Ayesha Munir, Nighat Akbar, Farid ur Rehman


Objective To determine the frequency of hair loss in the lesions of pityriasis versicolor.


Methods It was a cross-sectional study carried out at the outpatient department of dermatology, Fauji Foundation Hospital, Rawalpindi, Pakistan over six months period after approval from the hospital’s ethical committee. Informed consent was obtained from participants. Two punch biopsies were taken from each patient, one from lesional and other from nonlesional skin under local anesthesia. The biopsy specimen included at least one hair or follicular ostium. Biopsy specimens were observed histopathologically for evidence of hair loss by making a comparison of lesional specimen with the nonlesional specimen. Frequency of hair loss was also documented.


Results Histopathological evaluation of biopsy specimens from the lesions of pityriasis versicolor demonstrated hair loss in a significant number of patients (57.6%) when compared to biopsy specimens from nonlesional skin.


Conclusion Pityriasis versicolor can cause hair loss in a significant number of individuals.
