An eight-year-old shorthaired cat which presented with a five-month history of bouts of anorexia and vomiting, developed a large spontaneous skin tear over the left shoulder when manipulated for clinical workup. The cat had no previous history of abnormal skin fragility and clinical examination of the skin revealed a general thinning but no scarring or hyperextensibility. After one day of hospitalisation the animal was euthanased because of its poor condition and on post mortem examination a cholangiocarcinoma with distant metastasis was identified. The skin biopsy specimens obtained from different sites revealed dermal atrophic changes, characterised in electron microscopy by disorganisation in the packing of both collagen fibrils and fibres, and by collagen fibrils with an abnormally wide range of diameters and with an irregular shape in cross section. Although no specific cause of the dermal lesions was suggested, this case differed greatly from the fragile skin conditions previously described in the cat. 相似文献

Two cats with Leishmania species infections were investigated. The first had been imported from Spain with a non-healing, ulcerated nodule on a hindleg. The presence of Leishmania species was detected by histopathology and pcr on samples of skin. The lesion was unresponsive to treatment with allopurinol for three months but the cat was treated successfully by removing the lesion surgically. The second cat had lived in both Spain and Switzerland, and had a history of recurrent skin lesions on its head and neck. A diagnosis of pemphigus foliaceus was made on the basis of histopathology, but Leishmania species serology (elisa) and pcr of skin were positive, leading to a diagnosis of a Leishmania species infection combined with pemphigus foliaceus. 相似文献

Two cats with chronic eosinophilic skin disease were investigated. The clinical investigation of the skin disease in one cat was limited and inflammatory bowel disease was diagnosed post mortem. A history of weight loss and a palpably thickened bowel in the second cat suggested concurrent gastrointestinal disease. Diagnosis of inflammatory bowel disease was confirmed on biopsy. Treatment with azathioprine and methylprednisolone acetate resolved the signs of gastrointestinal disease, the pruritus and 95% of the skin lesions. The concurrence of eosinophilic papulocrustous dermatitis and eosinophilic bowel disease raises the possibility of their being linked bv a common aetiology or pathophysiology. 相似文献

A6-year-old 5.5-kg female spayed domestic short-haired cat from Tucson, AZ, presented with an ˜5-day history of progressive pelvic limb weakness. The owners had returned from a weekend away to find the cat unable to use her left pelvic limb. Approximately 2 months previously, the cat had a cough and was treated for presumptive asthma with 5 mg prednisone PO q24h. The cat had a similar cough 1 year previously and seasonal allergy was suspected. The cough resolved and prednisone treatment was discontinued. Other past pertinent history included a skin problem ˜4 years previously that was described as alopecia, erythema, and pruritus of a pelvic limb. This problem had been diagnosed as an allergy and had since resolved. The cat was housed exclusively indoors and had been adopted as a kitten from a local retail store. Viral titers (FeLV and FIV) were negative, and regular vaccinations and veterinary examinations had been completed 相似文献

We report the first case of colonic volvulus in a cat. A 12-year old spayed, female domestic shorthair cat with chronic bowel disease presentated with one-day history of lethargy and anorexia. Physical examination abnormalities included cachexia, poor perfusion, and poor skin turgor. A large, non painful, gas-filled, tubular structure, occupying the majority of the abdominal cavity was noted by palpation. Abdominal radiographs revealed a gas-filled displaced colon. Exploratory laparotomy confirmed a volvulus at the root of the colonic mysetery, along with a partial torsion of the distal colon. The majority of the colon was determined to be necrotic and was surgically resected. Due to persistent hypotension and perceived poor prognosis, the cat was euthanized. 相似文献

Abstract— The clinical, histopathological and ultrastructural features of a spayed female Siamese cat with a three-and-a-half year history of progressive cutaneous depigmentation are described. Clinically the condition was characterised by progressive leukoderma of the nose, pinna and footpad skin, and multifocal leukotrichia involving the whole body. Histopathological and ultrastructural studies confirmed the absence of melanocytes and melanin in the epidermis and hair follicles of affected areas. Immunohistochemical study revealed areas with absence of immune response to anti-vimentin antiserum, which was interpreted as a loss of dendritic cells, especially melanocytes. Diagnosis of vitiligo was based on the clinical signs and pathological features. This study adds a new case of this uncommon condition in the cat, and documents some previously non-reported features of feline vitiligo, such as the chronic progressive and generalised nature of the skin lesions, and its reversible character with partial lentiginous repigmentation on the pinna. 相似文献

An 8-year-old, male domestic shorthair cat was referred to the Matthew J. Ryan Veterinary Hospital of the University of Pennsylvania with a 3-day history of lethargy, inappetance, hyperemic skin nodules, coughing, and vomiting. Laboratory results included nonregenerative anemia, lymphopenia, thrombocytopenia, hypoalbuminemia, hyponatremia, and increased alanine aminotransferase and aspartate aminotransferase activities. Cytology of the skin nodules revealed many spindle- to crescent-shaped protozoal organisms, with morphology consistent with Toxoplasma gondii or Neospora caninum. Gross necropsy, histopathologic, immunohistochemical, and transmission electron microscopic findings confirmed a systemic protozoal infection; however, the organism exhibited characteristics of both N caninum and T gondii. Diagnosis of a T gondii-like infection was based on internal structures of the organism and positive reaction to rabbit polyclonal antibodies to T gondii. Reports of toxoplasmic dermatitis are rare in the cat and dog, and this is the first reported diagnosis of T gondii-like protozoa in skin aspirates. 相似文献

A 6-year-old spayed female domestic shorthair cat with a 3-week history of inappetence, weight loss, and hiding was examined. A palpable abdominal fluid wave, dehydration, and a small tear on the left flank were noted during initial examination. When the cat was gently restrained for blood sampling, the skin on the dorsal neck tore, leaving a 15 cm x 7 cm flap of skin. Clinicopathological abnormalities included nonregenerative anaemia, hypoalbuminaemia, increased globulin concentration, and mildly elevated aspartate aminotransferase and alkaline phosphatase activities. Abdominal fluid was viscous and had a total protein of 5.3 g dL(-1) with 316 cells microL(-1), consistent with a modified transudate. Cytology of the abdominal fluid revealed 86% nondegenerate neutrophils, 13% macrophages, and 1% small lymphocytes. Histopathological evaluation and indirect immunohistochemistry confirmed a diagnosis of feline infectious peritonitis, hepatic lipidosis and feline skin fragility syndrome. Feline skin fragility syndrome has not previously been reported in association with feline infectious peritonitis (FIP). Its inclusion as a clinical sign associated with FIP may facilitate a diagnosis. 相似文献

A 2-year-old, male neutered, domestic semi-long-haired cat was presented with a 1.5-year history of progressive, initially nonpruritic alopecia and malodorous greasy exudate affecting the distal extremities, trunk and neck but sparing the head and tail. The extensive alopecia and 'seborrhoea' were associated with severe thickening of the skin and fold formation on the dorsal head and distal extremities as well as the lateral thorax and abdomen. The hair was easily epilated, numerous milia were seen on the ventral abdomen and the caudal and lateral thighs, and mild paronychia was present. Histopathological examination of skin biopsies revealed marked cystic dilation of hair follicles and sebaceous glands with follicular hypoplasia, infundibular hyperkeratosis and variable associated inflammation. Systemic glucocorticoid therapy in combination with topical washes with chlorhexidine and miconazole resulted in a marked improvement and some hair regrowth, but the cat was subsequently lost to follow-up. The dermatosis resembles a number of conditions in other species, but it is not clear whether it is a counterpart to the hairless mutant mouse or is a unique dermatosis. 相似文献

An 8-year-old female neutered Siamese cat was presented with a recent history of incomplete excision of an apocrine gland adenocarcinoma from the palmar aspect of the right antebrachium, just proximal to the carpal joint. There was no evidence of metastasis. Wide surgical excision of the previous surgery site was performed resulting in a soft tissue defect. Partial reconstruction was achieved using digital pad transposition of the first digit (dewclaw), forming a local axial pattern flap that was transposed into the adjacent defect. The remaining defect was closed by primary apposition. The skin flap healed successfully. Some breakdown of the skin closed by primary apposition necessitated open wound management. The cosmetic and functional result of the first digital pad transposition was considered excellent, rendering it a useful means to reconstruct soft tissue defects in the carpal region. 相似文献

This case report describes a cat with metastasis of a bronchial adenocarcinoma to the abdominal skin. The cat had been treated with antibiotics and corticosteroids for several episodes of coughing when it acutely developed erythema, pustules and plaques on the abdominal skin. Diagnosis was based on cytological examination of fine-needle aspirates of cutaneous pustules, X-ray examination of the thorax and histological examination of skin biopsy samples. As the prognosis was poor, the cat was euthanased. Necropsy findings confirmed the diagnosis. Cutaneous metastases of lung carcinoma are rare in cats but have been reported in the digits with underlying bone involvement. To the authors' knowledge, this is the first report of metastasis of a feline bronchial carcinoma to the ventral skin. 相似文献

CASE HISTORY: A 6-year-old, spayed, female, domestic short-haired cat presented with severe erythroderma and scaling skin. She showed disturbed gait and mild behavioural changes. CLINICAL FINDINGS: The cat had a generalised, erythematous, scurfy dermatitis with marked, multifocal crusting and skin thickening. The skin was painful and contracted, which appeared to prevent normal freedom of movement. DIAGNOSIS: The cat was suspected to have a paraneoplastic syndrome. A mediastinal mass was located and histologically confirmed as thymoma. The cat was diagnosed with a thymoma- associated cutaneous paraneoplastic syndrome. CLINICAL RELEVANCE: This is a rare condition with few reports in the literature. The skin changes, both grossly and histologically, were considered to be different from those described in cases of paraneoplastic dermatosis associated with pancreatic neoplasia. The clinical presentation was characteristic and more cases may occur in practice than are recognised. In this case, as in previous reports, the tumour was grossly resectable, which could lead to cure of the clinical condition. 相似文献

A 13-year-old female neutered domestic longhaired cat was presented with a five-month history of progressive weight loss and bilaterally symmetrical alopecia of the ventrum, limbs and perineum. The alopecic skin had a shiny appearance and hair in the non-alopecic areas was easily epilated. Fine needle aspirate cytology of a palpable cranial abdominal mass revealed it to be of epithelial or glandular origin. A pancreatic mass was excised by left pancreatectomy during exploratory laparotomy, and histopathology and skin biopsies confirmed a diagnosis of pancreatic carcinoma with concurrent paraneoplastic alopecia. No evidence of metastases was found on liver and lymph node biopsies. At re-examination 10 weeks after surgery, the hair had fully regrown. Skin signs recurred after 18 weeks and metastatic spread of the tumour was confirmed on postmortem examination. This case confirms that paraneoplastic alopecia associated with internal malignancies is a potentially reversible process if the internal neoplasm is excised. 相似文献

Melanodermas and leukodermas are conditions involving skin pigment changes. Vitiligo, an acquired leukoderma, is an uncommon canine and feline skin disorder, with a likely autoimmune pathogenesis. It is seen more frequently in young adult purebred animals and has no apparent sex predisposition. In Brazil the first report of vitiligo was in 1986. In a 16-year period, 12 cases of vitiligo, including 11 dogs (six Rottweilers, two Doberman pinschers, one great dane, one boxer, and one mongrel dog) and one cat (Siamese), were diagnosed at our hospital. Diagnosis was based on history, physical examination, Wood´s lamp examination, and histopathologic evaluation (H&E and Masson-Fontana stains). Among the dogs, seven were male with a mean age of 34.5 months. The clinical evolution was known in five patients. Skin lesions included leukotrichia (100%) and leukoderma of the nose (100%), buccal mucosa (66.5%), lips (85.7%), and footpads (8.5%). Leukonychia was rarely seen. The only lesion in the cat was depigmented footpads.

The biomechanical properties of wounded and nonwounded skin were studied in three dogs and three cats affected with type I Ehlers-Danlos syndrome. Three nonaffected dogs and one nonaffected cat served as controls. Samples of wounded skin and adjacent normal skin were harvested at days 75, 138, 141, 144, 147, and 150. Samples were subjected to uniaxial tensile strength testing. Tensile strength, energy absorbed, and site of failure were recorded. In the dogs with Ehlers-Danlos syndrome, there was an increase in tensile strength in samples containing a scar over adjacent intact skin. In nonaffected dogs, affected cats and the nonaffected cat, the nonwounded skin samples had greater tensile strength. The energy absorbed by the skin samples during testing was highly correlated with tensile strength. 相似文献

This case report describes the history, clinical signs and diagnosis of a pruritic skin disease in three sibling cats living the same household. Clinical signs consistent with pruritus (i.e. hair pulling, hair loss, excessive grooming and face rubbing) were first noted when the cats were 6 months of age. The cats were treated for a possible ear mite and/or flea infestation; there was no response to treatment and clinical signs progressed. Although the presence of pruritus in a multiple cat household suggested an infectious or contagious aetiology, none could be identified. There was no improvement in clinical signs after a 60‐day flea control trial, three treatments of ivermectin, an 8‐week restricted diet or removal from the home for 10 days. A diagnosis of feline atopy was made on the basis of elimination of other causes of pruritus, consistent history and clinical signs, a positive intradermal skin test and response to therapy. 相似文献

A 2-year-old, female spayed, domestic shorthair cat presented to the University of Missouri-Veterinary Medical Teaching Hospital (UMC-VMTH) with an approximately 11-month history of fluid-draining pockets along her ventral thorax and axillae. The skin in these regions was erythematous, and multiple areas drained a serous to serosanguinous fluid. Fluid-filled, nodules formed along the ventrum, but these nodules disappeared as fluid drained spontaneously. Histologic assessment of skin biopsies revealed areas of vascular proliferation extending along the deep margin of the section and rare instances of invasion into the superficial dermis. These vascular channels were devoid of cells, lined by variably pleomorphic endothelial cells which had a low mitotic index. Based on the mild to moderate pleomorphism, positive staining with prospero-related homeobox gene-1 (PROX-1), and the locally aggressive nature of the tumor, a final diagnosis of lymphangiosarcoma was made. 相似文献

Two cases of feline leukaemia virus (FeLV)-associated dermatosis are described. The first cat was affected by an ulcerative dermatitis identified as a giant-cell dermatosis. The second case was a cutaneous lymphoma. In both cases, FeLV antigens and FeLV genome were demonstrated in the affected skin immunologically and with polymerase chain reaction, respectively. The first case suggests that, like other retroviruses, at least some strains of FeLV can induce syncytium formation. As FeLV antigens and genome were demonstrated in a serologically negative cat, the second case suggests that focal skin FeLV replication may occur. FeLV-associated dermatoses are rare skin conditions that may be under-diagnosed. 相似文献
