Anatomical variations of the carotid arterial system have a great impact on surgical approaches to the neck and radiological imaging interpretation. Although reports on internal carotid artery dolichoarteriopathy (kinking, tortuosity, coiling) have been reported, no report on dolichoarteriopathy of the external carotid artery has been described. Herein, we report a case with concurrent bilateral kinking of the extracranial part of the internal carotid artery associated with extensive calcifications in the relatively high-located carotid bifurcation and coiling with tortuosity of the external carotid artery in a male cadaver - an entity that has not yet been reported. The variation presented should be kept in mind during various surgical procedures in order to decrease possible iatrogenic or surgical complications.

The trichilemmal carcinoma is a rare low-grade malignant lesion originating from hair follicle cells that usually occurs on sun-exposed skin of older individuals. A differential diagnostic is required with other skin carcinomas. We report two cases of trichilemmal carcinoma admitted at the Emergency University Hospital of Bucharest, Romania, in 2012, one of these cases being localized in the periocular area and the other one resembling a cutaneous horn. These cases present several unusual aspects that are rarely described in the literature namely the site of the tumor which in the eyelid, development of a cutaneous horn, IHC tests which revealed EMA (epithelial membrane antigen) positivity in tumor cells. Considering that this type of tumor seldom develops metastases or local recurrences, and all the cases had free margins, there was no adjuvant therapy.
