Neurofibrillary tangles induced by a sclerosing angioma.

A sclerosing angioma in the frontal cortex of a 40 year old woman produced local pressure, with resulting alteration of the blood-brain barrier. In the narrow cortical zone affected by chronic pressure, the level of aluminum was significantly elevated; and all neurons had neurofibrillary tangles of the Alzheimer type.

Sclerosing angioma of the lung. Case report and electron microscope investigation.

Electron microscopy of a sclerosing angioma of the lung, a coincidental finding in the upper lobe of a 32-year-old woman. The rare, benign tumor, whose vascular proliferation by light microscopy is reminiscent of an angioma, exhibits a clear epithelial structure by electron microscopy. The tumor may develop out of immature pneumocytes. The paper discusses histogenesis and problems of differential diagnosis (potential confusion with carcinomas).

Treatment of angiomas with sclerosing injection of hydroxypolyethoxydodecan.

The authors discuss the indications for hydroxypolyethoxydodecan in the sclerosing treatment of angiomas, with particular reference to cavernous, venous, and evolutive angiomas (ie, immature angiomas that fail to involute by eight to ten months). Moreover, the sclerosing agent may be employed, in connection with embolization and subsequent surgery, in arteriovenous angiomas with a relevant cutaneous-subcutaneous development. The authors have successfully used the "interstitial" sclerosing technique, according to Andrews' method. This technique involves interstitial injections to obtain the sclerosis of the thin threads of fibrous tissue stroma between the blood vessels. The sclerosing therapy may cause the complete regression of "low flow" angiomas or, at least, a partial reduction that simplifies the ensuing surgical excision. In the case of partial regression of the angioma obtained with the sclerosing therapy, the surgery of the remaining angioma causes a lesser degree of bleeding (especially in areas that do not particularly lend themselves to surgical exploration, ie, the oral cavity); an increased reliability in the radicality of the intervention (due also to the reduced size of the lesion); and better results from an aesthetic-functional point of view.

[Sclerosing tufted angioma. Apropos of 4 cases involving lower limbs].

BACKGROUND: Tufted angioma belongs to the family of vascular skin proliferations. Clustered capillaries is the characteristic histological feature. Classically, tufted angioma is an acquired disease observed in children or young adults with lesions predominating on the neck, the shoulders and the upper trunk. CASE REPORTS: Four children were seen for flat skin lesions which were either initially or secondarily erythematous. The lesions were observed at birth or within the first weeks of life. In all 4 cases, the lesions progressed by infiltration, leading to sclerous plaques within a few weeks. The hip area was involved in case n(o) 2 and the thigh in the other cases. Pathology reported tufted angioma. A repeated biopsy 4 years after the first biopsy demonstrated the progressive nature of the fibrosis in case n(o) 2. Magnetic resonance imaging, performed in 3 of the 4 cases, demonstrated deep penetration of the vascular proliferation. The lesions were in contact with bony structures in case n(o) 2, reached the hypodermis in case n(o) 3 and infiltrated between the adducter muscles in case n(o) 4. DISCUSSION: Among tufted angiomas, there is a clinical variant characterized by very early discovery (congenital or within the first months of life), preferential localization on the lower limbs and progression to sclerosis. Although non-specific, hypersudation and lanuginous hypertrichosis are also highly suggestive signs. The main clinical and histological differential diagnosis is angio-eccrine hamartoma and, to a lesser degree, Kaposi hemangioendothelioma which does not predominate on the lower limbs. This particular clinical presentation of tufted angioma should lead to wide and sufficiently deep biopsy to allow precise diagnosis prior to initiating therapy. The possibility of spontaneous involution would allow abstention with regular surveillance to detect reactivation and progression or functional impairment. Such unfavorable progression has lead certain authors to propose high-dose systemic corticosteroid therapy or alpha-interferon.
