Blastomycosis
Blastomycosis is an infection caused by the fungal organism Blastomyces dermatitidis. The disease usually results in respiratory infection; however, the organism can cause disease in many body tissues including the eyes, skin, reproductive tract, and bones. Blastomycosis is a serious disease that can be fatal. Blastomyces dermatidis is found in the environment predominantly in the Missouri, Ohio, Tennessee, […]

Cryptococcus
Cryptococcosis is a common fungal infection in cats which causes sneezing, mucopurulent nasal discharge and lymphadenopathy. Cryptococcosis is caused by a Gram-positive yeast that has worldwide distribution with an increased incidence in temperate regions such as southern California and Australia. It affects numerous mammalian species, including dogs, cats, and humans. Cryptococcus neoformans is the species that primarily causes this disease in […]

Ethics
It is a self-evident truth that wherever there is consciousness, there is some degree of suffering, whether that pain be physical or psychological[1]. Consequently, the study of ethics is an examination of the rights and welfare of all living things which possess consciousness. Pertinent to this arena of feline medicine, ethics deals with an ethical code that is the […]

Squamous cell carcinoma
Squamous cell carcinomas (SCCs), are a relatively common cancer of cats, affecting the ears, nose and eyelids of cats. It occurs more frequently in white cats, but is seen in other bi-color and tortoiseshell cats, especially when there is little or no pigment in these areas. Actinic keratosis, a prequel to this form of epidermal carcinoma, are […]

Melanoma
Melanoma are a rare and highly metastatic skin disease of cats. In cats, melanoma account for less than 1% of all feline oral neoplasms and approximately 0.5% of feline skin tumors[1]. The ocular and cutaneous forms are generally more common than melanoma of the oral cavity[2]. The most common cutaneous sites are eyes, mouth, dorsal head region, […]

Mast cell tumour
Mast cell tumours are a rare skin disease of cats, but the second most common feline skin tumours (following basal cell tumours). Mastocytaemia in cats appears exclusively associated with mast cell tumours[1]. There are two forms of mast cell tumours; a mastocytic form that histologically resembles normal mast cells and a histiocytic cutaneous form that histologically resembles histiocytic mast […]

Mammary tumours
Feline mammary carcinomas are one of the most common neoplasms affecting middle-aged and older female cats of all breeds. Because most feline mammary tumours are malignant, early detection and aggressive therapy have a significant influence on survival time[2]. The percentage of malignant mammary tumours is higher in the cat (86%) than in the dog (42%)[3], […]

Fibrosarcoma
Sarcomas and fibrosarcomas are rare skin diseases of cats. Sarcomas are neoplasms of mesenchymal (stem cell) origin, and are different to neurofibrosarcoma of nerve tissue origin. Fibrosarcomas are malignant mesenchymal tumours arising from fibroblasts. They can occur at any anatomical location and are common in cats, comprising 24 to 33% of tumours of skin and subcutis. Malignant fibrous histiocytoma […]

Fibropapilloma
Fibropapillom are a rare but benign neoplastic skin disease of cats. From the first descriptions of feline cutaneous fibropapillomas in the 1990s, the morphologic similarity to equine sarcoids was immediately recognized. Since equine sarcoids have a strong association with papillomaviruses, a similar association was investigated in cats. Early investigations proved negative; however, a recent report provides strong […]
