This paper comes with a purpose to help the clinician as how to arrive at a logical differential diagnosis when an upper lip mass is encountered in day-to-day practice. The labial mucosa is commonly traumatized. One must be aware of the type of structures contained in the mucosa of the area of a lesion as well as the patients habits since they may relate to a lesion presented for diagnosis.

Benign vs Malignant Tumors

Objectives: To study the histopathological features of neoplastic and non neoplastic lesions of breast. To correlate the pathological findings with clinical parameters. Design and methods: We have studied total cases of breast lesions over a period of two years in our institute.

The specimens were received in histopathology section of our department. Detailed gross examination of specimens was done followed by fixation, thorough sampling, and tissue processing. The different lesions were studied by histopathological examination and analysed.

Neoplastic lesions were classified according to the WHO classification Results: Out of the cases, cases had neoplastic lesions and 32 cases had non-neoplastic lesions, and one case had coexistent neoplastic and nonneoplastic lesions. Two cases had dual neoplastic lesions. Out of the total cases with neoplastic lesions, 76 cases had benign breast tumors, 53 cases had malignant breast tumors, and 2 cases had precursor lesions. Fibroadenoma was the most common benign tumour with 60 cases.

Invasive carcinoma no special type was the most common malignant tumour with 43 cases. Special subtypes of invasive carcinoma found in our study were metaplastic carcinoma 3 cases and mucinous carcinoma 1 case. The most common nonneoplastic lesion was mastitis with 12 cases, followed by duct ectasia and fibrocystic change.

There were 4 cases of gynaecomastia. All the tumors involved upper outer quadrant most frequently. The benign tumors were most frequent in second, third and fourth decades, malignant tumours were seen beyond 4th decade.

Histopathological study of breast lesions

There has been remarkable progress in the field of surgical pathology; however, histomorphology has remained the most important and essential tool of the surgical pathologist in everyday practice till now. It is surprising that the hematoxylin—eosin H and E stain, introduced more than a century ago, has still remained the gold standard stain for histological examination and diagnosis of human diseases. Besides different findings or clues observed in histopathology sections like inclusions, granules, grooving, globules, halo, or clearing, which would enable the pathologist to provide a precise and accurate diagnosis; observation of clear cells is one of the important findings and clue for reporting. It may also sometimes lead to difficulties and delays in establishing the diagnosis. It can be focal or extensive and primary or rarely it may be secondary. Clear cell changes may be observed in many non-neoplastic, benign, or malignant tumors of diverse origin.

A tumor also called neoplasm is an abnormal mass of cells in the body. It is caused by cells dividing more than normal or not dying when they should. Tumors can be classified as benign or malignant. Benign tumors are those that stay in their primary location without invading other sites of the body. They do not spread to local structures or to distant parts of the body. Benign tumors tend to grow slowly and have distinct borders. Benign tumors are not usually problematic.

T HE relationship between benign and malignant thyroid tumors has been for many years a subject for interesting discussion. The interest has been due largely to a common opinion that many, perhaps most, thyroid carcinomas arise from a benign thyroid tumor which pre-existed for a variable length of time before transforming itself into a cancer. The evidence for such an opinion has been mostly clinical; the pathologic demonstration of the actual transformation or transition of a benign thyroid tumor to a malignant one has not always been so clear or as acceptable.

Overview and Classification of Conjunctival and Corneal Tumors

The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger is removed. ICD classifies neoplasms into four main groups: benign neoplasms , in situ neoplasms , malignant neoplasms , and neoplasms of uncertain or unknown behavior. Prior to the abnormal growth of tissue, as neoplasia, cells often undergo an abnormal pattern of growth, such as metaplasia or dysplasia. A neoplasm can be benign , potentially malignant, or malignant cancer. Neoplastic tumors are often heterogeneous and contain more than one type of cell, but their initiation and continued growth is usually dependent on a single population of neoplastic cells. These cells are presumed to be clonal — that is, they are derived from the same cell, [9] and all carry the same genetic or epigenetic anomaly — evident of clonality. For lymphoid neoplasms, e.

When you hear the word tumor, you likely think of cancer. Even so, they can cause serious problems when they grow near vital organs, press on a nerve, or restrict blood flow. Benign tumors usually respond well to treatment. Adenomas, or polyps , develop in glandlike cells in epithelial tissue, a thin layer of tissue covering glands, organs, and other structures. Treatment depends on location and size.

T HE relationship between benign and malignant thyroid tumors has been for many years a subject for interesting discussion. The interest has been due largely to a common opinion that many, perhaps most, thyroid carcinomas arise from a benign thyroid tumor which pre-existed for a variable length of time before transforming itself into a cancer. The evidence for such an opinion has been mostly clinical; the pathologic demonstration of the actual transformation or transition of a benign thyroid tumor to a malignant one has not always been so clear or as acceptable. It is known that in most organs of the body benign tumors have malignant counterparts as far as histologic structure is concerned; therefore, in order to further the pathologic understanding and evaluation of thyroid tumors in general, a comparison and contrast of the histologic growth patterns of benign and malignant thyroid neoplasms seemed indicated. Such a study was carried out to determine, in addition to general information regarding thyroid tumors: 1 whether comparable histologic patterns do occur in benign and malignant thyroid neoplasms; 2 if comparable patterns occur, the relative frequency of the respective patterns in benign and malignant states; 3 the relationship, if any, of the various growth patterns to age and sex; and 4 the value of current histologic classifications of thyroid tumors.

Tumors affecting the conjunctiva and cornea include benign and malignant neoplasms arising from the conjunctival epithelium, conjunctival stroma, and structures within the stroma including the blood vessels, nerves, fat, and lymphoid tissue. Corneal tumors can arise specifically from the corneal epithelium, and rarely does the stroma promote a tumor. Most corneal tumors are secondary to extension from an adjacent conjunctival tumor. Corneal tumors can arise specifically from the corneal epithelium and rarely does the stroma promote a tumor. The first step in the management of a conjunctival tumor is to take a detailed history regarding the onset, previous precursors, rate of growth, and presence of symptoms such as pain or irritation. The second step is proper evaluation by external examination and slit lamp biomicroscopy.
