Endovascular papillary angioendothelioma in children.

A 15-year-old boy had a tumor in his right thigh of two years' duration. A diagnosis of endovascular papillary angioendothelioma of childhood was made. This condition was first categorized as a low-grade malignancy in 1969, and was called malignant endovascular papillary angioendothelioma of the skin in childhood. Microscopically, the neoplasm is characterized by intravascular proliferation with glomerularlike appearance. The cells are small and regular, with ovoid or round nuclei; some of them show hyperchromasia and pyknosis. For the superficial form we prefer to avoid the use of the word "malignant" due to the usually good prognosis after surgical treatment.

Umbilical polyps.

We report three patients, ages 5 years, 3 years, and 4 days, with umbilical polyps. In the third child the polyp was associated with an umbilical enteric fistula. An umbilical polyp is the result of incomplete closure of the omphalomesenteric duct and becomes apparent after the umbilical cord is detached. It is a reddish tumor of a few millimeters; it seldom bleeds or is exudative. We consider it important to study every case in detail in order to exclude possible underlying embryologic anomalies such as Meckel's diverticulum and umbilical enteric fistula.

Papillary adenoma of the nipple: analysis of fifteen new cases.

Fifteen cases of papillary adenoma (florid papillomatosis, erosive adenomatosis) of the nipple were compared with forty examples of syringadenoma papilliferum, twenty-four of hidradenoma papilliferum, and one hundred of breast carcinoma metastatic to skin. Clinically, papillary adenoma of the nipple typically occurred in a female patient as an erosion, ulceration, or mass that was sometimes accompanied by serous or bloody discharge from the nipple and was frequently misdiagnosed as Paget's disease. Histologically, there was usually a papillary and adenomatous growth in the corium that connected with the surface and showed a lining of apocrine type secretory epithelium, a sometimes plasmacytic stroma, and horn cysts in the upper corium. Papillary adenoma of the nipple is often histologically misinterpreted as syringadenoma papilliferum, hidradenoma papilliferum, or low-grade adenocarcinoma, but it has received almost no attention in the dermatology literature.

[Leukocyte aggregation activity in the serum of a patient with Sweet's syndrome].

In the blood serum of a patient with Sweet's syndrome an aggregation activity of polimorphonuclear leucocytes was found in vitro. The aggregation response occurs with a latent period of one minute after the stimulation and was slow but sustained. The aggregation was totally inhibited by the hydrocortisone (500 mg./ml.). Although the polymorphonuclears of the patient aggregate normally being stimulated with C5a (ZAS), FMLP and the degranulant PMA, they remain unchanged with the patient's serum. A particular state of "leucocytic stimulation" induced by a serum agent, different from the common chemotactic factors, perhaps an immunocomplex, is postulated.

[Comparative study of 2 topical steroids preparations: desoximetasone and betamethasone dipropionate].

Effectiveness of two creams, one containing desoxymethasone 0.25%, the other betamethasone dipropionate 0.05% was compared double blind, intraindividually. The preparations were used in symmetric areas of psoriasis. Final evaluation shows desoxymethasone cream to be significantly more active concerning reduction of erythema and overall improvement of lesions.

[Spiradenoma, cutaneous cylindroma and familial multiple trichoepithelioma].

Multiple spiradenoma, trichoepithelioma and traits of cylindroma in three members of a family are studied. The relationships among these tumors are discussed. Spiroadenoma and cynlindroma have shown a close interrelation. Both conditions may exist with multiple lesions in genetic autosomal dominant inherited association with multiple trichoepitelioma.
