Penile tuberculoid leprosy in a five year old boy

Area of Science:

• Dermatology
• Infectious Diseases
• Microbiology

Background:

• Leprosy, a chronic infectious disease caused by Mycobacterium leprae, primarily affects the skin and peripheral nerves.
• Early diagnosis and treatment are crucial to prevent disability and transmission.
• Contact tracing and examination are vital components of leprosy control programs.

Observation:

• A 5-year-old child, a contact of a lepromatous leprosy patient, presented with a tuberculoid lesion on the penile shaft.
• Clinical suspicion of borderline tuberculoid leprosy was confirmed by histopathology as subpolar tuberculoid leprosy.
• The child's father was a recently diagnosed lepromatous leprosy case undergoing multidrug therapy.

Findings:

• Histopathological examination confirmed subpolar tuberculoid leprosy in the child.
• The study suggests potential reasons for the lesion's specific localization to the penile shaft.
• Evidence points towards the skin as a significant route for tuberculoid leprosy transmission among contacts.

Implications:

• This case underscores the importance of examining all contacts, including children, of leprosy patients.
• Understanding transmission routes, such as skin contact, can refine public health strategies for leprosy elimination.
• Early detection and management of leprosy in contacts can prevent disease progression and further spread.
