1/968. Basal cell carcinoma with massive ossification.We report a case of basal cell carcinoma with massive ossification in a 66-year-old white man. Ossification in various benign and malignant neoplasms have been reported including basal cell carcinomas, in which ossifications are seen in small foci or peripheral rim of the tumor. However, in our case, massive ossification is seen throughout the tumor, and only small areas of the periphery of the tumor show diagnostic histology. Therefore, this case might have presented a diagnostic difficulty or been misdiagnosed as an osteoma cutis if a smaller incisional or punch biopsy had been performed. The phenomenon of bone formation itself is not specific for any diagnostic entity, and therefore an underlying lesion should be carefully sought in case of secondary ossification.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/968. Basal cell carcinoma of the eyelids: a review of patients treated by surgical excision.A study of 107 cases of basal cell carcinoma involving the eyelids in 106 patients all treated by surgical excision was undertaken. The lesions were found predominantly in Caucasians, showed no sex predilection (except for the fact that all five cases under age 40 occurred in females), and were most prevalent in the 7th decade of life. The most common presenting symptom was a mass or growth, while the duration of symptoms of any kind referable to the tumor was 20 months. The lower lid was the most common site of involvement, followed in order of frequency by the upper lid, medial canthus, and lateral canthus. Excised lesions that show marginal involvement histopathologically will not necessarily clinically recur, although this study did show that incomplete excision will more likely show a clinical recurrence in previously treated rather than primary lesions. If basal cell carcinomas of the eyelid are fully surgically excised as a first procedure, the patient will have about a 99% cure rate. Lesions requiring orbital exenteration are rare.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
3/968. Microvascular reconstruction of the skull base: indications and procedures.PURPOSE: The aim of the current study was to review the use of free tissue transfer for reconstruction of the skull base and for coverage of intracranial contents. patients AND methods: From 1990 until 1996, revascularized flaps were transferred to the skull and the skull base in 11 patients in whom intracranial/extracranial resection of tumors of the skull base was performed in cooperation with the Department of neurosurgery. The defects resulted from removal of squamous cell carcinomas (n = 4), basal cell carcinomas (n = 4), malignant melanoma, malignant schwannoma, and malignant meningioma. Defect repair was accomplished by revascularized transfer of latissimus dorsi muscle flaps in seven cases and rectus abdominis flaps and forearm flaps in two cases each. In five patients with extensive intracranial tumor spread, reconstruction was performed for palliative reasons. RESULTS: A safe soft tissue closure of the intracranial and intradural space was achieved in all patients, whereas the contour of the facial skull and the neurocranium was satisfactorily restored at the same time. By using the entire length of the grafted muscle, the vascular pedicle could be positioned next to the external carotid artery and conveniently connected to the cervical vessels. The mean survival time of the patients with palliative treatment was 8.4 months, with an average duration of hospital stay of 24.5 days. CONCLUSIONS: Despite the increased surgical effort of revascularized tissue transfer, microvascular reconstruction of large skull base defects appears to be justified, even as a palliative measure.- - - - - - - - - - ranking = 0.33333333333333keywords = carcinoma (Clic here for more details about this article) |
4/968. Mohs' surgery as an approach to treatment of multiple skin cancer in rhinophyma.BACKGROUND: Skin cancer arising within a rhinophyma is rare, less than would be expected from the coexisting chronic active inflammatory process. In rhinophyma, multiple coexisting tumours of different histologic types present an unusual challenge and have never been described in the literature. OBJECTIVE: The treatment approach to multiple tumours occurring in rhinophyma, utilizing Mohs' surgery, is reported and discussed. PATIENT: The case of a 64-year-old farmer with basal cell carcinoma, squamous cell carcinoma, and basosquamous carcinoma occurring in the setting of longstanding rhinophyma is described. CONCLUSION: Skin cancer, especially basal and squamous cell carcinoma, diagnosed simultaneously in a rhinophyma creates a challenge; the enlarged, inflamed, and hypertrophied tissue masks their margins. In our opinion, Mohs' micrographic surgery is the treatment of choice and should be primarily considered in view of the malignant potential of these tumours, as is shown by the substantial tumour extension in the case described.- - - - - - - - - - ranking = 0.66693545817096keywords = carcinoma, cancer (Clic here for more details about this article) |
5/968. Basal cell carcinoma: what dentists need to know.BACKGROUND: Basal cell carcinoma, or BCC, is a malignant epithelial tumor of the skin, commonly seen in the head and neck. Because dentists routinely evaluate the head and neck, the authors present three examples of BCC of the face and jaw to help clinicians recognize the condition. They also provide a literature review regarding BCC's etiology, classification, treatment and prevention. DESCRIPTION OF THE disease: Sun exposure plays an important role in the development of BCC. The most susceptible people are those with minimal skin pigmentation. BCC is more frequently seen in men than in women. The most common form of BCC is the nodular type, which, if untreated, eventually ulcerates and may result in extensive local tissue destruction. The three cases described in this article highlight the range of BCC severity. CLINICAL IMPLICATIONS: oral health care providers may play an important role in the recognition and diagnosis of BCC involving the head and neck. Early recognition and diagnosis may lead to management that results in improved cure rates, with reduced morbidity and reduced treatment costs.- - - - - - - - - - ranking = 0.83333333333333keywords = carcinoma (Clic here for more details about this article) |
6/968. Basal cell carcinoma with lung metastasis diagnosed by fine-needle aspiration biopsy.Basal cell carcinoma of the skin is one of the most common types of cancer. Its natural history is one of local recurrence rather than metastatic spread. Certain histologic features and primary tumor size seem to be risk factors for metastases. The diagnosis of metastatic disease imparts a poor prognosis with a short median survival. Treatment is usually in the form of systemic chemotherapy with cisplatin-based combination described as most active agent.- - - - - - - - - - ranking = 0.83342390623964keywords = carcinoma, cancer, lung (Clic here for more details about this article) |
7/968. Nevoid basal cell carcinoma syndrome.A case report of a young girl with nevoid basal cell carcinoma syndrome is presented. The patient showed cutaneous and skeletal findings characteristic of the syndrome. Multiple basal cell carcinomas, rib abnormalities, along with clinical evidence of frontal bossing and ocular hypertelorism were the primary features of the syndrome in this patient. It is suggested that other characteristics of the syndrome, such as jaw cysts, palmar and plantar pitting and calcification of the falx cerebri will develop as the patient grows older. Careful observation, particularly for medulloblastoma and malignant degeneration and invasiveness of basal cell carcinomas, will be an integral part of this young patient's care.- - - - - - - - - - ranking = 1.1666666666667keywords = carcinoma (Clic here for more details about this article) |

Systemic sarcoidosis presenting with multiple tattoo granulomas and an extra-tattoo cutaneous granuloma.We describe a 29 year old Caucasian man who developed cutaneous sarcoidosis manifesting itself as a tumour at the left outer canthus clinically mimicking a basal cell carcinoma and nine tattoo granulomas. Subsequent investigation revealed that the patient was also suffering from systemic sarcoidosis.- - - - - - - - - - ranking = 0.16666666666667keywords = carcinoma (Clic here for more details about this article) |
9/968. Basal cell carcinoma or not? Histological variants and mimics of the most common cutaneous malignancy.Basal cell carcinomas are the most common cutaneous malignancy encountered by dermatologists. Although most basal cell carcinomas have typical features and are easily diagnosed histologically, some basal cell carcinomas are problematic. Because the best evidence suggests that basal cell carcinomas arise from primitive stem cells that differentiate along follicular lines, it is not uncommon that this tumor may resemble and be confused with a variety of benign and malignant follicular and sweat gland tumors. This article will focus on some common and rare histological variants that may produce confusion, as well as salient features that will allow the correct diagnosis to be made.- - - - - - - - - - ranking = 1.3333333333333keywords = carcinoma (Clic here for more details about this article) |
