Lacrimal gland neoplasms comprise up to 18% of all orbital masses clinically and histologically. Much of our current core knowledge regarding lacrimal gland tumors stems from prior study of their more common counterparts, the salivary glands. The prognosis for each lacrimal gland tumor is contingent upon proper clinical evaluation and ultimately the histopathologic diagnosis. We describe a case of an invasive carcinoma ex-pleomorphic adenoma (Ca-ex-PA) with a cystadenocarcinoma component arising...

ABSTRACT Introduction Strains of the soleus are widely found both in amateur and professional athletes. For their accurate regional diagnoses, understanding the anatomy of the spatial relationship between muscular fibers and tendinous structures is important because their interfaces are susceptible sites to muscle strains. Therefore, this study evaluated the precise architecture of the soleus. Materials and Methods We evaluated the precise anatomical architecture of the soleus in 87 formaldehyde‐fixed...

Abstract Introduction Congenital variations of the reproductive system arise during embryonal organogenesis, although their clinical manifestations present later in adolescence or during reproductive years due to functional disorders such as abnormal menstruation, sexual dysfunction, infertility, and pregnancy loss. Surgical treatment of congenital variations is performed according to variant anatomy and functional disorders. However, many congenital anatomic variations are difficult to categorize...

Abstract Background Although fine needle aspiration cytology (FNAC) is highly accurate for detecting breast malignancies, concerns remain among cytopathologists about false‐positive and false‐negative diagnoses. Cell block (CB) preparations have been advocated by some cytopathologists as one of the methods to improve and consolidate the diagnostic accuracy of FNAC. The aim of this study was to determine the diagnostic utility of CB in FNAC of palpable breast lesions among female patients. ...

Abstract The Paris system for reporting urinary cytopathology (TPS) was created to address inherent weaknesses inherent in the practice of urinary cytopathology. While urothelial cytology has always performed well at finding high grade, genetically unstable urothelial carcinoma, it performs poorly when it comes to detecting low‐grade urothelial neoplasia. TPS intends to improve the utility of urothelial cytology by focusing on what is important, high‐grade urothelial carcinoma. This article is a...

In search of atrial volume receptors, we performed immunohistochemical characterisation of the subendocardial nerve plexus of the rat right atrium. Rats possess a bicuspid Eustachian valve which is richly innervated. Fine adluminal end‐nets expressed vesicular markers, CGRP and tyrosine hydroxylase. Immunohistochemistry did not label flower‐spray endings but these were identified with methylene blue. The observed plexuses could represent sympathetic post‐ganglionic and/or sensory afferents. Abstract...
