From two cases of patients presenting a cerebral aneurysm associated with a dysplasia of elastic tissue, one a Marfan's syndrome, the other an anetoderma, this paper relate the post-operative, essentially cardio-vascularly and pulmonary complexities and define the elements of the pre-operative check-up.
Histopathological sections of anetoderma-like scars from 10 patients with acne vulgaris showed a selective absence of elastic fibers around pilosebaceous follicles. This finding is similar to the histologic changes of "perifollicular elastolysis" reported by Varadi. Bacteria isolated by anaerobic and aerobic cultures of swabs of the skin surface and pus of these 10 patients, 12 others with active acne vulgaris and 8 normal subjects were studied with particular attention to Staphylococcus epidermis and Propionibacterium acnes. These organisms were analysed for production of an elastolytic enzyme which might play a role in the observed selective loss of elastic fibers. No elastolytic activity was produced by S. epidermidis or P. acnes isolated from any of these individuals. Thus, we cannot attribute the perifollicular loss of elastic fibers in acne scarring to an elastase produced by organisms. The observed absence of elastic fibers might result from tissue necrosis produced by leukocytes during the inflammatory phase, followed by collagenous scar formation without regeneration of elastic fibers.
Pseudo-scleroderma should not be confused with true scleroderma, the prognosis of which is unpredictable and often serious. Progressive acrosclerosis must be differentiated from Raynaud's disease, congenital or hereditary disorders of unknown aetiology: Werner's syndrome, acrogeria and progeria; Rothmund-Thomson's syndrome, Steinert's disease, phenylketonuria, disorders of glycogen metabolism; metabolic disorders: mutilating acropathies, scleromyxoedema, porphyria cutanea tarda; occupational and iatrogenic disorders: acroosteolysis, toxic epidermic syndrome (Spain), scleroderma-like change induced by bleomycin, chronic graft-versus-host disease; and leprosy. Acute diffuse scleroderma should not be confused with Buschke's scleroedema, sclerema neonatorum, systemic amyloidosis and scleroderma-like changes in hypothyroidism. Linear pseudo-scleroderma is suggested by the following scleroderma-like conditions: facial hemiatrophy, acrodermatitis atrophicans, melorheostosis, pseudo-scleroderma after corticosteroid injection, and cutaneous lesions in carcinoid syndrome. Scleroderma in plaque must be differentiated from hypodermitis sclerotisans, panatrophy and localized lipoatrophies, hypodermitis after vitamin K injection, basal cell carcinoma, necrobiosis lipoidica, vitiligo, chronic radiodermatitis, cutaneous lymphatic invasion. Scleroderma-like changes after drug injection (vitamin B12, progestin), anetoderma barely resemble morphea guttata.
Clinical and histological anetoderma-like changes of the skin above Malherbe's tumor (pilomatricoma) may be of diagnostic value since they have been observed 5 times in a series of 22 consecutive cases. The histological study of 46 cases of Malherbe's tumor shows a high incidence of dermal atrophy and decrease of elastic fibers in reticular dermis above the tumor, a possible consequence of cellular infiltrates surrounding the tumor and seen in half our cases.
Two patients with febrile neutrophilic dermatosis (FND) of Sweet's syndrome are described. One patient had acute myeloblastic leukaemia and FND antedated any changes in the peripheral blood. The second patient had bullous lesions which healed, with clinical cutis laxa (acquired anetoderma). In this patient FND had persisted for 8 years and histological examination of the skin lesions showed inflammation of the subcutaneous fat. To our knowledge this represents the first report of panniculitis due to FND.
BACKGROUND: The casual observation of a peritumoral edema with collagenolysis in a case of eccrine spiradenoma led us to search for similar lesions in a retrospective series of 50 spiradenomas. MATERIAL AND METHODS: Among 50 cases of eccrine spiradenomas, 36 excised with the overlying epidermis and the surrounding dermis were finally available for a conventional histologie study. RESULTS: In 14 cases, i.e. 39p. 100, we observed an edema above the tumour with thin and sparse collagen fibers and less altered elastic fibers. The clinical presentation of these 14 cases was not different from the general presentation of eccrine spiradenomas, but no precise photographical or clinical data were available. DISCUSSION: The cause of this epitumoral collagenolysis is unknown. It seems unrelated to the clear perivascular spaces often observed within the tumour lobules. It is of no help for diagnosis and may be considered as an unexplained curiosity like the elastolysis and the anetoderma seen above some pilomatricomas.
