A clinical case of a female patient with a black spot on the palm of her left hand is presented. The infection was due to a black fungus identified as Hortaea werneckii, the aetiological agent of tinea nigra palmaris. ⋯ In this case, the patient was treated with econazole locally applied during one month, with complete remission of the lesions. In conclusion, the early diagnosis of this disease is very important since the mycology procedures are fast and non-invasive and cure is obtained with local treatment.
