“ Our deepest fear is not that we are inadequate, our deepest fear is that we are powerful beyond measure…” - Marianne Williamson
An acute or chronic inflammatory disease of the external ear canal Clinical signs: › Head rubbing or shaking › Ear scratching › Head tilt – with the affected ear tilted down › Malodorous otic discharge (brown, greenish- yellow) › Lichenification, hyperpigmentation, crusts, erythema and excoriations may be present › Aural hematoma
NOTE THE EXCESS BROWN EXUDATE AURAL HEMATOMA ERYTHEMA, HYPERPIGMENTATION, LICHENIFICATION
PREDISPOSING FACTORS: › Conformation Heavy, pendulous ears Stenotic ear canals Ear hair › Excessive moisture Frequent bathing or swimming › Hypersensitivities Food allergy, atopy
DIAGNOSIS: › Otoscopic exam › Clinical signs › Cytology, ear smear Yeast, bacteria, cerumen, skin cells
MALASSEZZIA OTITIS Malassezzia resemble footprints, bowling pins, or snowmen
BACTERIAL OTITIS ROD-SHAPED BACTERIA AND A SKIN CELL
TREATMENT › Always treat the underlying condition if present › Topical meds instilled daily Antibacterial, antifungal, or combination products often with steroids (otomax, tresaderm, baytril otic) Cleaning ears during treatment › Surgical intervention may be required Aural hematoma Chronic conditions (Total Ear Canal Ablation)
The anal sacs are located between the muscle layers of the anus at the 4 and 8 o’clock positions. Each sac connects to the surface through a narrow duct. Sebaceous glands produce a foul-smelling oily, brown fluid. The sacs are naturally expressed during defecation, but can sometimes overfill.
IMPACTION › When the sacs overfill, the water can be reabsorbed, and the material dries out. Sacs become a source of discomfort for the dog and are difficult to express at this time. › Impaction can lead to abscessation and rupture. Clinical signs include: scooting rear end across the floor, painful defecation, tail chasing, perianal erythema, and/or swelling
DIAGNOSIS › Palpation (rectally or externally) › Clinical signs TREATMENT › Express contents › Flush sac › Instill antibiotic ointment › Oral antibiotics, anti-inflammatories › Surgery?
WEARING GLOVES, GENTLY MILK THE GLANDS IN AN UPWARD MOTION TO EXPRESS.
Tumors are a new growth of tissue characterized by progressive, uncontrolled proliferation of cells. Benign vs. Malignant Localized vs. Invasive Adenoma/Carcinoma vs. Sarcomas
HISTIOCYTOMA: small, button-like tumors that are usually pink, hairless, and raised. They are rapidly growing Common locations include the pinnae, head, and legs
HISTIOCYTOMA › Occurs almost exclusively in young dogs <4yrs old DIAGNOSIS › Appearance › biopsy TREATMENT › These tumors may spontaneously regress, but surgical excision is the treatment of choice ROUND CELL TUMOR
LIPOMA: tumor of the subcutaneous adipocytes (fat cells) that are typically freely movable and well-circumscribed › Common in older, female, obese dogs DIAGNOSIS: › Biopsy › Fine needle aspirate
LIPOMA › TREATMENT: Surgical excision Benign neglect lipocytes
PAPILLOMAS: wart-like growths that develop as smooth, white/pink/pigmented, elevated lesions in the oral cavity (oral papillomatosis) or on the skin (cutaneous papillomas) › These growths are caused by a papillomavirus
PAPILLOMAS › DIAGNOSIS: Appearance Biopsy › TREATMENT Usually spontaneous regression Autogenous vaccine
SEBACEOUS GLAND CYSTS: Slow growing, encapuslated, round, and exude a gray, cheeselike material. Caused by degenerative changes in the glandular area surrounding the follicle. › Common in cocker spaniels DIAGNOSIS Contents of the cyst histology TREATMENT › Surgical removal of entire encapsulated cyst
SEBACEOUS CYSTS
FELINE VACCINE-INDUCED FIBROSARCOMAS: rapidly developing, highly invasive, malignant tumors that occur at the site of vaccination ~4-6 weeks later. › VACCINES MOST COMMONLY IMPLICATED ARE THOSE WITH ADJUVANTS (substance that enhances the immune response by increasing the stability of a vaccine in the body) SUCH AS FeLV AND RABIES
VACCINE- ASSOCIATED SARCOMAS › DIAGNOSIS: Biopsy of fine needle aspirate Physical exam findings Swelling in area of recent vaccination Rapidly growing firm elongated mass
VACCINE-ASSOCIATED SARCOMAS › TREATMENT Radical surgical excision which may involve limb amputation is the treatment of choice › CLIENT INFORMATION Poor prognosis if not detected early and treated aggressively Inflammatory lumps may do develop after vaccines but usually disappear within 1-2 weeks
FELINE VACCINE-ASSOCIATED SARCOMAS
MAST CELL TUMORS: firm nodules on the skin that may be ulcerated or edematous. Mast cells contain histamine and heparin
FINE NEEDLE ASPIRATE OF MAST CELL TUMOR; NOTE THE NUMEROUS GRANULES
IN CATS, MAST CELL TUMORS ARE USUALLY BENIGN AND MAY SPONTANEOUSLY REGRESS
MAST CELL TUMOR › TREATMENT Chemotherapy Radiation therapy BENADRYL H2 blockers to treat gastric ulceration and irritation › PROGNOSIS Depends on biopsy “grading” results
MELANOMA (Benign or Malignant) › BENIGN: small, slow growing, hairless, pigmented › MALIGNANT: large, dome-shaped sessile +/- pigmentation Ex: Tumors of the oral cavity and digits Poor prognosis Metastasize readily Recurrence after surgery is common
TREATMENT INVOLVES SURGICAL REMOVAL AND POSSIBLY TREATMENT WITH THE VACCINE
