"We were able to close the gross soft tissue defect with a rotation flap from the lower lip and cheek. A modified Abbé flap  was used to reconstruct the aesthetic units of the vermilion border and the philtrum. These procedures resulted in good aesthetic and functional outcomes in only 6 months. "
[Show abstract][Hide abstract] ABSTRACT: Background
Desmoplastic trichoepithelioma (DT) is a benign appendageal tumour predominately localized on the facial skin. The histological diagnosis can be difficult in some cases. Partial malignant transformation of a DT is a rarity and a complete transformation has never been described in literature.
A DT of the upper lip was diagnosed histologically by a small biopsy 4 years previously. At presentation, the tumour had enlarged and had partly infiltrated the left side of the upper lip and subnasal region. Histological evaluation confirmed a microcystic adnexal carcinoma but without evidence of malignant transformation of the DT. It appeared that a too-small initial biopsy had led to the incorrect histological diagnosis of a benign tumour. Thus, it was necessary to perform a tumour resection and reconstruction using a two-flap technique including a rotation flap and an Abbé flap. Functional and aesthetic outcomes were good after 6 months. There were no recurrences during a 12-month follow-up.
A facial DT should be resected completely. Patients should be attended for follow-ups, keeping in mind the difficulty of making a proper histological diagnosis from small biopsies or excisions and the consequences of ablative facial surgery. However, in particular cases, subtotal defects of the upper lip region are amenable to reconstruction without gross functional or aesthetic deficits.

[Show abstract][Hide abstract] ABSTRACT: In Anbetracht ihrer stetigen Zunahme ist der Hals-Nasen-Ohren-Arzt mehr und mehr in die Frühdiagnostik und Therapie von Hauttumoren
des Gesichts eingebunden. Prominente sonnenexponierte Zonen wie Nase, Stirn, Wange und Ohrmuschel sind am häufigsten betroffen,
aktinische Keratose und Basalzellkarzinom die häufigsten Diagnosen. Chirurgische Tumorentfernung und Defektdeckung orientieren
sich an der Histologie sowie den anatomischen Besonderheiten und respektieren v.a. Dicke und Verschieblichkeit der benachbarten
Haut. Generell werden kleine bis mittelgroße Defekte in Regionen gut verschlieblicher Haut mittels einfacher Naht oder Dehnungsplastik
verschlossen. Größere Defekte oder Problemzonen betreffende Tumoren erfordern spezielle Techniken der Defektdeckung unter
Zuhilfenahme verschiedener gestielter Lappenplastiken oder freier Transplantate. Die Entfernung ausgedehnter Tumoren macht
mitunter rekonstruktive Eingriffe an N.facialis, Ductus parotideus und Ductus lacrimalis erforderlich. Gleiches gilt für
die Gerüststrukturen von Augenlid, Nase und Ohrmuschel.
As the incidence of facial skin tumors is rising, otorhinolaryngologists are becoming more and more involved in the field
of facial plastic surgery. The most common tumor locations on the head are the sun-exposed areas such as the nose, forehead,
cheek, and auricle. The most common histologic findings are actinic keratosis and basal cell carcinoma. In planning tumor
resection and defect repair, many factors, including histology, size, and localization of the tumor as well as conditions
of the adjacent skin, must be considered. The key to defect repair after tumor resection is to choose the most appropriate
technique from a range of possibilities. Because of skin laxity, most small and midsize facial defects can be closed directly
or with high-tension sutures under skin expansion. More extensive defects and those located in critical areas require pedicled
flaps or free grafts transferring skin from adjacent or distant areas. In patients with recurrent or deeply infiltrative tumors,
reconstructive procedures of the facial nerve, parotid duct, and lacrimal duct might be needed. This is also true for reconstruction
of the anatomic framework of the eyelids, the nose, and the pinna.
