IMAGING DIAGNOSIS—SUBLUMBAR PSEUDOMYCETOMA IN A PERSIAN CAT

Successful treatment of an intra-pelvic fungal pseudomycetoma causing constipation and hypercalcaemia in a Persian cat

This case report describes the successful treatment of a Persian cat diagnosed with intra-abdominal fungal pseudomycetoma causing hypercalcaemia and constipation due to an extra-luminal mechanical obstruction of the colon. Treatment included surgical excision, supportive care and itraconazole for 6 months.

Disseminated dermatophytic pseudomycetoma caused by Microsporum species

BACKGROUND

Dermatophyte infection is almost exclusively a superficial cutaneous mycosis usually confined to the stratum corneum of nails and hairs of normal hosts. Deep cutaneous and subcutaneous infections due to dermatophytes are exceedingly rare and usually limited to immunosuppressed individuals. These infections remain chronic and persist in spite of treatment.

MATERIALS AND METHODS

We report two clinical cases of disseminated dermatophytic pseudomycetoma caused by Microsporum gypseum and Microsporum canis in immunosuppressed patients.

RESULTS

Patient 1, in 2008, showed improvement with fluconazole, cephalothin, and terbinafine treatment for Microsporum gypseum. After suspension of the treatment, new lesions appeared and culture from material was positive. In 2009, she presented confluent papules and nodules forming plaques on her face and neck with the isolation of Microsporum canis. Clinical response to this treatment was poor. Patient 2 was affected by both tinea corporis due to Trichophyton rubrum and dermatophytic pseudomycetoma caused by Microsporum canis. The response to treatment was successful with oral itraconazole and local surgical excision.

CONCLUSIONS

It is important to recognize these atypical presentations of dermatophytic infections in immunosuppressed patients, which may warrant a more aggressive treatment in order to achieve resolution.

Mechanisms, causes, investigation and management of vomiting disorders in cats: a literature review

Vomiting is a common presenting complaint in feline practice. This article differs from previous reviews in that it is an evidence-based review of the mechanisms, causes, investigation and management of vomiting in the domestic cat. Published evidence was reviewed, and then used to make recommendations for clinical assessment, diagnosis, antiemetic drug treatment, dietary management and monitoring of cats presenting with vomiting. The strength of the evidence on which recommendations are made (and areas where evidence is lacking for cats) has been highlighted throughout.
