Cutaneous blastomycosis and dermatophytic pseudomycetoma in a Persian cat from Bangkok, Thailand

Abstract

This is a case report of concurrent of blastomycosis and pseudomycetoma in a 3 year-old Persian cat from Bangkok, Thailand. Histopathology from antemortem and postmortem samples revealed blastomycosis and dermatophyte pseudomycetoma. The PCR analysis of the formalin-embedded tissue of antemortem sample confirmed that blastomycosis was caused by Blastomyces dermatitidis. Dermatophyte infection was caused by Microsporum canis. According to the author's knowledge, this is the first case of Blastomyces dermatitidis and dermatophyte pseudomycetoma in South-East Asia.

Epidemiological aspects of travel-related systemic endemic mycoses: a GeoSentinel analysis, 1997–2017

“…However, recently, cutaneous blastomycosis was detected in a Persian cat from Thailand (confirmed by histopathology and PCR from tissue samples). 32 We report here the first published travel-related blastomycosis infection acquired in Thailand. Nevertheless, the risk of blastomycosis for travellers visiting Asia is likely low.…”

Pathology of cutaneous blastomycosis in a cat

“…Pathological characteristic of this case is scattered pyogranulomatus nodules in affected tissue, particularly in lungs and skin with spherical or rounded yeats, aseptate pseudohyphae, admixed with variable infiltration of inflammatory cells such as lymphocytes, plasma cells, neutrophils and macrophages (Gross et al 2005;Jankovsky and Donnell 2014;Duangkaew et al 2017). To the author's knowledge there has been no reported case of feline cutaneous blastomycosis in Indonesia.…”

“…One of the disease in both human and animals is mycoses that caused by numerous species of pathogenic yeasts and molds (Gross et al 2005). Blastomycosis due to infection of Blastomyces spp yeasts is systemic and local mycosis that disseminate particularly to the skin; Blastomyces dermatitidis is a common causative agent (Jankovsky and Donnell 2014;Duangkaew et al 2017). Blastomycosis is endemic in American and Asian Continents and many cases have been reported in Middle East, South Asia, and Southeast Asia (Duangkaew et al 2017).…”
