Pityriasis versicolor, a fungal skin infection, rarely affects the penis. This report details a case of pityriasis versicolor on the penile shaft, highlighting an unusual presentation of this common condition.

Area of Science:

  • Dermatology
  • Mycology
  • Infectious Diseases

Background:

  • Pityriasis versicolor is a superficial fungal infection caused by Malassezia furfur, a common skin commensal.
  • Pathogenic conversion factors are unclear, but hot, humid climates predispose individuals to this infection.
  • The condition typically presents on the trunk, neck, and upper arms.

Observation:

  • This report documents an unusual case of pityriasis versicolor.
  • The patient presented with characteristic scaly, hypo- or hyperpigmented macular lesions.
  • Lesions were observed on the shaft of the penis, a rare site of involvement.

Findings:

  • Malassezia furfur can cause pityriasis versicolor on the penile shaft.
  • The clinical presentation of scaly, pigmented lesions was consistent with pityriasis versicolor.

Related Experiment Videos

  • Penile involvement represents an atypical manifestation of this superficial fungal infection.

    • Implications:

    • This case expands the known clinical spectrum of pityriasis versicolor.
    • It underscores the importance of considering fungal infections in unusual dermatological presentations.
    • Further research may elucidate specific factors contributing to rare site involvement.
