Penile involvement in pityriasis versicolor
1Department of Dermatology, King Faisal University, Dammam, Saudi Arabia.
Abstract:
Pityriasis versicolor is a superficial fungal infection of the skin caused by Malassezia furfur (Pityrosporum orbiculare) which is a part of the normal flora of the human skin. The factors which govern the pathogenic conversion of this fungus are not fully understood but a hot humid environment is considered to be a predisposing factor and the disease is very common in tropical countries. Clinically the disease is characterized by scaly hypo- or hyperpigmented macular lesions that are typically located in the trunk, neck and upper arms. The penis is rarely affected. In this report a patient of pityriasis versicolor with involvement of the shaft of the penis is presented.
Insights
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.
- 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.
