ABSTRACT

BACKGROUND: Adult T-cell Leukemia/Lymphoma (ATLL) is classified as a peripheral CD4+ T-cell neoplasm caused by the human T-cell lymphotropic virus type 1 (HTLV-1). Typical symptoms are associated with leukemic infiltration; however, atypical and exaggerated manifestations of verrucous carcinoma have also been described. CASE REPORT: We present here the case of a patient with multiple skin lesions, ischemic necrosis in the hallux and lymphadenopathies. Biopsies were taken, which showed verrucous epidermal carcinoma and cutaneous lymphoma. Splenomegaly and adenopathy in mesentery, retro peritoneum and lymph node chains in the limbs were observed. Bone marrow examination showed findings compatible with T-cell leukemia/lymphoma; and it was ELISA positive for HTLV-1/2. TREATMENT AND OUTCOME: The patient had a good initial response to a CHOP scheme (cyclophosphamide, doxorubicin, vincristine and prednisone) with filgrastim. However, the patient had a relapse and died before the second cycle. CLINICAL RELEVANCE: Comorbidity could lead to the associated risk factors model. According to this model, secondary immunodeficiency caused by HTLV-1 may induce the development of verrucous carcinomas; alternatively, the disease could be due to a correlation between HTLV-1 and the human papillomavirus (HPV).


ANTECEDENTES: La leucemia/linfoma de células T del adulto se clasifica como una neoplasia de células T CD4+ periféricas desencadenada por el virus linfotrópico de células T humanas tipo 1 (HTLV-1). Los síntomas típicos se asocian a la infiltración leucémica; sin embargo, también se ha descrito la manifestación atípica y exagerada de carcinomas verrucosos. CASO CLÍNICO: Se presenta el caso de una paciente con lesiones múltiples en piel, necrosis isquemica del hallux y linfadenopatías. se realizaron biopsias que reportaron carcinoma epidermoide verrugoso y linfoma cutáneo. Se detectó esplenomegalia y adenopatías en mesenterio, región retroperitoneal, y cadenas ganglionares de las extremidades. la medula ósea presentó hallazgos compatibles con leucemia/linfoma de células T y ELISA positivo para HTLV-1/2. TRATAMIENTO Y RESULTADO: La paciente presentó buena respuesta inicial al esquema CHOP (ciclofosfamida, doxorrubicina, vincristina, prednisona) con filgrastim. Sin embargo, presentó recaída de la enfermedad antes del segundo ciclo y falleció. RELEVANCIA CLINICA: La comorbilidad podría conducir al modelo de factores de riesgo asociados. De acuerdo con este modelo, la inmunodeficiencia secundaria causada por HTLV-1 puede inducir el desarrollo de carcinomas verrucosos; Alternativamente, la enfermedad podría deberse a una correlación entre el HTLV-1 y el virus del papiloma humano (VPH).

ABSTRACT

BACKGROUND: Verrucous carcinoma of the vulva is extremely rare. It is a slow growing, low malignant variant of a squamous cell carcinoma with a cauliflower appearance. Women with lichen planus have an increased risk of developing vulval cancer. CASE PRESENTATION: A 79-year-old woman consulted for vulval itching. On clinical examination, a 3-cm large verrucous clitoral cancer in an area of lichen planus was seen. Based on her last clinical examination, the growth was estimated to be 1 cm2 per month with an invasion depth after 6 months of 5 mm. A tumor developing in an area of lichen planus appears to have more aggressive features. This is the first time that the growth of a verrucous carcinoma has been documented in an area of lichen planus. CONCLUSIONS: Clinicians and patients should be aware of the aggressive behavior of cancers developing in areas of lichen planus and adjust their surgical management together with the follow-up strategy.

ABSTRACT

OBJECTIVE: Exophytic oral verrucous hyperplasia (OVH) is a new entity described by an expert working group from South Asia. First reported in Taiwan, there are no reports so far from an Indian population. The aim was to use the microscopic features described by the expert group to differentiate OVH from other oral verruco-papillary lesions in an Indian archive. MATERIALS AND METHODS: In a retrospective multicentre study, using pathology archives, 188 verruco-papillary lesions were retrieved from pathology archives. A proforma listing histopathological criteria for OVH based on published guidelines (Annals of Dentistry, University of Malaya, 2013) was used. Patients' demographic and clinical data were transcribed from patient charts. The Pearson chi-square test was used to determine associations between clinical and histopathological features. RESULTS: Of 188 oral verruco-papillary lesions that were evaluated, based on microscopic features the cases were reclassified as OVH (57), verrucous carcinoma (VC) (84), oral squamous cell carcinoma (16), and other verruco-papillary lesions (31). Both OVH (70%) and VC (60%) showed male predominance and commonly affected buccal mucosa (OVH 74% and VC 57%). Absence of downward growth of the hyperplastic epithelium into lamina propria when compared with the level of the basement membrane of the adjacent normal epithelium was a distinct feature in OVH. Keratin plugging, epithelial dysplasia and subepithelial lymphocytic infiltration were found to be significantly different (P < 0.05) in OVH versus VC. The sample size of other verruco-papillary lesions was insufficient for statistical comparison. CONCLUSION: Apart from the absence of an endophytic growth pattern in OVH, we noted the presence of dysplasia in OVH. This significant observation does institute a debate as to whether this enigmatic lesion could possibly be a precedent of oral squamous or verrucous carcinoma. We propose OVH is a distinct entity in our Indian population and should be considered in the classification of oral potentially malignant disorders.

ABSTRACT

Verrucous carcinoma (VC) is an unusual, well differentiated, and low-grade type of squamous cell carcinoma, characterized by benign histology and cytology but markedly invasive clinical behavior. They have a predilection for squamous mucosae, particularly those of the head and neck region. Many factors have been associated with its pathogenesis, including the presence of previous skin lesions; VC arising from a prosthesis injury is rare. Here we reported a case of VC of oral cavity a particularly very aggressive, arising from prosthesis injury. Regardless of the treatment modality, given new insights into the possible aggressivity of this tumor, radiotherapy associated to chemotherapy may be a more appropriate primary treatment compared with the significant local morbidity associated with surgery.

ABSTRACT

Keratoacanthoma is a well-known, fast-growing, benign squamous epithelial neoplasm that usually presents as a solitary, dome-shaped, pink or flesh-colored nodule developing a central keratin-filled crater. Few authors consider it to be a benign cutaneous tumor whereas others suggest that it should be regarded as a low-grade variant of cutaneous squamous cell carcinoma (SCC). A 21-year-old female presented with a firm, nontender, well-defined plaque with irregular margins measuring about 8 × 4 cm over the dorsal aspect of the right foot along with an exuberant growth from the plaque measuring 4 × 5cm. There was no lymphadenopathy. Systemic examination was within normal limits. Routine investigations, including complete blood counts, liver and renal function tests, urinalysis, chest radiographs, and abdominal ultrasonography, were normal. Histopathological examination of a skin biopsy from the plaque showed features suggestive of keratoacanthoma, whereas exuberant growth overlying the plaque showed features of verrucous carcinoma (a variant of SCC). Thus, it represents a case of SCC arising from a giant keratoacanthoma.

ABSTRACT

Lichen sclerosus is a chronic inflammatory disease that can progress to malignancy. The literature indicates an association with anogenital squamous cell carcinoma and verrucous carcinoma. Two pathogenic pathways, differentiated vulvar and penile intraepithelial neoplasias, which have recently been described in relation to squamous cell carcinoma, are both highly associated with genital lichen sclerosus independently of human papilloma virus (HPV) infection. Furthermore, tumor-promoting molecular changes unrelated to HPV infection have been demonstrated and may explain the malignant potential of lichen sclerosus. The possible relationship between HPV and genital lichen sclerosus currently remains open to discussion, and the prognostic importance of the overlapping of these 2 diseases is still unclear. This review considers the relationship between lichen sclerosus and squamous cell and verrucous carcinomas, the possible oncogenic mechanisms involved, and their possible association with HPV infection.

ABSTRACT

We report a case of verrucous carcinoma of the penis. A 62-year-old man, who presented with penile swelling and pain, was referred to our hospital. Although, penile tumor biopsy revealed no evidence of malignancy, the patient presented with penile swelling and discharge. The penis was surgically resected and urinary diversion was performed. The pathological examination of the resected glans revealed verrucous carcinoma of penis. Furthermore, in situ hybridization revealed human papilloma virus (HPV) infection. This clearly showed that the verrucous carcinoma of the penis resulted from the HPV infection. The patient has survived for 14 months after surgery without local recurrence or metastasis.

ABSTRACT

INTRODUCTION: Since Jean-Nicolas Marjolin reported carcinoma arising in post-traumatic scars in 1828, the term 'Marjolin ulcer' has been applied to malignant changes in burn scars. Although many papers have been published already in this field, there are few reports from Oriental people. METHODS: From 1989 to 2008, there were 11 cases noted as burn scar carcinoma in Chang Gung Memorial Hospital. Ten were reported as squamous cell carcinoma (SCC) and the one was verrucous carcinoma. Most of the cases occurred in the extremities (10/11). RESULTS: Ten cases underwent an operation initially with wide excision and skin graft or local flap for coverage. Forefoot amputation was performed in one patient. One patient received above-knee amputation and adjuvant therapy because recurrent verrucous carcinoma occurred 2 years later. One patient suffered from a new lesion 8 years later and another case had inguinal lymph node metastasis 8 months later. Five patients were lost to follow-up and six cases were tumor-free during the follow-up period. Most scar malignancies are SCC while other cell types are rarer. CONCLUSION: The casual association between burn injuries and a later risk of basal cell carcinoma is questionable. Owing to poor prognosis in advanced scar cancer, the best treatment for scar carcinoma is to prevent the scar from developing repeated ulceration by performing aggressive initial burn wound care: early grafting by surgeons and daily scar care with regular follow-up for patients. This may be why a lower incidence has been noted in recent years.

ABSTRACT

In Japan people affected by leprosy who were forced to admit to national leprosy sanatoria under leprosy prevention/segregation law (1953) have ever been promoted to return to live in community, after destruction of the law in 1996. In this paper two cases are shown with some comments who had already been discharged from leprosy sanatoria and came late to OPD of National Suruga Sanatorium for consultations of their leprosy related conditions. One case is a 60 year-old male who developed squamous cell carcinoma (SCC) from chronic planter ulcer. The other is a 69 year-old female who developed relapse after more than 20 years BI negativity. In these cases, periods until consultation to our clinic were one year and five months, and five years and five months respectively. One reason is that there is no follow-up system of leprosy related conditions for ex-patients in current medical service of Japan. Another reason may be that patients hesitated to consult local doctors for their leprosy related conditions. Since national leprosy sanatoria will come to be closed in near future, services should be available for leprosy related conditions, such as prevention of disability (POD), prevention of worsening disability (POWD), early detection of relapse and leprosy reaction, in general medical service of Japan.

ABSTRACT

Due to migration of different ethnic groups, mainly from Africa and Asia, into Switzerland, many traditional products and habits that have not been seen before were also introduced. Smokeless tobacco (ST)--as one of those habits--is a product of increased use in Switzerland, although no sound epidemiological data are presently available. Numerous studies from North-America, Sweden, Asia and Africa could verify the carcinogenic potency of smokeless tobacco and its effects in the developement of oral cancer and different systemic disorders. For dental professionals and their team it is important to detect ST-associated lesions, and to tell the patients about the potential harmful sequelae of ST products. The present review focusses on the different types of RT products and their effects on oral health.
