Cause

Also known as lipomelanotic reticulosis or Pautrier-Woringer disease, represents a rare form of benign lymphatic hyperplasia associated with most exfoliative or eczematoid inflammatory erythrodermas, including pemphigus, psoriasis, eczema, neurodermatitis, and atrophia senilis.

Diagnosis

Dermatopathic lymphadenopathy is diagnosed by a lymph node biopsy. It has a characteristic pattern of histomorphology and immunohistochemical staining:

Paracortical histiocytosis
Melanin-laden macrophages
Eosinophils
Plasma cells (medulla of lymph node)

Differential diagnosis

Treatment

The treatment is based on the underlying cause.
