INTRODUCTION
Cutis verticis gyrate (CVG) or ”washboard” pachydermia is a specific
semiological aspect of the scalp and forehead characterized by
hypertrophy and redundancy of the integument forming “waves” separated
by deep folds. Secondary CVG have a wide variety of causes:
genodermatoses, endocrinopathies, overload disease, paraneoplastic or
tumor diseases. Lymphoblastic lymphoma (LBL) is a rare neoplasm with a
poor prognosis.1 We describe a case of CVG revealing a
T-cell lymphoblastic lymphoma (T-LBL) in a young man.
