Intimal thickenings in the inferior epigastric artery and coronary bypass.

Objective: To investigate the relationship between the inferior epigastric artery and the development of pathological intimal thickenings.

Material And Methods: The inferior epigastric artery structure was studied with conventional histology techniques, histochemistry, immunohistochemistry and morphometry.

Results: The inferior epigastric artery develops 2 types of intimal thickenings: physiological and pathological.

Contributions to the study of the foetal development of physiological intimal thickening in the human uterine artery.

The morphological study of the development of "intimal thickenings" of the human uterine artery in physiological condition was performed on 72 uterine arteries obtained from foetuses from the 12th week of gestation up to birth. Our results indicate that intimal thickening is formed by the migration and displacement of mesenchymal cells around the site of origin of collateral vessel from uterine mesothelium. These cells firstly differentiate into the myoblasts and then into the myocites.

Squamous cell carcinoma, malignant melanoma and malignant fibrous histiocytoma arising in burn scars.

The most common cancer arising from an old burn scar is squamous cell carcinoma, while malignant melanoma is rare. There are only four reports in the literature on the combination of the more common tumour with a malignant melanoma and only two cases of malignant fibrous histiocytoma alone. This paper reports the first occurrence of the combination of all three types of cancer in burn scars of the same patient.

Reconstruction of the tragus after tumour excision.

Reconstruction of the tragus is very difficult to perform and most techniques are described for the treatment of microtia where remnants of ear are used. The goal always consists in achieving a prominence that covers the canal. We present a novel and safe method, based on the vascularity of the lobule, that also provides a good appearance.

A combined flap technique for earlobe reconstruction in one stage.

Many of the techniques available for earlobe reconstruction require that the rest of the ear is in continuity with retroauricular skin and they usually need two stages; in some cases a graft is also required. We present a method to create an earlobe in one stage and without grafts, illustrated by one case report. The technique is a combination of the flap techniques of Davis and Zenteno Alanis, using an extended retroauricular flap together with an anterior ear flap.
