1/173. 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 = 1keywords = cancer (Clic here for more details about this article) |
2/173. Collagenous fibroma (desmoplastic fibroblastoma).Collagenous fibroma (desmoplastic fibroblastoma) is a recently described tumor that may arise in the subcutaneous tissue or skeletal muscle. We report a case of collagenous fibroma, occurring on the forehead of a 67-year-old man. An awareness of this entity is necessary to avoid confusion with other soft tissue neoplasms, especially extraabdominal fibromatosis.- - - - - - - - - - ranking = 0.81662433222611keywords = neoplasm (Clic here for more details about this article) |
3/173. Cutaneous malignant melanoma: Tabuk experience.Cutaneous melanoma (CM) has a rising morbidity and mortality in the western world but is rare in certain geographical areas including the middle east. The aim of this study is to define the pattern of CM in this environment over a period of about two decades. A review of associated histological reports, dermatology, plastic general surgical admissions and outpatient census statistic of the North West Military Hospital (N.W.A.F.H.) were carried out from January 1978 to June 1996. The clinico-therapeutic information from both the review case and newly discovered CM was then studied. The result shows that CM is probably rare in the Tabuk military environment and possibly has a low mortality among the affected individuals. The presence of only 2 cases of CM among 73,955 patients over about 20 years suggests that this neoplasm is rare in N.W.A.F.H. Surgery, with localised expert reconstruction, probably offers the best cure for uncomplicated CM in this area. It is suggested that the geographical environment, genetic attributes, custom, attitude, presence of white, painted, sun-reflecting buildings, traditional dress-code and behaviour of the indigenes probably contribute to the suppression of and protection against CM in Tabuk. It is recommended that regular, antimlanoma education awareness programmes among the indigenes and avoidance of sunbathing attitude of the expatriate community should be encouraged in order to maintain this suggested natural selection protection.- - - - - - - - - - ranking = 0.81662433222611keywords = neoplasm (Clic here for more details about this article) |
4/173. Subcutaneous leiomyosarcoma on the face.BACKGROUND: Cutaneous leiomyosarcoma is a rare soft tissue sarcoma with a predilection for the lower extremities. leiomyosarcoma of the face is very rare. Subcutaneous leiomyosarcoma has a higher likelihood of recurrence and metastases than that of the superficial dermal type. OBJECTIVE: The dermatologic surgeon and pathologist should be familiar with the characters of subcutaneous leiomyosarcoma. methods: We report a case of subcutaneous leiomyosarcoma on the face with the results of histologic examination and immunohistochemical studies. RESULTS: leiomyosarcoma of the face is exceedingly rare. The deep subcutaneous type is thought to arise from the smooth muscle of the vascular wall. The neoplasm we report here has deep tumor invasion, high malignancy grade (3B), and large tumor size. Wide excision and postoperative radiotherapy were performed. CONCLUSION: Subcutaneous leiomyosarcoma has a higher likelihood of recurrence and metastases than that of the superficial dermal type. The most effective treatment is wide excision with 3-5 cm lateral margins and a depth that includes subcutaneous tissue and fascia.- - - - - - - - - - ranking = 0.81662433222611keywords = neoplasm (Clic here for more details about this article) |
5/173. An unusually aggressive trichoblastoma.Trichogenic tumors are neoplasms of the hair germ cell that usually exhibit benign behavior. We describe a case of a large invasive trichoblastoma requiring Mohs micrographic surgery for its removal. Immunohistochemical studies performed demonstrate overlapping features of this trichogenic tumor with basal cell carcinoma.- - - - - - - - - - ranking = 0.81662433222611keywords = neoplasm (Clic here for more details about this article) |
6/173. Tumor implantation at the flap donor site: a case report.The genesis of cancer and its variable patterns of spread have been theorized and debated upon for decades. Recurrences, both local and metastatic, are dreaded by both the patient as well as the surgeon. An interesting case of tumor implantation at the flap donor site was noted in a patient who underwent a primary flap reconstruction for cancer of the cheek. The details of the case and theories regarding tumor implantation have been enumerated in this report.- - - - - - - - - - ranking = 0.33333333333333keywords = cancer (Clic here for more details about this article) |
7/173. Serial excision of a large facial skin cancer.BACKGROUND: In the management of large facial neoplasms, the dermatologic surgeon must consider local factors affecting the success of closures. OBJECTIVE: Large facial neoplasms can be removed serially with Mohs micrographic surgery. Serial excision facilitates recruitment of adjacent normal skin for replacement of lesional skin, minimizing the risks of necrosis. methods: A large morpheaform basal cell carcinoma was excised serially. The initial defect was closed with an O to L advancement flap. The final excision and repair 2 months later consisted of a combination of primary closure with marsupialization and pursestring closure. A full-thickness skin graft was used to close the final defect. RESULTS: The patient had optimal cosmesis at 2-year follow-up. CONCLUSION: Large facial neoplasms can be excised serially. This technique, performed in the setting of Mohs micrographic surgery, takes advantage of "mechanical and biologic creep," resulting in excellent cosmesis and function.- - - - - - - - - - ranking = 3.116539663345keywords = neoplasm, cancer (Clic here for more details about this article) |
8/173. Basal cell carcinoma metastatic to the parotid: report of a new case and review of the literature.Basal cell carcinoma is the most common of the cutaneous malignancies, accounting for 65 to 75% of all skin cancers. The natural history of this disease is one of chronic local invasion. Metastatic basal cell carcinoma is a rare clinical entity, with a reported incidence of only 0.0028 to 0.5%. Approximately 85% of all metastatic basal cell carcinomas arise in the head and neck region. We present a case of basal cell carcinoma that spread to the parotid gland in a man who had multiple lesions on his scalp and face. We also review the literature on metastatic basal cell carcinoma of the head and neck, and we discuss its epidemiology, etiology, histopathology, and treatment.- - - - - - - - - - ranking = 0.16666666666667keywords = cancer (Clic here for more details about this article) |
9/173. Perineural spread leading to orbital invasion from skin cancer.Orbital and intracranial invasion from skin cancer is an uncommon but serious consequence of skin cancer located around the orbit, particularly the forehead. Perineural spread is an aggressive manifestation of skin cancer similar to lymph node metastases. Such spread can provide access to the orbit and squamous cell carcinoma is the most common histology reported. Treatment should be directed at preventing such orbital spread. Adjuvant radiotherapy is strongly recommended. disease may present in an advanced state within the orbit or beyond the orbital apex and involve the cavernous sinus. Palliative radiotherapy should be considered in such advanced cases. Presented are the cases of four patients treated for advanced orbital and intracranial spread from periorbital skin cancer.- - - - - - - - - - ranking = 1.3333333333333keywords = cancer (Clic here for more details about this article) |
10/173. Invading basal cell carcinoma of the jaw: an under-evaluated complex entity.Basal cell carcinoma (BCC) is a locally invasive neoplasm, rarely metastatic, yet capable of significant local destruction and disfigurement. Invasion into the bone is uncommon and only a few cases of invasion into facial bones, but never to the mandible or maxilla, have been described. We report three patients with BCC lesions invading their jaws, as a consequence of which either their mandible or maxilla had to be partially resected. This resulted in facial mutilation which required comprehensive multi-disciplinary therapy to restore function and esthetics. Such therapy requires a combination of modalities offered by both plastic and maxillofacial surgeons, as well as oral and dental rehabilitators.- - - - - - - - - - ranking = 0.81662433222611keywords = neoplasm (Clic here for more details about this article) |
