Abstract:

Abstract Context.—The importance of frozen-section diagnoses in the practice of pathology cannot be overemphasized. In some cases, the use of a mucin stain can greatly aid in the diagnosis. Since few methods for mucin staining have been described that can be used in the frozen-section setting, we developed one such staining procedure for mucin. Objective.—To develop a rapid mucicarmine staining technique to be used on frozen sections that does not significantly delay overall turnaround time. Design.—A standard mucicarmine staining technique was modified by using a concentrated mucicarmine stai

Ten cases of cryptococcosis due to unusual microscopic forms of Cryptococcus sp. observed over a twenty-eight year period (1981-2009) are presented. The most important clinicopathological and laboratory data are tabulated. The uncommon forms of cryptococcal cells given are: structures resembling germ tube (one case), chains of budding yeasts (one case), pseudohyphae (two cases) and nonencapsulated yeast-like organisms (eight cases). The diagnosis was based on the histopathological findings. The causative organism was isolated and identified in seven cases; five were due to C. neoformans, and t

Abstract:

Abstract We present a unique carcinoma of the pancreas with predominantly clear cell morphology (&gt;95% clear cells). Mucicarmine stain revealed abundant intraluminal and intracytoplasmic mucin. Immunohistochemically, the cells were positive for the epithelial markers cytokeratin 7 and CAM 5.2, and were focally positive for cytokeratin 20. These cells also expressed monoclonal carcinoembryonic antigen. Stains for the neuroendocrine markers synaptophysin and chromogranin were negative, as were stains for vimentin, p53, HMB-45, and CD10. An additional outstanding feature was the presence of

Abstract:

Intracytoplasmic lumina occur mainly in infiltrating lobular carcinoma. Their identification in large number provides additional support for the breast origin of a metastatic tumor. Although intracytoplasmic lumuina were originally characterized with the electron microscope, they can be identified by light microscopy. Recently their usefulness in histopathologic diagnosis has received attention. However, their role in cell physiology or pathology remains unknown. It is not known whether they communicate with the exterior of the cell. This information might suggest a possible function. In attem

He was admitted because of pain in the anus and left hip. He underwent abdominal computed tomography that revealed a newly developed left perirectal mass with gluteus maximus invasion measuring up to 8 cm, and therefore, an abdominoperineal resection was performed.

Abstract Context.—Squamous carcinoma in a major salivary gland has several possible sources: (1) high-grade mucoepidermoid carcinoma, (2) metastasis or direct invasion from a primary skin carcinoma, (3) metastasis from a distant primary carcinoma, or (4) a primary malignant neoplasm. The latter is conventionally regarded as a diagnosis of exclusion after a history of squamous carcinoma elsewhere has been obtained or there is a positive mucin stain.

Abstract:

Mucoepidermoid carcinoma (MEC) accounts for only 5% of all salivary gland tumors and is most often seen in the parotid glands. MEC occurrence in the larynx is, however, rare. The incidence of primary squamous cell carcinoma (SCC) of salivary glands is also scarce and comprises only about 1.6% of all salivary gland malignancies. Hereby, we share our experience in managing two patients with rare and opposite variants of malignancy which were diagnosed at the same time; MEC of the larynx and SCC of the parotid. In MEC tumors, the presence of the intermediate and mucous cells with positivity in mu

Human immunodeficiency virus (HIV)-infected patients are at an increased risk for developing opportunistic infections, reactive conditions and neoplasms. As a result, a broad range of conditions are frequently included in the differential diagnosis of HIV-related lesions. The clinical history of HIV infection may, however, be misleading in some cases. Illustrative cases are presented in which knowledge of a patient's HIV status proved to be misleading and increased the degree of complexity of the cytologic evaluation.

This premalignant lesion is often found in proximity to HG-SIL, AIS and invasive carcinomas. SMILE is also a precursor for Invasive Stratified Mucinous Carcinoma. As was first described in the original article, SMILE lesions are considered derived from the reserve cells at the transformation zone where HPV infections lead to varied phenotypes. Methods Two
