Lymph node and visceral progression without erythroderma or blood worsening in erythrodermic cutaneous T‐cell lymphoma: nine cases.

At diagnosis of ECTL, only one patient displayed an enlarged node > 1-5 cm (not biopsied), and the median number of Sézary cells was 1440 per mm SP 3 sp (range 396-4930).

Pathological data at progression were reviewed for eight patients: skin biopsy (four patients), node biopsy (five patients) and cerebrospinal fluid (one patient). [Extracted from the article]
