[Stewart-Treves pseudo-syndrome caused by cutaneo-lymphatic metastases of contralateral breast carcinoma].

The pathogenesis of Stewart-Treves syndrome remains controversial: angiosarcoma or epithelial cell metastases from a mammary carcinoma? The case reported here, with clinical signs of Stewart-Treves syndrome on one side and mastectomy for carcinoma on the other side of the body, revives the debate. Case-history. The patient was an 89-year old woman whose left breast had been removed in June, 1981 for carcinoma with lymph node involvement. One year after the operation, multiple lymphadenopathy developed in her right armpit and subclavian region. In December, 1984, her right arm became swollen by lymphoedema, while Kaposi-like and nodular skin lesions appeared on her right upper chest and upper back and on her right shoulder and arm. Radiography of the chest showed right pleural effusion, bronchial lymph node enlargement and a reticulate image in the right lung. In spite of chemotherapy, the patient died in April, 1985. Pathology. Pathological examinations included standard histology (HPS, PAS and Gordon-Sweet staining), immunohistochemistry, using anti-factor VIII, anti-keratin KL1 and anti-EMA antisera, and electron microscopy. Results. Irrespective of the skin area biopsied, the histological images were always the same, showing carcinomatous lymphangitis with a varying degree of invasion of the surrounding dermis. Staining of the reticulum enhanced the vascular basal membranes but did not mark the intraluminal tumoral cell population. Post-mortem examination confirmed that the malignant lymphangitis extended to the lung tissue, the oesophageal wall and the adrenal glands, and that the axillary and subclavian lymph nodes were invaded by metastases.(ABSTRACT TRUNCATED AT 250 WORDS)

[Early congenital syphilis: apropos of 5 cases].

Congenital syphilis has in large part disappeared in countries where antiveneral legislations and preventive measures are well developed. In France, although there is no declaration of congenital syphilis between 1971 and 1983 in the official statistics of the Paris region, congenital syphilis is nevertheless mentioned as sporadic cases. The authors report here five cases of precocious congenital syphilis collected from august 1981 to december 1982 by a department of antiveneral consultations in the Paris region.

[Subcutaneous localizations of Castleman's pseudolymphoma. Review of the literature apropos of a case].

The angiofollicular lymphoid hyperplasia, first described in 1954 by Castleman in the mediastinum, is a quite rare pseudolymphoma where there are few subcutaneous localizations. Since 1954, more than 300 observations were published including mediastino-pulmonary forms (about 60 p. 100 of the cases) intra-abdominal forms (15 p. 100 of the cases) and superficial forms which represent 25 p. 100 of the cases and associate superficial ganglionic, intra-muscular and subcutaneous localizations. The authors report the observation of a 44-year-old negro who had a subcutaneous tumefaction of the left elbow which appeared recently without a functional sign nor a biological change. The histological findings allowed the diagnosis of Castleman's pseudolymphoma in a hyalino-vascular form or Flendrig's type II. The evolution was marked a few weeks later by a local recurrence of which a second surgery has secured the recovery. The detailed study of the 76 cases of Castleman's superficial pseudo-tumours published in the literature allows us to recall the features of this disease which affects especially the young adult without prevalence of sex at about 25 years old. The circumstances of discovery are univocal, isolated palpable subcutaneous tumefaction in most of the cases. The localizations are distributed by decreasing incidence as following: latero-cervical, axillary, sus-clavicular, inguinal, vulvar, abdominal wall, shoulder, arm, forearm with a few bifocal forms. The histological aspect associated a predominant lymphoid population and vessels with fibro-hyalinous wall which morphological variations have permitted to individualize three forms: a plasmocytic form or Flendrig's type I which should be a stage of beginning often associated with hematological changes, a hyalino-vascular form or Flendrig's type II more frequent and a mixed form or intermediary type. The immunofluorescence, histo-enzymology and immunohistochemistry studies reveal a changeable polyclonal plasmocytosis and a predominance of T-suppressors in the lymphocytic population. The histological differential diagnosis of the superficial forms of the Castleman's pseudolymphoma is rarely set with certain lymphoma in case of ganglionic localization. On the other hand isolated subcutaneous localizations must be distinguished of the Kimura's disease and of the angiolymphoid hyperplasia with eosinophils where the vessels have a different morphology. The evolution is favorable in most of the cases and surgical exeresis insures the recovery.(ABSTRACT TRUNCATED AT 400 WORDS)

[Developmental aspects of nevus spilus: review of the literature apropos of 7 cases].

The nevus on nevus is a dischromic lesion with a double component made of a pigmented, pale-brown coloured spot, most often congenital punctuated by macular or discretely papular darker elements, with a usually later setting-up and conventionally characterized by an absence of evolutivity. A series of seven cases is reported of whom three present a very peculiar evolution: A 37 years old man is taking a medical advice for a nevus on a congenital nevus on the right buttock on which appeared later on a blue-coloured, lightly sensitive nodule which clinically calls to mind the diagnosis of a blue nevus: the surgical exeresis is refused by the patient. A little girl, born in 1972, has since her birth a nevus on nevus of her right fore-arm; in 1975 and 1976 appeared successively on this lesion three nodules evocative of Spitz melanoma (fig. 4), which are surgically removed; histologic examination confirms the clinical diagnosis (fig. 5). A woman, aged 38, presents a big nevus on congenital zosteriform nevus of the right lower limb; since 1982, one of the dark elements situated on the lower third of the leg is progressively spreading and becoming polychromic (fig. 6); the clinical suspicious of superficial spreading malignant melanoma is confirmed by the histologic examination. In the literature, the terminology aiming to call this kind of nevic pale brown spot recovered by darker macules is not quite clear, as it was already emphasized by Stewart in 1978 (27). Indeed, numerous different denomination are found in it: "nevus spilus", nevus on nevus", "spotty nevus" "speckled lentiginous nevus", "speckled nevus "spilus".(ABSTRACT TRUNCATED AT 250 WORDS)
