Hendersonula toruloidea infection is present in Thailand, where the clinical picture of tinea pedis is scales 61%, erythema 22%, maceration 10.8%, and hyperkeratosis 9%. The diagnosis was confirmed by repeated isolation of H. toruloidea. The slow-growing type was found more often than the fast-growing in the ratio of 2.8:1. In patients with H. toruloidea infection, skin test with Hs antigen of 1:10 was positive. Griseofulvin sensitivity test revealed that the MIC of 20 cultures was more than 100 micrograms/ml. Only 2 out of 93 cases (0.02%) were cured with half-strength Whitfield ointment for 4 months. Pathomechanism of the infection is being studied.

A 39-year-old Thai man had eczema on the left groin accompanied by asymptomatic white nodules on the public hair for two weeks. Examination with the Wood's lamp, microscopic examination, culture and biochemical testing showed organisms compatible with Trichosporon beigelii. The diagnosis of "White Piedra" was made, and this is the first case of White Piedra to be reported in Thailand.

Subcutaneous chromomycotic absesses due to phialophora gougerotii in a 50-year-old woman were characterized by subcutaneous abscesses adhering together through fistulous tracts, rupturing and leaving black crusts over multiple sinuses mimicking mycetoma. Reinfection occurred in contaminated excised lesions. Intradermal inoculation in different anemic patients caused abscesses in 14 days and healed without therapy in eight weeks. No spreading to other organs was found after intraperitoneal inoculation of mice for eight weeks.
