[Nocardia brasiliensis leg ulcer and nodular lymphangitis in France].

INTRODUCTION: Nocardia brasiliensis is a very rarely reported cause of chronic phagedenic ulcerations. We report the case of an elderly woman who developed such an infection after falling on her right leg on the road in the Bresse country (an essentially agricultural and bovine-cattle breading region) and developed a chronic phagedenic ulcer secondarily complicated by nodular lymphangitis of the thigh. CASE REPORT: A 75 year-old woman fell on her right leg on the side of the main road outside her hamlet in the Bresse country and secondarily developed a chronique phagedenic ulceration. We first considered her as suffering from pyoderma gangrenosum. A complete scanning only revealed an autoimmune thyroiditis and a rapidly healing gastric ulceration, and none of the treatments, either local or systemic, helped the skin condition to heal. After 3 weeks of application of a local corticoid ointment, the patient developed fever, general malaise, an exacerbation of her wound and an infiltration of the skin round her knee, together with nodular lymphangitic dissemination. A supplementary bacterial swab disclosed massive proliferation of a slow-growing Gram-positive bacillus, which proved to be Nocardia brasiliensis, together with a methicillino-sensitive Staphylococcus aureus. The treatment with sulfamethoxazole-trimetoprim gave a rash after 12 hours and was changed to amoxicillin and clavulanic acid, which rapidly proved to be permanently effective. DISCUSSION: The revelation of this particular slow-growing bacteria is difficult and requires bacterial swabs. Nocardia brasiliensis is relatively rare in primary skin ulcerations and we discuss the reasons why an elderly women should find this bacteria on the road outside her hamlet in the French countryside. This particular infectious condition requires general scanning, to make sure that the primary skin condition does not extend to other organs. We review the therapeutical options for patients who exhibit allergic reactions to the classically effective antibiotic drugs.

D.N.C.B. for malignant melanoma: significance in the treatment strategy.

2-4 Dinitrochlorobenzene (D.N.C.B.) is a synthetic primary allergenic molecule which has proved to have at least two useful clinical applications as regards neoplastic conditions. As a diagnostic measure, it serves in the detection of global alterations of cellular immunity. As a therapeutical measure, its epicutaneous use has proved to stimulate immune defence reactions loco-regionally if not systemically. This second property finds an important field of application in the treatment of malignant melanoma (M.M.), the reason for this being that natural immune defence reactions seem to play an important role in the natural history of this type of tumor. This review collects literature data on the therapeutical use of D.N.C.B: which, together with personal cases, show that this type of treatment may be proposed as a palliative measure for the treatment of skin metastases or as an adjuvant measure for surgery in the treatment of M.M. with surgically accessible metastases. D.N.C.B. appears to be part of a new therapeutical group, the Biological Response Modifiers (B.R.M.), and would seem to have a place in future treatment protocols associating B.R.M. with other treatment methods (e.g. chemotherapy).
