Giant basal cell carcinoma (BCC) is a very rare entity. Usually, they occur due to the negligence of the patient. Local or distant metastasis is present in most cases. Here, we present a case of giant BCC that clinically resembled squamous cell carcinoma and demonstrated no metastasis at presentation. 相似文献

Background:
Basal cell carcinoma (BCC) is the most common skin cancer among whites, and several risk factors have been discussed in itsdevelopment and progress. Detection of human papilloma virus (HPV) deoxyribonucleic acid (DNA) BCCs in some studies suggests that the virus may play a role in the pathogenesis of this disease. Several molecular studies showed conflicting reports.Aims:
The purpose of this study was to investigate the association between HPV and BCC using polymerase chain reaction (PCR).Materials and Methods:
HPV DNA detection was done for 42 paraffin-embedded tissue specimens of BCC and 42 normal skin samples around the lesions by PCR using GP5+/GP6+ primers.Results:
HPV DNA was not found in any of the 42 samples of BCC, and only one normal skin sample around the lesions was positive for HPV DNA by PCR.Conclusion:
In this study, no statistically significant difference was seen between the presence of HPV DNA in BCC and normal skin around the lesion, and HPV is not likely to have an important role in pathogenesis of BCC. 相似文献3.

Seborrheic keratoses (SKs) are common epidermal tumors composed of benign keratinocytes. Malignant skin tumors including basal cell carcinoma (BCC) rarely arise within SKs. We report a rare case of an 82-year-old man with nodulocystic BCC that appeared at the center of a scaly hyperpigmented SK that had been presented for more than 10 years. It was histologically confirmed that CK19-positive BCC arose directly from the wall of the pseudohorn cyst, a part of the SK. Nodular and/or cystic BCC also rarely arise within SKs while the most common histologic type of BCC within SKs is the superficial type. Careful observation of SKs is important even though it is rarely a background condition for malignant transformation. 相似文献

Background:
Basal cell carcinoma (BCC) is the most common malignant skin tumor. Although mortality attributable to BCC is not high, the disease is responsible for considerable morbidity. There is evidence that the number of patients who develop more than one BCC is increasing.Aims:
The aim of this study was to elucidate possible risk factors for developing Multiple BCC.Patients and Methods:
Patients with histologically proven BCC (n = 218) were divided into two groups (single BCC and Multiple BCC) according to the number of their tumors and their profile were reviewed. Probable risk factors were compared between these two groups.Results:
Among 33 evaluated risk factors, mountainous area of birth, past history of BCC, history of radiotherapy (in childhood due to tinea capitis), abnormal underlying skin at the site of tumor, and pigmented pathologic type showed significant differences between the two groups.Conclusions:
The high rate of additional occurrences of skin cancers among patients with previously diagnosed BCC emphasizes the need of continued follow-up of these individuals. Those with higher risk require closest screening. 相似文献5.

The use of the topical Imiquimod 5% cream offers a noninvasive, nonsurgical, and an effective option for the treatment of primary small (<2 cm) superficial basal cell carcinoma (sBCC). However, reports about successful treatment of giant (>5 cm) BCC with topical Imiquimod 5% cream are rare. We present our experience in the treatment of two giant tumors (6 × 8 cm2, 5.2 × 4.2 cm2) of BCC on the face with Imiquimod 5% cream, 2 to 3 days/week for 12 weeks. Both the tumors were cured with clinical and pathological evidence, one with 6-year follow-up and the other with 3.5-year follow-up. 相似文献

Context:
Histopathological evaluations can differentiate between clinically resembling trichoepithelioma (TE) and basal cell carcinoma (BCC) unless the biopsy specimens are small or superficial. Previous studies used immunohistochemical evaluation for Bcl-2 and cytokeratin 15 (CK15), in attempts to differentiate between these two entities, with heterogeneous findings.Aims:
This study intended to compare the rate and patterns of Bcl-2 and CK15 expressions between specimens of TE and nodular BCC.Settings and Design:
Case-series including formalin-fixed, paraffin-embedded cutaneous biopsies.Subjects and Methods:
Twenty-two BCC and 12 TE specimens were stained for Bcl-2 and CK15 and examined microscopically. The rate and patterns of expressions were compared between the two groups.Statistical Analysis Used:
Statistical analysis was performed using the statistical software (SPSS version 16.0; SPSS Inc., Chicago, IL, USA), Pearson Chi-square, or Fisher''s exact tests, wherever appropriate.Results:
The two groups were comparable for the expression rate and patterns of Bcl-2 (86.4%: 5 central, 14 diffuse in BCC vs. 83.3%: 2 central, 8 diffuse in TE; P = 0.59 and 0.54 for rate and pattern, respectively). The rate of CK15 expression was significantly higher in TE specimens (66.7%: 4 central, 3 diffuse, 1 peripheral vs. 4.5%: 1 central; P < 0.001). The positive likelihood ratio in distinguishing the two neoplasms was 14.7 (95% confidence interval: 2.1-103.7).Conclusions:
CK15 but not Bcl-2 staining may help in differentiating between BCC and TE even in BCCs with follicular differentiation. 相似文献8.

Ultraviolet radiation is an important risk factor for the development of skin cancers. Melanin is known to protect the skin against harmful effects of ultraviolet radiation. Hence, vitiligo patients are at higher risk of developing such malignancies. But few reports of occurrence of skin cancers in vitiligo lesions suggest that their occurrence in vitiligo is rare. There are reports of development of Squamous cell carcinoma (SCC) in vitiligo lesions, following long-term Psoralen and Ultraviolet-A (PUVA) therapy. But there are no reports of occurrence of SCC in a vitiligo patch located in photo-covered area. We describe a patient with SCC in a vitiligo patch present in photo-covered skin. 相似文献

Subungual tumors are rare in general. Of all tumors, subungual squamous cell carcinoma (SSCC) is the most frequent one. Protean clinical presentations and the lack of awareness of the disease are responsible for an incorrect or delayed diagnosis and subsequent delayed treatment. We have reported here four patients with SSCC who were previously wrongly diagnosed with a benign process and treated unsuccessfully for years. We would like to highlight the need of a biopsy in chronic or recurrent nail lesions that fail to respond to a previous conservative treatment in order to rule out SSCC. 相似文献

The report highlights the occurrence of basal cell carcinoma in a native Indian with oculo-cutaneous albinism, an association not frequently encountered. The clinical and histopathological features, which assisted to form the diagnosis, are outlined. A high degree of suspicion and timely recognition of the potentially aggressive neoplasm, under this unusual circumstance, is the key to its diagnosis. 相似文献

Background
Basal cell carcinoma (BCC) is the most common type of human cancer. Despite the high prevalence of these tumors, there is a lack of reliable epidemiological data in some regions including Iran.Objective
To assess the relationship between BCC subtypes and anatomical distribution in the Iranian population.Methods
There were 876 patients with a single BCC enrolled in this study (March 2007 to March 2010; Razi Dermatology Center, Tehran, Iran).Results
Among 876 patients, 544 were males and 332 females. Of the lesions, 43% were nodular, 32.4% mixed type, 3% superficial and rest of other subtypes. In the lesion location, 58.2% were on the face, 29.2% on scalp, 6.2% on ears, 2.3% on neck, 1.7% on trunk and 1.3% on the extremities. There was no significant difference between male and female in the BCC subtypes, but anatomical distribution of the tumor was different (p=0.002). Most of the trunk-arising BCCs were superficial, and most of the facial BCCs were nodular subtype. Also, most of the BCC subtypes occurred in patients between 40 to 80 years old and mostly on the face and scalp (p=0.04). However, superficial BCCs mostly occurred in younger patients over others (p=0.001).Conclusion
Subtype is associated with a site, independent of gender or age. Also BCCs occurring on the trunk are mostly of the superficial subtype. 相似文献14.

Background:
Early detection of skin cancers by screening could be very beneficial to decrease their morbidity or mortality. There is limited study about skin cancer screening in Iran.Aim:
This essay was planned as a pilot skin cancer screening campaign in Tehran, Iran to evaluate its profit and failure and further design large-scale screening program more definitely.Materials and Methods:
Thirty one public health centers of Shahid Beheshti Medical University were selected in different areas of Tehran. The project was announced via media and invited all the people above 40 years old to come for the whole-body skin examination in a one-week period. Patients with any suspected lesions were referred to the dermatology clinics of the university.Results:
1314 patients, 194 males (14.8%) and 120 females (85.2%), with mean age of 51.81 ± 10.28 years participated in this screening campaign. Physicians found suspected lesions in 182 (13.85%) of participants. The diagnosis of skin cancer was confirmed in 15 (1.14%) patients. These malignancies included 10 (0.76%) cases of basal cell carcinoma, 2 (0.15%) cases of squamous cell carcinoma and 3 (0.23%) cases of malignant melanoma.Conclusion:
Skin cancer screening seems to be valuable to detect skin malignancies in their early course. Regarding the considerable amount of facilities needed to perform skin cancer screening program, it might be more beneficial to perform the targeted screening programs for the high-risk groups or emphasis more on public education of skin cancer risk factors and their early signs. 相似文献15.

Basal cell carcinoma (BCC) is one of the most commonly diagnosed malignant skin tumors and develops characteristically on sun-exposed areas, such as the head and neck. Ultraviolet light exposure is an important etiologic factor in BCCs, and BCCs arising from non-sun- exposed areas are, therefore, very rare. In particular, the axilla, nipple, the genital and perianal areas are not likely to be exposed to ultraviolet light; thus, if BCC develops in these areas, other predisposing factors should be considered. Herein, we report a case of BCC arising on the pubic area in a 70-year-old man. We also performed a survey of the literature and discussed the 19 cases of BCC from non-sun-exposed areas reported to date in Korea. 相似文献

Although basal cell carcinoma is the most common skin cancer, it rarely metastasizes. Metastatic basal cell carcinoma may, therefore, initially elude diagnosis and management. We describe the case of a patient with a metastatic basal cell carcinoma present in the lungs. The differential diagnosis of suspected metastatic lesions should include metastases from a cutaneous basal cell carcinoma, in addition to those from more commonly metastasizing carcinomas, especially in patients with a history of a large basal cell carcinoma that has involved the head and neck regions, and was refractory to treatment. 相似文献

Primary lymphoepithelioma-like carcinoma of the skin (LE-lCS) is a very rare cutaneous malignancy of uncertain origin. The neoplasm reveals typical morphological similarity to undifferentiated nasopharyngeal carcinoma (lymphoepithelioma). This case report presents a 47-year-old man with a 5 mm erythematous papule on dorsal nose of six months duration. The patient underwent complete surgical excision and is disease free 7 months later. 相似文献

Vulvar basal cell carcinoma (BCC) is rare, accounting for less than 5% of all vulvar neoplasms and less than 1% of all BCCs. Vulvar BCCs are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They may be invasive and destructive if neglected or improperly treated. Nevertheless, they have a very low propensity for metastatic spread, but frequently recur after simple excision. We report a 78 year-old woman presenting with the complaint of painful vulvar ulceration and vaginal bleeding. The physical examination revealed a 3 × 2 cm indurated nodulo-ulcerative lesion involving the clitoris, both labia minora and left labium majus. The histopathology was consistent with the “solid type BCC” that invaded the subcutaneous tissue without lymph node metastasis. The patient underwent wide local excision with clitoral amputation and remained disease free at post-surgical follow-up after 18 months. 相似文献
