Erdheim-Chester disease is a rare, non-Langerhans cell form of histiocytosis characterized by osteosclerosis of the metaphyseal regions of long bones, diabetes insipidus, proptosis, and retroperitoneal fibrosis. The latter usually involves the perirenal area and leads to hydronephrosis. Periaortic fibrosis is less frequent. We describe 3 unusual cases of Erdheim-Chester disease with periaortic fibrosis involving the whole aorta and leading to a "coated aorta" appearance on computed tomography scans. Faced with such a singular "coated aorta," bone scintigraphy can be very helpful when searching for Erdheim-Chester disease.

AIMS: Gamma-delta (gammadelta) T-cell non-Hodgkin's lymphomas (NHLs) usually present with liver, spleen and marrow infiltration. Lymph node involvement by gammadelta T-cell NHL has been rarely documented so far; its histological pattern needs to be further defined. METHODS AND RESULTS: Two cases of nodal gammadelta T-cell NHL are reported: case 1, a 44-year-old man, presented with cytomegalovirus retinitis and superficial lymphadenopathies. Histological analysis of an inguinal lymph node showed complete destruction by a diffuse pleomorphic lymphoid proliferation, which was positive for CD2, CD3, CD43, CD45, TIA-1 and granzyme B, and displayed a gammadelta phenotype (deltaTCR1+, Vdelta1+, Vdelta2-, Vdelta3-, betaF1-). Bone marrow was normal. Case 2, a male 24-year-old patient with a history of renal transplantation, presented with hepatosplenomegaly and supraclavicular lymph node enlargement. Lymph node architecture was globally preserved. Peripheral sinuses contained scattered nests of medium-sized irregular lymphoid cells. Bone-marrow was infiltrated. Phenotype showed positivity for CD2, CD3, CD45 and TIA1 and expression of gammadelta TCR (deltaTCR1+, deltaV1+, deltaV2-, deltaV3-, betaF1-). Both patients died a short time after diagnosis. CONCLUSIONS: These observations suggest that at least two forms of nodal gammadelta T-cell NHL may be encountered: one mimicking classical alphabeta T-cell NHL, with diffuse pleomorphic cell proliferation, and one displaying sinusoidal neoplastic infiltration suggesting a close relationship with hepatosplenic gammadelta T-cell NHL.

Arterial reactivity leading to acute thrombosis at the site of a needle stick injury has never been described during antiphospholipid syndrome. The authors report a case characterized by a succession of thrombotic events occurring during or immediately after arterial angiographies or arterial surgery, in which catastrophic arterial reactivity can be strongly suspected. In this particular patient, it can be postulated that damage to the endothelial cells of the vessels injured during manipulation may have precipitated or aggravated the preexisting susceptibility to thrombosis.

The pathophysiology of migraine remains unclear. To incriminate a comorbid factor is always hypothetical, even if suppression of this factor appears to prevent the migrainous attacks. In our patient, treatment of coeliac disease coincided with total disappearance of severe migraine attacks. Moreover, the coeliac disease was first revealed during the evaluation of a migraine with aura.
