Item Squamous cell carcinoma of the penis: a clinicopathological study from a population with late circumcision(2019) Baydar, Dilek Ertoy; Akkaya, Hampar; Apa, Duygu Dusmez; Bal, Nebil; Demirsam, Asli; Gucluer, Berrin; Nese, Nalan; Sari, Aysegul Akder; Kirdar, Sevin; Akdogan, Bulent; Karabulut, Erdem; 31658325Squamous cell carcinoma (SCC) of the penis has been subject to only a few studies in populations where late childhood circumcision is performed. To asses clinicopathological features and human papillomavirus (HPV) status of penile SCC in men with late circumcision, eight institutions in the country volunteered to collaborate and 15 cases of penile SCC were collected from their pathology archives. The presence and genotype of HPV were determined in addition to clinicopathological features of the tumors. Findings were correlated with disease outcome. The mean age of the patients evaluated was 66.5 years. Histological subtypes were usual SCC (6/15), papillary (2/15), mixed (2/15), basaloid (2/15), acantholytic (1/15), pseudohyperplastic (1/15), and warty-basaloid (1/15) carcinomas. HPV was identified in 33.3% of samples; HPV16 was detected in 60% of positive cases and was associated with basaloid and/or warty morphology. Cause-specific 1-year and 2-year survivals were 76.9% and 54.5%, respectively. The usual subtype and nodal metastasis were associated with worse outcome (p=0.045 and p=0.047, respectively). As a conclusion, our results suggest an inclination for penile SCC to develop at a later age in a population with late circumcision than the patients from the regions of high penile cancer incidence. These men seem to have less frequent HPV association and their outcome appears poorer than other populations, although reaching substantial provision is not possible due to our limited case number.Item Proliferating Trichilemmal Tumor of the Auricula: A Very Rare Locus(2019) Coban, Kuebra; Akkaya, Hampar; Aydin, Erdinc; 31750191Proliferating trichilemmal tumor (PTT) is a rare but morphologically characteristic tumor, derived from the external root sheath. They are commonly localized as a solitary lesion on the scalp. They rarely occur in other regions. PTTs generally behave in a benign fashion, up to 20% of the lesions may undergo malignant transformation into squamous carcinoma. We present an elderly woman with a cystic swelling on the crus of auricular helix diagnosed as PTT. To our knowledge, this is the first case in the English literature, of PTT of the auricula.
