Synthesis and pharmacological properties of eterylate, a new derivative of acetylsalicylic acid.

A description is given of the synthesis and main physical and chemical properties of a new derivative of acetylsalicylic acid which we have called eterylate and which is 2-(p-acetamidophenyloxy)-ethyl-o-acetoxy-benzoate. The anti-inflammatory and analgesic action of the preparation was studied and found to be comparable to that of acetylsalicylic acid and benorylate. Nevertheless, eterylate is tolerated better than the latter product, as is shown by toxicity tests and studies of the digestive system.

[The tricho-rhino-phalangeal syndrome (Giedion) (author's transl)].

We describe here six members of a family with Giedion's syndrome: sparse, fine, slow-growing hair, pear-shaped nose, cone-shaped epiphyses of the middle phalanges and variable growth retardation. There are other signs: elongated philtrum, thin upper lip, big and low set ears, medially broad eyebrows but narrow at the tip, clinobrachydactyly and marked dental caries, are as well observed in those patients. Differential diagnosis with other dysplasias is pointed out and both histological and trichological data are being valued.

[Penile leiomyosarcoma. Ultrastructural study (author's transl)].

A case of leiomyosarcoma of the penis in a farmer aged 70 is described. The patient was treated by excision/biopsy, and six months later three little tumors recurred on the glans and prepuce. A wide local excision and direct suture was carried out. No troubles happened in the next eight months. The ultrastructural study confirmed the histogenesis showing: polymorphic cells, as well as clear and dark ones, reduction of intracytoplasmic myofilaments, anisocytosis and poikilokaryosis and wide infoldings of the nuclear membrane; very vascularized areas with confluent vesicles on the endothelial cells; and intersticial haemorrhages. This tumor is included among the superficial leiomyosarcomas of "low malignancy" of McKenzie Pratt et Ross, for which simple excision that avoid mutilations is suitable. Differential histologic diagnosis includes epithelioid sarcoma of Enzinger. Leiomyosarcoma of the penis is a very rare malinant tumor. Only 15 cases have been described in the literature. A further case is reported and the previous cases are reviewed.

[Apocrine cystadenoma. About 3 observations with one balanic localization (author's transl)].

Description of three apocrine cystadenomas: two of the face and scalp and one of the glans (urethral meatus and left anterior surface of the navicular fossa) with no bibliographical precedent. From a clinico-histological standpoint the importance of objective data which make possible the clinical diagnosis is stressed allowing light microscope differentiation from eccrine hydrocystoma. The histogenesis is exposed and it appears convenient to name (eccrine or apocrine) cystadenoma the authentic cystic adenoma (among the organoid hamartoma of the cutaneous appendages, while reserving the term (eccrine or apocrine) hydrocystoma for glandular cysts. Due to the esthetic and occasionally functional repercussion, surgical excision is indicated.
