Leprosy physical examination

Although the findings on physical examination may vary depending upon the subytpe of leprosy, common findings include hypopigmented skin lesions, thickened dermis, and loss of sensation.

Leprosy may have different presentations, depending on the immune response of the host. The disease often affects the skin, nerves, and mucous membranes in different patterns and with different intensities. The possible physical findings of the disease include:^[1][2][3][4]

• Fatigue is often present
• Weight loss is often present
• Anhidrosis may be present

• Fever may be present

• Painless cuts, wounds and burns are often present, predominantly on the hands, arms, legs and feet
• In tuberculoid or paucibacillar leprosy, larger hypopigmented or erythematous macules are often present
• In borderline tuberculoid or paucibacillar leprosy, macules are often sharply defined with a central clearing, more numerous than the in previous category and generally located unilaterally.
• In mid-borderline andlepromatous or multibacillar leprosy, central area of the lesions is often anesthetic
• In borderline lepromatous leprosy, lesions are often erythematous macules and/or papules, symmetrically distributed throughout the body. Nodular lesions are often present and there may be areas of normal skin between the lesions, however, the margins of the lesions are diffuse, instead of well-defined.
• In lepromatous leprosy, lesions are often generalized throughout the body and may be of macular, papular or nodular origin. There is often loss of body hair, particularly of the eyebrows and eyelashes
• In indeterminate leprosy, lesions are often hypopigmented or erythematous macules with diminished sensation

• Facial paralysis may be present
• Lack of eyebrows and eyelashes may be present
• Lumps are often present, predominantly on the face

• Lagophthalmos is often present
• Dry corneas are often present
• Corneal abrasion is often present
• Corneal ulceration is often present
• Blindness may be present

• Nodular thickening of the earlobes may be present

• Saddle nose may be present, particularly in lepromatous leprosy
• A perforated nasal septum may be present
• Invasion of the nasal mucosa may be present, particularly in lepromatous leprosy, leaden to nasal stuffiness
• Epistaxis may be present

• Weakness of the hands and feet may be present
• Claw fingers are often present
• Foot drop is often present
• Edema of the hands and feet may be present
• Fractures may be present

• Sensory and/or motor loss are often present, predominantly in skin lesions and in territories located distal to enlarged peripheral nerves:

• In tuberculoid leprosy this often occurs in the vicinity of the skin lesion
• In lepromatous leprosy this loss is often more generalized

• Paresthesias are often present, predominantly in the hands and feet
• Tender and/or enlarged peripheral nerves are often present
• Painful neuropathy may be present
