Oral keratotic white lesions are a common problem that is encountered on routine clinical examination. Clinical appearance of the lesion may belie the true nature of the lesion. So a biopsy followed by histopathological diagnosis is the gold standard in evaluating these lesions for malignant potential or dysplasias. Objective: The aim of the present study is to evaluate the clinicopathologic findings of oral keratotic lesions. Materials and Methods: Oral biopsies of 61 cases of oral keratotic white lesions during the period from January 2006 to July 2009 were studied retrospectively at the Department of Pathology, Kasturba Medical College, Manipal by microscopy. Clinical details and records were obtained from the medical records department. Results: In 61 cases of oral keratotic white lesions the age distribution ranged from 29 to 86 years. 66% were males while 34% were females and most lesions occurred between 31 and 70 years. The buccal mucosa was the most common site of lesion in 35% patients. Only 15 cases had some personal habits and 8/15 cases (53%) showed dysplasia. 12/ 54 cases (22%) of homogenous leukoplakia displayed dysplasia, of which 11 cases (92%) showed mild dysplasia and 1 case (8%) showed moderate dysplasia. Of the 4 cases of speckled leukoplakia, 75% showed dysplasia- mild, moderate and severe. 2/3 cases (66%) of verrucous leukoplakia displayed dysplasia- moderate and severe. There were 41 cases consistent with leukoplakia (67%), of which 22% showed epithelial hyperplasia and hyperkeratosis, 12 cases showed mild dysplasia, 3 cases moderate dysplasia and 2 cases showed severe dysplasia. Benign keratosis formed the largest group (35%) among the 61 cases. Of the 61 cases 17 (27%) showed dysplasia of which 19% was mild dysplasia, 5% was moderate dysplasia and 3% was severe dysplasia. Most frequent histomorphological feature seen in this study was nuclear pleomorphism in 21/ 27 cases (78%). There were 12 cases (71%) of dysplasia in males and 5 cases (28%) of dysplasia in females. There was 1 case of Progressive verrucous leukoplakia   in an 86 year old female patient. There were 3 cases (5%) each of oral lichen planus, lichenoid dysplasia and lichenoid keratosis in the present study. 6 cases (9%) of candidiasis was seen among the 61 biopsies. In the study there was 1 case (2%) each of verrucous  carcinoma, squamous cell carcinoma and micro-invasive squamous cell carcinoma. Conclusions: Oral keratotic white lesions demonstrate a wide spectrum of histopathological features from benign lesions to dysplastic lesions to carcinoma in situ to invasive ones.

Sir, Cutaneous squamous cell carcinoma, a malignant proliferation of the cutaneous epithelium, represents the second most common non-melanoma skin cancer after basal cell carcinoma [1]. Verrucous carcinoma (VC) is a rare, low-grade, well-differentiated squamous cell carcinoma most commonly seen in the mucosa, infrequently reported to occur in the skin, where it is a slow-growing and locally aggressive tumor. It is not uncommon for cutaneous verrucous carcinomas to be mistaken for the more frequent wart (verruca vulgaris) and treated accordingly [2]. The etiopathogenesis of VC is not completely known. One theory mentions the human papillomavirus (HPV) infection; with plantar lesions, the types involved are reported to be 16 and 11 [3]. Histopathological diagnosis is difficult and needs one or more broad and in-depth biopsies. Morbidity results from the local destruction of the skin and soft tissues and, occasionally, from a perineural, muscular, and even bony invasion. Metastasis to regional lymphatic ganglia is rare, found in 5% of cases [4]. VC bears a high risk of local relapse. No matter the treatment employed, the rate of recurrence varies from 30% to 50% and usually is not the result of incomplete surgical interventions. The treatment of choice is complete surgical excision with safety margins [5]. A forty-year-old female patient with no previous history presented herself with a hyperkeratotic lesion on the right foot persistent for two years, which she had been manipulating routinely, which had progressively been increasing in size for the previous year, and which, for the previous three months, had become painful and bleeding. An examination revealed a hyperkeratotic plaque with a hyperpigmented border, hard on palpation, adherent to the deep plane, and with an eroded surface (Fig. 1). Dermoscopy was able to find a papillomatous appearance surrounded by dotted vessels (Fig. 2). This dermoscopic aspect typical of vulgar warts was confusing. Indeed, dermoscopy of the foot wart shows red or black dots in the center of papillomatous structures, which are thrombosed vessels supplying the wart; hence the importance, in our opinion, of the clinical and pathological correlation. For this reason, we performed a skin biopsy; an anatomopathological study found a squamous cell carcinoma of the verrucous type.

Despite the recognized link between aging and cancer, most preclinical studies in experimental tumor models are conducted with 6- to 8-wk-old rodents. The goal of the present study was to examine the impact of age on tumor incidence, growth, and microenvironmental characteristics in mouse models of head and neck squamous cell carcinoma (HNSCC). Experimental studies were conducted with the 4-nitroquinoline-oxide (4NQO) oral carcinogenesis model and orthotopic FaDu HNSCC xenografts, established in young (7 to 12 wk of age) and old (65 to 70 wk of age) female C57BL/6 mice ( n = 44; 4NQO model) and severe combined immunodeficient mice ( n = 13; HNSCC xenografts). Noninvasive whole body magnetic resonance imaging revealed increased subcutaneous and visceral fat in aging animals of both strains. On histologic examination, a higher incidence ( P < 0.001) of severe dysplasia/invasive squamous cell carcinoma was observed in old mice (92%) as compared with young mice (69%). Old C57BL/6 mice exposed to 4NQO exhibited increased incidence of oral and extraoral (peritoneal masses) neoplasms (42%) versus their young counterparts ( P < 0.05). The incidence of extraoral neoplasms was significantly lower (16%) in the younger cohort. Interestingly, no difference in growth rate and oxygen saturation was observed between orthotopic FaDu xenografts established in old and young severe combined immunodeficient mice. Our observations suggest that host age may have an impact on the growth kinetics and progression of HNSCC in the immunocompetent 4NQO model. Further investigation into the impact of aging on tumor response to preventive and therapeutic intervention is warranted.

Abstract Background. Microinvasive squamous cell carcinoma (MISCC) comprises a significant portion of all cervical cancers in Slovenia. Criteria of carcinomatous invasion are well described in the literature, however histopathological assessment of MISCC is difficult, because morphological characteristics can overlap with cervical intraepithelial neoplasia grade 3 (CIN 3) and other pathological changes. The aim of our study was to evaluate the reliability of the histopathological diagnosis of MISCC in Slovenia during the period from 2001 to 2007. Materials and methods. Data on patients with a histopathological diagnosis of cervical MISCC (FIGO stage IA) in the period of 2001 to 2007 were obtained from the Cancer Registry of Slovenia. Histological slides were obtained from the majority of pathology laboratories in Slovenia. We received 250 cases (69% of all MISCC) for the review; 30 control cases with CIN 3 and invasive squamous cell carcinoma FIGO stage IB were intermixed. The slides were coded and reviewed. Results. Among 250 cases originally diagnosed as MISCC, there was an agreement with MISCC diagnosis in 184 (73.6%) cases (of these 179/184 (97.3%) cases were FIGO stage IA1 and 5/184 (2.7%) cases were FIGO stage IA2). Among 179 FIGO stage IA1 cases 117 (65.4%) showed only early stromal invasion. Conclusions. The retrospective review of cases diagnosed as MISCC during the period 2001- 2007 in Slovenia showed a considerable number of overdiagnosed cases. Amongst cases with MISCC confirmed on review, there was a significant proportion with early stromal invasion (depth of invasion less than 1 mm).

Background: Oral squamous cell carcinoma is the 6th most common malignancy in the world and ranks as first in males in Indian sub-continent. Vimentin is an intermediate filament found in mesenchymal cells and e-cadherin is an adhesion molecule found in epithelial cells. The objective of the study is to evaluate the expression of e-cadherin and vimentin in lesions of oropharynx and to assess the sensitivity, specificity and positive predictive value of e - cadherin and vimentin in oropharyngeal squamous cell carcinoma (OPSCC), against routine H and E stained histopathological diagnosis.Methods: 100 oropharyngeal biopsy specimens taken and routine H and E stained histopathological slide diagnosis made. E-cadherin and vimentin expression studied in OPSCC, moderate to severe dysplasia, mild dysplasia and benign cases and its sensitivity, specificity, positive predictive value and negative predictive value analysed using appropriate statistical tools.Results: Vimentin positivity was observed in 70 out of 79 OPSCC, 2 out of 3 cases of moderate - severe dysplasia, 0 out of 2 mild dysplasia and 2 out of 16 benign lesions. Out of 79 cases of OPSCC, 15 were e-cadherin negative, 27 showed low and 37 cases showed high membraneous positivity.Conclusions: We observed a significant decrease in e-cadherin membrane expression from dysplasia to carcinoma insitu to invasive carcinoma and a significant increase in vimentin expression with progression of the tumor. E-cadherin is a good prognostic marker whereas vimentin expression indicates a poor prognosis.

Abstract Verrucous carcinoma (VC) is a rare variant of a well-differentiated squamous cell carcinoma (SCC) with a low grade of malignancy. Epithelioma cuniculatum (EC) is a subtype of VC, usually found on the sole of the foot. Two patients, a 55-year-old female, and a 77-year-old male, with VC were treated at the Clinic of Dermatology and Venereology, Clinical Center of Serbia, from 2002 to 2011. Both patients presented with a tumor on the foot. Incisional biopsies showed a well differentiated squamous cell carcinoma. Foot x-rays showed bone involvement in one case. One patient underwent surgical amputation of the lower extremity, while the other had a partial amputation of the affected foot. In the initial stage of the disease, it is difficult to distinguish pseudoepitheliomatous hyperplasia from verrucous carcinoma. The superficial biopsy of EC lesion may mislead to a histopathological diagnosis of warts or condylomas. Multiple deep biopsies are necessary for accurate and timely diagnosis of verrucous carcinoma.

Oral cancer is a significant cause of morbidity and mortality worldwide. In this article we present two cases of potentially innocuous looking lesions, initially thought to be traumatic in origin, but later diagnosed as cancer. The first patient presented with a persistent laceration thought to be caused by an accidental shaving injury, which was subsequently diagnosed as squamous cell carcinoma. The second patient presented with a hyperplastic mucosal lesion, suspected as forming due to denture-clasp irritation, which was subsequently diagnosed as proliferative verrucous carcinoma. The importance of early detection and palpation of suspicious lesions is emphasised in this article.
