The paper presents information regarding a rare skin disease Gottrons carcinoid papillomatosis, for the first time described in 1932 by German dermatologist H.A. Gottron. Its development is associated with the preceding chronic dermatoses and disturbance of circulation in the lower extremities. Morphologically, Gottrons carcinoid papillomatosis of the skin is characterized by the development of pseudoepitheliomatous hyperplasia of epidermis. Clinical picture, dermatoscopy, ultrasound and histological studied were used for diagnosis. This disease should be differed from high differentiated squamous cell carcinoma of the skin, chronic ulcerous pyodermavegetans, lupus verrucosis, chromomycosis. We described our own clinical observation of Gottrons carcinoid papillomatosis of the skin, developed against a background of psoriasis.

Objectives: Oral squamous cell carcinoma (OSCC) is the most common oral malignancy with low survival as it is very often diagnosed at an advanced stage, which is why the accurate profiling of the tumor is essential. The aim of this study was to, for the first time, compare in OSCC the frequency of AR, VEGF, MMP9, HiF1beta and Ki67 between the non-metastatic and metastatic disease. Materials and Methods: In the study, 96 non-metastatic and 91 metastatic OSCC patients were analysed for AR, VEGF, MMP9, HiF1beta and Ki67 levels by immunohistochemistry. Results: All of the tested biomarkers significantly differed between non-metastatic and metastatic disease. A significant association was found between >/=20% AR positive epithelium cells in cytoplasm, Ki67 and VEGF in cancer stroma. Ki67, HiF1beta, VEGF and MMP9 were significantly associated with TNM stages. Conclusion: Our results show for the first time an interplay between AR, VEGF, MMP9, HiF1beta and Ki67 in OSCC which may contribute to better diagnostics and therapy selection.

Well Differentiated

Differentiating hypertrophic lichen planus (LP) from well-differentiated squamous cell carcinoma (SCC) is a histological challenge given the numerous histopathologic similarities between SCC and pseudoepitheliomatous hyperplasia (PEH) arising in the setting of hypertrophic LP. Multiple reports have shown that SCC can arise from hypertrophic LP not infrequently, but that the LP-to-SCC sequence is poorly understood, and many cases defy diagnosis due to histologic similarities. However, there are several clinical clues and histopathologic details that have shown to have some value when trying to ascertain the correct diagnosis. To the contrary, immunohistochemical tests have shown little promise in differentiating hypertrophic LP from SCC. Although multiplex PCR has shown some potential in differentiating PEH from SCC, this has only been in the setting of patients diagnosed with prurigo and lichen simplex chronicus, but not necessarily in the case hypertrophic LP.

Erosive pustular dermatosis of the scalp (EPDS) is an uncommon disease and primarily affects older men who have photodamaged bald scalp, as was confirmed by our case series. EPDS is probably an overlooked disease, whose diagnosis is often missed because of a higher incidence of other cutaneous diseases affecting the same area and usually secondary to chronic actinic damage, such as actinic keratosis, basal cell carcinoma, and squamous cell carcinoma. For the first time, we report a case series of misdiagnosed EPDS with the aim of understanding why a diagnosis of EPDS was initially missed and try to give some tips to avoid future diagnostic delay.

Negative Biopsy

Cutaneous squamous cell carcinoma is the second most common form of skin cancer and accounts for 20% of cutaneous malignancies. We report the case of a patient who presented with a complaint of nonhealing wounds following radiation therapy for the treatment of noninvasive squamous cell carcinoma of both lower extremities. Initial biopsies of the wounds were benign. However, a second biopsy performed approximately 2 months later was found to be positive for invasive squamous cell carcinoma. This case uniquely exemplifies that all nonhealing wounds should be viewed with a critical eye for possible malignancy even in the presence of previous negative biopsy. This is especially true for radiation wounds that may be prone to malignant transformation or recurrence. (J Am Podiatr Med Assoc 101(4): 360–362, 2011)

6073 Background: Recently, we found 6.609 genetic single nucleotide polymorphisms (SNPs) with distinct frequencies between base of tongue squamous cell carcinoma (BTSCC) patients and controls. The study was performed using high-resolution DNA microarrays genotyping (Affymetrix). The SNPs identified never have been previously described with BTSCC risk. Some SNPs of interest were located in genes related to cell cycle (ERP29, LEF1, MCC and PTCH1) and DNA transcription (IKBKAP and ZNF415) and they were selected to validation process. Objective: Validate the SNPs ERP29 c.*293A>G (rs7114); LEF1 c.*1213A>G (rs2107028) and g.127267A>G (rs4245926); MCC c.*5077A>G (rs7033); PTCH1 g.27369025G>A (rs16909856) and g.27369324G>A (rs16909859); IKBKAP c.3214T>A (rs3204145) and ZNF415 c.*443A>G (rs3814) associated to BTSCC risk. Methods: Genomic DNA from 49 BTSCC patients and 49 controls was genotyping by TaqMan assays (Applied Biosystems). The differences between groups were analyzed by logistic regression model. Power analysis (PA) was used to verify the effect of sample size on the results obtained. Results: Eight SNPs identified by Affymetrix were validated by TaqMan assays. The frequencies of ERP29 c.*293AG+GG (30 vs 11%, P=0.03; PA=65%), LEF1 c.*1213AA+AG (95 vs 80%, P=0.02; PA=61%) and g.127267AA+AG (93 vs 78%, P=0.02; PA=56%), MCC c.*5077AA+AG (85 vs 64%, P=0.008; PA=67%), PTCH1 g.27369025GG+GA (90 vs 73%, P=0.005; PA=58%) and g.27369324GG+GA (90 vs 73%, P=0.008; PA=58%), IKBKAP c.3214TT+TA (90 vs 72%, P=0.01; PA=62%) and ZNF415 c.*443AA+AG (59 vs 41%, P=0.02; PA=43%) were more common in patients than in controls. Individuals with these genotypes were at 2.9(CI95%: 1.1-8.4), 3.9 (CI95%: 1.4-11.2), 4.0 (CI95%: 1.2-14.7), 3.5 (CI95%: 1.2-11.9), 5.0 (CI95%: 1.7-16.9), 4.5 (CI95%: 1.5-15.2), 4.1 (CI95%: 1.4-12.9), and 3.9 (CI95%: 1.2-13.7)-fold increased risks for BTSCC than others, respectively. Conclusions: Our data present for the first time evidence that inherited abnormalities in ERP29, MCC, LEF1, PTCH1, IKBKAP, and ZNF415 genes may be important determinants of BTSCC.
