title: [Angiolymphoid hyperplasia with eosinophilia. Extensive form associated with thrombopenic purpura].
abstract: The authors report a case, on a 59-year-old female patient, of angiolymphoid hyperplasia with eosinophilia (AHE) associated to a thrombopenic purpura (TP) of which the evolution is parallel. The clinical aspect is made of sub-cutaneous nodules of various sizes (1 or 2 cm on an average) and of more superficial, erythematous, sometimes telangiectatic, pseudo-angiomatous nodules. There are (about) 25 nodules, located on the face, the neck, the arms and the thorax, sometimes pruriginous: the rest of the examination is negative excepting axillary and inguinal small size lymph nodes and of a dermographism. The anatomopathological examination in optical microscopy, shows a dermo-epidermal lymphocytic infiltrate with which mingle numerous eosinophilic leucocytes. The dermal vessels are very altered, with a swelling endothelium and a proliferation of endothelial and perithelial cells filling up in large part the vascular section. The biological investigation show essentially: a slight and altering hypereosinophilia (between 500 and 800/mm3); a low amount of blood-platelets (between 95,000 and 130,000/mm3); an increase of the seroconversion enzyme of angiotensin (75 UI; N less than 52 UI); are normal or negative: ESR, protein electrophoresis, immunological tests. The diagnosis of AHE is held back and the clinical evolution is done in several stages: under general corticotherapy (prednisone 1 mg/kg/j): progressive decrease of the nodules, but stopping of the therapy by the patient after 4 months; testing of treatment by thalidomide (100 mg/day) interrupted after 2 weeks because of the aggravation of the thrombopenia (25,000/mm3); occurrence of a thrombopenic purpura (TP) (amount of platelets 10,000/mm3) without a serious haemorrhagic syndrome, evolving in a parallel way to the outbreak of AHE.(ABSTRACT TRUNCATED AT 250 WORDS)
