, and malignancies. Combining respiratory cytology with biopsy and ancillary techniques can aid in better subtyping of neoplastic lesions.

Surgical resection is the only curative treatment for cholangiocarcinoma, but it is often diagnosed at advanced stages, making surgical resection infeasible. Recently, the concept of conversion surgery has expanded the indications for surgical treatment, thanks to advancements in both perioperative management and chemotherapy. However, it remains unclear which patients benefit most from this treatment strategy.

Background And Study Aims: Diffuse infiltrative gastric cancer can be difficult to diagnose owing to a lack of endoscopic features in the superficial mucosa. Moreover, a forceps biopsy may not reveal a pathological diagnosis. We aimed to evaluate the diagnostic yield and safety of endoscopic mucosal resection (EMR) and 'open-lid submucosal biopsy', a technique wherein EMR followed by biopsy of the ulcer floor is performed for a pathological diagnosis.

Background: Neuroendocrine tumors primarily consist of endocrine cells commonly located in neural tissue and the endocrine system. Primary neuroendocrine neoplasms of the breast are highly heterogeneous tumors characterized by a diverse cell population. Their rarity in the breast poses considerable challenges in studying their pathogenesis and developing effective treatments.

Background: Male breast cancer (MBC) is a rare malignancy, but its global incidence has shown a notable increase in recent decades. Factors such as limited health literacy, inadequate health education, and reluctance to seek medical attention contribute to the late-stage diagnosis of most MBC patients. Consequently, there is an urgent need for a highly specific and sensitive diagnostic approach to MBC.

RBM family proteins plays the critical role in the progression of numerous tumors. However, whether RBM family proteins involved in prostate cancer (PCa) progression is remain elucidated. In our study, an RNAi screen containing shRNA library targeting 54 members of the RBM family was applied to identify the critical RBM proteins involved in prostate cancer progression under docetaxel treatment, and RBM19 was selected.
