Jessner's Lymphocytic Infiltration of the Skin
Jessner's lymphocytic infiltration of the skin (JLIS) is a benign, chronic T-cell infiltrative disorder characterized by erythematous papules or plaques primarily on the face, neck, and back, with a distinctive CD8+ polyclonal lymphocytic infiltrate in the dermis and no epidermal involvement.
Clinical Features
Presentation:
Demographic characteristics:
- Affects both males and females (54% female, 46% male in large studies) 2
- No clear age predilection
Clinical course:
- Chronic and recurrent
- Non-scarring
- May be persistent and treatment-resistant 3
Histopathology
Key histological features:
Immunohistochemistry:
Differential Diagnosis
JLIS must be distinguished from:
Cutaneous lupus erythematosus:
Polymorphous light eruption:
- May coexist with JLIS in some patients (10% in one study) 2
- Different histopathological features
Lymphocytoma cutis:
- Shows germinal center formation
- Different immunophenotype
Cutaneous lymphoma:
- JLIS shows polyclonal rather than monoclonal T-cell population 1
Treatment Options
Treatment options are limited, with variable efficacy:
First-line therapy:
Other treatments:
Prognosis
- Generally excellent prognosis with no progression to malignancy
- No documented progression to cutaneous lupus erythematosus or lymphoma 2
- Chronic course with potential for recurrence
- May be refractory to treatment in some cases 3
Clinical Pearls
- JLIS is a distinct entity and not a variant of lupus erythematosus or polymorphous light eruption
- Biopsy is essential for diagnosis, showing the characteristic dermal lymphocytic infiltrate without epidermal changes
- Persistent indurated plaques of the face may represent a variant of JLIS that is particularly resistant to treatment 3
- Pulsed dye laser therapy may be considered as a first-line treatment option with minimal side effects 4
