Preface 
 
Histopathology, the discipline that studies the lesions that produce the pathological 
states in living organisms, is in expansion. It applies basic knowledge obtained from 
biological  and  anatomic  science  to  make  diagnosis,  determine  the  severity  and 
progress of a condition and to evaluate the possible response to certain therapies. 
Thus,  it  is  not  surprising  that  this  discipline  constantly  expands  with  progress 
produced  in  biology.  In  addition,  novel  technologies  that  have  been  recently 
incorporated and the adoption of the histopathological methods by different areas 
contribute to enlarge the fields that may apply the histopathological methodology.  
A major goal of the book is to bring together reputable researchers from different 
countries in order to provide a comprehensive coverage of advanced and modern 
topics in pathology. 
The papers selected for this book comprise a cross-section of topics that reflect the 
variety of perspectives that histopathology contemplates. This book presents selected 
reviews of areas that cover topics that are considered relevant, and introduce novel 
concepts and descriptions of new entities. 
The 13 chapters that have been selected for this book adequately review representative 
and diverse fields that are considered of special interest for their innovation or for 
their relevance in diagnostic pathology. 
The 1st chapter, “Human Papillomavirus Detection In Head And Neck Squamous 
Cell Carcinomas And Its Clinical Implications”, deal with one of the hot topics of 
recent pathology. It has been shown that the presence of Human Papillomavirus 
(HPV) is a necessary event for development of cervical carcinoma. Although HPV has 
been detected in other genital tumours and in head and neck tumours, its presence is 
not constant, and it is controversial if detection of the virus may implicate it as an 
etiopathogenic  factor.  The  chapter  analyzes  several  methods  for  human 
papillomavirus detection, analyze the implications that this detection may represent, 
and review the biological and clinical aspects of human papillomavirus related with 
squamous cell carcinoma of the head and neck.
X  Preface 
 
The 2nd chapter, “Shadow Keyplayers of the Uterine Cervix Lesions Progression and 
Metastasis”, is focused on early steps of angiogenesis and lymphangiogenesis in 
preneoplastic and neoplastic lesions of the uterine cervix.  
Cervical  neoplasia  remains  one  of  the  most  controversial  issues  for  clinicians, 
pathologists,  and  researchers.  Screening  programs  has  been  very  important  for 
reducing the incidence of invasive neoplastic lesions because these programs detect 
early,  preneoplastic  lesions  that  can  bee  properly  treated.  However,  the  rate  of 
precursor lesions remains intact, and the study of some of the pathogenetic events that 
occur in these early stages of neoplasia are afforded in this chapter. Angiogenesis and 
lymphangiogenesis are accepted as important factors favouring tumor growth and 
metastases. But, questions about (i) startpoint of angiogenesis and lymphangiogenesis 
in cervical lesions, (ii) proliferative and/or activated status of cervical neovessels or (iii) 
the origin of lymph vessels and prognostic impact of lymphangiogenesis in precursor 
lesions of the uterine cervix still remain without a precise response. This interesting 
chapter afforded these important issues.  
The 3rd chapter, “Surgical and Clinical Pathology of Breast Diseases”, describes in a 
precise manner pathological aspects of the most common breast diseases. In addition, 
some indications regarding the proper management that should be considered for the 
correct diagnosis of these lesions are included in the text. Selected illustrations that are 
present in the chapter emphasize the importance of histopathology in the diagnosis of 
breast lesions.     
The  4th  chapter,  “On  the  Bone  Tumours:  Overview,  Classification,  Incidence, 
Histopathological Issues, Behavior and Review Using Literature Data”, reviews 
several aspects of bone tumours. Although metastatic bone tumours are frequent, 
primary bone tumours account for 0.2% of all malignant neoplasms in humans. The 
authors review their own case serie according to the World Health Organization 
classification. The most important thing in dealing with a bone tumour is a correct and 
full diagnosis as is shown in this chapter. 
The 5th chapter, “Nocardiosis: Clinical and Pathological Aspects”, Nocardiosis is an 
opportunistic, localized or disseminated granulomatous infection caused by an aerobic 
actinomycete.  The  chapter  represents  a  comprehensive  review  of  this  infection. 
Although nocardiosis infection most commonly occurs through the respiratory tract, 
manifestations  of  disease  range  from  cutaneous  infection  caused  by  traumatic 
inoculation of the organism in a normal host, to severe hematogenous spread, or to 
pulmonary or central nervous system disease in an immunocompromised host. The 
chapter review several aspects of epidemiology, microbiology, pathogenesis, clinical 
features, and treatment related to nocardiosis. 
The 6th chapter, “Cytopathology of Canine Mammary Gland Affections”, represent a 
structured description of a novel, useful, and affordable technique used for diagnosis 
of  tumours.  The  chapter  review  fine  needle  aspiration  cytology  as  a  quick, 
inexpensive, and easily repeatable diagnostic technique for diagnosis of mammary
Preface  XI 
 
gland affections in dogs. All technical aspects of the fine needle aspiration cytology 
technique are precisely described. The diagnostic value of cytology in mammary gland 
affections is emphasized showing that cytological interpretation is quiet helpful in 
rapid screening of the mammary gland affections, and in differentiating benign and 
malignant neoplastic lesions. The citological findings and the diagnostic interpretation 
of the fine needle aspirates complete this chapter, that is supported with very helpful 
illustrations. 
The  7th  chapter,  “Ossifying  Fibromas  of  the  Craniofacial  Skeleton”,  afford  a 
controversial issue because the accurate nature and classification of ossifying fibromas 
has undergone considerable debate among pathologists. This debate has produced a 
confusing evolution of competing nomenclatures. Authors of this chapter achieve to 
clarify this issue, and show that the definitive diagnosis can rarely be rendered on the 
basis of histopathologic features alone. Definitive diagnosis is usually dependent upon 
assessment of microscopic, clinical and imaging features together. Described subtypes 
vary with regard to behavior and propensity for recurrence after surgical excision. The 
chapter discusses the clinical, microscopic, radiological and therapeutic aspects of 
ossifying fibromas. 
The 8th chapter, “Morphology of the Intestinal Barrier in Different Physiological and 
Pathological Conditions”, discuss the factors responsible for gut barrier dysfunction 
and  possible  morphological  changes  of  the  barrier  during  several  conditions. 
Discussion is made in an attempt to provide a generalized idea of morphological 
changes during several conditions. Many harmful factors such malnutrition, chronic 
psychological stress, infections, or drugs are responsible for the damage of the gut 
barrier. Understanding the morphological changes of the gut barrier during various 
illnesses  would  enhance  the  knowledge  of  different  preventive  or  therapeutic 
modulating agents of the gut barrier.  
The 9th chapter, “Histological Change of Aquatic Animals by Parasitic Infection”, 
focuses on the category and diversity of the parasites that infect the aquatic animals. 
Histological methods are becoming quiet common in diagnostic methodology in 
aquatic animals. The author has collected more than 120 species of parasites from wild 
and cultured fish from freshwater and marine fish. The chapter discusses the port of 
entry and the site of localization into the host system. The degree of pathogenicity in 
relation to the histological observations detected is also analyzed.  
The 10th chapter, “Toxicology of the Bioinsecticides used in Agricultural Food 
Production “, introduces a relatively new problem, that is the consequence of increases 
in the quantity of chemical pesticides required to control the losses in production 
caused by insect. The authors address the toxicological aspects of microbial and 
botanical  biopesticides  that  act  by  ingestion  with  emphasis  on  histopathological 
analysis of tissues and cells in the alimentary channel of the Lepidoptera, as well as the 
specificity of the Bacillus thuringiensis bacteria, aqueous extracts and essential oil of 
medicinal and forest. For the application of plant and microbial toxins as biopesticides
