A total of 243 neoplasms were recorded in a survey of all the feline neoplasms which are reported in the registration files of the Veterinary Research Institute, Onderstepoort, Republic of South Africa, covering a 40-year period from 1935 to 1974. The tissues most commonly neoplastic were the skin, followed by the lymphoid tissue, the digestive tract and the genital system, which together accou...

  Primary non-Hodgkin lymphoma of the larynx is rare, accounting for less than 1% of all laryngeal neoplasms. Fewer than 100 cases have been reported in the literatureand to our knowledge this may be the first reported case of laryngeal non Hodgkin lymphoma presented with hoarseness, aortic aneurysm, hepatitis B and skin rashes.

Background:Non-Melanoma Skin Cancer (NMSC), the most prevalent types being Squamous Cell Carcinoma (SCC) and Basal Cell Carcinoma (BCC), is the most common type of malignancy in human beings. These neoplasms are more frequent in the elderly and fair skinned people and mainly occur on sun-exposed sites of the body. Ultraviolet B (UVB) has a wel...

Nowadays, neoplasms have become the common surgical affections encountered in pet population, especially dogs. Skin are most neoplasm observed dogs, followed by mammary neoplasms. Most of may exhibit metastatic and paraneoplastic changes distant sites other than primary tumor sites, mainly thorax. The present study investigated evaluation radiographically evident cardio-pulmonary, thorax twenty...

Background: Cutaneous lymphomas are monoclonal neoplastic proliferations of immune cells most frequently T or B cells that infiltrates skin. Development of new diagnostic methods, particularly those for immunophenotyping, have substantially changed classification of these neoplasms. These reasons prompted us to perform this study. Objective: To re-classify cutaneous lymphomas and pseudoly...

Skin tests to various common antigens, dinitrochlorobenzene, and 5-fluorouracil (5-FU) were performed on patients being treated for cutaneous neoplasms with topical 5-FU cream. Eleven of 15 patients tested both before and after therapy converted from skin test negative to positive with respect to 5-FU. This conversion correlated with positive dinitrochlorobenzene skin tests and therapeutic cure...

Skin adnexal neoplasms comprise a wide spectrum of benign and malignant tumours that exhibit morphological differentiation towards one or more types of adnexal structures found in normal skin. Most adnexal neoplasms are relatively uncommonly encountered in routine practice, and pathologists can recognise a limited number of frequently encountered tumours. In this review, the first of two, the n...

Melanomas usually present as oval lesions in which the borders may be irregular. Other morphological features of melanoma include clinical asymmetry, variable color, diameter greater than 6 mm and evolving lesions. Two males whose melanoma in situ presented as linear skin lesions are described and cutaneous malignancies that may appear linear in morphology are summarized in this report. A medic...

Malignant neoplasms diagnosed histologically in the state of Sabah during the period November 1983 to October 1988 were analysed to determine the distribution of malignant neoplasms according to site, age, sex and major ethnic groups. The five commonest malignant neoplasms in males were carcinomas of the nasopharynx, stomach, skin, lung and liver. In females the five commonest malignant neoplas...

Sox9 is a master regulatory gene involved in developmental processes, stem cells maintenance and tumorigenesis. This gene is expressed in healthy skin but even in several skin neoplasms, where its expression patterns often resembles those of the developing hair follicle. In this study, samples from eleven different types of canine skin neoplasms (squamous papilloma, squamous cell carcinoma, inf...
