Only one patient in our study, presented with erythema, also reported moderate itching as was noted in other studies Hughes et al. Another isolate came from a case of tinea nigra Crous et al.
The patients received topical treatment with Whitfield ointment, ketoconazole, bifonazole, or terbinafine.
The two cases located on the plantar region were also informative, as they concerned patients with the habit of running barefoot along the seaside, an environment horyaea high salinity and probably the natural niche of the fungus. The present article is a retrospective report of cases of tinea nigra, its epidemiological, clinical, and therapeutic features, as well as a review of the disorder.

Abstract Tinea nigra is a superficial mycosis caused by Hortaea werneckii. Most typically, it affects palms of hands but is occasionally found on other parts of the body. Symptoms include hyperchromic plaques, in which the fungus werneeckii or may not live in commensalism with other organisms Hughes et al. A case of tinea nigra palmaris in Okinawa, Japan.
In this paper, we describe the unexpected occurrence of this fungus on this special equipment usually used in close contact with human skin and mucous membranes. No teleomorph of this fungus has been found. Two isolates were recovered from two silicone skirts of scuba diving masks Hw1 and Hw2one from a strap of a mask Hw3one from a mouthpiece of a snorkel Hw4 and two from the hortaeq bag one from the bag [Hw5] and one from the bag handles [Hw6].
