Histopathology is the fundamental tool of pathology used for more than a century to establish the final diagnosis of lung cancer. In addition, the phenotypic data contained in the histological images reflects the overall effect of molecular alterations on the behavior of cancer cells and provides a practical visual reading of the aggressiveness of the disease. However, the human evaluation of the histological images is sometimes subjective and may lack reproducibility. Therefore, computational analysis of histological imaging using so-called "artificial intelligence" (AI) approaches has recently received considerable attention to improve this diagnostic accuracy...

BACKGROUND: Inflammatory bowel diseases may be associated with many extraintestinal complications, that in some cases can represent the first onset of these disorders. In particular during the course of the disease, Ulcerative Colitis develops extraintestinal manifestations very frequently. One of the rarest is pyoderma gangrenosum, a noninfectious neuthrophilic dermatosis, that can involve most commonly legs but also other parts of the skin or mucosas. It can be idiopathic or associated with gammopathies, vasculitis, chronic arthritis or, like in our case, with inflammatory bowel disease and malignancies...

Vulvovaginal atrophy accompanied by lower urinary tract dysfunction related to low levels of estrogen and androgens is labeled as genitourinary syndrome of menopause (GSM). Although this condition affects most postmenopausal women worldwide, it seems to be underdiagnosed and undertreated. Women should be properly advised to choose an adequate treatment modality to improve their quality of life, sexual relationships and social activity. The aim of this article is to increase knowledge of GSM. The current treatment options, both hormonal and non-hormonal, are reviewed...

Accurate profiling of tumors using immunohistochemistry (IHC) is essential in cancer diagnosis. The inferences drawn from IHC-stained images depend to a great extent on the quality of immunostaining, which is in turn affected strongly by assay parameters. To optimize assay parameters, the available tissue sample is often limited. Moreover, with current practices in pathology, exploring the entire assay parameter space is not feasible. Thus, the evaluation of IHC stained slides is conventionally a subjective task, in which diagnoses are commonly drawn on images that are suboptimal...

OBJECTIVE: As fine needle aspiration cytology (FNAC) is the primary tool for evaluation of breast lesions, it is essential to segregate lesions with low and high risk of malignancy. To address this, Masood proposed a cytological scoring system for categorization, Masood's Scoring Index (MSI), which was modified later (Modified Masood's Scoring Index [MMSI]). This study analyses the effectiveness of MMSI over MSI and assesses the concordance between cytological scoring and histopathology...

Cranial fasciitis (CF) is an uncommon benign myofibroblastic proliferation involving the soft and hard tissues of the cranium. It typically occurs in the pediatric population with a male predilection (male-to-female ratio 1.5:1). The clinical presentation is usually a rapidly expanding, painless nodule. Bone erosion may be appreciated radiographically. Histopathologic sections of CF show plump, fibroblast-like cells with pale, oval shaped nuclei and prominent nucleoli in a fibrous or myxoid background. Growth is self-limited and surgical excision is considered curative...

Cysticercosis is a systemic parasitic disease caused by larval stage of Taenia solium. It is the most common parasitic disease worldwide. It is potentially a dangerous systemic disease with variable clinical manifestations. It can be diagnosed by radiological imaging and serology but demonstration of parasitic larva by cytology or histopathology is still the gold standard. Fine needle aspiration cytology (FNAC) plays an important role in prompt diagnosis of this disease. Aim: To study the role of FNAC in the diagnosis of cysticercosis...
