Implantation Mycoses and Invasive Fungal Infections with Cutaneous Involvement in Tropical Taiwan: An 11-Year...

The rising incidence of implantation mycoses and invasive fungal infections prompts the need for studies describing the latest trends of these diseases; however, the literature remains scarce from tropical Asia in recent years. We shared our 11-year clinical experience at a tertiary center in Southern Taiwan to improve physicians' understanding of the diseases, which could help them assume appropriate management strategies.

Forty cases of pathology-proven cases of implantation mycoses and invasive fungal infections with cutaneous involvement were retrospectively reviewed. The epidemiology, patients' characteristics, initial clinical impressions, fungal species, management, and outcomes were compared and reported.

Fonsecaea sp. was the most commonly (14%) involved species in implantation mycoses. The percentages of immunocompromised patients with implantation mycoses and invasive fungal infections were 26% and 60%, respectively. Additionally, 46% of patients with implantation mycoses had type 2 diabetes mellitus. The lesions were commonly mistaken for skin appendage tumors, skin cancers, and hyperkeratotic dermatoses. The prognosis was favorable for the implantation mycoses (83% showed clinical improvement) but bleak for the invasive fungal infections (100% mortality).

Presentations of implantation mycoses and invasive fungal infections vary widely, and immunocompromised status and diabetes mellitus are important associated factors.
