Squamous carcinoma of the external ear

Predicting the pattern of regional metastases from cutaneous squamous cell carcinoma of the head and neck based on location of the primary

“…A multicenter study involving our institution previously recommended a supraomohyoid neck dissection in patients with anterolateral primaries and a comprehensive neck dissection for posterior primaries 9 while several other authors have recommended selective dissection of level I-II or I-III nodes in this setting regardless of the site of the primary tumor. [10][11][12] The most important outcome in this study revolves around the absence of level IV or V metastases in cPþN0 patients with pathologically negative nodes in levels II and III. Based on these findings, we support the use of elective level II/III dissection to stage the neck and determine the extent of adjuvant radiotherapy.…”

“…A multicenter study involving our institution previously recommended a supraomohyoid neck dissection in patients with anterolateral primaries and a comprehensive neck dissection for posterior primaries 9 while several other authors have recommended selective neck dissection in this setting without taking into account the location of the primary tumor. [10][11][12] The primary aim of this study was to determine if a more selective approach to the neck, dissecting only levels II and III in cPþN0 patients is feasible. To test this hypothesis, we analyzed the pattern and frequency of regional lymph node metastases from cutaneous SCCHN according to the location of the primary site.…”

“…Results. Thirty of 79 patients (29 male,one female;average age 77.2 years,range 54-99 years) with cutaneous malignancies of the external ear were diagnosed as SCC (n=32 SCC).A total of 17 SCC were smaller than 2 cm,12 were between 2-5 cm,and three were larger than 5 cm.Only two patients had regional nodal disease,none had distant metastases.The anesthesiological risk was estimated according to the recommendations of the American Society of AnesthesioloFernmetastasen hatte keiner.Das Anästhesieri-siko nach der American Society of Anesthesiologists (ASA) lag bei 16 [1,2,5,14,24] des Mannes [8,9] handelt.Helix und Anthelix sind besonders gegenüber UV-Strahlen exponiert und stellen daher in unserer Studie, wie bei anderen Autoren [5,15,21] auch, die häufigsten Lokalisationen der PEC an der Ohrmuschel dar (63%).…”

“…Die meisten PEC der Ohrmuschel waren, wie bei Byers et al [5] auch, in unserer Studie lokal wachsend, ohne Infiltration der Ohrmuschel angrenzender Regionen und ohne Lymphknoten-oder Fernmetastasen. Insofern erscheint eine Diskussion über die Radikalität der Therapie unter Einbezug des Patientenalters und Allgemeinzustandes legitim.…”
