We present a 74-year-old male patient with 3-years history of visible discoloration of the glans penis, without subjective complaints. Histopathological examination after incision biopsy revealed a moderate increase in the number of melanocytes in the basal layer with irregular distribution, without melanocytic nests, melanophages in the superficial dermis, and subepidermal sclerosus. No cytologic atypia of melanocytes was detectable. The diagnosis of melanosis of the genitalia in association with lichen sclerosus was made...

Among tumors of the major salivary glands, tumors in the sublingual gland are rare. Although mucoepidermoid carcinoma (MEC) represents a histological type of salivary gland tumor, it is occasionally difficult to diagnose due to its histological variation. The present study reports a case of MEC harboring a mastermind-like transcriptional coactivator 2 (MAML2) gene translocation in the sublingual gland. A 76-year-old Japanese woman with a mass in the left submandibular region was referred to Kurume University Hospital (Kurume, Japan)...

An approximately 10-yr-old adult female whitespotted bamboo shark (Chiloscyllium plagiosum) presented with a smooth, white, irregular, ulcerated, and expansile lesion on the left lateral aspect of the maxillary rostrum. The lesion had short periods of abrupt and rapid proliferation and then remained static for several months. Cytology and culture were nonspecific and did not reveal any discernible etiologic agents or cellular atypia. The lesion was nonresponsive to parenteral antibiotics. One year after the initial onset of the lesion, the ulcer was 10 cm in diameter, a percentage increase in size of 455%...

BACKGROUND: The term "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) has replaced a subset of follicular variant of papillary thyroid carcinoma due to the indolent behavior of such tumors. NIFTPs are most often classified in an "indeterminate" diagnostic category. In the current study, the authors sought to identify cytologic features helpful in distinguishing NIFTP from other entities in these categories, particularly benign nodules. METHODS: The authors retrospectively evaluated a consecutive cohort of 130 thyroid fine-needle aspiration (FNA) specimens with an indeterminate diagnosis and available histopathologic follow-up...

BACKGROUND: Solitary fibrous tumors (SFTs) are rare mesenchymal tumors commonly located in the pleura, soft tissues, or meninges and are characterized by the NGFI-A-binding protein 2 (NAB2)-signal transducer and activator of transcription 6 (STAT6) fusion gene. Recent studies have indicated that nuclear STAT6 immunohistochemistry is a specific marker for SFTs. METHODS: The authors reviewed fine-needle aspiration (FNA) specimens from extracranial SFTs diagnosed at their institution between 1993 and 2017...

Perivascular epithelioid cell tumor (PEComa) is a rare neoplasm considered to arise from myomelanocytic cell lineage. The uterus is reportedly the most common site to be involved. Orbital PEComa is extremely rare with only two cases reported till date. A 5-year-old male presented with a right medial orbital mass for the last 6 months. The patient was diagnosed with alveolar soft part sarcoma elsewhere. Magnetic resonance imaging features were suggestive of lymphangioma with bleeding. The excision biopsy revealed multiple tumor cells comprising epithelioid cells with clear cytoplasm, along with nuclear atypia and mitosis...

BACKGROUND: Lipoblastomas are rare, benign adipocytic tumors that present mostly during infancy. In about 70% of cases, these tumors carry abnormalities in chromosome 8, mainly leading to rearrangements of the PLAG1 gene. METHODS: We report a series of histologically proven lipoblastomas with previous fine-needle aspiration (FNA) cytology from 9 patients (n = 10 samples) and describe their clinical, cytological, and molecular features. RESULTS: Our cohort included 5 boys and 4 girls (median age, 2...

Adenomas of the ampulla of Vater are distinctly rare, representing <10% of periampullary neoplasms. Very few reports of the cytologic features of ampullary adenomas are present in literature, particularly in bile duct brushing samples. A case report and review of the literature is presented. The typical cytologic features of ampullary adenomas on cytologic preparations include tall, thin columnar cells with mildly hyperchromatic elongated nuclei and nuclear pseudostratification, in a relatively clean background...

Objectives: Granular cell tumors are rare neoplasms of neural origin. Despite the mesenchymal nature of these tumors, they rarely occur in the soft tissue, and as a result, this subset is not well characterized. We present the largest case series to date comprising 50 patients with benign and atypical soft tissue granular cell tumors in an effort to better define the pathologic features in this subset of lesions. Methods: All cases of soft tissue granular cell tumors from the Ohio State Medical Center and the Medical College of Wisconsin over a 10-year period were reviewed for histologic and clinical findings...

This article is a review of diagnostic and therapeutic possibilities in common epibulbar malignant tumors, such as basal cell carcinoma, conjunctival lymphoma, squamous cell carcinoma and conjunctival melanoma. Most importantly, for every tumor patient there is a detailed anamnesis, split lamp examination and photo documentation. Further regular controls after therapy are required due to the risk of recurrences.Basal cell carcinoma is the most common tumor of the periocular skin, divided into three subtypes (nodular, superficial and morphea)...

INTRODUCTION: The fine-needle aspiration has a significant role in assessing the malignancy risk of thyroid nodules. There is uncertainty regarding the value of repeat fine-needle aspiration in benign nodules. This study aims to evaluate the concordance of results in consecutive fine-needle aspiration and to study the relevance of repetition in benign results. MATERIAL AND METHODS: Retrospective study of the 4800 thyroid nodules fine-needle aspiration held in Instituto de Patologia e Imunologia Molecular da Universidade do Porto between January 1, 2014 and May 2, 2016...

Ovarian fibromas are benign sex cord stromal tumours occurring in peri-menopausal and post-menopausal women. These tumours are composed of spindle fibroblastic cells producing collagen. They are almost always endocrine-inert and are rarely associated with hormone production. We report herein a case of a 60-year-old Indian woman presenting as post-menopausal bleeding. Imaging studies and endometrial biopsy revealed a right ovarian solid tumour coexisting with thickened proliferative endometrium, other causes of hyperoestrogenism being excluded in the woman...

Extrahepatic bile duct obstruction can be caused by various pathologies, most of them being malignant. Painless, progressive jaundice is the usual mode of presentation. We report a case of distal Common Bile Duct (CBD) obstruction due to a Benign Intramural Beale gland hyperplasia mimicking a periampullary carcinoma. Peribiliary glands (Beale Glands) are a group of seromucinous glands, normally seen within the fibromuscular wall and periductal connective tissue in the extrahepatic and large intrahepatic ducts and also in the neck of the Gall bladder...

Intracranial fibrous histiocytomas are rare; Benign Fibrous Histiocytoma (BFH) being uncommon than its malignant counterpart. BFH comprises fibroblasts and histiocytes without any nuclear pleomorphism or atypia. We present a case of a 42-year-old male who had swelling over the occipital region for the past five years, which progressively increased in size. He developed headache, dizziness, and gait disturbance over the last six months. Computed tomographic scan revealed a posterior fossa space-occupying lesion...

The differential diagnosis of proliferative breast lesions, benign usual ductal hyperplasia (UDH) versus malignant ductal carcinoma in situ (DCIS) is challenging. This involves a pathologist examining histopathologic sections of a biopsy using a light microscope, evaluating tissue structures for their architecture or size, and assessing individual cell nuclei for their morphology. Imposing diagnostic boundaries on features that otherwise exist on a continuum going from benign to atypia to malignant is a challenge...

BACKGROUND: Diagnosis of low-grade dysplasia (LGD) is important in the management of ulcerative colitis (UC), but it is often difficult to distinguish LGD from inflammatory regenerative epithelium. The unfolded protein response (UPR) is activated in inflammatory bowel disease and malignancies. We aimed to identify a UPR-related gene that is involved in the development of non-UC and UC-associated colorectal cancer (CRC), and to investigate whether the target gene is useful for the diagnosis of LGD...

The chemokine CCL3 is a chemotactic cytokine crucial for inflammatory cell recruitment in homeostatic and pathological conditions. CCL3 might stimulate cancer progression by promoting leukocyte accumulation, angiogenesis and tumour growth. The expression of CCL3 and its receptors CCR1 and CCR5 was demonstrated in oral squamous cell carcinoma (OSCC), but their role was not defined. Here, the functions of CCL3 were assessed using a model of chemically induced tongue carcinogenesis with 4-nitroquinoline-1-oxide (4NQO)...
