Verrucous carcinoma (VC) is an uncommon, distinct type of well-differentiated squamous cell carcinoma. Here we present two cases of VC, one arising from the lower leg and the other from genital skin. Case 1, a female patient, aged 95 years, had a brownish verrucous plaque on her right lower leg. Histopathologically, epithelial tumor cells grew pushing the stroma, while the basement membrane was intact. No prominent cellular atypia or hyperchromatin was found. Case 2, a male patient, aged 53 years, had a verrucous plaque at the border between his scrotum and inner aspect of his thigh...

AIMS: Current WHO classification defines smooth muscle tumors of uncertain malignant potential (STUMP) as neoplasms that cannot be diagnosed reliably as benign or malignant using generally accepted criteria. This has led to application of various criteria sets; consequently, consistent and reliable outcome data is lacking. The aims of this study were: 1) to compare the frequency of adverse outcome in STUMP based on enhanced criteria; and 2) to perform failure analysis to identify feature(s) helpful in predicting outcome...

PURPOSE: Radial scar's stellate appearance may mimic carcinoma mammographically and histologically. Management of radial scar (RS) found on breast core needle biopsies (CNB) ranges from excision to clinical observation due to the variation in reported upgrades to malignancy at surgical excision. We examined the upgrade rate in patients with RS detected on CNB at our institution and reviewed the current literature. METHODS: A retrospective study was conducted of all cases with RS diagnosed on CNB between December 2006 and March 2017 at our institution...

Background: Fine-needle aspiration cytology (FNAC) of thyroid is the initial screening test for thyroid nodules. The Bethesda system classifies thyroid FNAC into six categories. Each category is linked to a malignancy risk and has a recommended clinical management. The aim of this study is to analyze the thyroid cytology smears by Bethesda system and to correlate the diagnosis of cytopathology with histopathology, whenever surgery was done. Materials and Methods: This study presents our experience with the Bethesda system in 681 thyroid FNAs from 632 patients in the period between January 2013 and December 2016...

BACKGROUND: Diagnostic hemithyroidectomy (HT) is the most widely recommended surgical procedure for a nodule with indeterminate cytology; however, additional details may make initial total thyroidectomy (TT) preferable. We sought to identify patient-specific factors (PSFs) associated with initial TT in patients with indeterminate thyroid nodules. METHODS: Retrospective analysis of all patients with a thyroid nodule ≥ 1 cm and initial cytology of atypia of undetermined significance or suspicious for follicular neoplasm between 2012 and 2015 who underwent thyroidectomy...

PURPOSE: Peritoneal mesothelial cysts (PMC) are a clinical dilemma because of their true pathogenic nature. Many definitions have been associated with PMC, including "benign multicystic mesothelioma", "cystic mesothelioma", "multilocular peritoneal inclusion cysts", ''inflammatory cysts of the peritoneum" or "postoperative peritoneal cyst". METHODS: We herein performed a systematic review of the literature focusing on clinical and histopathological aspects of PMC, diagnosis, and therapies...

INTRODUCTION: Fine-needle aspiration (FNA) is a cornerstone in diagnosing thyroid nodules. For decades, Danish FNA has been categorised into the groups: "FNA not performed", "Inadequate", "Cystic", "Inconclusive", "Benign", "Suspicious", "Malignant" and "Information missing". Internationally, The Bethesda Classification System (TBCS) is increasingly accepted, especially owing to a detailed specification of FNA suspicious for malignancy...

Endometrial hyperplasia (EH) is a pathological condition characterised by hyperplastic changes in endometrial glandular and stromal structures lining the uterine cavity. Endometrial hyperplasia, particularly with atypia, is a significant clinical concern because it can be a precursor of endometrial cancer. Accurate diagnosis of precancerous lesions of the endometrium and exclusion of coexisting endometrial carcinomas are absolutely required for the optimal management of patients. The classification of endometrial hyperplasia has had numerous terminology...

Intraductal tubulopapillary neoplasm is a rare tumor that the World Health Organization recognized in 2010 as a subtype of premalignant pancreatic neoplasms. It is important to distinguish it from other intraductal neoplasms, including intraductal papillary mucinous neoplasm, pancreatic ductal adenocarcinoma, and intraductal variant of acinar cell carcinoma, because intraductal tubulopapillary neoplasm has a favorable prognosis. Histopathologically, intraductal tubulopapillary neoplasms are characterized by tubulopapillary growth, uniform high-grade cytologic atypia, frequent necrotic foci, evident ductal differentiation, and absence of mucin...

BACKGROUND: Actinic keratosis (AK) may show extension down follicules, not only in cases with full-thickness epidermal atypia ("bowenoid" AK), but also in cases with atypia limited to the epidermal basalis. Previous studies have demonstrated that in bowenoid AK, follicular extension is usually superficial, being limited to the upper follicular segment. Little is known about the depth of follicular involvement in cases of iSCC arising from AK and the role of the follicle in iSCC pathogenesis...
