Nerve sheath myxoma defined by Harkin and Reed is an uncommon benign neoplasm with nerve sheath like features. It has several cytological and histological differential diagnoses. One such lesion is neurothekeoma, which can be differentiated using immunohistochemistry. In most of the previous reports nerve sheath myxoma and neurothekeoma were considered synonymous and were often confused for one...

dear editor-in-chief   lesional histopathological features in pityriasis rosea (pr) are non-specific (1).  our aim here is to investigate whether a histopathological take-off sign (tos) is associated with pr.

Cyto-nuclear incompatibility, a specific form of Dobzhansky-Muller incompatibility caused by incompatible alleles between mitochondrial and nuclear genomes, has been suggested to play a critical role during speciation. Several features of the mitochondrial genome (mtDNA), including high mutation rate, dynamic genomic structure, and uniparental inheritance, make mtDNA more likely to accumulate m...

Introduction: Fine Needle Aspiration Cytology (FNAC) is a simple, safe, very low-cost and rapid procedure for diagnostic purpose which makes surgical intervention exploratory laparotomy unnecessary. The introduction of modern imaging techniques, mainly ultrasonography (USG) Computerized Tomography (CT), has enabled the detection location lesions in sites such as liver, are not easily accessible...

UNLABELLED Cutaneous mast cell tumours (MCTs) are the most common skin tumours in dogs. Due to the prevalence of canine MCTs and the variable biologic behavior of this disease, accurate prognostication and a thorough understanding of MCT biology are critical for the treatment of this disease. A cytologic diagnosis of mast cell tumor with evidence of prior hemorrhage was made, and the masses wer...
