Objective: To study the exact frequency and the histological features of cutaneous intolerance to mechlorethamine (CIM) hydrochloride therapy in patients with cutaneous T-cell lymphomas, including Langerhans cell histiocytosis. Design: A multicenter prospective study was conducted from January 1, 1994, to May 31, 1996, in 12 different hospitals in France. Patients: Of the 52 patients with cutaneous T-cell lymphomas or Langerhans cell histiocytosis, 35 were men and 17 were women, aged 18 to 87 years. Of the 52 patients, 35 had mycosis fungoides, 8 had nonepidermotropic cutaneous lymphoma, 7 had lymphomatoid papulosis, 1 had Sézary syndrome, and 1 had Langerhans cell histiocytosis. Methods: Patients were treated with topical applications of a 0.02% aqueous solution of mechlorethamine. The diagnosis of CIM was determined by the presence of erythema and pruritus. Patients who developed CIM underwent closed patch testing with three 10-fold dilutions of 0.02% mechlorethamine solution. A positive patch test result was the presence of erythema and pruritus, a weak result was the presence of simple erythema without pruritus, and a negative result was the absence of erythema and pruritus. Skin biopsy specimens from patients with positive patch test results were obtained in patients who developed CIM. The biopsy specimens were reviewed, and the results determined by 2 pathologists (E.T. and J.W.). The histopathological findings were classified in 3 categories: (1) spongiotic dermatitis, (2) irritant dermatitis, and (3) insignificant or normal. In September 1998, the referring physicians were contacted if mechlorethamine therapy had been continued in patients with CIM. Results: Of the 52 patients, 43 were evaluated for tolerance to mechlorethamine therapy. Of the 43 patients, CIM developed in 23, from 4 days to 9 months after the initiation of mechlorethamine therapy. Of those 23 patients, CIM developed within 3 months in 21 and within 1 month in 13.
